Description

Method and device for configuring resource mapping indication information

The present invention relates to the field of communications, and in particular, to a method and a device for configuring resource mapping indication information.

Background technique

In a wireless communication system, a base station generally refers to a radio transceiver station capable of transmitting information through a mobile communication switching center and a terminal in a certain radio coverage area. In practical applications, the base station can communicate with the terminal through the uplink/downlink, where the downlink refers to the transmission direction of the base station to the terminal, and the uplink refers to the transmission direction of the terminal to the base station. A plurality of terminals can simultaneously transmit data to the base station through the uplink, or can simultaneously receive data from the base station through the downlink. In addition, the transmitted data can be relayed between the base station and the terminal through the relay station.

In a wireless communication system in which a base station implements radio resource scheduling control, scheduling allocation of system radio resources is performed by a base station. For example, the downlink resource allocation information used by the base station for downlink transmission and the uplink resource allocation information required for the terminal to perform uplink transmission may be given by the base station.

In a communication system based on Orthogonal Frequency Division Multiplexing (OFDM) and Orthogonal Frequency Division Multiple Address (OFDMA) technologies, for example, in Long Term Evolution (Long Term) Evolution, referred to as LTE), Ultra Mobile Broadband (UMB), and Institute for Electrical and Electronic Engineers (IEEE) 802.16m wireless communication systems, wireless resources Although it is also divided into frames for management, each OFDMA symbol includes a plurality of mutually orthogonal subcarriers, and the terminal usually occupies part of the subcarriers, thereby enabling partial frequency reuse (FFR). The technology is used to reduce the interference and improve the coverage. Secondly, due to the frequent changes of the wireless channel environment, the base station divides the available physical subcarriers into physical resource units (PRUs) in order to obtain the frequency diversity gain and the frequency selective scheduling gain. ), and then map physical resource units It is a Contiguous Resource Unit (CRU) and a Distributed Resource Unit (DRU) to improve transmission performance. The subcarriers in the continuous resource unit are continuous, and the resource elements are distributed. The subcarriers in the subcarrier are completely discontinuous or incompletely continuous; in addition, as the frequency resources become increasingly scarce, the base station needs to support multiple different bandwidths (for example, 5 MHz, 10 MHz or 20 MHz, and the system bandwidth can be different in some OFDM systems). The FFT points, sometimes the system bandwidth is also called bandwidth) or multi-carrier operation to take advantage of different frequency resources and meet the needs of different operators. It can be seen that the resource mapping process of the wireless communication system considering the OFDM or OFDMA technology will be complicated. In order to reduce the indication signaling overhead of the resource mapping and optimize the system information management and transmission method, a reasonable resource mapping is needed. In order to ensure the efficiency of the wireless communication system, the base station usually maps the physical radio resources into logical radio resources, for example, mapping physical subcarriers into logical resource units, and the base station implements scheduling of radio resources by scheduling logical resource units.

Specifically, for a OFDM or OFDMA-based wireless communication system, the radio resource mapping is mainly based on the frame structure and resource structure of the wireless communication system, the frame structure describes the control structure of the radio resource in the time domain, and the resource structure describes the radio resource in the Control structure in the frequency domain. The frame structure divides radio resources into different levels of units in the time domain, such as Superframes, Frames, Subframes, and Symbols, by setting different control channels (for example, broadcasting). Channel, unicast, and multicast channels, etc.) implement scheduling control.

For example, FIG. 1 is a schematic diagram of a frame structure of a wireless communication system according to the related art. As shown in FIG. 1, a radio resource is divided into super frames in a time domain, and each super frame includes 4 frames, and each frame includes 8 subframes. Each subframe is composed of 6 basic OFDMA symbols, and the actual system determines how many OFDMA symbols are included in each level unit in the frame structure according to factors such as bandwidth to be supported and/or cyclic prefix length of the OFDMA symbol; Setting a broadcast channel in the first downlink subframe in the superframe (because it is located in the superframe header, also called a superframe header) and transmitting system information such as resource mapping; and the system can also set unicast and / or multicast control channel to send scheduling control information such as resource allocation.

According to the networking technology, the interference suppression technology, and the service type, the resource structure divides the available bandwidth in the frequency domain into multiple frequency partitions (Frequency Partitions, FP for short), and then the frequency.

2 is a schematic diagram of a resource structure of a wireless communication system according to the related art. As shown in FIG. 2, available physical subcarriers of one subframe are divided into three frequency partitions, and each frequency partition is divided into continuous resources and distributed resource units, and continuous resources. The unit is used for frequency selective scheduling, and the distributed resource unit is used for frequency diversity scheduling.

The resource mapping method generally needs to support 5MHz, 7MHz, 8.75MHz, 10MHz and 20MHz system bandwidth (referred to as bandwidth), and 5MHz, 7MHz, 8.75MHz when partial protection subcarriers are used to map PRUs without considering multi-carrier operation. In the 10MHz and 20MHz bandwidths, the number of corresponding PRUs is 24, 48, 48, 48, and 96, and there is a corresponding relationship between the bandwidth and the number of PRUs. Therefore, the indication parameters of resource mapping under different system bandwidths are different. For example, a system with a bandwidth of 5 MHz has 24 PRUs per subframe, and when 4 PRUs form a subband, there are up to 6 Subbands, and a 7 MHz, 8.75 MHz, or 10 MHz system has 48 PRUs. There are at most 12 Subbands. For these two systems, Subband Allocation Count (SAC) needs to be set differently to save overhead. It should be noted that in some OFDM or OFDMA communication systems (for example, Worldwide Interoperability for Microwave Access (Wimax) 16m communication system), bandwidth and system Fast Fourier Transformation (Fast Fourier Transformation, Referred to as FFT) the number of points exists - the corresponding relationship, that is, only know the bandwidth of the system, you can determine the FFT points of the system. For example, the 5MHz bandwidth system corresponds to the 512-point FFT transform, and the system bandwidth is greater than 5MHZ and less than or equal to 10MHZ (for example The 7MHz, 8.75MHz and 10MHz bandwidth systems correspond to a 1024-point FFT transform with a system bandwidth greater than 10 MHz less than or equal to 20 MHz (eg, a 20 MHz bandwidth system) corresponding to a 2048-point FFT transform. Some of the bandwidth conditions described below also correspond to their corresponding system FFT points. For example, when referring to a 5 MHz bandwidth system, it can also represent a system using a 512-point FFT. The following describes the implementation of resource mapping according to different bandwidths: The downlink resource mapping process usually includes: Subband Partitioning, Miniband Permutation, Frequency Partitioning, Continuous Resource Unit/ Contigous Resource Unit/Distributed Resource Unit Allocation (CRU/DRU Allocation) and Subcarrier Permutation; The uplink resource mapping process includes: Subband division, Miniband Permutation, Frequency Partitioning, contiguous resource unit/distributed resource unit allocation and Tile Permutation „ Subband consists of N1 consecutive PRUs, for example, N1 = 4, and Miniband consists of N2 consecutive PRUs, for example, N2 = 1.

