[0003] embodiments of the unified record format for General alarm control described in the joint application for U.S. patent No. 11/509 .697, entitled "Unified Entry Format For Common Control Signalling" ("Uniform format of accounts for General alarm management"), which generally included in this text by reference to the relevant document. Specified joint patent application relates to resource allocation for 3G and above, the technology of radio network of terrestrial access UMTS (E-UTRA) and, more specifically, to the structure of the table distribution is s (AT), also known as a shared channel signaling, a shared control channel (SCCH) or equivalent. The distribution table AT provides a means of delivering information channel SCCH all instances of user equipment UE within a cell.

[0004] advanced E-UTRA base station (enhanced node B - eNodeB) on the network side allocates radioresource and downlink DL and uplink communication specifies UL and resource allocation user equipment UE in the channel SCCH downlink. Channel SCCH carries other information common to all host instances of user equipment UE, such as indicators of search and call and response to the random access signal, not limited to. Additional information, such as confirmation of receipt of a previously transmitted uplink communication to schedule uplink UL communication and transport formats for distributed resources, is also present in the SCCH channel.

[0005] a record of the allocation of resources for a given user equipment UE has a pre-defined structure (standardized format). However, the number of instances of user equipment UE, which allocates resources in descending DL and rising UL communication lines can edit the change from Subhadra to Subhadra, and thus, the number of entries in the allocation table (AT) resources can be volatile. Therefore, the volume of the alarm control passed in a given subcate in downlink may differ from Subhadra to Subhadra.

[0006] the Use of high-speed channel SCCH (HS-SCCH) in the HSDPA system, that is specific to the user equipment UE alarm management, will introduce an undesirable amount of proprietary information due to the tail bits block coding and redundancy bit fields for alarm confirmation/denial of acknowledgment (ACK/NACK). In the system of E-UTRA unlike systems HSDPA resource allocation ascending line UL are also transmitted in the channel SCCH downlink DL. Additionally, the SCCH channel downlink DL can be transmitted to the other control information associated with the resource allocation uplink UL communication, such as capacity management and proactive synchronization. In addition, there are some specific bit fields that may be present, such as indicators of search challenge that is shared by two or more instances of user equipment UE, and the response to the random access signal, which is shared by an arbitrary instances subscriber equipped with the I UE, trying to get random access to the network. Thus, the use of specific user equipment UE schemes alarm undesirable. On the contrary, from the point of view of the amount of overhead and processing, it is preferable to transmit the alarm multiple instances of user equipment UE in one unit and jointly encode the control signals of multiple UE, respectively.

[0007] In case of joint encoding of the shared control signal downlink multiple instances of data management (alarm bit field) are combined into a single block that is encoded code FECC. However, since the length of the coded block field alarm management depends on many sources of data management, field length may be variable, as noted above, and user equipment UE which decodes the channel SCCH, it is necessary to know the length of the coded block. One possibility is to blind decoding, but the number of possibilities is so large that this scheme is not feasible. Alternatively, the user equipment UE can communicate about the length of the encoded field by signaling a higher level. However, one can show that this approach is too slow and inflexible for the purposes of the detection level L1. This is Hema will actually limit performance and increase the wait time at the processing level L1.

[0008] a Unified coding and modulation channel SCCH downlink DL provide the lowest amount of service data coding, but they show some drawbacks. Because all instances of user equipment UE in the cell area must be able to detect and decode the SCCH channel, speed channel coding must be defined for the most challenging reception conditions, and the encoding speed must be low enough to ensure a high quality of decoding even on the edge of the cell. Practically, you may need to set the encoding speed (code) is so low that the overhead channel SCCH for throughput downlink DL will become unacceptable.

DETAILED DESCRIPTION

[0028] embodiments of the present invention relate at least partly to the physical structure of the shared control signal downlink DL and, in particular, to the separation of the control channel to separately coded fields.

[0029] the Use of embodiments of the present invention allows to overcome the above problems. For example, in signaling HSDPA WCDMA system, each subscriber equipment UE detects one code forming channels from the set of codes forming channels HS-SCCH available in the downlink DL and, thus, the channel HS-SCCH is always a block channel coding with constant length, since the control signal is constant, definite and specific on what I individual user equipment UE at the same time. Alarm management, which is jointly encoded for multiple UE in WCDMA system is not used.

