The technical field to which the invention relates

The following description in General refers to wireless, and more specifically to the performance of the reference signal for legacy support, custom equipment in LTE A.

The level of equipment

Wireless systems are widely used to provide various types of communication. For example, voice and/or data can be provided through such systems wireless communications. A typical system or wireless communications network can provide access by multiple users to one or more shared resources (e.g., bandwidth, power transmission...). For example, the system can use a number of methods, multiple access, such as multiplexing frequency division (FDM), multiplexing time division (TDM), multiplexing code division (CDM), multiplexing orthogonal frequency division (OFDM) and others.

In General, wireless communication systems, multiple access can promote the exchange of information for multiple mobile devices simultaneously. Each mobile device can communicate with one or more base stations by means of transmission by direct and reverse links. Direct link (or descending line of communication refers to communication lines basic stations of mobile devices, and the reverse link (or ascending line of communication refers to communication lines mobile base stations.

Wireless communication systems often use one or more base stations, which provide the service area. Typical base station can transmit multiple streams of data for broadcast, multicast, and/or unicast services, and the data flow may be a stream of data, which may be of independent interest reception for the mobile device. Mobile device in a service area of such base station can be used to receive one, more than one or all the data streams transmitted multipart stream. Also, the mobile device may send data to the base station or other mobile device.

Multiple transmit antennas in wireless systems furthers achievement explode transmission and/or a higher speed transfer of data. Passing the transfer relates to increasing the performance obtained when the signal is sent several times at different transmitting antennas. The basic idea is that when the gains of channels from different transmit antennas are independent, the probability that the gain bandwidth from different transmitting antennas for user equipment (UE) is a small decrease together exponentially when the number of transmit antennas increases. The possibility of failure in this case is approximately equal to p^Nt, where p is the probability of failure when used with only one transmit antenna, and Nt is the number of transmit antennas. On the other hand, if the signal was sent from the same antenna several times, if the channel was bad in the first case, it is likely that it will be bad for the rest of the gear, and so the probability of failure continues to be equal to p (approximately).

The implementation of the invention

Different variants of realization are described below, with reference to the drawings, in which the same reference positions are used to refer to the same elements throughout the description. In the following description for clarification outlines the many special details to provide a comprehensive understanding of one or several variants of implementation. However, it may be obvious that such(s) option(s) may be applied(s) in practice without these special details. In other cases, widely known patterns and devices are shown in the block schemes to simplify the description of one or several variants of implementation.

Described in this document methods can be used for various wireless communication systems, such as multiple access code division (CDMA), multiple access time division (TDMA), multiple access frequency division (FDMA), multiple access with orthogonal frequency division (OFDMA)and multiple access frequency division on single-carrier (SC-FDM) and other systems. The terms "system" and "network" are often used interchangeably. The CDMA system can implement wireless communication technology, such as universal terrestrial radio access (UTRA), CDMA2000, etc. UTRA incorporates wideband CDMA (W-CDMA) and other types of CDMA. CDMA2000 covers standards is-2000, is-95 and is-856. The TDMA system can implement wireless communication technology, such as global system for mobile communication (GSM). The OFDMA system can implement wireless communication technology, such as the enhanced UTRA (E-UTRA), ultra-wideband mobile communication (UMB), IEEE 802.11 (Wi-Fi)IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDM, etc. UTRA and E-UTRA are part of the universal mobile telecommunications system (UMTS). The system of long-term evolution (LTE) 3GPP is the upcoming release of UMTS, which uses E-UTRA, which uses OFDMA on the downlink and SC-FDMA on the ascending line.

SC-FDMA uses a single carrier modulation and correction in the frequency domain. SC-FDMA has similar performance and is essentially the same overall complexity, as OFDMA system. Signal SC-FDMA has a lower peak-to-average power (PAPR) because of its inherent structure with a single carrier. SC-FDMA can be used, for example, in broadcasts in the ascending line of communication, where more low PAPR is very helpful to access terminals in terms of the efficiency of power transmission. Accordingly, SC-FDMA can be implemented as a collective access in the ascending line of communication in the system of long-term evolution (LTE) 3GPP or in an improved UTRA.

In addition, this document describes different ways of implementation with regard to a mobile device. A mobile device may also be called " system, subscriber module, subscriber station, mobile station, mobile, remote station, remote terminal, terminal access, user terminal, a terminal, a wireless device, the user agent, the user device or user equipment (UE). A mobile device can be the cell phone, wireless phone, telephone, Internet Protocol session initiation (SIP), the station as a wireless local communication systems (WLL), personal digital assistants (PDAs), handheld device that has a wireless connection, computer or other processing device connected to a wireless modem. In addition, different variants of realization are described in this document in relation to the base station. The base station can be used to interact with a mobile device (devices) and may also be called an access point, Hub or B to determine some other terminology.

