The technical field to which the invention relates

The following description generally relates to wireless communications, and more particularly to scheduling sub-bands and the ratio of the power loss of the power amplifier.

The level of technology

Wireless network systems have become common means by which most people around the world share information. Wireless communication devices have become smaller in size and more efficient to meet the needs of the consumer and increase portability and ease of use. Consumers have become dependent on wireless communications devices, such as telephones for cellular, personal digital assistants (PDAs), etc. that require reliable performance, extended coverage and increased functional the x capabilities.

Typically, wireless communication system, multiple access can simultaneously support communication for multiple wireless terminals or user devices. Each terminal communicates with one or more access points via transmissions on forward and reverse links. Direct link (or downward communication refers to the communication link from the access points to the terminal, and the reverse link (or upward communication refers to the communication link from the terminals to the access points.

Wireless systems can be multiple access systems that are capable of communication with multiple users by sharing available system resources (e.g., bandwidth and transmit power). Examples of such multiple access systems include a system of multiple access code division (CDMA)systems, multiple access with time division (TDMA)systems, multiple access frequency division (FDMA) system and multiple access orthogonal frequency division multiplexing (OFDMA).

Typically, each access point serves the terminals located within a particular service area, referred to as a sector. The sector that supports a specific terminal, called on the servicing sector. Other sectors that do not support a specific terminal, referred to as non-serving sectors. Terminals within a sector can be allocated specific resources to enable simultaneous support of multiple terminals. However, transmission from terminals in neighbor sectors are not coordinated. Therefore, transmission from the terminals on the sector boundaries can lead to interference and poor performance of the terminal.

In the following description, for clarification, describes numerous specific details to provide a complete understanding of one or more embodiments. However, you can clearly see that such an option(s) can be implemented without these specific details. In other cases, known structures and devices are depicted in the form of a structural schema in order to facilitate describing one or more embodiments.

As used in this application, the terms "component", "module", "system", etc. refers to related to related to the use of computer object, or hardware, firmware, a combination of hardware and software, software, or design software. For example, a component may be, but not limited to, a process running on clicks the processing device (CPU) processing device, an object, an executable, a thread of execution, a program and/or computer.

In addition, these components can execute from various computer-readable media storing on different data structures. Components can communicate via local and/or remote processes such as in accordance with a signal containing one or more data packets (e.g., data from one component interacting with another component in a local system, distributed system and/or network such as the Internet with other systems via the signal).

In addition, various embodiments of described herein with reference to a mobile device. The mobile device may also be called a system, subscriber unit, subscriber station, mobile station, mobile device, remote station, remote terminal, access terminal, user terminal, t is renala, the wireless communication device, user, reseller, user device, or user equipment (ON). The mobile device may be a telephone, cellular, wireless phone, phone with support for session initiation Protocol (SIP), station wireless local loop (WLL), personal digital assistants (PDA), a portable device with wireless capabilities, computing device or other processing device connected to a wireless modem. Moreover, various embodiments of described herein with respect to the base station. The base station can be used for communication with the mobile device(s) and may also be referred to as an access point, node B, or using some other terminology.

Moreover, various aspects or features of the invention described herein may be implemented in the form of a method, device, or product using standard programming and/or engineering technologies. The term "product"as used herein, involves the inclusion of a computer program accessible from any computer-readable device, carrier or media. For example, machine-readable medium may include, but is not limited to ivalsa this, magnetic storage devices (e.g. hard disk, floppy disk, magnetic card, etc), optical disks (such as compact disc (CD), digital versatile disk (DVD), etc.), smart cards and memory devices group overwriting (e.g., EPROM, charge card for the camera, the drive key etc). Additionally, various storage media described herein may represent one or more devices and/or other machine readable mediums for storing information. The term "machine-readable medium" can include, without being limited to this, wireless channels and various other media with the capability of storing, receiving and/or transfer instructions(s) and/or data.

