Description

Resource allocation method and device

Technical Field

The present invention relates to the field of communications, and in particular, to a resource allocation method and apparatus.

Background

With the development of communication technology, in a WLAN system (e.g., 802.11ax), frequency domain resources of different bandwidths can be divided into at least one resource block, and scheduling information corresponding to the divided resource block is indicated (e.g., indicating on which resource block MU-MIMO (Multi-User Multiple-Input Multiple-Output) transmission can be performed). The 802.11ax is an 802.11 wireless local area network communication standard, which transmits through a 5G frequency band, and is a subsequent upgrade of 802.11 ac. MU-MIMO is a technique for a router to communicate with multiple devices simultaneously.

The existing resource allocation method adopts a bitmap indication mode based on resource blocks to inform a receiving end of a resource allocation mode on the current transmission bandwidth. Specifically, the bitmap indication mode adopts a continuous "1" or "0" sequence to indicate that the resource blocks allocated to the same station are allocated to another station by means of hopping from "1" to "0" or from "0" to "1". Therefore, the number of bits used to indicate the resource allocation pattern over the current transmission bandwidth is equal to the number of resource blocks over the current transmission bandwidth. For example, as shown in fig. 1, there are 9 1 × 26 resource blocks in a 20mhz bandwidth, then the number of bits used to indicate the resource allocation pattern over the current transmission bandwidth is equal to 9 bits. If the receiving end receives a bitmap indication sequence of "110010000", it can be known that the 1 st and 2 nd resource blocks are allocated to site 1, the 3 rd and 4 th resource blocks are allocated to site 2, the 5 th resource block is allocated to site 3, and the remaining 4 resource blocks are allocated to site 4. It should be noted that the resource blocks into which the bitmap indication sequence indication received by the receiving end is actually divided correspond to the subsequent station information. For example, the bitmap indication sequence after the resource block is divided in fig. 1 is "110010000", station 1 information, station 2 information, station 3 information, and station 4 information. Each site information contains a site identifier, which is used to identify the site and is the identity of the site.

However, when the bandwidth resources are divided by using the above resource allocation method, the number of bits used for indicating the resource allocation mode on the current transmission bandwidth is equal to the number of resource blocks on the current transmission bandwidth, rather than the number of resource blocks actually divided by the current transmission bandwidth. For a bandwidth of 80mhz or a bandwidth of 160mhz, the number of resource blocks that may be divided is large, and thus the number of bits for indicating the resource allocation pattern on the current transmission bandwidth is also increased.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The embodiment of the invention is applied to a WLAN system, taking 802.11ax as an example, and the packet structure of 802.11ax is shown in fig. 2, wherein the preamble part includes an L-preamble (Legacy preamble) and an HE (High efficiency) preamble adjacent to the L-preamble. The L-preamble includes L-STF (short Training Field), L-LTF (Long Training Field), and L-SIG (signaling Field). The HE preamble includes RL-SIG (Rdotted Legacy Signaling Field), HE-SIGA (High efficiency Signal Field A), HE-SIGB (High efficiency Signal Field B), HE-STF (High efficiency short Training Field), and HE-LTF (High efficiency Long Training Field). Also, the packet structure of the WLAN system may further include DATA (DATA field).

HE-SIGA and HE-SIGB are broadcast to all users to carry signaling information in the 802.11ax packet structure. As shown in fig. 3, the HE-SIG-B includes common information parameters and various scheduled user station information. The public information parameter includes a resource allocation indication, and the scheduled user station information includes a corresponding station identifier. The public information parameters optionally further include a guard interval adopted for data transmission, OFMDA (Orthogonal Frequency division multiple Access)/MU-MIMO indication, HE-LTF number and mode, and may further include parameters such as uplink/downlink indication, presence or absence of a conventional HE-SIGB, and the like. The user station information may also include parameters such as the number of spatial streams of the station, the MCS (Modulation and Coding Scheme, Modulation and Coding strategy) used for data transmission, the Coding type, whether to use the time-space-time code indication, whether to use the beamforming technique indication, and the like. In addition, part of the public information parameters can be carried in the HE-SIGA.