Furthermore, different aspects or characteristics described in this document can be implemented in the form method, device, or product using standard software and/or technical methods. The term "product" when used in this document is designed to include computer software, accessible from any machine-readable device, carrier or carriers. For example, machine-readable carriers may include, but are not limited to, magnetic storage device (e.g. hard disk, floppy disk, magnetic tape, etc.), optical disks (such as CD-ROM (CD), digital versatile disc (DVD) etc.), smart card and a flash memory device (for example, EPROM, memory card, USB flash drive," and so on). Moreover, the various media, described in this document, can represent one or more devices and/or other machine-readable form for information storage. The term "machine-readable medium" may include, without being limited, wireless channels, and various other media, allowing for the storage, maintenance and/or move commands (teams) and/or data.

Figure 1 illustrates the system is 100 wireless in accordance with different variants of implementation presented in this document. The system contains 100 base station 102, which may include multiple antennas. For example, one group of antennas may include antenna 104 and 106, another group may contain antenna 108 and 110, and an additional group may include antenna 112 and 114. For each group of antennas are illustrated with two antennas; however, for each group, there may be more or less antennas. Base station 102 may additionally include the circuit of the transmitter and the circuit of the receiver, each of which in turn can contain many components associated with the transmission and reception of a signal (for example, processors, modulators, multiplexers, demodulators, demultiplexes, antennas, etc. that will be understood by a person skilled in the art.

Base station 102 can communicate with one or several mobile devices such as mobile device 116 and mobile device 122; however, we must take into account that the base station 102 can communicate with virtually any number of mobile devices, similar mobile devices 116 and 122. Mobile device 116 and 122 can be, for example, cellular phones, smartphones, laptops, handheld communications devices, handheld computing devices, satellite radio stations, global positioning systems, PDA's and/or any other suitable device for interaction in the system of 100 wireless communications. As depicted, the mobile device is 116 in cooperation with antennas 112 and 114, where the antenna 112 and 114 pass information to the mobile device 116 in a straight line 118 connection and receive information from a mobile device 116 on a return line 120 communication. In addition, the mobile device 122 is in conjunction with antennas 104 and 106, where the antenna 104 and 106 pass information to the mobile device 122 in a straight line 124 communication and accept the information from mobile devices 122 on a return line 126 communication. In duplex system with frequency division (FDD) direct line 118 of communication can be used, for example, a different frequency band than using a reverse line 120 connection, and the straight line 124 communication may take a different frequency band than a back line 126 communication. In addition, in duplex system time division (TDD) direct line 118 communication and return line 120 connection can use a common frequency band and the straight line 124 communication and return line 126 connection can use a common frequency band.

Each group of antennas and/or region in which they are designed to interface may be called by sector base station 102. For example, groups of antennas can be designed to interact with mobile devices in the sector of areas covered by the base station 102. When interacting in a straight line 118, 124 communication transmitting antennas, base station 102 can use the beam to improve the signal-to-noise straight lines 119 and 124 communication for mobile devices, 116 and 122. Also, while the base station 102 uses the beam to transfer to a mobile device 116 and 122, dispersed by the associate zone, mobile devices in neighboring cells can be less interference than the base station that is broadcasting through one antenna for all its mobile devices.

Base station 102 (and/or each sector base station 102) can apply one or several technologies multiple access (for example, CDMA, TDMA, FDMA, OFDMA, ...). For example, the base station 102 can use a particular technology for interaction with mobile devices (for example, mobile devices, 116 and 122) in the appropriate bandwidth. In addition, if the base station 102 is used more than one technology, each technology can be associated with the appropriate bandwidth. The technology described in this document may include the following: Global system for mobile communications (GSM), General packet radio service (GPRS), GSM evolution with increased transmission speed data (EDGE), Universal mobile telecommunications system (UMTS)networks, Broadband multiple access code division (W-CDMA), cdmaOne (IS-95, CDMA2000, Optimized development only data (EV-DO), ultra-wideband mobile communication (UMB), global interoperability for microwave access (WiMAX), MediaFLO, Digital multimedia broadcasting (DMB), Digital video broadcasting handheld (DVB-H), etc. You have to understand that the foregoing list of technologies is provided as an example and the claimed subject matter is not so limited; rather, almost any wireless technology is intended for inclusion in volume attached to this document claims.