The techniques described herein can be used for various wireless communication systems such as communication systems, multiple access systems, broadcasting, wireless local area networks (BLS), etc. the Terms "system" and "network" are often used interchangeably. System with multiple access can use a multiple access scheme such as CDMA, TDMA, FDMA, orthogonal FDMA (OFDMA), FDMA with single-carrier (SC-FDMA), etc. System with multiple access can also use a combination of multiple access schemes, such as one or more of the multiple schemes is on access for downlink and one or more multiple access schemes for uplink communication.

OFDMA uses multiplexing orthogonal frequency division (OFDM), which is a multiplexing scheme with many carriers. SC-FDMA can use a limited multiplexing frequency division (LFDM), Alternating FDM (IFDM), Advanced FDM (EFDM), etc. which are different multiplexing schemes with a single carrier, which collectively are called FDM with single-carrier (SC-FDM). OFDM and SC-FDM share the bandwidth of the system into multiple (K) orthogonal subcarriers, which are usually also referred to as tones, Bina etc. Each subcarriers may be modulated with data. Typically, the modulation symbols are transmitted in the frequency domain using OFDM, and in the time domain with SC-FDM. LFDM transmits data in a continuous subcarriers IFDM transmits the data to the subcarriers that are distributed across the bandwidth of the system, and EFDM transmits data in groups of contiguous subcarriers.

OFDM has several desirable characteristics, including the ability to combat the effects of multipath propagation, which is dominated by the terrestrial communication system. However, the major disadvantage of OFDM is the high peak-to-average power (PAPR) of the OFDM waveform, i.e. the ratio of peak power to average power for OFDM waveform can be is high. High PAPR is a consequence of the possible addition of phase (or coherent combining) all subcarriers, when they independently modulated with data. High PAPR for OFDM waveform is undesirable and can degrade performance. For example, large peaks in the waveform, OFDM can cause the amplifier to work in too non-linear region or perhaps truncation, which can then lead to cross distortion and other induced noise, which can degrade the signal. To avoid non-linearity, the power amplifier has to work with a coefficient of loss of power to the average power level which is lower than the peak power level. When the power amplifier with a coefficient of power loss in peak power, when the ratio of the power loss can be in the range of 4 to 7 dB, the amplifier can handle large peaks in the waveform, not generating excessive distortion.

SC-FDM (for example, LFDM) has some desirable characteristics such as resistance to the effects of multipath propagation, similar to OFDM. While the SC-FDM does not have a high PAPR, since the modulation symbols are transmitted in the time domain with SC-FDM. PAPR waveform of the SC-FDM signal is determined points in the signal constellation, selected used for the I (for example, M-PSK (M-ary phase shift keying), M-QAM (M-ary quadrature amplitude modulation), and so on). However, the modulation symbols of the time domain in the SC-FDM tend to intersymbol interference due to the uneven frequency response of the communication channel. To mitigate the harmful effects of intersymbol interference on the received symbols can be cleared.

According to the features of the invention, OFDM and SC-FDM (for example, LFDM) can be used for transmission over a given communication line (for example, upward communication). As a rule, the effectiveness of communication for OFDM waveform exceeds the efficiency due to the waveform of the SC-FDM. Higher efficiency due OFDM is balanced by the large coefficient of power loss power amplifier for OFDM, than for the SC-FDM. Thus, SC-FDM has before OFDM advantage of the low PAPR. For high signal to noise ratio (SNR), strengthening the channel OFDM can override the advantage of SC-FDM in PAPR. Using both OFDM and SC-FDM system can benefit from greater efficiency in OFDM communication for scenarios with high SNR, as well as from the advantages of SC-FDM for PAPR for scenarios with low SNR.

In General, any scheme of SC-FDM can be used in conjunction with OFDM. While OFDM and SC-FDM can be shared for uplink communication or downlink or uplink communication, nicholasa line. To simplify, a large part of the following description refers to the sharing of OFDM and LFDM on the ascending line.