In the WLAN system, the division of the resource block size is one resource unit with 26 subcarriers. As shown in fig. 4, taking a bandwidth of 20mhz as an example, the number of discrete fourier transform/inverse discrete fourier transform points in the data symbol portion in the WLAN system is 256, that is, there are 256 subcarriers, where subcarriers-1, 0, 1 are DC (Direct current component), and left subcarrier-122 to subcarrier-2 and right subcarrier-2 to subcarrier 122 are used for carrying data information, that is, there are 242 subcarriers for carrying data information. Sub-carrier-128 to sub-carrier-123 and sub-carrier 123 to sub-carrier 128 are guard bands. Thus, the 242 subcarriers normally used to carry data information are divided into 9 sub-resource blocks, each sub-resource block comprising 26 subcarriers, the remaining 8 unused subcarriers. And, the sub-resource block located at the center of the bandwidth spans DC (i.e., includes sub-carriers-1, 0, 1), the method of the embodiment of the present invention mainly involves the allocation of 242 sub-carriers for carrying data information.

The types of resource blocks that can be included for frequency domain resources of different bandwidths are different. In particular, the wireless local area network follows a next generation protocol in which resource block locations, which may be partitioned, for various frequency domain resources to be allocated (20MHz, 40MHz, 80MHz, or 160MHz) are agreed.

Taking the frequency domain resource of the 20MHz bandwidth as an example, the resource blocks that may be divided into the frequency domain resource of the 20MHz bandwidth are 1 × 26 resource blocks, 2 × 26 resource blocks, 4 × 26 resource blocks or 242 resource blocks, where 1 × 26 resource block represents that 26 subcarriers are one resource block, 2 × 26 resource block represents that 52 subcarriers are one resource block, 4 × 26 resource block represents that 106 subcarriers are one resource block, and 242 resource blocks represent that 242 subcarriers are one resource block. A frequency domain resource with 20MHz bandwidth can be formed by combining the above resource blocks.

Similarly, taking the frequency domain resource of the 40MHz bandwidth as an example, the frequency domain resource of the 40MHz bandwidth may be divided into 1 × 26 resource blocks, 2 × 26 resource blocks, 4 × 26 resource blocks, 242 resource blocks, or a combination of one or more resource blocks of 2 × 242 resource blocks. The frequency domain resources of the 80MHz bandwidth may be divided into resource blocks of 1 × 26 resource blocks, 2 × 26 resource blocks, 4 × 26 resource blocks, 242 resource blocks, 2 × 242 resource blocks, or a combination of one or more of 996 resource blocks. The frequency domain resources of the 160MHz bandwidth may be divided into 1 × 26 resource blocks, 2 × 26 resource blocks, 4 × 26 resource blocks, 242 resource blocks, 2 × 242 resource blocks, 996 resource blocks, or a combination of one or more of 2 × 996 resource blocks.

Based on the description of the above embodiment, the sending end can generate resource scheduling information including a resource allocation bit sequence, where the resource allocation bit sequence indicating that the frequency domain resource of each 20MHz bandwidth is divided only needs 8 bits or less, and compared with the conventional bitmap indication manner based on resource blocks (the division of the frequency domain resource of each 20MHz bandwidth needs 9 bits to indicate), signaling overhead is reduced.

Example 3

The embodiment of the invention provides a resource allocation method, which comprises the following steps that firstly, the positions of possibly divided resource blocks aiming at various frequency domain resources to be allocated are appointed in a next generation protocol:

one, frequency domain resource for 20MHz bandwidth

Optionally, the resource block position where the frequency domain resource to be allocated may be divided includes a default position, and the resource block corresponding to the default position is a resource block that is agreed in the next generation protocol and is not indicated by the bit sequence. Alternatively, 1 bit may be used to indicate whether the resource block of the default position is allocated to the user.