Base station 102 may apply first bandwidth with the first technology. In addition, the base station 102 can pass a pilot signal, corresponding to the first technology, second bandwidth. In accordance with the illustration, the second bandwidths can be involved base station 102 and/or any other base station (not shown), which uses every second technology. In addition, the pilot-signal can indicate the presence of the first technology (for example, a mobile device that interfaces in the second technology). For example, the pilot-signal can use the bit(s) to transfer information about the presence of the first technology. Moreover, in the pilot signal can contain information such as SectorID sector, using the first technology, CarrierIndex indicating the bandwidth of the first frequency, etc.

In accordance with another example, a pilot signal may be a beacon (and/or sequence of beacons). The lighthouse can be OFDM symbol, where a large share of the energy is transmitted in one sub-carrier or several carriers (for example, a small number of subcarriers). Thus, the lighthouse provides a sharp peak, which can be seen mobile devices, at the same time, potentially causing data in narrow bandwidth (for example, the remaining portion of the bandwidth may not be affected by the lighthouse). Following this example, the first sector can communicate via CDMA first of bandwidth, and the second sector can communicate by means of OFDM, second bandwidth. Accordingly, the first sector may indicate the availability of CDMA in the first bandwidth (for example, for a mobile device (s), using OFDM second bandwidth) by passing the lighthouse OFDM (or sequence of beacons OFDM) in the second bandwidth.

The considered invention can combine a number of transmit antennas in some amount of virtual antennas (for example, also called group, antennas, group transmitting antennas, etc. to allow inherited user equipment to use all quantity of transmitting antennas. In particular, inherited custom hardware may be able to use only up to four (4) entrances transmitting antennas (for example, created inputs antennas for the group UE). In wireless systems that use four or more transmitting antennas, inherited custom hardware can't use more than four entrances transmitting antennas. The considered invention can be grouped four or more transmitting antennas in virtual antenna by using, for example, a linear combination (for example, a linear combination of physical antennas, etc.) and use a virtual antennas as inputs transmitting antennas, which can use the inherited custom hardware, consequently allowing the inherited user equipment to apply more than four transmitting antennas. In other words, virtual antennas can be created so that inherited custom hardware could apply additional transmitting antenna (for example, more than four transmitting antennas). The considered invention can optionally pass a reference signals for transmitting antenna and/or delays related to a linear combination, modern user equipment (for example, user equipment, compatible with four or more antennas). On the basis of such transferred reference signals and delays modern user equipment can identify each transmitting antenna of each of the group established transmitting antennas.

The device is 200 communication can be the base station (for example, improved Site B, Site B, etc.) or the parts of the network or its part, a mobile device or its part, or virtually any communications device that receives data transmitted in the wireless environment.

In other words, the linear combination applies to all transmitting antennas in each group, where the linear combination can convert separation of transmission in frequency diversity for each of two or more groups. You have to consider that can use any appropriate linear combination, for example, but not only, the breakdown of cyclic delay (CDD). We must note that the linear combination may depend on the frequency.

The device is 200 communication may include module 206 reference signals, which can send and/or accept pilots (for example, the control signals) and/or delay used in linear combination.

In other words, the module 206 reference signals can decode or delete pre-coding of reference signals from grouped antenna to identify each antenna in each group.

Multiple transmit antennas can also be used to increase speed of data transmission. In MIMO systems with Nt transmitting and Nr reception antenna throughput increases linearly with min(Nt,Nr.

The breakdown of cyclic delay (CDD) is a scheme to convert explode transmission in frequency diversity in OFDM systems. Schema CDD contain the transmission of one and the same signal at different antennas with different delays. The following example shows how CDD converts separation of transmission in frequency diversity. Consider the case where channels from two transmitting antennas are H1(f) = H1 and H2(f) = H2, i.e. channels are not polling frequency. As delay corresponds to multiplication by a linear phase change in the frequency domain, the effective implementation of the canal after CDD proportional H1 + ejfD H2, where D is proportional to the delay made on the 2nd antenna. So schemes CDD increase the selectivity of frequency characteristics of the channel. If a signal is sent to two OFDM subcarriers, which are widely separated from each other, that is separating the two.

LTE version 8 supports 1, 2 or 4 input transmitting antennas. The number of inputs transmitting antennas can be declared through PBCH. Reference signal (RS) may be sent from each antenna input, which is used for evaluation purposes channel.