Fig. 3 is a specific example of physical resource mapping in the case of a 5 MHz bandwidth, including a process of contiguous resource unit/distributed resource unit allocation. 4 is a schematic diagram of a subband division process of a wireless communication system according to a 5 MHz bandwidth of the related art, and FIG. 5 is a schematic diagram of a microstrip replacement process of a wireless communication system according to a related art, and FIG. 6 is a schematic diagram of a microstrip replacement process according to the related art. Schematic diagram of frequency partitioning of a wireless communication system with a 5 MHz bandwidth.

As shown in FIG. 3, the downlink subframe resource mapping process of the 5 MHz OFDMA system is described. PRUSB refers to the PRU for Subband, PRU _MB refers to the PRU for Miniband, PPRUMB refers to the PRU through Miniband Permutation, and PRU _FPi refers to the PRU that belongs to the i (ii > 0) frequency partition. The FFT point number of the 5 MHz system is 512, and the number of available data subcarriers in the sub-frame is 432, which is divided into N=24 PRUs, each PRU size is 18x6, that is, frequency i or 18 carriers, and the time domain is 6 The number of symbols on the time domain may be 5 or 7 due to cyclic prefix, superframe header, transition point, and control channel.

The following takes the 5MHz bandwidth as an example to introduce the various steps of physical resource mapping: (1) Subband division, that is, extracting a part of PRUs into Subbands in units of one Subband. The number of downlink subbands and the number of uplink subbands are respectively indicated by two parameters: Downlink Subband Allocation Count (referred to as DS AC) and Uplink Subband Allocation Count (USAC). For example, the following 5 MHz bandwidth is used. When the number of downlink Subbands indicated by the DSAC is 3, 12 PRUs are mapped to 3 Subbands. As shown in Figure 4, the base station uses DSAC to indicate Subband Partitioning, obtains PRU _SB (blank portion in the figure), and maps the remaining portion to Miniband, as shown in the figure, PRU _MB (the part of the padding in the figure).

(2) Start band replacement, that is, map PRUs that are not mapped to Subband to Miniband. When the number of downlink Subbands indicated by the DSAC is 3 in the 5 MHz bandwidth, 12 PRUs are mapped to the Miniband. As shown in Figure 5, the 12 PRUs are replaced. This step does not require additional parameter indications, which is done according to DSAC. Similarly, the upstream microstrip replacement is done according to the US AC.

(3) Frequency partitioning, that is, dividing the divided Subband and the replaced Miniband into frequency bins. This step requires two parameters, one for indicating the number, size, and/or proportion of each frequency partition. The downlink and uplink are respectively configured by Downlink Frequency Partition Configuration (DFPC) and uplink frequency partition configuration (Uplink). Frequency Partition Configuration (UFPC for short) indication; another parameter is used to indicate the number of Subbands in the frequency partition other than the first frequency partition (ie, FP.), and the downlink and uplink are respectively allocated by the downlink frequency partition subband ( Downlink Frequency Partition Subband Count (referred to as DFPSC) and Uplink Frequency Partition Subband Count (UFPSC). Under the condition that the size of the frequency partition other than the first frequency partition is equal to the number of subbands included, a certain redundancy reduction can be performed, and some impossible values are removed. As shown in Figure 6, except for the first frequency partition size of 24 PRUs, the other frequency partition size is 0, and the frequency partitions of other frequency partitions are 0.

(4) Continuous resource unit/distributed resource unit allocation, that is, separate resource unit/distributed resource unit allocation is performed separately for each frequency partition. The downlink frequency partition is indicated by the Downlink CRU Allocation Size (DC AS), and the uplink frequency partition is indicated by the Uplink CRU Allocation Size (UCAS). If the size of some frequency partitions is 0, you do not need to carry this parameter. As shown in Figure 3, when the system bandwidth is 5MHz, the number of downlink Subbands indicated by DSAC is 3, the size of the first frequency partition is 24 PRUs, the size of other frequency partitions is 0, and the number of CRUs of the first frequency partition is Schematic diagram of 12, where the blank portion on the last column indicates the CRU, the portion of the filled grid It means DRU. It should be noted that, by using one bit, it is indicated whether the Subband is used as the CRU by default, and the Miniband is used as the DRU by default. In this case, the DC AS or the UCAS may not be transmitted to further save the overhead.

(5) Subcarrier permutation or tile permutation, that is, subcarrier replacement for PRUs mapped to DRUs in each frequency partition in the downlink subframe, and PRUs for mapping to DRUs in respective frequency partitions in the uplink subframe Perform a Tile replacement.

Additionally, the CRUs and DRUs described herein refer to resource elements that have not yet passed through step (5). After the fifth step, the Contiguous Logical Resource Unit (CLRU) and the Distributed Logical Resource Unit (DLRU) can be used without any ambiguity. CLRU and DLRU are simply referred to as CRU and DRU.

In order to more clearly explain the case of resource mapping under other bandwidths, FIG. 7 is a schematic diagram of a resource mapping process of a wireless communication system according to a related art 10 MHz (which may be 7 MHz or 8.75 MHz) bandwidth, and FIG. 7 shows 10 MHz (also included 7MHz, 8.75MHz) The specific mapping situation in bandwidth, FPSi refers to the number of PRUs in the i (i > 0) frequency partitions, where the number of Subbands is 6, and there are 4 frequency partitions, each frequency partition size is For 12 PRUs, the first frequency partition contains 8 CRUs and 4 DRUs, and the other frequency partitions contain 4 CRUs and 8 DRUs.

8 is a schematic diagram of a resource mapping process of a wireless communication system in the case of a 20 MHz bandwidth according to the related art, and FIG. 8 shows a case of a specific mapping in the case of a 20 M bandwidth, where UCAS _SB1 refers to an i-th (i > 0) frequency partition. The number of uplink sub-based CRU allocations, UCAS _MB refers to the number of uplink Miniband-based CRU allocations in each frequency partition.

As can be seen from the above description, in the resource mapping process, after the bandwidth is determined, other parameters need to be determined (for example, the number of Subbands, the number of frequency partitions, the number of Subbands and CRUs on each frequency partition, etc.) need to be determined.