Figure 1 shows a structural diagram of a system 100 that provides dynamic loss coefficient power amplifier. The system 100 includes at least one base station 102 and at least one mobile device 104 serviced by sector base station 102. The term sector can refer to a base station and/or area covered by the base station, depending on the context. For simplicity, shows a single base station and mobile device. However, the system 100 may include multiple base stations and mobile devices. Base station 102 can explicitly control the scheduling of sub-bands, mobile device 104. The planning sub-bands allows to realize the gains from multi-user diversity by planning mobile adaptive on limited areas of the frequency range of the system according to channel conditions, among other things. The size of the subrange must provide sufficient frequency diversity, in order to prevent the deterioration of performance for fast-moving mobile devices, as well as the deterioration of the throughput of the sector with equally PLA is investing service. In addition, a small sub-bands can lead to loss of efficiency of the provision of free channels because of the planning sub-bands (for example, the smaller sub-bands, the smaller the variety of mobile devices for each subband).

Figure 2 shows an illustrative tree channel with local hopping spread. The mobile device is scheduled for a certain sub-band and receiving the appointment of a bandwidth less than the full range, performs a jump within the sub-band to maximize frequency diversity of the channel. In figure 2, each base node is displayed on the 16 adjacent tones in frequency. A set of eight core nodes is displayed on the sub-band, which consists of 128 contiguous tones. Within the sub-bands, groups of 16 tones (i.e. basic nodes) make the leap pseudo-random. In addition to planning mode of the sub-bands may be useful mode explode. The sector can mainly to serve the fast-moving users (for example, the sector covers road). In such cases, the base nodes of the channel can abruptly change within the entire frequency range.

According to figure 1, usually in order to support the planning of sub-bands, the mobile device has the accommodat who manage information feedback about the properties of a channel of direct communication line, related to different sub-bands. The amount of feedback information must balance the efficiency gains of a straight line because of the planning sub-bands depending on unproductive losses in the return line caused by the feedback channels. A proper balance depends on the load on the control channel of the reverse link, which, in addition to feedback information about planning sub-ranges, tolerates other control information of the reverse link.

According to one aspect of disclosure of the subject invention, the mobile device 104 sends the information about the maximum power value to the base station 102. The base station 102 uses the received information about the marginal value of capacity to plan the mobile device 104 to the sub-range. Information about the maximum power value may include information related to the magnitude of the power amplifier or characteristics of the mobile device 104. Moreover, information about the maximum power value may include various power levels that can be used in various types of assignments. For example, mobile device 104 may have one power level in the inner sub-band and at the same time to have a different power level in the regional poddiapazona mobile device 104 may report the maximum power, which it can achieve, if his appointment covers the entire bandwidth, the inner sub-band or a single base node. In addition, information may convey the impact of the limiting conditions due to interference, if any. In addition, information about the maximum power value may include a location within a given sector or cell and/or location information regarding more than one sector or cell. Additionally, information about the maximum power value transmitted from the mobile device 104 may include setting the power ratio carrier to interference experienced by the mobile device 104. While Figure 1 depicts the mobile device 104, transmitting information about the maximum power value to the base station 102, it is necessary to take into account that the base station 102 may display such information on the basis of their lines of communication and interaction with the mobile device 104. For example, base station 102 may estimate the received power level or accept feedback, to conclude any limiting condition on power imposed on the mobile device 104.

The base station 102 uses the information about the marginal value of capacity to plan the mobile device 104 at subrange is, available to the system 100. In accordance with one aspect of the disclosure of the subject invention, the base station 102 is planning a limited capacity of mobile devices mainly on the domestic sub-bands. Mobile device without capacity constraints are planned for the remaining range. When selecting sub-bands, the base station 102 takes into account the power limit of the mobile device 104 in addition to the selectivity of the channels on the subranges. Base station 102 transmits the scheduling information to the mobile device 104, indicating the sub-band, which is activated by the mobile device 104.