Advanced LTE can have more transmitting antennas at the base station (for example, 8, more than 8 etc.). Because of the inherited UE can only support 4 input transmit antennas, inherited UE through PBCH declares fewer inputs transmitting antennas, than is available. Let "declared inputs antennas" refer to the antenna inputs, announced inherited UE, and let all inputs antennas apply to all inputs of antennas available in the system. New UE can be informed about all available input of the antenna by means of a new mechanism (discussed below).

One method for legacy support, UE in such a system would be displaying one of the transmitting antenna one antenna input. It has recorded a transmitting antennas that can be used for transmission, controlled inherited UE, and may allow the use of all antennas only for transfers of controlled new UE. However, in this method, passing the transfer for inherited UE limited number of announced inputs antennas. The considered invention sends signals that are controlled inherited UE that allows inherited UE to obtain the decomposition of the transfer, which is more than the number declared inputs and antenna that requires no changes in the method, which is inherited UE process the received signal.

The considered invention can give possibility to group N group transmitting antennas available in the system, where N is the number of announced inputs antennas. We must note that the number of antennas in different groups could be different (for example, one group has two antennas, and the group has two three antennas, etc.) and antenna could belong to more than one group. In each such group scheme CDD can be used to convert explode transmission in frequency diversity. You have to consider that can use any suitable linear or nonlinear combination and CDD is just one example. In the receiver, all antennas in the group can act as one input of the transmitting antenna, and processing on the receiver does not change until you made on different antennas delay is not too large. For example, consider the case with 8 transmitting antennas, where 4 input transmitting antennas are declared inherited UE. Antenna 1 and 2 can be grouped in group 1, Antena 3 and 4 in group 2, antenna 5 and 6 in group 3 and antenna 7 and 8 in group 4. All antennas in the group N would work as a virtual antenna for UE by transmitting a signal corresponding announced antenna N using CDD. For example, this could be done by transmitting a signal as is on the first antenna in the group and by transmitting a signal, detained element of the signal onto a second antenna in the group.

Some channels management in LTE version 8 type PCFICH, PHICH and PDCCH extended frequency, and therefore the use of this scheme helps increase productivity inherited UE. For example, for PCFICH, PHICH and PDCCH inherited in UE instead of passing on 4 transmitting antennas can be passed on 4 virtual antennas, as is done for reference signal (RS) in the previous example.

To use this diversity during data transfer, the scheduler could plan UE resources PDSCH, distributed by frequency. PDSCH can be transmitted using the same scheme virtual antennas as RS, in order to benefit from this additional explode. In the case of transmission PDSCH with its own dedicated RS similar scheme virtual antennas can be used for a dedicated RS and the corresponding data in PDSCH. Virtual antenna used in this case to transmit data could differ from those for General RS.

The proposed technique virtual antennas can be used for both inherited and new UE, for example, for the control signal. Be aware that inherited UE can be UE, which is compatible with four or less transmitting antennas, and the new UE UE is that is compatible with four or more transmitting antennas. On the other hand, the technique of virtual antennas can be used for legacy UE, whereas for transmission PHICH, PDCCH and PDSCH to new UE, you can use another way to get improved separation of transmission, as they may have more pilot-signals and can appreciate the channel from different antennas.

To get higher data transfer speeds that are possible with all of the available inputs antennas, new UE must be able to assess the channel corresponding to all of the available inputs antennas, and report the quality of the channel (CQI, PMI, RI, CDI, etc.). New control signals can go for all inputs antennas that you want to use the new UE, in addition to a reference signal, already passed for inherited UE. On the other hand, new control signals can be designed so that they can be used with legacy RS for channel estimation of all transmitting antennas with the purpose of feedback and measurement. Reference signals can be subjected to removal of the pre-coding and can provide directions, not overlapped legacy RS. Also they can pre-encoded and provide directions pre-encoded channel is not given a legacy RS.

For example, consider the same example as above, where 8 transmitting antennas are grouped in 4 groups, and group 1 matches antennas 1 and 2, group 2 contains antenna 3, 4 and so on. Let hi(t) for i= 1 to 8, t denotes the time) represents the channel corresponding to the i-th of the transmitting antenna. Thanks to the scheme CDD, where the transmitted signal from one of the antennas is delayed by one member of a signal, for UE effective antenna gain on General RS is equal h1(t)+h2(t-Tc), the relevant RS in group 1, h3(t)+H1(t-Tc), the relevant group 2, and so on. Tc is the duration of elementary parcels.