In the communication system, the resource mapping indication information is sent by the base station to the terminal through the broadcast channel or the superframe, and the terminal determines the resource location of receiving and/or transmitting data according to the resource mapping indication information and the resource allocation information. The resource mapping indication information indicates the division and mapping of the frequency resources, and specifically includes the following information: downlink subband allocation number, uplink subband allocation number, downlink frequency partition configuration, uplink frequency partition configuration, downlink frequency partition subband allocation number, uplink The number of frequency partition subband allocations, the number of downlink contiguous resource unit allocations, the number of uplink contiguous resource unit allocations, the number of downlink contiguous resource units based on Miniband, and the number of contiguous resource units based on Miniband. Since the specific resource mapping process is many, the setting of the above indication parameters has strong flexibility, but at the same time, the number of bits required to indicate these parameters is increased, thereby increasing the control when transmitting these bits. Channel overhead, wasting a lot of channel resources. In view of the problem that the resource mapping parameter indication in the related art and the channel overhead of transmission are large and the system resources are wasted, an effective solution has not been proposed yet.

detailed description

An embodiment of the present invention provides a configuration scheme of resource mapping indication information, where a certain number of bits are used to indicate at least one parameter of a resource mapping, where, for each bandwidth supported by the system, the number of bits used by the parameter is indicated, so that In the small bandwidth case, the number of bits used for parameter indication is less than that of the large bandwidth. The number of bits used by the physical resource mapping indication signaling is reduced, and the bandwidth used by the system can be flexibly without affecting the normal operation of the system. The change saves the downlink control overhead. That is, an information element (Information Element, IE for short) or a message or a sub-packet that transmits the resource mapping indication information in the broadcast channel or the super-frame header is determined according to the system bandwidth, thereby improving the working efficiency of the system.

It should be noted that the features in the embodiments and the embodiments in the present application may be combined with each other without conflict. The invention will be described in detail below with reference to the drawings in conjunction with the embodiments.

In the following embodiments, the steps shown in the flowchart of the accompanying drawings may be performed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flowchart, in some In this case, the steps shown or described may be performed in a different order than the ones described herein.

According to an embodiment of the present invention, a method for configuring resource mapping indication information is provided.

FIG. 9 is a flowchart of a method for configuring resource mapping indication information according to an embodiment of the present invention. As shown in FIG. 9, the method includes the following steps: ^^

Step S902: Indicate, by using a certain number of bits, at least one parameter of the resource mapping, where the number of bits used to indicate the parameter is determined according to the bandwidth, and for a plurality of different bandwidths, the number of bits required to indicate the parameter is partially identical to each other or completely different.

In this embodiment, according to the bandwidth, the number of bits used for each bandwidth configuration indication parameter supported by the system is such that the number of indicated indications in different bandwidths is not completely the same, so that the number of bits used by the physical resource mapping indication signaling can be determined according to the system. The bandwidth used is flexibly changed, the number of transmitted bits is reduced as much as possible, and the problem of large control channel overhead in the related art is avoided.

Preferably, determining the number of bits used to indicate the parameter according to the bandwidth comprises: determining a number of FFT points of the system according to the bandwidth, and determining a number of bits used to indicate the parameter according to the number of FFT points.

Since the bandwidth can be determined once the FFT point is determined, that is, the bandwidth can be corresponding to the corresponding FFT point, and the FFT point number is also a commonly used system parameter, and the number of bits used to indicate the parameter can be relatively easily determined by using the FFT point number, and the enhancement is performed. The utility of this embodiment.

Preferably, the resource mapping includes a downlink resource mapping and/or an uplink resource mapping, where the downlink resource mapping includes at least one of the following: subband division, microstrip replacement, frequency partition division, continuous resource unit/distributed resource unit allocation, and subcarrier replacement. The uplink resource mapping includes at least one of the following: Subband partitioning, microstrip permutation, frequency partition partitioning, continuous resource unit/distributed resource unit allocation, and

Tile replacement. The foregoing content is a common step of resource mapping. Therefore, this embodiment can satisfy most resource mapping scenarios.

Preferably, the plurality of different bandwidths include a first bandwidth, a second bandwidth, and a third bandwidth, where, for one parameter in the resource mapping indication information: corresponding to the first bandwidth, indicating that the number of bits used by the parameter is M; Corresponding to the second bandwidth, indicating that the number of bits used by the parameter is N; corresponding to the third bandwidth, indicating that the number of bits used by the parameter is P, where the values of M, N, and P include: N=M+ 1. JL P=M+1; or, N=M+2, and P=M+2; or, N=M, JL P=M+1; or, N=M, and P=M+2; Or, N=M+1, and P=M+2; or, N=M+2, and P=M+3; or N=M+1, JL P=M+3, where M is greater than 0 Integer. In this embodiment, the values of M, N, and P may be different, or two of them may be the same, and the other is different. In addition, embodiments of the present invention are not limited to three different bandwidths. If there are more than three different bandwidths, then the number of bits corresponding to the bandwidth is more than three, and the number of these bits may be different, or the number of bits in the part may be the same, and the remaining number of bits is different.

Preferably, the value of M is 1 or 2 or 3 or 4. These values belong to the range of values of the number of bits of the commonly used indication parameter, so this embodiment can be applied to most scenes indicating the number of bits of the parameter.

Preferably, the first bandwidth comprises: 5MHz (or a bandwidth corresponding to the 512-point FFT system), and the second bandwidth includes one of the following: 7MHz, 8.75MHz, 10MHz (or bandwidth corresponding to the 1024-point FFT system), the third bandwidth Including: 20MHz (or 2048 point FFT system corresponding bandwidth). These bandwidths are a common bandwidth range, so this embodiment can satisfy most bandwidth applications.

Preferably, the parameter in the resource mapping indication information includes at least one of the following: a downlink subband allocation number, an uplink subband allocation number, a downlink frequency partition configuration, an uplink frequency partition configuration, a downlink frequency partition subband allocation number, and an uplink frequency partition subroutine. The number of allocations, the number of downlink contiguous resource unit allocations, the number of uplink contiguous resource unit allocations, the number of downlink contiguous resource units based on Miniband, and the number of contiguous resource units based on Miniband.

These parameters are common parameters, so this embodiment can satisfy most of the application scenarios indicating parameters.