Specifically, as shown in fig. 7, the frequency domain resources of the 20MHz bandwidth may include a default resource block located at the center (i.e., a resource block located at a default position), and the default resource block may be a 1 × 26 type of resource block, i.e., a resource block spanning DC (subcarrier-1, 0, 1) and including 26 subcarriers. The default resource block is present by default in the communication system, and is allocated independently, that is, in each resource to be allocated in 20MHz bandwidth, a default resource block of 1 × 26 type is divided at its center position, and the default resource block is allocated independently to a receiving end, and the receiving end to which the default resource block is allocated may be the same as or different from the receiving end to which the resource block adjacent to the left side or the right side of the default resource block is allocated, which is not limited in the present invention. For the frequency domain resource of 20MHz bandwidth, the receiving end to which the default resource block is allocated is the same as the receiving end to which the resource block adjacent to the left or right side of the default resource block is allocated, which indicates that the frequency domain resource of 20MHz bandwidth is allocated to only one user. Otherwise, the receiving end to which the default resource block is allocated is different from the receiving end to which the resource block adjacent to the left side or the right side of the default resource block is allocated.

In addition to the default resource block located at the default position, the frequency domain resources of the 20MHz bandwidth further include the following four types of resource blocks located on the left side or the right side of the default resource block in the center of the 20MHz frequency domain resources, respectively, that is:

1 × 26 resource blocks, the smallest resource block that may be divided among frequency domain resources of 20MHz bandwidth, means that one resource block is composed of one sub-resource block (i.e., 26 subcarriers).

2 × 26 resource blocks, meaning that one resource block is composed of two sub-resource blocks (i.e., 2 × 26 subcarriers).

4 × 26 resource blocks, meaning that one resource block is composed of four sub-resource blocks (i.e., 4 × 26 subcarriers).

242 resource blocks, the largest resource block that may be divided among frequency domain resources of 20MHz bandwidth, means that one resource block is composed of 242 subcarriers.

Wherein, the 4 × 26 resource block includes 106 subcarriers, that is, includes 102 data subcarriers and 4 pilot subcarriers, and in the following description of the present invention, descriptions of the same or similar cases are omitted to avoid redundancy.

As shown in fig. 8, for a simple description of resource block locations that may be partitioned, the frequency domain resources of the 20MHz bandwidth may be partitioned into four layers:

the first layer is a distribution diagram of 1 × 26 resource blocks and default resource blocks (i.e., 1 × 26 resource blocks located at the center of frequency domain resources of 20MHz bandwidth), and there are 41 × 26 resource blocks, i.e., resource blocks located at resource block positions #7 to #10 and positions #11 to #14 shown in fig. 8, on the left and right sides of the default resource block located at the center.

The second layer is a distribution diagram of 2 × 26 resource blocks and default resource blocks (i.e., 1 × 26 resource blocks located at the center of the frequency domain resource of the 20MHz bandwidth), and there are 2 × 26 resource blocks, i.e., resource blocks located at positions #1 to #4 shown in fig. 8, on the left and right sides of the default resource block located at the center.

The third layer is a distribution diagram of 4 × 26 resource blocks and default resource blocks (i.e., 1 × 26 resource blocks located at the center of the frequency domain resource of the 20MHz bandwidth), and there are 14 × 26 resource blocks, i.e., resource blocks located at position #5 and position #6 shown in fig. 8, on the left and right sides of the default resource block located at the center.

The fourth layer is 242 resource blocks. The 242 resource blocks contain the subcarriers in which the aforementioned centers of symmetry are located as shown in fig. 8.

Here, for example, the frequency domain resource of the 20MHz bandwidth includes 242 subcarriers, and may be divided into any resource blocks in the first to third layers in fig. 8, the divided resource blocks are allocated to a plurality of users, and each user can allocate only one of the divided resource blocks.

Or, for example, the frequency domain resource spectrum of the 20MHz bandwidth may be divided into resource blocks in the fourth layer, in this case, the frequency domain resource of the 20MHz bandwidth is allocated to one user, and the resource allocation condition may be indicated by bandwidth indication information and a single user transmission indication bit described later.

Further, for example, the frequency domain resource spectrum of the 20MHz bandwidth may be divided into resource blocks in the fourth layer, in this case, the frequency domain resource of the 20MHz bandwidth is allocated to a plurality of users for MU-MIMO transmission, and the resource allocation may be indicated by bandwidth indication information and a multi-user transmission indication bit, which will be described later.