Four new set of pilot signals can be transferred so that the effective gain channel-set to 1 pilot-signals equal h1(t)-h2(t-Tc), - set to 2 pilot-signals equal h3(t)-H1(t-Tc) and so on. This could be done by passing X(t) from one antenna and-X(t-Tc) of the following antennas. Therefore, we can obtain estimates hi(t), using the General RS and new pilots. In this specific example of a General RS assesses h2i-1(t)+h2i(t-Tc), whereas the new pilots evaluate h2i-1(t)-h2i(t-Tc). The sum and difference of these assessments, scaled and shifted accordingly, provide estimates h2i-1(t) and h2i(t).

The considered invention provides a schema to support the reference signal for additional 4 antennas. May be provided orthogonal multiplexing reference signals for different inputs antennas with different time shifts. For example, RS antenna 1 and 5 are sent to the resource RS for antenna 1. RS antenna 5 is delayed for a few elementary durations, for example CP/2 elementary parcels. In this case, the reference signal multiple antennas will be transmitted on the same frequency-temporal resources. The transmitted signal, corresponding to each antenna will have different sawtooth phases in frequency. Reference signal for all the antennas are multiplexed in one and the same set of resources, will differ only dependent on the frequency phase shift.

For legacy UE multiple antennas that use the same frequency-time resources for RS, would appear as one virtual antenna, and if their signals are sent similarly, they will not be affected. If the spread of delays channel from the antenna in a group known as the small (for example, part of cyclic prefix), then the new UE will be able to evaluate the channels from different antennas in the band of the received signal, corresponding RS this group.

UE LTE-A can use the specific information about multiplexing reference signals and sawtooth changes phase to assess the information channel for all antennas. This information can be static, and a pre-configured or can be adaptive and configurable. UE LTE-A will be informed about this information with the help of some mechanisms, such as the new block system information (SIB), sent by the General channels.

According to figure 4, approximate 400 system of wireless communication can organize two or more transmitting antennas. The 400 system is used for illustrative purposes and should not restrict the considered invention. For example, 400 system can use any appropriate number of transmit antennas, any appropriate number of groups for transmitting antenna and any appropriate number of transmit antennas in each group. The 400 system can include eight transmitting antennas (for example, the transmitting antenna 1 transmitting antenna 2, transmitting antenna 3, transmitting antenna 4, transmitting antenna 5, transmitting antenna 6, transmitting antenna 7 and transmitting antenna 8), which can be arranged in four groups, such as group 1 402, group 2 404, group 3 406 and group 4 408.

On the basis of the grouping transmitting antennas each group transmitting antennas can apply the technique of linear combinations (for example, CDD, etc.) to convert explode transmission in frequency diversity for each of two or more groups. Thus, inherited UE 410 can identify each group transmitting antennas (for example, group 1 402, group 2 404, group 3 406 and group 4 408). This allows the application of each of the transmitting antenna, regardless of whether inherited UE 410 number of transmit antennas less than four. In other words, inherited custom hardware 410 detects four transmitting antennas based on four groups. Custom hardware 412 (for example, modern user equipment, custom hardware that is compatible for use four or more transmitting antennas) can optionally use each of the transmitting antennas regardless groups transmitting antennas. Custom hardware 412 may take the delay is related to a linear combination and reference signals for groups transmitting antennas and/or each of the transmitting antenna. On the basis of such adopted delay and/or reference signals custom hardware 412 can decode or delete pre-coding and discover each transmitting antenna, in this case, all eight (8) transmitting antennas.

In accordance with the peculiarity, transmitting antennas available in the system wireless, grouped in N groups, where N is the number of announced antennas. In accordance with particularity, the number of antennas in different groups may be different. Moreover, each of the N group uses the breakdown of cyclic delay to convert explode transmission in frequency diversity. In the receiver, for example UE, all antennas in the group act as one transmit antenna, and processing on the receiver does not change until you made on different antennas delay is not too large. For example, one feature is implemented 8 transmitting antennas, and 4 transmitting antennas are declared inherited UE. Antenna 1 and 2 are grouped in group 1, Antena 3 and 4 are grouped in group 2, antenna 5 and 6 are grouped in group 3 and antenna 7 and 8 are grouped in group 4. All antennas in the group N would work as a virtual antenna for UE by transmitting a signal corresponding announced antenna N using CDD. For example, in one of the peculiarities of the signal is passed as-is on the first antenna in the group, and the signal is transferred detainees to an element of the signal on the second antenna in the group.