Preferably, the number of downlink subband allocations and/or the number of uplink subband allocations refers to: the number of subbands in the subband division, the downlink frequency partition configuration, and/or the uplink frequency partition configuration refers to the number of frequency partitions in the frequency partition division. And/or the size or proportion of each frequency partition, the downlink frequency partition subband allocation number, and/or the uplink frequency partition subband allocation number refer to the number of subbands in the frequency partition except the frequency partition 0 in the frequency partition, and the downlink continuous Number of resource unit allocations and/or allocation of uplink contiguous resource units The number refers to the number of contiguous resource unit allocations in each frequency partition, and the number of downlink contiguous resource units based on Miniband refers to the number of contiguous resource units based on Miniband in downlink frequency partition 0 and the number of contiguous resource units based on Miniband. It refers to the number of contiguous resource units based on Miniband in the uplink frequency partition 0, where the unit of the number is a sub-band or a micro-band or a physical resource unit.

This embodiment further provides specific content of the number of downlink subband allocations and/or the number of uplink subband allocations, so that this embodiment can be used to indicate parameters having the above contents.

With the technical solution provided by the embodiment of the present invention, the number of bits used by the physical resource mapping indication signaling can be flexibly changed according to the bandwidth used by the system, and the number of transmitted bits is reduced as much as possible without affecting the normal operation of the system. The downlink control overhead is saved, thereby improving the working efficiency of the system.

Various examples of the number of bits indicating the same parameter corresponding to different bandwidths will be described in detail below with reference to specific examples.

In the following description, multiple indication signaling values of parameters (eg, DSAC, USAC, etc.) and physical indications indicated by the indicated signaling values are shown by a plurality of tables (eg, subbands described below) The specific correspondence of the number). It should be understood that, for each table that appears in the following, the correspondence between the indication value of the parameter indication signal and the physical meaning indicated by the value of the indication signaling may be changed according to actual needs, and is not limited to the one shown in the table. Correspondence.

In the table shown below, the case where parameter indication is performed by various methods such as lbit, 2bits, 3bits, and 4bits is specifically given. For example, in the case of using lbit and having two optional values, the indication signaling uses the binary "0" to represent 0 in the table, the binary "1" to represent 1 in the table, and the 2bit to perform parameters. In the case where there are 4 indications and optional values, the indication signaling uses the binary "00" to represent 0 in the table, the binary "01" to represent 1 in the table, and the binary "10" to represent 2 in the table. Use binary "11" to indicate 3 in the table; in the case where 3 bits are used for parameter indication and there are 8 optional values, the indication signaling uses binary "000" to represent 0 in the table, with binary " 00 Γ means 1 in the table, 2 in the table with binary "010", 3 in the table with binary "011", 4 in the table with binary "100", "101" in binary Represents 5 in the table, with the binary "110" for the 6 in the table, the binary "111" for the 7 in the table, and the 4bits for the parameter indication and the optional value of 16 for the indication. Let the binary "0000" be used to represent 0 in the table, and the binary "0001" to represent 1 in the table. The system "0010" represents 2 in the table, the binary "001" indicates 3 in the table, the binary "0100" indicates 4 in the table, and the binary "010Γ indicates 5 in the table, with binary "0110".

In addition, in some cases, because some values are unlikely or infrequent, some parts of the table may be reserved in some cases, as shown in Table 1.9 and Table 3.13, although the n-bit indication may indicate 2 ⁿ combinations, the location to be reserved is filled with the actual value, but some values are of little use, so a part of the value is set to be reserved. This method also applies to other forms of instructional information. Configuration method of downlink subband allocation number

Example 1

FIG. 10 is a schematic diagram of application of signaling DSAC when a resource mapping indication information configuration method according to an embodiment of the present invention uses different numbers of bit indication parameters for a 5 MHz system bandwidth, as shown in FIG. 10, when DS AC values are different (That is, when the number of downlink Subbands indicated by the DSAC is different), the downlink Subband Partitioning process is different. It can be seen that when DSAC takes different values, the way the resources are mapped is different.

The system bandwidth is 5MHz, 10MHz (also 7MHz or 8.75MHz), 20MHz as an example. The configuration of DSAC is divided into three types of bandwidth. The first type is 5MHz, and the second type is 10MHz or 7MHz or 8.75. MHz, the third category is 20MHz.

The first type: when the system bandwidth is 5MHz, the number of bits used to indicate the DSAC parameters is 2bits; for 5MHz, the possible value set of the number of _Subbands is A _DSAC = {0, 1, 2, 3, 4, 5, 6} . 1.1 Describes the correspondence between the value of DSAC and the number of Subbands when the system bandwidth is 5ΜΗζ and the number of bits used by the DSAC is 2 bits. 2bits represents the number of four different Subbands. The number of these four different Subbands is taken from the possible value set of the number of Subbands at 5MHz, A _DSAC , and a total of C ₇ ⁴ = 35 combinations. For example, Table 1.1 takes {0, 1, 2, 3}, and other combinations are no longer - enumerated. It should be noted that n non-repeating elements from m different elements form a subset, regardless of the order of the elements, which is called no-recombination of n from m, and the total number of all possible combinations is used.

Cm" indicates.

Table 1.1

Or: When the system bandwidth is 5MHz, the number of bits used to indicate DSAC parameters is 3bits. 3bits represents 8 different subband numbers, which can represent all the elements in the set A _DSAC . As shown in Table 1.2.

Table 1.2

In some cases, some of the elements in the set A _DSAC may also be represented by 3 bits, and other cases are reserved or used to indicate other conditions, as shown in Table 1.3. Among them, 5 - 7 means that the parameters in the table are the same as the cases indicated by 5, 6, and 7. They are written together to simplify the table, and the other tables below are the same, and will not be repeated later.

Table 1.3

The second type: When the system bandwidth is 7MHz or 8.75MHz or 10MHz, the number of bits used to indicate the DSAC parameters is 3bits;

For 7MHz or 8.75MHz or 10MHz, the possible set of values for the number of Subbands is BDSAC = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12} „ Table 1.4 2 flute The relationship between the DSAC value and the number of Subbands in the case where the system bandwidth is 10 MHz (which may be 7 MHz or 8.75 MHz) and indicates that the number of bits used by the DSAC is 3 bits. 3 bits represents 8 different subband numbers. The number of these different subbands is taken from 10MHz (also 7MHz or 8.75MHz). The possible value set of Subband number is B _DSAC , and a total of C ₁₃ ⁸ = 1287 combinations. For example, Table 1.4 takes {0, 1, 2,3,4,5,6,7}, other combinations than Table 1.4 are not listed.

Table 1.4

Or: When the system bandwidth is 10MHz or 7MHz or 8.75MHz, the number of bits used to indicate DSAC parameters is 4bits. 4bits represents 16 different Subband numbers, these 16 different The number of Subbands is sufficient to represent all elements in the set B _DSAC . As shown in Table 1.5.