Figure 3 shows a system 300 wireless communication in accordance with various implementation presented in this document. The system 300 includes a base station 302 that can include multiple antenna groups. For example, one antenna group may include antennas 304 and 306, another group may contain antennas 308 and 310, and an additional group may include antennas 312 and 314. For each antenna group are depicted two antennas; however, for each group, there may be more or fewer antennas. Base station 302 can further include the transmit path and the receive path, each of which can, in turn, contain many components, SV is related to the transmission and reception of signals (for example, machining device for modulation, multiplexing device, a demodulation device, the device demuxing, antennas and so on)that will be fully clear to the person skilled in the technical field.

The base station 302 may communicate with one or more mobile devices, such as mobile device 316 and the mobile device 322; however, we must take into account that base station 302 can communicate with virtually any number of mobile devices such as mobile devices 316 and 322. The mobile device 316 and 322 can be, for example, telephones for cellular, smart phones, compact computers, handheld communication devices, handheld computing devices, satellite radio, global positioning systems, PDAs, and/or any other suitable device for establishing a connection through the system 300 wireless. As shown, the mobile device 316 communicates with antennas 312 and 314, and the antenna 312 and 314 transmit information to the mobile device 316 in a straight line 318 connection and receive information from mobile device 316 through a return line 320 connection. However, mobile device 322 communicates with antennas 304 and 306, and the antenna 304 and 306 transmit information n the mobile device 322 in a straight line 324 communication and receive information from mobile device 322 through a return line 326 connection. For example, in the duplex frequency division (FDD), a straight line 318 connection may use a frequency band different from that used reverse line 320 connection, and a straight line 324 connection may employ a frequency range that is different from that used reverse line 326 connection. Additionally, in the system of duplex time division (TDD), a straight line 318 connection and return line 320 connection can use a common frequency band, and a straight line 324 communication and return line 326 connection can use a common frequency range.

Each group of antennas and/or region, to establish the relationship in which they are intended, may be referred to as a sector of the base station 302. For example, the antenna group can be used for communication with mobile devices in a sector of the areas covered by base station 302. When connecting straight lines 318 and 324 communication transmitting antennas of the base station 302 can use the formation of the pattern, in order to improve the signal-to-noise straight lines 318 and 324 connection for mobile devices 316 and 322. In addition, while the base station 302 uses the formation of a pattern for transmission to the mobile device 316 and 322, randomly dispersed in the appropriate area of service is for, mobile devices in neighboring cells can be subject to less interference as compared with the base station performing transmission through a single antenna to all its mobile devices. According to the example, the system 300 may be a communication system with multiple inputs and multiple outputs (MIMO). Additionally, the system 300 may use a technology duplex transmission of any type to separate communication channels (for example, a straight line, the return line ...), such as FDD, TDD and so on

Figure 4 shows a system 300 wireless, which makes the planning of sub-bands, taking into account the capacity limits. The system 400 includes a base station 402, which establishes communication with the mobile device 404 (and/or any number of different mobile devices (not shown)). The base station 402 may transmit information to the mobile device 404 through the channel of direct communication line; additionally, base station 402 can receive information from the mobile device 404 through the channel of the reverse link. Moreover, the system 400 can be a MIMO system.

The system 400 uses the technology of repression, which weakens the effect of nonlinear distortion on the border of the mask. Nonlinear distortion refers to the phenomenon of non-linear dependencies between input and output, for example, electronically the first device. According to one feature of the invention, consider the nonlinear dependence is related to the power amplifier.

Mobile device 404 may include an indicator 410 of the limit value of the power device 412 valuation ratio of the power loss and amplifier 414 power. Indicator 410 limit power value of the mobile device 404 determines the rate of capacity restrictions, which reflects the restrictive terms of power imposed on the mobile device 404. Mobile device 404 transmits the rate-limiting power to the base station 402. You need to take into account that the base station 402 may display such information on the basis of their lines of communication and interaction with the mobile device 404. For example, base station 402 can evaluate the received power level or accept feedback, to determine any limiting condition on power imposed on the mobile device 404. The indicator of the power limitations may include information related to the magnitude of the power amplifier or characteristics of the mobile device 404. In addition, the indicator can convey the impact of the limiting conditions due to interference, if any. In addition, information about the maximum power value may contain the location before the crystals of a given sector or cell and/or location information regarding more than one sector or cell. Additionally, information about the maximum power value transmitted from the mobile device 404 may include setting the power ratio carrier to interference experienced by the mobile device 404.