It should be noted that some of the control channels in LTE version 8, of the type of Physical channel indicator format control (PCFICH), Physical channel display H-ARQ (PHICH) and Physical control channel downlink (PDCCH), extended frequency, and therefore the use described in this document features helps increase productivity inherited UE. For example, for PCFICH, PHICH and PDCCH inherited in UE instead of passing on 4 transmitting antenna is transmitting on 4 virtual antennas, as for the reference signal RS in the previous example. Thus, it is necessary to consider that the present invention may pass at least one of the RS, PCFICH, PHICH, PDCCH and PDSCH to the group UE using inputs antennas, reported back to the group UE.

In accordance with the feature to use the explode send data, the scheduler can assign UE resources PDSCH, distributed by frequency. PDSCH can be transmitted using the same scheme virtual antennas as RS, in order to benefit from this additional explode. In the case of transmission PDSCH with their own dedicated RS similar scheme virtual antennas can be used for a dedicated RS and the corresponding data in PDSCH. In accordance with the peculiarity of the scheme of virtual antennas in this case would be different from that for total RS.

In accordance with one or more aspects of the proposed method of virtual antennas can be used for both inherited and new UE. On the other hand, the method of virtual antennas can be used for legacy UE, whereas for transmission PHICH, PDCCH and PDSCH to modern UE could use another way to get improved separation of transmission, because modern UE can have more pilot-signals and can appreciate the channel from different antennas.

To get higher data transfer speeds that are possible with all available transmitting antennas for demodulation modern data UE must be able to evaluate pre-encrypted channel, corresponding to all the transmitted radiation. In one particular the new pilots (selected control signals) can be transmitted in the field PDSCH to assist in the evaluation of pre-encoded channel. New pilots can pre-coded using the same rays that were used for data transmission, and can provide an estimate of pre-encoded channel all rays. On the other hand, is implemented by the Reference signal is sent for legacy devices, and new pilots (selected control signals) can be designed so that they can be used with legacy RS for channel estimation for demodulation data. For example, the control signals can not be pre-coding or use a constant pre-coding regardless of what is used for data, and can represent areas that are not covered legacy RS. Pre-encrypted channel for demodulation of data can then be evaluated using the legacy RS, as well as the new pilot-signals and using transformations between the rays of transmission and directions legacy RS and new pilot-signals. In other aspects the reference signal can also pre-coded for specific UE and provide directions pre-encoded channel is not given a legacy RS.

Therefore, in accordance with some aspects, assessment channel for demodulation can be run using legacy RS and newly allocated RS envisaged for modern UE. New dedicated RS can provide information about the channel in the direction of the rays used (and with the operation of the preliminary encoding) when passed to the UE. In some aspects allocated RS can imagine the whole pre-encrypted channel, or, as an alternative, you may show that the pre-encoded channel presents legacy RS. Pre-encrypted channel can match the channel between UE and antennas in a solitary cell for operations MIMO of the highest order or between the UE and aerials of different hundred interacting in a network operations MIMO.

In accordance with some aspects of the management alarm downlink to the UE can provide some information about the matrix preliminary coding (or directions rays), used for passing to the UE. These directions rays can match rays, educated antennas one cell, equipped with multiple antennas (up to 8 for LTE-A), or rays, educated antennas from a few hundred (or sections)participating in joint transmission schemes affecting the UE. These joint schemes can exist in different forms, such as distributed beam or, alternatively, joint processing and signal processing.

In accordance with some aspect of information transmitted via the control signalling to UE, may belong to different types:

b) indicators matrix preliminary coding, appropriate directions pre-encoded channel presents legacy RS. In this case, the selected RS represents the direction of pre-encoded channel presents legacy RS. UE receives a score of only pre-encoded channel using the preliminary encoding that corresponds legacy RS and pre-encoded allocated RS;

C) the indicators for vectors of the preliminary encoding used by all (or some) cells involved in the cooperation scheme involving UE.

In scenarios where you use the frequency-dependent preliminary coding, you have several matrices preliminary encoding used for different parts of the strip, the managing alarm downlink may disclose some or all, of them.

Figure 5-6 illustrates the methodology related to the grouping transmitting antennas for legacy user equipment and the transmission of information about the delay for the UE. Although in order to simplify the explanation of the methodology are shown and described as a sequence of actions necessary to understand, that methodology is not limited to the procedure, because certain actions in accordance with one or a few types of exercise can be done in other orders, and/or together with other actions, unlike shown and described in this document. For example, specialists in a given field of technology will understand and take into account that in the alternative methodology could be represented as a sequence of interrelated conditions or events, for example, on the state diagram. In addition, not all illustrated the steps may be needed to implement the methodology in accordance with one or several variants of implementation.