[0030] embodiments of the present invention relate to a system UTRAN-LTE and are discussed below in context. More specifically, embodiments of the present invention apply to the field of alarm about resource allocation and management of subscriber equipment UE for reception on the downlink and passing upward through channel signaling downlink DL. This implies that the node base station is responsible for resource allocation and management for communication in both directions. However, it should be clear that at least some aspects of embodiments of the invention are applicable to other types of wireless communication systems. In General, it is possible that the interacting nodes can be devices of the same type, but only one of these devices plays a dominant role in the determination of resource reservation in the air.

[0031] Refer first to figure 9 for illustration of a simplified block diagram of various electronic devices that are suitable for use in the implementation in practice of embodiments of the present invention. Figure 9 wireless network 1 is made with the possibility of communication with the user equipment UE 1 via the node B (base station) 12, also called sometimes a node eNodeB. The network 1 may include a controller RNC 14, or, more commonly, some service control node, which may be called by the serving radio network controller RNC (SRNC)or serving node packet radio (eGSN), or, more commonly, a "node". The user equipment UE 10 includes a CPU 10A data processing (DP), memory (MEM) 10B that stores a program (PROG) 10C, and a suitable radio frequency (RF) transceiver 10D for bidirectional wireless communications with the node 12, which also contains the processor DP 12A, the memory device MEM 12B that stores a program PROG 12C, and a suitable RF transceiver 12D. The node 12 is connected via a channel 13 data transfer with the host 14, which also includes a processor DP 14A and a storage device MEM 14B that stores the associated program PROG 14C.

[0032] In a typical case, there is a lot of user equipments UE 10 located in the cell served by the node 12. The user equipment UE is usually experiencing dynamic changes of the signal-to-interference (SIR) at the reception, and this particularly applies to one or more UE 10 that may be located on the edge of the cell or around it.

[0033] As will be discussed below, at least the PROG 10C and 12C include software instructions that, when execution of the corresponding process is litter DP, enable the electronic device to operate in accordance with embodiments of the present invention. For example, the program PROG 12C includes software instructions that cause the host 12 to transmit signals to subscriber equipment UE 10 and the other UE in the same cell using separated and separately encoded channel SCCH downlink DL, and the program PROG 10C includes software instructions that cause the user equipment UE 10 to take the SCCH channel downlink DL and selectively decode the different sections of the same channel SCCH downlink DL, as will be discussed below in more detail.

[0034] Thus, embodiments of the present invention may be implemented at least partially using computer software executable by the processor DP 10A of user equipment UE 10 and the other DP processors, such as processors that communicate with a processor DP network, or hardware, or a combination of software and/or hardware-software and hardware.

[0035] In General, various embodiments of user equipment UE 10 can include, but is not limited to the following:

cell phones, personal digital assistants (PDA) with radio communications, portable computers with the power Radiocommunication devices capture images, such as digital cameras, with the possibility of the radio gaming device with radio communication, storage devices and play music with radio communication device to the Internet, providing wireless access to the Internet and view web pages, as well as portable units or terminals that incorporate combinations of such functions.

[0036] the Memory device MEM 10, 12 and 14 can be of any type suitable to the local technical environment and may be implemented using any suitable data storage technology, such as mass storage devices based on semiconductors, magnetic memory devices and systems, optical memory devices and systems, fixed memory device and the removable mass storage device. The processors of the data processing (DP) 10A, 12A and 14A may be of any type suitable to the local technical environment, and may include as examples, not limitations, one or more General purpose computers, special purpose computers, microprocessors, digital signal processors (DSPS) and processors based on a multicore architecture.

[0037] Thus, the above considered suitable, but not limiting the invention in the technical context for the application in practice of embodiments of the present invention, which now badurashvili in more detail with reference to figures 1-8 and 10.