The base station 402 receives the indicator of the power limitations of mobile devices 404 and uses this metric to determine planning sub-bands. The base station 402 includes device 406 choice of sub-bands and the device 408 planning sub-bands. The device 406 selector selects the sub-bands sub-band, whereas the indicator of the power limitations of the mobile device 404 and the selectivity of the channels on the subranges. Device 408 planning subranges plans mobile device 404 and other mobile devices served by base station 402. In accordance with an aspect of the disclosure the object of the invention, the device 408 planning subranges plans mobile devices with limited power mainly on the domestic sub-bands. For example, users with high quality of service (QoS) limited value of the power amplifier at the border sector or cell can be planned on the inner sub-bands. The most active users on the border sector or cell, which are not limited by control of the population interference (for example, the transmit power of the user, a limited bit busy signal from adjacent sectors), can also be planned on the inner sub-bands of spectrum allocation. Additionally, the device 408 planning subranges plans mobile device without capacity constraints on the remaining spectrum. For example, the most active users on the border sector or cell, which are limited by controlling the interference (for example, the transmit power of the user is not limited bit busy signal from adjacent sectors)can be planned for the remaining part of the spectrum after planning users with limited capacity. In addition, users with large quantities of power amplifiers can be planned for the remainder of the allocated spectrum, as users with high ratios of carrier power to interference (C/I). Users with high C/I can extract only a small benefit from additional increase in C/I, which may be the result of planning on the middle of the selected range.

Internal sub-bands are the bands far from the borders of spectrum allocation or full bandwidth. Out-of-band radiation is radiation at the frequency or frequencies immediately outside the band of frequencies in the modulation process is and. The level of out-of-band radiation depends on the total bandwidth covered by the assignment, and the proximity of this area to the border of the distribution range, or the maximum bandwidth of the system. Generally, the larger the area of destination (i.e. the broad purpose), the greater the level of out-of-band radiation. In addition, the purpose of farther from the border leads to a lower level of out-of-band radiation. The level of out-of-band radiation can be measured as a function of the total power in the band of 1 MHz, adjacent to the distribution channels. According to the example, the combined capacity of all transmissions in the band 1 MHz must not exceed -13 dBm. Additionally, for a typical average transmit power 23 dBm spectral mask requires attenuation of approximately 30 dB in the adjacent band 1 MHz.

The boundary of the mask is determined as the difference between the permissible exposure level and the actual level of radiation. Border spectral mask Lmaskcan be represented as follows:

In accordance with this illustration, Pmaskis the limit mask. According to the example, Pmaskshould not exceed -13 dBm. PTXis the total transmitted power. The value ofreflects the power spectral density at the output of adding to the El power. The value ofis adjacent to the distribution channels band 1 MHz. A positive value indicates penetration of the actual radiation level at the limits. A negative value indicates that the permissible exposure level is exceeded.