Figure 5 illustrates the methodology 500, which provides optimization of the Extended system of long-term evolution (LTE (A). At the stage 502 can identify at least two groups UE. At the stage 504 may be signalled by a different number of antenna inputs, at least, two groups UE. At the stage 506 can be created inputs antennas that are appropriate to each group UE, each input of the antenna includes a subset of a certain amount of physical transmitting antennas, and the number of antenna inputs equal to the number of antenna inputs, signaled the same group UE.

Figure 6 illustrates the methodology 600, which ensures identification of many inputs antennas. At the stage 602 can be accepted information display, which involves at least one delay and linear combination used to transfer the reference signal, related to the many inputs antennas. At the stage 604 can be accepted reference signal, related to the inputs of the antennas. At the stage 606 can be decoded signal, related to the many, to identify each antenna input, and decoding uses the information display.

In addition, although not shown, the methodology 600 can optionally contain the use of the transferred reference signal for the inputs of the antennas in the first group, UE, at least for one measurement, feedback from the base station or method of demodulation and the use of the transferred reference signals for the inputs of the antennas in the second group UE for measurement and feedback with the base station.

Mobile device contains 700 receiver 702, receiving, for example, from the receiving antenna (not shown), the model performs actions on the received signal (for example, filters, strengthens, converts with decreasing frequency, etc.) and digitizes the converted signal for obtaining samples. The receiver 702 may contain demodulator 704, which can analyze the received symbols and submit them to the processor 706 for the assessment of the channel. Processor 706 can be a processor designed for the analysis of data received by the receiver 702, and/or compilation of information for the transfer transmitter 716, processor, which operates one or more components of the mobile device 700, and/or processor on the market, how to analyze the information, adopted by the receiver 702, generates information for transmission transmitter 716 and manages one or more components of the mobile device 700.

It is clear that described in this document data store (such as a storage device 708) can either be volatile storage device, or a nonvolatile memory, or may include both volatile and non-volatile storage device. As an illustration, but not limitation, a non-volatile storage device may include permanent memory (ROM), programmable ROM (PROM), electrically programmable ROM (EPROM), electrically erasable PROM (EEPROM) or flash memory. Volatile storage device may include random access memory (RAM), which acts as external cache memory. As an illustration, but not limitation, RAM is available in many forms, such as synchronous RAM (SRAM), dynamic RAM (DRAM), synchronous DRAM (SDRAM), SDRAM with twice the rate of exchange (DDR SDRAM), advanced SDRAM (ESDRAM), synchronous DRAM exchange channel (SLDRAM) and RAM with direct access from Rambus (DRRAM). Storage device 708 of those systems and methods designed to include (without being limited to) these and any other appropriate types of storage devices.

Processor 706 may additionally be functionally connected to the module 710 collection and/or module 712 reference signals. Module 710 collection can take delays, used techniques for linear combinations for each group, which includes a transmitting antenna. Module 710 collection can also take reference signals relevant to each group that you created transmitting antennas, each group includes at least one transmission antenna of a number of available transmitting antennas. Module 712 reference signals can attract the collected data (for example, delay and/or reference signals) to eliminate prior to encode or decode and identify each of the transmitting antenna included in each group. Thus, the module 710 reference signals may allow the identification of available transmitting antenna appointed created group.

Mobile device 700, also contains modulator 714 and transmitter 716 respectively modulate and transmit signals, such as signals to the base station, another mobile device, etc. Although depicted as separate from the processor 706, it is clear that the module 710 collection, module 712 reference signals, demodulator 704 and/or modulator 714 can be part of the processor 706 or multiple processors (not shown).

Fig is an illustration of the system 800, which provides better use of the transmitting antenna in the environment of wireless communication, which are described earlier. The system contains 800 base station 802 (for example, access point, ...) with receiver 810, which receives the signal (s) from one or more mobile devices 804 through many receiving antennas 806, and transmitter 824, which sends it to one or more mobile devices 804 through transmitting antenna 808. The receiver 810 can receive information from the receiving antennas 806 and functionally connected with the demodulator 812 that demodulates the newly received information. Demodulated characters are analyzed processor 814, which can be of the same processor, described above with respect to 7, and which is connected with the storage device 816, which stores information relevant to the evaluation of the level of the signal (for example, the pilot signal) and/or noise data to be sent or received from your mobile device (s) 804 (or another base station (not shown)), and/or any other pertinent information relevant to the implementation of various activities and functions set out in this document.