The resource allocation method provided by the embodiment of the invention mainly relates to the situation that the frequency domain resource with the bandwidth of 20MHz is formed by combining any resource blocks from the first layer to the third layer and is allocated to a plurality of users.

Specifically, the combination of the frequency domain resources of the 20MHz bandwidth from any resource block in the first layer to the third layer refers to the combination from any resource block in the first layer to the third layer in fig. 8, and the sum of the sizes of all the resource blocks is 20MHz, as shown by the shaded portion in fig. 9 or fig. 10.

For example, fig. 11 shows a resource allocation method for frequency domain resources of 20MHz bandwidth, and as shown in fig. 11, the frequency domain resources (in order from left to right in fig. 11) are divided into two 2 × 26 resource blocks (i.e., resource block #1 and resource block #2 in fig. 10), one 1 × 26 resource block (i.e., resource block #0 in fig. 10, which is a default resource block), and one 4 × 26 resource block (i.e., resource block #3 in fig. 10).

For another example, fig. 12 shows another resource allocation method for frequency domain resources with a bandwidth of 20MHz, and as shown in fig. 12, the frequency domain resources (in order from left to right in fig. 12) are divided into one 2 × 26 resource block (i.e., resource block #1 in fig. 10), three 1 × 26 resource blocks (i.e., resource block #9, resource block #10, and resource block #11 in fig. 10, where resource block #11 is a default resource block), and 14 × 26 resource block (i.e., resource block #6 in fig. 10).

Optionally, the frequency domain resource to be allocated includes a center of symmetry.

Specifically, as shown in fig. 10, the frequency domain resource of the 20MHz bandwidth includes a resource block located at the center (i.e., the resource block at the default position), and the positions of the resource blocks on both sides of the resource block located at the center are symmetrically distributed, that is, the resource block located at the center can be taken as the symmetric center of the frequency domain resource of the 20MHz bandwidth.

Second, frequency domain resource for 40MHz bandwidth

The frequency domain resources with the bandwidth of 40MHz can be regarded as being composed of two frequency domain resources with the bandwidth of 20MHz, correspondingly, each frequency domain resource with the bandwidth of 20MHz can include a default resource block (that is, a resource block located at a default position) located in the center of the frequency domain resources with the bandwidth of 20MHz, and the configuration and allocation manner of the default resource blocks (two in total) in the frequency domain resources with the bandwidth of 40MHz are similar to those of the default resource blocks in the frequency domain resources with the bandwidth of 20MHz, and here, for avoiding redundant description, detailed description thereof is omitted.

Optionally, 2 bits may be used to respectively indicate whether resource blocks of 2 default positions of the bandwidth are allocated to users for use. In addition to the default resource blocks located at the default positions, the frequency domain resources with the bandwidth of 40MHz also include the following five types of resource blocks located on the left side or the right side of the center frequency point of the frequency domain resources with the bandwidth of 40MHz, that is:

1 × 26 resource blocks, the smallest resource block that may be divided among frequency domain resources of 40MHz bandwidth, means that one resource block is composed of one sub-resource block (i.e., 26 subcarriers).

242 resource blocks, meaning that one resource block is composed of 242 subcarriers.

2 × 242 resource blocks, the largest resource block that may be divided among frequency domain resources of a 40MHz bandwidth, means that one resource block is composed of 2 × 242 subcarriers.

As shown in fig. 13, for a simple description of resource block locations that may be partitioned, frequency domain resources of a 40MHz bandwidth may be partitioned into five layers:

the first layer is a distribution diagram of 1 × 26 resource blocks and default resource blocks (i.e., 1 × 26 resource blocks located at the center of each frequency domain resource with 20MHz bandwidth), and there are 41 × 26 resource blocks on the left and right sides of each default resource block located at the center, where the distribution of 81 × 26 resource blocks in each frequency domain resource with 20MHz bandwidth is similar to the distribution of 1 × 26 resource blocks shown in the first layer in fig. 10, and here, detailed descriptions thereof are omitted to avoid redundancy.