[0038] Examples of embodiments of this invention provide for the SCCH channel downlink DL, which is divided at least into two parts, and determine how the SCCH channel downlink DL is mapped onto physical resources. The first section of the channel SCCH downlink DL has a constant length in units of modulated symbols, channel coding and is located in a predetermined position of the resource subcode shared physical channel downlink DL with known modulation and channel coding. The first section contains header field, which indicates the presence (or absence) of the last section (or the last sections), as well as the location of the resource and the structure of the last section(s), if available. Information about the physical structure of the last section may include a transport format schema channel coding and modulation or at least in the form of a length of the encoded field. The transport format may optionally include, as examples, not limitations, data on whether special processing techniques with multiple antennas, such as beamforming and/or space-time block code (STBC), space-frequency block code (SFBC) or explode with cyclic the delay (CDD). The scheme, channel coding and modulation the last section may differ from the channel coding scheme and modulation of the first partition, and it can vary from Subhadra to Subhadra. It is also possible that the last section(s) has a constant transport format, and the first section indicates the number of the last partition.

[0039] a Particular example of the use of various power transmission in the context of division of physical resources of the control channel is the necessity of taking into account soft reuse frequencies (SFR) in the downlink DL. For example, the first section of the channel SCCH can only use the physical resources assigned to the profiles with high transmit power. However, the embodiments of the present invention is not limited to the use of SFR, and two or more sections can take the physical resources assigned to the profiles with high transmit power, if necessary.

[0040] the Last section may contain two or any other number of individual fields, and one field provides a more robust coding scheme and modulation or higher transmit power than another. None of the sections should not be limited to a specified part of subcarriers in the case of SFR, and all can take even subcarriers profiles with high transmit power.

[0041] in Contrast is the W on the concept of SFR can be found, for example, in a document called "Soft Frequency Reuse Scheme for UTRAN LTE", 3GPP TSG RAN WG1 Meeting #41, Athens, Greece, 9-13 May 2005, R1 -050507, Source: Huawei ("Scheme soft re-use of frequencies for UTRAN LTE")attached to this description as a document and is incorporated in this description by reference to the relevant document. SFR is the scheme used in the system with many carriers, for example OFDM system, where some part of the band (some sets of subcarriers) is transmitted with higher power than other parts of the band (other sets of subcarriers). This type of profiling power in the frequency domain changes the ratio of received signal to interference as a function of frequency, and allows you to get the win. How the SFR is also used in asynchronous global network, as the pattern frequency is stable and does not require time coordination.

[0042] In accordance with embodiments of this invention, the pilot symbols (or reference REF figure 1 and 2) are frequency-multiplexed with the first section of the channel SCCH. Thus, depending on the actual density and the positions of the pilot symbols for the SCCH set to a constant length of the individual resources of the OFDM symbol (or its share of the power profile SFR), excluding the subcarriers carrying the modulated pilot symbols. This implies that, even if PL is tnost pilot symbols may be different in different areas of the cell, it does not change the a priori knowledge that the user equipment UE 10 has a first section SCCH.

[0043] In one example embodiment of the invention there is a constant number (three in the example shown in figure 3) distributions DL UE assigned to the first partition allocation table AT, in addition to the field of display of the search call and header field. All other allocation for downlink DL, allocation for uplink connection, UL, field ACK/NACK and other shared alarm control is located in the second section of the channel SCCH.

[0044] In another example embodiment of the invention the first section of fixed length channel SCCH downlink DL transfers only the header field and the indicators of the search call. The last section consists of at least two variable length fields, one of which can use a lower bit rate and modulation scheme of a lower order or higher transmit power than others. Both fields in the last section are resource allocation for DL and UL. In this embodiment of the invention, the scheduler of the node b can allocate the control signals intended for those UE 10, which are located on the edge of the cell or near field control signal with the encoding with lower speed and schema module the AI lower order and/or higher transmission power, while the UE 10, which are located closer to the center of the cell, have a distribution that is placed in the field control signal, having a coding faster and perhaps even modulation scheme is of a higher order and/or lower transmit power.

[0045] as an example, not limiting the present invention, the encoding rate of the first partition may be of the order of 1/8 to 1/6 convolutional code, and in the following sections with lower speed encoding encoding speed can be in the range of from 1/6 to 1/3 convolutional code, and a higher encoding speed can be in the range of about 1/3 to 1/2 convolutional code. Turbocode or concatenated codes similarly available in the alternative, if so specified in the standard specifications of the system. As an example, not limiting the invention, the modulation scheme of a lower order may use quadrature phase shift keying QPSK and the modulation scheme is of a higher order can use 8-point phase shift keying (8PSK), 16-point quadrature amplitude modulation (16QAM), 64-point quadrature amplitude modulation (64QAM) or any modulation with multiple antennas.