Users have an acceptable threshold in the regional sub-range as in the OFDMA system, and LFDMA system, if users have a large coefficient of power loss or asking a small assignment. In the situation of users who use a small coefficient of power loss, OFDMA users receive negative threshold value at medium-and large assignments, while LFDMA users receive a small positive threshold value with the average function. For users, scheduled for the middle or inner subrange, users receive a positive threshold value with a low coefficient of power loss as in the OFDMA system, and LFDMA systems. When scheduling users on average subrange and OFDMA and LFDMA have sufficient border spectral mask even when the ratio of the power loss 0 dB, which suggests that both can operate at such a low coefficient of power loss. Accordingly, the lack of PAPR for OFDMA does not affect the efficiency of power is compared to LFDMA, if users are planned far from the border of the distribution range. The base station 402 transmits the assignment and scheduling information to the mobile device 404. Mobile device 404 includes device 412 evaluation of the coefficient of loss of power to establish loss coefficient power amplifier 414 power on the basis of information about planning. In a situation where information about the plan adopted by the mobile device 404, requires medium or large appointment scheduled in the regional sub-band device 412 valuation ratio of the power loss sets a large coefficient of power loss. Usually the ratio of the power loss should be approximately 2 dB more for OFDMA systems than for LFDMA systems to support equal to the threshold value for the spectral mask. However, if the device 408 planning sub-bands prescribes the planning of the mobile device on the middle or inner sub-band device 412 valuation ratio of the power loss sets the low coefficient of power loss, which is sufficient to provide a reasonable benchmark for the spectral mask. According to the aspect of the disclosure the object of the invention, the device 412 valuation ratio of the power loss configures the amplifier 414 power for the application is placed lower coefficient of power loss (i.e. higher transmit power)when the mobile device 404 is planned for the inner sub-band. When planning on a regional sub-band amplifier 414 power works with a higher ratio of power loss (i.e. with lower transmit power). In addition, you may take into account the width of the destination. For example, when a mobile device 404 is planned only on 16 carries (i.e. one base node), out-of-band radiation is low, because the purpose of continuously and overlaps the narrow part of the full bandwidth. In this situation, may be permitted low power loss and high power transmission.

Figure 5 illustrates a system 500 wireless communication in accordance with various aspects of the invention presented in this document. The system 500 may contain one or more dots 502 access that receive, transmit, repeat, etc. signals in the wireless channel to each other and/or one or more terminal 404. Each base station 502 can contain multiple transmit paths and receive paths, for example one for each of the transmitting and receiving antenna, each of which can, in turn, contain a number of components associated with transmission and reception of signals (for example, processing device modules and, the multiplexing device, a demodulation device, the device demuxing, antennas etc). The terminal 504 can be, for example, telephones for cellular, smart phones, compact computers, handheld communication devices, handheld computing devices, satellite radio, global positioning systems, PDAs, and/or any other suitable device for establishing a connection through the system 500 wireless.

As shown in figure 5, each access point provides the communication area for a particular geographical region 506. The term "cell" can refer to an access point and/or its service area depending on the context. To improve system throughput, the service area point dost the PA may be divided into multiple smaller areas (e.g., three smaller region 508A, 508B and 508C). Each smaller area is served by a respective base transceiver subsystem (BTS). The term "sector" can refer to a BTS and/or its service area depending on the context.

11 shows an illustrative system is it 1100 wireless. The system 1100 wireless for brevity depicts one base station 1110 and one mobile device 1150. However, we must take into account that the system 1100 may include more than one base station and/or more than one mobile device, and additional base stations and/or mobile devices can be substantially similar or different from the illustrative base station 1110 and mobile devices 1150, described below. In addition, you need to take into account that the base station 1110 and/or mobile device 1150 can use system (figure 1, 3-5 and 9-10) and/or methods (Fig.6-8)described herein to facilitate wireless communication between them.

At the base station 1110, the data traffic for multiple data streams is provided from a source 1112 data on the device 1114 processing data. According to the example, each data stream can be transmitted via a corresponding antenna. The device 1114 processing data formats, encodes, and punctuates the flow of data traffic based on a particular coding scheme selected for that data stream to provide coded data.

The coded data for each data stream can multiplicious with the data of the pilot signal using the methods of multiplexers is of orthogonal frequency division (OFDM). Additionally or alternatively, the pilot symbols can multiplicious frequency division (FDM), multiplicious time division (TDM) or multiplicious code division (CDM). Data pilot signal, as a rule, are known for the combination of data that is processed in a known manner and can be used on a mobile device 1150 to assess the characteristics of the channel. Multiplexion pilot signal and the coded data for each data stream may be modulated (e.g., displayed in characters) based on a particular modulation scheme (for example, binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), M-ary phase shift keying (M-PSK) or M-ary quadrature amplitude modulation (M-QAM), and so on)selected for each respective data stream to provide modulation symbols. The data rate, coding and modulation for each data stream may be determined by instructions executing on the processing device 1130 and/or coming from it.