Processor 814 additionally connects with the module 818 groups and/or module 820 linear combinations. Module 818 group might identify the available transmitting antenna and organize available transmitting antennas in N groups, where N is a positive integer and is the number of announced antennas. Module 820 linear combinations can be applied to each antenna in the group method of linear combinations, for example, but not only, the breakdown of cyclic delay. In addition, although depicted as separate from the processor 814, you need to understand that the module 818 groups, module 820 linear combinations, demodulator 812 and/or modulator 822 can be part of the processor 814 or multiple processors (not shown).

Figure 9 shows a sample system 900 wireless communications. The system 900 wireless depicts one base station 910 and one mobile device 950 for short. However, we must take into account that the system of 900 can include more than one base station and/or more than one mobile device, where additional base stations and/or mobile devices can be basically the same as or different from the estimated base station 910 and mobile devices 950 described below. Besides, we need to take into account that the base station 910 and/or mobile device 950 can use system (figure 1-3 and 7, 8)methods/configuration (figure 4) and/or processes (figure 5, 6)described in this document to facilitate wireless communication between them.

On the base station 910 traffic data for a certain number of data streams available from the source 912 data processor 914 transmit (TX) data. According example, each thread data can be transmitted on the appropriate antenna. Processor 914 transmitted data formats, codes and punctuates the data flow of traffic based on specific encoding scheme is selected for the data stream to provide the coded data.

The coded data for each data stream can with pilot data using methods multiplexing orthogonal frequency division (OFDM). Additionally or alternatively, pilot symbols can be multiplexed frequency division (FDM), multiplex time division (TDM) or multiplexed code division (CDM). Pilot data are usually well-known pattern of data that is processed known and can be used on the mobile device 950 to assess the characteristics of the channel. Multiplexed pilot and the coded data for each data stream can be modulated (for example, character by character to transform itself) on the basis of a particular modulation schemes (for example, dip phase shift keying (BPSK), quadrature phase shift keying (QPSK), M-positional phase shift keying (M-PSK), M-point quadrature amplitude modulation (M-QAM), etc.)selected for the data stream to provide the characters modulation. The speed of transmission of data, coding and modulation for each data stream can be defined commands that are performed or provided by the processor 930.

Characters modulation for data streams can be provided to the processor 920 MIMO transmission, which can optionally handle characters modulation (for example, for OFDM). Processor 920 transfer MIMO then provides NT streams of characters modulation NT transmitters 922a-922t (TMTR). In different variants of implementation of the processor 920 transfer MIMO uses the weight of the beam shaping the character of the data stream and to antenna from which the character is sent.

Each transmitter 922 receives and processes the corresponding character stream to provide one or more analog signals and further processed (for example, amplifies, and filters converts with increasing frequency analog signals to provide a modulated signal suitable for transmission over MIMO channel. Next, NT modulated signals from transmitters 922a-922t transferred from NT antennas 924a-924t respectively.

On a mobile device 950 transferred modulated signals, NR antennas 952a-952r, and the signal from each antenna 952 provided the respective receiver 954a-954r (RCVR). Each receiver 954 processes (for example, filters, strengthens and converts with decreasing frequency) corresponding signal, digitizes the processed signal to provide samples and advanced processes sampling to provide the appropriate "adopted" a stream of characters.

Processor 960 received data can accept and process NR adopted streams of characters from NR receivers 954 based on specific processing method receiver to provide NT "found" streams of characters. Processor 960 received data can demodulate, correct alternation and decode each discovered a stream of characters to restore the data traffic flow data. The CPU 960 accept data complementary to the one that is executed by the processor 920 MIMO transmission and processor 914 transmitted data base station 910.

Processor 970 may periodically to determine the matrix preliminary encoding to use, as discussed above. Next 970 processor can compose a message back line, containing part of the index of the matrix and the value part of the grade.

Message reverse communication line can contain various types of information regarding line and/or received data flow. Message reverse lines of communication can be handled by the processor 938 transmitted data, which also receives traffic data for a certain number of data streams from 936 source of data to be modulated by modulator 980, process transmitters 954a-954r and passed back to the base station 910.

On the base station 910 modulated signals from mobile devices 950 accepted antennas 924, processed receivers 922, the demodulator 940 and processed by the processor 942 accept data to retrieve the message return line communications sent by a mobile device 950. Next processor 930 can process the extracted message to determine the matrix preliminary encoding to use for the determination of scales of beam.

You have to understand that described in this document options for implementation can be implemented in hardware, software, firmware, middleware, the microcode or in any combination.

For example, the system can accommodate 1000, at least partially, in the base station, mobile, etc. Need to understand that 1000 system is represented as including functional blocks, which can be functional blocks, which are functions that are implemented by the processor, software, or a combination thereof (for example, firmware).