Table 1.5

In some cases, some of the elements in the set B _DSAC may also be represented by 4 bits, otherwise reserved or used to indicate other conditions, as shown in Table 1.6.

Table 1.6

Third bandwidth: When the system bandwidth is 20MHz, the number of bits used to indicate the DSAC parameters is

3bits.

For 20MHz, the possible set of values for the number of _Subbands is C _DSAC = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17 , 18, 19, 20, 21, 22, 23, 24} „ Table 1.7 describes the correspondence between the value of DSAC and the number of Subbands when the system bandwidth is 20 MHz and the number of bits used by the DSAC is 3 bits. 3bits represents 8 different subband numbers. The 8 different subband numbers are taken from the possible value set of the Subband number C _{DSAC at} 20MHz, and a total of C ₂₅ ⁸ = 1081575 combinations. For example, Table 1.7 takes {0, 2, 3, 4, 6, 8, 9, 12}, except for Table 1.7, other combinations are not listed.

Table 1.7

3 4 7 12

Or, when the system bandwidth is 20 MHz, the number of bits used to indicate the DSAC parameters is 4 bits. 4bits represents 16 different Subband numbers. The 16 different Subband numbers are taken from the aggregate CDSAC, and a total of C ₂₅ ¹⁶ = 2042975 combinations. For example, Table 1.8 takes {0,1,2,3,4,5,6 , 7, 8, 9, 10, 11, 12, 13, 14, 15}, other combinations than Table 1.8 are not listed.

Table 1.8

Or, when the system bandwidth is 20 MHz, the number of bits used to indicate the DSAC parameters is 5 bits. 5 bits represents 32 different subband numbers, and the number of these 32 different Subbands is sufficient to represent all elements in the set C _DSAC . As shown in Table 1.9.

Table 1.9

In some cases, some of the elements in the set C _DSAC may also be represented by 5 bits, otherwise reserved or used to indicate other conditions, as shown in Table 1.10. Table 1. 10

The number of bits used to indicate the DSAC parameters for each bandwidth can be determined from the above method, but for a plurality of different bandwidths supported by the system, the number of bits used to indicate the parameters is identical or completely different from each other. For example, when the system bandwidth is 5MHz, the number of bits used to indicate DSAC parameters is 3bits; when the system bandwidth is 10MHz (also 7MHz or 8.75MHz), the number of bits used to indicate the parameter is 4bits; when the system bandwidth is 20MHz , indicating that the number of bits used by the parameter is 5 bits; or, when the system bandwidth is 5 MHz, the number of bits used to indicate the DSAC parameter is 2 bits; when the system bandwidth is 10 MHz (also 7 MHz or 8.75 MHz), the parameter is indicated. The number of bits used is 3 bits; when the system bandwidth is 20 MHz, the number of bits used to indicate the parameter is 4 bits; or other combinations.

It should be noted that in this method, even if two different bandwidths use the same number of bits to indicate the DSAC parameters, the corresponding tables may be different. For example, when the system bandwidth is 10MHz (also 7MHz or 8.75MHz), the number of bits used to indicate the parameter is 4bits, but the corresponding table is Table 1.6; when the system bandwidth is 20MHz, the number of bits used by the parameter is indicated. It is 4bits, but the corresponding table is Table 1.8.

Since the system bandwidth is 10MHz (which can be 7MHz or 8.75MHz) and the system bandwidth is 20MHz, the 10MHz (can be 7MHz or 8.75MHz) and 20MHz features can be considered. The system bandwidth can be 10MHz (can be 7MHz). Or 8.75MHz) and the system bandwidth is 20MHz, the same DSAC value and corresponding relationship are used, which makes the device manufacturing simpler, that is, the system bandwidth is 10MHz (can be 7MHz or 8.75MHz) and the system bandwidth is 20MHz. Use the same form. For example, when the system bandwidth is 5MHz, the DSAC is indicated. The number of bits used for the parameter is 2 bits. When the system bandwidth is 10 MHz (also 7 MHz or 8.75 MHz) and 20 MHz, the number of bits used to indicate this parameter is 4 bits.

Table 1.1 describes the mapping between the value of DSAC and the number of subbands when the system bandwidth is 5 MHz and the number of bits used by the DSAC is 2 bits. It is not mentioned here.

When the system bandwidth is 10MHz (also 7MHz or 8.75MHz) and 20MHz, and the number of bits used by the DSAC is 4bits, you can use 20MHz in one of the tables that require 4bits to indicate DSAC, for example, Table 1.8 is used to determine the correspondence between the value of DSAC and the number of Subbands.

Through the above example 1, it can be seen that the system bandwidth is 5MHz, 10MHz (which can be 7MHz or 8.75MHz). In the 20MHz system, the number of bits indicating the DSAC needs 2bits, 3bits, 4bits, or 2bits, 4bits, 4bits respectively. , or 3bits, 4bits, 4bits, or 3bits, 4bits, 5bits, etc., respectively, when the possible value of the DSAC is reduced, the redundant and unnecessary information indications are deleted, and the bit overhead is saved. And to ensure a certain flexibility.

Configuration method of uplink subband allocation number

Example 2

11 is a schematic diagram of a method for configuring a resource mapping indication information according to an embodiment of the present invention, when a different number of bit indication parameters are used for a 5 MHz system bandwidth, as shown in FIG. 11, when the values of USAC are different (ie, When the number of uplink Subbands indicated by USAC is different, the uplink Subband Partitioning process is different. It can be seen that when USAC takes different values, the way the resources are mapped is different.

The system bandwidth is 5MHz, 10MHz (also 7MHz or 8.75MHz), 20MHz as an example, and the three types of bandwidth are divided into the configuration of USAC. The first type is 5MHz, and the second type is 10MHz or 7MHz or 8.75. MHz, the third category is 20MHz.

The first type: When the system bandwidth is 5MHz, the USAC parameter is similar to the DSAC configuration method in Embodiment 1, and the USAC can be represented by 2 or 3bits. The second type: When the system bandwidth is 7MHz or 8.75MHz or 10MHz, the USAC parameter is indicated. Similar to the DSAC configuration method in Embodiment 1, the USAC can be represented by 3 or 4 bits, and the third bandwidth: When the system bandwidth is 20 MHz, the USAC parameter is indicated to be similar to the DSAC configuration method in Embodiment 1, and the USAC can be represented by 4 or 5 bits. . The corresponding table of the above three cases is similar to the table of the example 1, and only the DSAC can be changed to the USAC. For the detailed method, refer to the embodiment 1, which is not repeated here.