The second layer is a distribution diagram of 2 × 26 resource blocks and default resource blocks (i.e., 1 × 26 resource blocks each located at the center of the frequency domain resource of the 20MHz bandwidth), and there are 2 × 26 resource blocks (e.g., position # E and position # F in fig. 13) on the left and right sides of the default resource block located at each center, where the distribution of 42 × 26 resource blocks in each 20MHz bandwidth is similar to the distribution of 2 × 26 resource blocks shown in the second layer in fig. 10, and here, detailed descriptions thereof are omitted to avoid redundant description.

The third layer is a distribution diagram of 4 × 26 resource blocks and default resource blocks (i.e., 1 × 26 resource blocks located at the center of the frequency domain resource of each 20MHz bandwidth), and there are 14 × 26 resource blocks (e.g., position # C and position # D in fig. 13) on the left and right sides of the default resource block located at each center, where the distribution of 4 × 26 resource blocks in each 20MHz bandwidth is similar to the distribution of 4 × 26 resource blocks shown in the third layer in fig. 10, and thus, detailed descriptions thereof are omitted here for avoiding redundancy.

The fourth layer is a 242-resource block distribution diagram, and there are 1 242 resource blocks, that is, resource blocks located at position # a and position # B shown in fig. 13, on the left and right sides of the center frequency point (that is, subcarrier 0) of the frequency domain resources located in the 40MHz bandwidth.

The fifth layer is a 2x 242 resource block distribution diagram.

Here, for example, the frequency domain resource of the 40MHz bandwidth includes 484 subcarriers, and may be divided into any resource blocks in the first to fourth layers in fig. 13, the divided resource blocks are allocated to a plurality of users, and each user can allocate only one of the divided resource blocks.

Or, for example, the frequency domain resource spectrum of the 40MHz bandwidth may be divided into resource blocks in the fifth layer, in this case, the frequency domain resource of the 40MHz bandwidth is allocated to one user, and the resource allocation condition may be indicated by bandwidth indication information and a single-user transmission indication bit described later.

Further, for example, the frequency domain resource spectrum of the 40MHz bandwidth may be divided into resource blocks in the fifth layer, in this case, the frequency domain resource of the 40MHz bandwidth is allocated to a plurality of users for MU-MIMO transmission, and the resource allocation condition may be indicated by bandwidth indication information and a multi-user transmission indication bit, which will be described later.

The resource allocation method provided by the embodiment of the invention mainly relates to the condition that the frequency domain resource of the 40MHz bandwidth is combined by any resource block in the first layer to the fourth layer and is allocated to a plurality of users.

Specifically, the combination of the frequency domain resources of the 40MHz bandwidth by any resource block in the first layer to the fourth layer refers to the combination by any resource block in the first layer to the fourth layer in fig. 13, and the sum of the sizes of all resource blocks is 40MHz, as shown by the shaded portion in fig. 14 or fig. 15.

For example, fig. 16 shows a resource allocation method for frequency domain resources of 40MHz bandwidth, and as shown in fig. 16, the frequency domain resources (in order from left to right in fig. 16) are divided into two 2 × 26 resource blocks (i.e., resource block # E and resource block # F in fig. 13), one 1 × 26 resource block (i.e., resource block #0 ", which is a default resource block), one 4 × 26 resource block (i.e., resource block # D in fig. 13), and one 242 resource block (i.e., resource block # B in fig. 13).

Specifically, as shown in fig. 13, the resource blocks on both sides of the center frequency point of the frequency domain resource with the bandwidth of 40MHz are symmetrically distributed, that is, the center frequency point can be used as the symmetric center of the frequency domain resource with the bandwidth of 40 MHz.

Frequency domain resource for 80MHz bandwidth

Optionally, the resource block position where the frequency domain resource to be allocated may be divided includes a default position, and the resource block corresponding to the default position is a resource block that is agreed in the next generation protocol and is not indicated by the bit sequence.

Alternatively, 5 bits may be used to respectively indicate whether resource blocks of 5 default positions under the bandwidth are allocated to the user for use.