The modulation symbols for the data streams can be provided to the device 1120 processing MIMO transmission, which may further process the modulation symbols (e.g., for OFDM). Then the unit 1120 processing MIO transfer offers NTstreams of modulation symbols onNTtransceiver devices (RCVR/TMTR) 1122a-1122t. In a different implementation, the device 1120 processing MIMO transmission applies the weighting factors of formation of the pattern to the symbols of the data streams and to the antenna from which the symbol is transmitted.

Additionally,NTmodulated signals from transceiver devices 1022a-1022t transmitted fromNTantennas 1024a-1024t, respectively.

On a mobile device 1150, the transmitted modulated signals are received byNRantennas 1152a-1152r, and the received signal from each antenna 1152 is provided on the corresponding transceiver unit (TMTR/RCVR) 1154a-1154r.

The device 1160 processing data reception can receive and process theNRstreams of symbols taken fromNRtransceiver devices 1154 based on the processing technology specific receiving device to provideNT"discovered" streams of characters. The device 1160 processing of receive data can demodulate, subjected to reverse the interleaving and decoding of each detected symbol stream to recover the data information exchange for the data flow. Processing by the device 1160 processing of reception data is complementary to perform device 1020 processing MIMO transmission and device 1114 processing of data transmission to the base station 1110.

The processing unit 1170 may periodically determine the matrix pre-encoding to use, as discussed above. Additionally, the processing unit 1170 may generate a message for transmission on the reverse link, containing part of the index matrix and part of the estimated values.

The message for transmission over the return line may contain information different kinds regarding communication channel and/or accepted by the CMOS data. The message for transmission over the return line can be handled by the device 1138 processing data, which also receives data information exchange for the multiple data streams from a source 1136 data, modulated by a device 1180 modulation, pre-processed transceiver devices 1154a-1154r and transmitted back to the base station 1110.

At the base station 1110, the modulated signals from the mobile device are received by the antenna 1150 1124, pre-processed transceiver device 1122, demodulators device 1140 demodulation and processed by the device 1142 processing receive data to extract the message for transmission over the reverse link transmitted by the mobile device 1150. Additionally, the processing device 1130 may process the extracted message to determine the matrix pre-coding be used to determine the weights of the beam forming.

Processing device 1130 and 1170 may be employed (e.g., control, coordinate, organize, and so on) at the base station 1110 and the mobile device 1150, respectively. The corresponding processing device 1130 and 1170 may be associated with storage devices 1132 and 1172, which XP is adopted program codes and data. In addition, processing device 1130 and 1170 can perform calculations to obtain estimates of the frequency and impulse response for uplink communication and downlink, respectively.

FIELD: information technology.

SUBSTANCE: in one aspect, power control (PC) is supported in several PC modes such as "up-down" PC mode and delete-based PC mode. One PC mode may be selected for use. Service signals may be sent to indicate the selected PC mode. If the "up-down" PC mode is selected, the base station assesses the quality of the received signal for the terminal and sends PC commands in order to instruct the terminal to adjust its transmission power. If the delete-based PC mode is selected, the base station sends delete indicators which indicate whether code words received from the terminal are deleted or not. In both PC modes, the terminal controls its transmission power based on a power control feedback (e.g. a PC command and/or delete indicators) in order to attain the target level of efficiency (e.g. target deleting frequency for code words). Delete indicators may also be used for handover.

EFFECT: reduced noise and achieving high efficiency for all terminals.

SUBSTANCE: system uses switching ports to facilitate allocation and utilisation of sub-carriers. In one version, switching ports may be divided into several sub-zones, wherein each sub-zone includes a configurable number of switching ports. Switching ports in each sub-zone may be configured or moved based on a commutator function. After rearrangement, the switching ports in all sub-zones can be mapped to sub-carriers based on local or global switching.