[0046] Further examples of embodiments of the present invention are discussed in more p is explored with reference to figures 1-8.

[0047] Figure 1 illustrates a method of separating channel SCCH into two sections, i.e. two block channel coding (called SCCH part I and part II SCCH) in accordance with the variant example of implementation of the present invention. The first part (part I) is displayed on persistent blocks 20 physical resources having a fixed, known in advance modulation and coding. This is known in advance the format of modulation and coding can be written in the specification or indicated, for example, in the system information transmitted on the broadcast channel. The second part (part II) is displayed on a variable number of blocks 22 physical resources with variable modulation and coding. Physical resources, modulation, coding, beamforming and similar parameters of the transport format of the second part SCCH described in the first part of the SCCH. Figure 1 assumes the use of SFR, thus, the first part SCCH uses physical resources only profiles with high transmit power. The above-mentioned pilot symbols (basic symbols) shows scattered (multiplexed by frequency or frequency and time) among the OFDM symbols to the left in figure 1.

[0048] Figure 2 illustrates how to display the control channel that does not use SFR or which omits existing SFR, in accordance with an additional example var is Anta implementation of the present invention to separate SCCH two sections, that is, two block channel coding (also called SCCH part I and part II SCCH). The first part (part I) is displayed on persistent blocks 20 physical resources having a fixed, known in advance modulation and coding. The second part (part II) is displayed on a variable number of blocks 22 physical resources with variable modulation and encoding.

Physical resources, modulation, coding, beamforming and similar parameters of the transport format of the second part SCCH described in the first part of the SCCH. It should be noted that according to the scheme in figure 2, even if the SFR was used, the first part SCCH lowers it and uses fully the physical resources of the first OFDM symbol except the reference (pilot) symbols.

[0049] Each of the figures 1 and 2 clearly shows that the control channel SCCH downlink DL is divided at least into two parts 20, 22, each of which is distributed over frequency. This distribution in terms of frequency is presented in the form of an example distributed groups of subcarriers (e.g., OFDM). Thus, the partition allocation table AT can be displayed on different sets of subcarriers. The first section is displayed on a portion of the frequency band, which consists of a constant number of blocks of physical resources, as discussed above, each of them is the set of subcarriers. For the CSOs to pass sections adaptive, so to distinguish between the user equipment UE at the edge of the cell from closer to the center of the cell, one of the sections can be transmitted in one part of the frequency band through the first set of subcarriers) with higher power, and the other can be transmitted in a different part of the frequency band through the second set of subcarriers) with lower power.

[0050] figure 3 depicts an example of a variant of the first constant section 20 SCCH channel downlink DL. In this embodiment, not limiting the invention, the first section 20 (a constant length) contains the header 30 of the allocation table AT, including information 30A to specify the transport format for the second section 22, such as length scheme (MCS), the beamforming scheme transmission with multiple antennas, and so forth, the information required subscriber equipment UE 10 for receiving and correctly decoding the second partition 22. There may be many (e.g., a constant number of) specific to the user equipment UE records 32 distributions and other additional information 34 to define indicators of search challenge or confirm the previous distributions.

[0051] figure 4 depicts the second section 22 of variable length channel SCCH downlink DL. In this case also the may be many specific to the user equipment UE records 36 distributions (which are not reported in the first section 20), as well as information 38 that provides the rest of the allocation table, for example, account for the upward communication line UL, including (sometimes) information about the management capacity, ahead of synchronization, acknowledgement, etc.

[0052] figure 5 shows another variant of implementation of the first (continuous) section of the channel SCCH downlink DL, in this case, it contains only the header 30 of the allocation table AT and indicators 34 search call (perhaps also a response to the RACH signal), as figure 3, but without specific user equipment UE records 32. In this case, all records of the distribution of UE will be transferred to the second section 22 (for example, as Fig).

[0053] figure 6 shows another variant implementation of the second section 38 of the channel SCCH downlink DL, in which the second section 38 is provided as two (or more) of section 38A, 38B, which are transmitted using different schemes (MCS). For example, one MCS (such as the scheme for section 38A) provides less robust coding scheme and/or modulation than the other. As noted above, a more sustainable scheme (MCS) can be used UE 10 near the edge of the cell (subscriber equipment UE 1, 2, and 3 in this example), whereas less stable scheme (MCS) can be used UE 10 that is closer to the node 12 (the user equipment UE 4, 5 and 6 in this paragraph is the iMER).