Specifically, as shown in fig. 17, the frequency domain resources of the 80MHz bandwidth may include a default resource block located at the center (i.e., a resource block located at a default position), and the default resource block may be 1 × 26 resource blocks, i.e., a resource block spanning DC (subcarrier-1, 0, 1) and including 26 subcarriers. The default resource block is present by default in the communication system, and is allocated independently, that is, in each resource to be allocated in the 80MHz bandwidth, a default resource block with the size of 1 × 26 is divided at the center position of the resource, and the default resource block is allocated independently to a receiving end, and the receiving end to which the default resource block is allocated may be the same as or different from the receiving end to which the resource block adjacent to the left side or the right side of the default resource block is allocated, which is not particularly limited in the present invention. For the frequency domain resource of the 80MHz bandwidth, the receiving end to which the default resource block is allocated is the same as the receiving end to which the resource block adjacent to the left side or the right side of the default resource block is allocated, which indicates that the frequency domain resource of the 80MHz bandwidth is allocated to only one user. Otherwise, the receiving end to which the default resource block is allocated is different from the receiving end to which the resource block adjacent to the left side or the right side of the default resource block is allocated.

And, the frequency domain resources of the 80MHz bandwidth can be regarded as being composed of two frequency domain resources of the 40MHz bandwidth and one default resource block located at the symmetrical center, and each frequency domain resource of the 40MHz bandwidth can be regarded as being composed of two frequency domain resources of the 20MHz bandwidth, and accordingly, each frequency domain resource of the 20MHz bandwidth can include the default resource block located at the center of the frequency domain resource of the 20MHz bandwidth (i.e., the resource block located at the default position).

In addition to the default resource blocks located at the default positions, the frequency domain resources of the 80MHz bandwidth further include the following six types of resource blocks located on the left side or the right side of the default resource blocks in the center of the frequency domain resources of the 80MHz bandwidth, respectively, that is:

1 × 26 resource blocks, the smallest resource block that may be divided among frequency domain resources of 80MHz bandwidth, means that one resource block is composed of one sub-resource block (i.e., 26 subcarriers).

2 × 242 resource blocks, meaning that one resource block is composed of 2 × 242 subcarriers.

996 resource block, the largest resource block that may be divided among frequency domain resources of 80MHz bandwidth, means that one resource block is composed of 996 subcarriers.

As shown in fig. 17, for a simple description of resource block locations that may be divided, frequency domain resources of an 80MHz bandwidth may be divided into six layers:

the first layer is a distribution diagram of 1 × 26 resource blocks and default resource blocks (i.e., 1 × 26 resource blocks located at the center of each frequency domain resource of 20MHz bandwidth and 1 × 26 resource blocks located at the center of 80MHz bandwidth), and there are 41 × 26 resource blocks on the left and right sides of the default resource blocks at the center of each frequency domain resource of 20MHz bandwidth, respectively, where the distribution of 81 × 26 resource blocks in each frequency domain resource of 20MHz bandwidth is similar to the distribution of 1 × 26 resource blocks shown in the first layer in fig. 8, and here, detailed descriptions thereof are omitted to avoid redundant description.

The second layer is a distribution diagram of 2 × 26 resource blocks and default resource blocks (i.e., each of 1 × 26 resource blocks located at the center of the frequency domain resource with the 20MHz bandwidth and 1 × 26 resource blocks located at the center of the frequency domain resource with the 80MHz bandwidth), and 2 × 26 resource blocks are respectively located on the left and right sides of the default resource block at the center of the frequency domain resource with the 20MHz bandwidth, where the distribution of 42 × 26 resource blocks in each 20MHz bandwidth is similar to the distribution of 2 × 26 resource blocks shown in the second layer in fig. 8, and here, detailed descriptions thereof are omitted to avoid redundancy.

The third layer is a distribution diagram of 4 × 26 resource blocks and default resource blocks (i.e., 1 × 26 resource blocks located at the center of each frequency domain resource with a bandwidth of 20MHz and 1 × 26 resource blocks located at the center of each frequency domain resource with a bandwidth of 80 MHz), and there are 14 × 26 resource blocks on the left and right sides of the default resource blocks located at the center of each frequency domain resource with a bandwidth of 20MHz, where the distribution of 4 × 26 resource blocks in each frequency domain with a bandwidth of 20MHz is similar to the distribution of 4 × 26 resource blocks shown in the third layer in fig. 8, and a detailed description thereof is omitted here to avoid redundancy.