The number of bits used to indicate the USAC parameter under each bandwidth can be determined from the above method, but for a plurality of different bandwidths supported by the system, the number of bits used to indicate the parameter is mutually The points are the same or completely different. Because the design methods of USAC and DSAC are similar, the corresponding table is similar to the table of Example 1. Just change the DSAC to USAC. For detailed methods, see Example 1, and no longer .

Since the system bandwidth is 10MHz (which can be 7MHz or 8.75MHz) and the system bandwidth is 20MHz, the 10MHz (which can be 7MHz or 8.75MHz) and 20MHz features can be considered. Because the design methods of USAC and DSAC are similar, corresponding The table is similar to the table in Example 1. Just change the DSAC to USAC. For detailed methods, see Example 1, and no longer - praise.

Through the above example 2, it can be seen that the system bandwidth is 5MHz, 10MHz (which can be 7MHz or 8.75MHz). In the 20MHz system, the number of bits indicating the USAC needs 2bits, 3bits, 4bits, respectively, or 2bits, 4bits, 4bits respectively. , or 3bits, 4bits, 4bits, or 3bits, 4bits, 5bits, etc., respectively, when the possible value of the USAC is reduced, the redundant and unnecessary information indications are deleted, and the bit overhead is saved. And to ensure a certain flexibility.

Downstream frequency partition configuration (DFPC) configuration method

Example 3

The DFPC indicates the size and number of frequency partitions in the downlink subframe. 12 is a schematic diagram of application of signaling DFPC when a different number of bit indication parameters are used for a 10 MHz system bandwidth according to an embodiment of the present invention. As shown in FIG. 12, when the DFPC takes different values, the downlink frequency is shown in FIG. The Partitioning process is different. It can be seen that when DFPC takes different values, the way of resource mapping is different.

The system bandwidth is 5MHz, 7MHz, 8.75MHz, 10MHz and 20MHz as an example, and it is divided into three types of bandwidth to explain the configuration of DFPC, the first type is 5MHz, the second type is 7MHz or 8.75MHz or 10MHz, The third category is 20MHz. Wherein, N _PRU is the number of _PRUs in one subframe. In general, 5MHz, 7MHz, 8.75MHz, 10MHz, and 20MHz correspond to PN _PRU, and another ¹ J is 24, 48, 48, 48, and 96, but the method does not Subject to jt匕F艮. And, in the expression of each frequency partition ratio (FP.: FPi : FP ₂ : FP ₃ ) in the following tables, for the occurrence of N1 : N2: N3 : N4 , where N1 to N4 can represent the actual frequency partition The number can also represent the proportional relationship between the frequency partitions.

The first type: When the system bandwidth is 5MHz, the number of bits used to indicate the DFPC parameter is 2bits. For 5MHz, the set of possible configurations for _DFPC is A _DFPC :

{ (1 frequency partition, frequency partition size is N _PRU ), (3 frequency partitions, each frequency partition size is N _PRU * l/3 ), (4 frequency partitions, and FPS. = Np _RU * 3/24 , FPS ₁ = FPS ₂ = FPS ₃ = NPRU*7/24 ), (4 frequency partitions, and FPSo = Νρκυ*6/24, FPSi = FPS ₂ = FPS ₃ =

NPRU*1/4), (4 frequency partitions, and FPS ₀ = = NPRU*9/24, FPSi = FPS ₂ = FPS ₃ =

NPRU*5/24), (4 frequency partitions, and FPSo = N _PRU *l/2, FPSi = FPS ₂ = FPS ₃ =

NPRU*1/6), (4 frequency partitions, and FPS ₀ = NPRU* 15/24, FPSi = FPS ₂ = FPS ₃ =

NPRU*1/8), (4 frequency partitions, and FPS. = NPRU* 18/24, FPSi = FPS ₂ = FPS ₃ =

NPRU*1/12), (4 frequency partitions, and FPS ₀ = NPRU*21/24, FPSi = FPS ₂ = FPS ₃ =

N _PRU *l/24 ) }.

2bits represents 4 different frequency partition numbers and frequency partition sizes. The 4 different frequency partition numbers and frequency partition sizes are taken from the set A _DFPC , and a total of C ₉ ⁴ = 126 combinations. For example, Table 3.1 describes the correspondence between the value of DFPC and the number of frequency partitions and the size of the frequency partition. FPCT refers to the number of effective frequency partitions, and other combinations are no longer listed.

Form 3.1

Or, when the system bandwidth is 5MHz, the number of bits used to indicate the DFPC parameter is 3 bits. 3bits represents 8 different frequency partition numbers and frequency partition sizes. The 8 different frequency partition numbers and frequency partition sizes are taken from A _DFPC with a total of C ₉ ⁸ = 9 combinations. For example, Table 3.2 describes the correspondence between the value of DFPC and the number of frequency partitions and the size of the frequency partition. Other combinations are no longer listed.

Table 3.2

Or, although 3bits can represent 8 different frequency partition numbers and frequency partition sizes, since some frequency partition sizes are basically not used, you can select the frequently used frequency partition size from A _DFPC to indicate the ratio. 5, 6 or 7 combinations, total C ₉ ⁵ = 126 combinations, C ₉ ⁶ = 84 combinations, C ₉ ⁷ = 36 combinations. For example, as shown in Table 3.3, other combinations are no longer listed.

The 8 different frequency partition numbers and frequency partition sizes are taken from the set B _DFPC , and a total of C ₁₇ ⁸ = 24310 combinations. For example, as shown in Table 3.5, others are no longer - enumerated.

Table 3.12

In some cases, you can join other frequency partition configurations other than the set B _DFPC , as shown in Table 3.13:

Table 3.13

The number of bits used to indicate DFPC parameters for each bandwidth can be determined from the above method, but for different bandwidths, the number of bits used to indicate DFPC parameters is partially identical or completely different. For example, when the system bandwidth is 5MHz, the number of bits used to indicate the DFPC parameter is 3bits; when the system bandwidth is 10MHz (also 7MHz or 8.75MHz), the number of bits used to indicate the parameter is 3bits; when the system bandwidth is 20MHz Indicates that the number of bits used by this parameter is 4 bits; or, when the system bandwidth is 5 MHz, the number of bits used to indicate the DFPC parameter is 2 bits; when the system bandwidth is 10 MHz (also 7 MHz or 8.75 MHz), the parameter is indicated. The number of bits used is 3 bits; when the system bandwidth is 20 MHz, the number of bits used to indicate the parameter is 4 bits; or other combinations.

It should be noted that in the above DFPC configuration method, when two different bandwidths use the same number of bits to indicate DFPC parameters, the corresponding tables may be the same or different. For example, when the system bandwidth is 10MHz (also 7MHz or 8.75MHz), the number of bits used to indicate the parameter is 4bits, but the corresponding table is Table 3.8; when the system bandwidth is 20MHz, the number of bits used by the parameter is indicated. 4bits, but the corresponding table is Table 3.13.