[0054] figure 7 shows another variant of implementation of the first (continuous) section of the channel SCCH downlink DL, in this case, it contains the identifiers, such as C_RNTI, for those UE 10, which have the allocation of resources in the second section. This specific structure of the alarm system is well suited for use in broadband downlink DL, where the first section 20 has sufficient bandwidth to transfer the necessary information alarm.

[0055] C_RNTI is a unique identifier of the user equipment UE 10 (terminal) in the actions pane serving base station (node 12). ID C_RNTI is applied, for example, to declare distributions of resources for user equipment UE 10 for reception of the downlink DL (information planning downlink) and perform resource reservation for the user equipment UE 10 to transmit on the uplink connection UL (planned giving resource ascending line).

[0056] Fig illustrates another variant implementation of the second section 38 of the channel SCCH downlink DL, in this case he transfers all records for distributions UE 10.

[0057] it Should be noted that, since the alarm can be expected to be insufficient and the number of bit fields will be designed is very effective alarm C_RNTI actually consumes the most bandwidth signaling. Thus, the number of user equipments UE 10 to transmit the alarm during the time interval of transmission (usually one Subhadra, although sometimes more than one Subhadra) plays a significant role in the efficiency of the layout Subhadra, efficiency multiplayer planning, and on the other hand, the amount of overhead signaling.

[0058] In accordance with another variant example of implementation of this invention, which is applicable to any of the schemes discussed above, the identifier C_RNTI can be transmitted only once in the case, when there is an allocation of downlink and distribution of uplink communication for the same user equipment UE 10 in a given subcate. This implies that there are notes on the distribution, including records only for downlink, records only for uplink communications and records for ascending and descending lines. This is easily accounted for by adding, for example, the case of double-bit direction indicator line that indicates whether the description of the allocation for downlink to uplink communication or for uplink communications and downlink. An alternative might add is taken a bit field constant length, which specifies the number of entries only for the upward communication line UL and the number of entries only for downlink DL. When recording on alarm indicates the distribution and downlink, and uplink communication, the recording format supports independent field of transport format for the descending and ascending lines, respectively. Saving bits due to the lack of redundant signaling C_RNTI remains significant. In practice it may often happen that the records indicate the distribution are arranged so that the procedure to some extent was descriptive for distribution. Thus, it will be advisable to arrange the alarm, for example, so that the distribution of the uplink UL communication appeared first in mutually ordered list and allocation of downlink appeared in the following mutually sorted list. In this case, there is a need to include, as part of the record on the distribution of the upward communication line UL, also related consolidated alarm downlink. However, this leads to the fact that the alarm downlink DL loses its place in the ordered list of the distribution of the downlink DL. Thus, examples of embodiments of the present invention may include PR the stop mechanism to overcome this by including in the joint account on the alarm for ascending and descending lines UL-DL pointer (index) to the entry position of the sorted list downlink. This index lists the alarm is not a problem for any user equipment UE 10, as all information is in any case included in the jointly coded block which must be decoded by all subscriber equipments UE 10. Any subscriber equipment UE 10, therefore, must be capable of decoding the coded block and handle field alarm having to do with it. Further, regarding the ordering is possible to only order the distribution of the upward communication line (allocated blocks neighboring frequencies) played a role in the ordering of the list, and the order of the descending line (distributed any flexible blocks of frequencies) performed no function. In this case, the index can be omitted, and provides only an indicator for the direction of the line of distribution.

[0059] Thus, examples of embodiments of this invention, as shown in figure 10, provides a way of sending information to multiple UE from a network node, such as node B, the method includes a separation channel SCCH downlink DL on the first section of fixed length and at least one second section of variable length (step a) and the transfer of the divided SCCH channel in downlink DL user equipments UE 10 (step In).

[0060] the First section paradieses by using the transport format, previously known subscriber equipment UE for receiving and decoding this subscriber equipment UE, and includes information to inform many UE transport format, such as at least the length and the scheme (MCS) at least one second section in order to enable the subscriber equipment UE to receive and decode at least one second section.

[0061] the Second section may optionally be embedded in one or more blocks of channel coding, where each of the previous, potentially more sustainable units of encoding includes the alarm about the transport format and resource next, less stable block(s) channel coding.