Since the system bandwidth is 10MHz (can be 7MHz or 8.75MHz) and the system bandwidth is

The 20MHz case is similar. You can consider the characteristics of 10MHz (which can be 7MHz or 8.75MHz) and 20MHz. You can use the same DFPC when the system bandwidth is 10MHz (which can be 7MHz or 8.75MHz) and the system bandwidth is 20MHz. Values and correspondences make device manufacturing simpler, ie, the same table is used when the system bandwidth is 10MHz (which can be 7MHz or 8.75MHz) and the system bandwidth is 20MHz. For example, when the system bandwidth is 5 MHz, the number of bits used to indicate the DFPC parameter is 2 bits; and when the system bandwidth is 10 MHz (also 7 MHz or 8.75 MHz) and 20 MHz, the number of bits used to indicate the parameter is 4 bits. Table 3.1 above describes the configuration method in the case where the system bandwidth is 5 MHz and the number of bits used by the DFPC is 2 bits, which is not mentioned here.

When the system bandwidth is 10MHz (also 7MHz or 8.75MHz) and 20MHz, and the number of bits used by the DFPC is 4bits, you can use 20MHz in one of the tables when 4bits is required to indicate DFPC. For example, It is used in Table 3.13.

In addition, it should be pointed out that in the above DFPC configuration method, for each table, the relationship between the value of the DFPC and the meaning indicated by the value of the DFPC can be changed, and each table is an embodiment, as long as one table contains The values of the DFPC values are the same and are considered to be the same table, all within the scope of protection. For example, Table 3.10 and Table 3.14 are both considered to be the same table, because the values of the DFPC contained in the two tables are the same meaning.

Table 3.14

Through the above example 3, it can be seen that the system bandwidth is 5MHz, 10MHz (which can be 7MHz or 8.75MHz). In the 20MHz system, the number of bits indicating the DFPC needs 2bits, 3bits, 4bits, respectively, or 2bits, 4bits, 4bits respectively. , or 3bits, 4bits, 4bits, or 3bits, 4bits, 5bits, etc., or other combinations, when the possible value of DFPC is reduced, redundant and unnecessary information indications are deleted, saving Bit overhead, and guarantees a certain flexibility.

Uplink frequency partition configuration (UFPC) configuration method

Example 4

The UFPC indicates the size and number of frequency partitions in the uplink subframe. FIG. 13 is a schematic diagram of a method for configuring a resource mapping indication information according to an embodiment of the present invention, when a different number of bit indication parameters are used for a 10 MHz system bandwidth, and FIG. 13 is a schematic diagram of the UFPC. The value of the upstream Frequency Partitioning process is different. It can be seen that when UFPC takes different values, the way of resource mapping is different.

The system bandwidth is 5MHz, 7MHz, 8.75MHz, 10MHz and 20MHz as an example, and it is divided into three types of bandwidth to explain the configuration of UFPC, the first type is 5MHz, the second type is 7MHz or 8.75MHz or 10MHz, The third category is 20MHz. among them, ! ^ is the number of PRUs in a sub-frame. In general, 5MHz, 7MHz, 8.75MHz, 10MHz and 20MHz correspond to όN _PRU and ¹ J is 24, 48, 48, 48 and 96, but this method is not subject to jt匕F艮. And, in the expression of each frequency partition ratio (FP.: FPi : FP ₂ : FP ₃ ) in the following tables, for the occurrence of Nl : N2: N3: N4, where N1 to N4 can represent the actual frequency partition The number can also represent the proportional relationship between the frequency partitions.

The first type: When the system bandwidth is 5MHz, the UFPC parameter is similar to the DFPC configuration method in Embodiment 3. The UFPC can be represented by 2 or 3 bits. The second type: When the system bandwidth is 7MHz or 8.75MHz or 10MHz, the UFPC parameter is indicated. Similar to the DFPC configuration method in Embodiment 3, UFPC can be represented by 3 or 4 bits. The third type: When the system bandwidth is 20 MHz, the UFPC parameter is similar to the DFPC configuration method in Embodiment 3. The UFPC can be represented by 3 or 4 bits. . The corresponding table of the above three cases is similar to the table of the embodiment 3, except that the 4 bar DFPC is changed to UFPC, and the detailed method can be referred to the embodiment 3, and the description is no longer repeated.

The number of bits used to indicate UFPC parameters for each bandwidth can be determined from the above method, but for different bandwidths, the number of bits used to indicate UFPC parameters is partially identical or completely different. The UFPC parameter is similar to the DFPC configuration method in Embodiment 3, and the detailed method can be referred to in Embodiment 3, and is not described again here.

It should be pointed out that in the above UFPC configuration method, when two different bandwidths use the same number of bits to indicate UFPC parameters, the corresponding tables may be the same or different. The corresponding table is similar to the table of Embodiment 3, except that the 4 bar DFPC is changed to UFPC. For detailed methods, see Example 3, and the jt匕 is no longer described.

Since the system bandwidth is 10MHz (which can be 7MHz or 8.75MHz) and the system bandwidth is 20MHz, the 10MHz (can be 7MHz or 8.75MHz) and 20MHz features can be considered. The system bandwidth can be 10MHz (can be 7MHz). Or 8.75MHz) and the system bandwidth is 20MHz, the same UFPC value and corresponding relationship are used, which makes the device manufacturing simpler, that is, the system bandwidth is 10MHz (can be 7MHz or 8.75MHz) and the system bandwidth is 20MHz. Use the same form.

Through the above example 4, it can be seen that the system bandwidth is 5MHz, 10MHz (may be 7MHz or 8.75MHz), and in the 20MHz system, the number of bits indicating the UFPC needs 2bits, respectively. 3bits, 4bits, or 2bits, 4bits, 4bits, or 3bits, 4bits, 4bits, or 3bits, 4bits, 5bits, etc., or other combinations, if the possible value of UFPC is reduced, delete Redundant and unnecessary information indication saves bit overhead and guarantees a certain flexibility.

Table 5.7

The number of bits used to indicate DFPSC parameters for each bandwidth can be determined from the above method, but for different bandwidths, the number of bits used to indicate DFPSC parameters is partially identical or completely different. Case,

When the system bandwidth is 5MHz, the number of bits used to indicate the DFPSC parameters is lbits; when the system bandwidth is 10MHz (also 7MHz or 8.75MHz), the number of bits used to indicate the parameter is 2bits; when the system bandwidth is 20MHz, the indication is The number of bits used in this parameter is 3 bits; or, when the system bandwidth is 5 MHz, the number of bits used to indicate the DFPSC parameter is 1 bit; when the system bandwidth is 10 MHz (also 7 MHz or 8.75 MHz), the parameter is used to indicate the The number of bits is 2 bits; when the system bandwidth is 20 MHz, the number of bits used to indicate the parameter is 2 bits; or other combinations.

It should be noted that in the above DFPSC configuration method, when two different bandwidths use the same number of bits to indicate DFPSC parameters, the corresponding tables may be the same or different. For example, when the system bandwidth is 10MHz (also 7MHz or 8.75MHz), the number of bits used to indicate the parameter is 3bits, but the corresponding table is Table 5.4; when the system bandwidth is 20MHz, the number of bits used by the parameter is indicated. It is 3bits, but the corresponding table is Table 5.6.

The third category: When the system bandwidth is 20MHz, the number of bits used to indicate the DCAS _SB1 parameter is

DCAS _SBi can use any combination. For example, as shown in Table 7.7, other similar, no longer - enumerated.

Table 7.7

Or, when the system bandwidth is 20MHz, the number of bits used to indicate the DCAS _SB1 parameter is 5bits. 5bits represents 32 different numbers, and these 32 different numbers can represent all the values in set C. For example, Table 7.8 shows.

Table 7.8

The number of bits used to indicate the DCAS _SB1 parameter under each bandwidth can be determined from the above method, but for different bandwidths, the number of bits used to indicate the DCAS _SB1 parameter is partially identical or completely different from each other. For example, when the system bandwidth is 5MHz, the number of bits used to indicate the DCAS _SB1 parameter is _3bits ; when the system bandwidth is 10MHz (also 7MHz or 8.75MHz), the number of bits used to indicate the parameter is 4bits; the system bandwidth is 20MHz. The number of bits used to indicate the parameter is 5 bits; or, when the system bandwidth is 5 MHz, the number of bits used to indicate the DCAS _SBi parameter is 1 bit; when the system bandwidth is 10 MHz (also 7 MHz or 8.75 MHz), the indication is The number of bits used by the parameter is 2 bits; when the system bandwidth is 20 MHz, the number of bits used to indicate the parameter is 3 bits; or other combinations.

It should be noted that in the above DCAS _SB configuration method, when two different bandwidths use the same number of bits to indicate the DCAS _SB1 parameter, the corresponding tables may be the same or different. For example, when the system bandwidth is 10MHz (also 7MHz or 8.75MHz), the number of bits used to indicate the parameter is 4bits, but the corresponding table is Table 7.5; when the system bandwidth is 20MHz, the number of bits used by the parameter is indicated. It is 4bits, but the corresponding table is Table 7.7.

The same table means: Since the system bandwidth is 1 OMHz (which can be 7MHz or 8.75MHz) and the system bandwidth is 20MHz, the similarity can be considered. The 10MHz (can be 7MHz or 8.75MHz) and 20MHz features can be unified. Bandwidth is 10MHz (can be 7MHz Or 8.75MHz) and the system bandwidth is 20MHz, the same DCAS _SBi value and corresponding relationship, that is, the system bandwidth is 10MHz (can be 7MHz or 8.75MHz) and the system bandwidth is 20MHz, use the same table, for example , can be used in Table 7.7, or in accordance with the 20MHz configuration method. Or, generate it as follows:

Table 7.9

In addition, 5MHz can be used with 2MHz or 3bit for 10MHz (also 7MHz or 8.75MHz).

Further, to be noted: In the configuration above DCAS _SBl, the relationship between the intermediate meaning indicated for each table value with DCAS _SBl the DCAS _SBl is to be changed, each form are one embodiment, as long as a The DCAS _SB values included in the table are the same meanings and are considered to be the same table, all within the scope of protection.

Through the above example 7, it can be seen that the system bandwidth is 5MHz, 10MHz (which can be 7MHz or 8.75MHz). In the 20MHz system, the number of bits indicating DCAS _SBi needs 2bits, _{3bits, 3bits} , or 2bits, 3bits, respectively. 4bits, or 3bits, 4bits, 4bits, or 3bits, 4bits, 5bits or other combinations respectively, when the possible value of DCAS _SBi is reduced, the redundancy and unnecessary information indication are deleted, saving Bit overhead, and guarantees a certain flexibility.

The uplink CRU/DRU Allocation process is different. It can be seen that when UCAS _SB takes different values, the way of resource mapping is different.

The second type: When the system bandwidth is 7MHz or 8.75MHz or 10MHz, The UCAS _SBi parameter is similar to the DCAS _SB configuration method in Embodiment 7, and UCAS _SB can be represented by 2, 3 or 4 bits. The third type: when the system bandwidth is 20 MHz, the UCAS _SBi parameter is indicated and the DCAS _SB configuration in Embodiment 7 is specified. The method is similar, and UCAS _SB can be represented by 3, 4 or 5 bits. The foregoing 3 conditions corresponding tables and table also similar to Example 7, except the DCAS _SB UCAS _SB can be changed, reference may be made in detail the method of Example 7, which is not detailed herein.

The number of bits used to indicate the UCAS _SB1 parameter under each bandwidth can be determined from the above method, but for different bandwidths, the number of bits used to indicate the UCAS _SB1 parameter is partially identical or completely different from each other. The UCAS _SB parameters are similar to the DCAS _SB configuration method in Embodiment 7, and the detailed method can be seen in Embodiment 7, and is not described again here.

For the detailed method, refer to the embodiment 7, which is not repeated here.

The same table means: Since the system bandwidth is 10MHz (can be 7MHz or 8.75MHz) and the system bandwidth is 20MHz, the similarity can be considered to be unified by 10MHz (can be 7MHz or 8.75MHz) and 20MHz, and the system bandwidth can be The value of the same UCAS _SBi is 10MHz (which can be 7MHz or 8.75MHz) and the system bandwidth is 20MHz, that is, the system bandwidth is 10MHz (can be 7MHz or 8.75MHz) and the system bandwidth is 20MHz. The same table is used, and the corresponding table is similar to the table of the embodiment 7, except that the DCASSB is changed to the UCAS _SB .

In the 20MHz system, the number of bits indicating the UCAS _SBI needs 3bits, 4bits, 5bits, or lbits, 2bits, respectively. 3bits, or 3bits, 4bits, 4bits, or 3bits, 3bits, 4bits, or other combinations respectively. When the possible value of UCAS _SBI is reduced, redundant and unnecessary information indications are deleted, saving Bit overhead, and guarantees a certain flexibility.