The fourth layer is a 242 resource block distribution diagram and a default resource block (i.e., 1 × 26 resource blocks located at the center of the frequency domain resource with the bandwidth of 80 MHz), and there are 1 242 resource blocks on the left and right sides of the center frequency point of the frequency domain resource with each bandwidth of 40MHz, i.e., the resource blocks located at the position # c and the position # d shown in fig. 17, where the distribution of the resource blocks of 242 in the frequency domain resource with each bandwidth of 40MHz is similar to the distribution of the resource blocks of 242 shown in the fourth layer in fig. 13, and a detailed description thereof is omitted here to avoid redundant description.

The fifth layer is a distribution diagram of 2 × 242 resource blocks and a distribution diagram of default resource blocks (i.e., 1 × 26 resource blocks located at the center of the frequency domain resource with the bandwidth of 80 MHz), and there are 1 242 resource blocks on the left and right sides of the default resource block located at the center of the frequency domain resource with the bandwidth of 80MHz, that is, resource blocks located at positions # a and # b shown in fig. 17, where the distribution of 242 resource blocks in the frequency domain resource with each bandwidth of 40MHz is similar to the distribution of 242 resource blocks shown at the fifth layer in fig. 13, and here, detailed descriptions thereof are omitted to avoid redundancy.

The sixth layer is a 996 resource block profile.

Here, for example, the frequency domain resource of the 80MHz bandwidth includes 996 sub-carriers, and may be divided into any resource blocks in the first layer to the fifth layer in fig. 17, the divided resource blocks are allocated to a plurality of users, and each user can allocate only one of the divided resource blocks.

Or, for example, the frequency domain resource spectrum of the 80MHz bandwidth may be divided into resource blocks in the sixth layer, in this case, the frequency domain resource of the 80MHz bandwidth is allocated to one user, and the resource allocation condition may be indicated by bandwidth indication information and a single-user transmission indication bit described later.

Further, for example, the frequency domain resource spectrum of the 80MHz bandwidth may be divided into resource blocks in the sixth layer, in this case, the frequency domain resource of the 80MHz bandwidth is allocated to multiple users for MU-MIMO transmission, and the resource allocation condition may be indicated by bandwidth indication information and multi-user transmission indication bits, which will be described later.

The resource allocation method provided by the embodiment of the invention mainly relates to the situation that frequency domain resources with 80MHz bandwidth are combined by any resource blocks in the first layer to the fifth layer and are allocated to a plurality of users.

Specifically, the combination of the frequency domain resources of the 80MHz bandwidth from any resource block in the first layer to the fifth layer refers to the combination of any resource blocks in the first layer to the fifth layer in fig. 17, and the sum of the sizes of all the resource blocks is 80MHz, as shown by the shaded portion in fig. 18 or fig. 19.

For example, fig. 20 shows a resource allocation method for frequency domain resources with 80MHz bandwidth, and as shown in fig. 20, the frequency domain resources (in order from left to right in fig. 20) are divided into one 4 × 26 resource block, one 1 × 26 resource block (which is the default resource block), one 4 × 26 resource block, one 242 resource block, one 1 × 26 resource block (which is the default resource block), and one 2 × 242 resource block (which is the resource block # 4').

Specifically, as shown in fig. 17, the frequency domain resource of the 80MHz bandwidth includes a resource block located at the center (i.e., the resource block at the default position), and the positions of the resource blocks on both sides of the resource block located at the center are symmetrically distributed, that is, the resource block located at the center can be taken as the center of symmetry of the frequency domain resource of the 80MHz bandwidth.

Fourthly, for frequency domain resources of 160MHz bandwidth

The frequency domain resources of the 160MHz bandwidth may be regarded as being composed of two frequency domain resources of the 80MHz bandwidth, and accordingly, each frequency domain resource of the 80MHz bandwidth may include a default resource block (i.e., a resource block located at a default position) located at the center of the frequency domain resources of the 80MHz bandwidth, and each frequency domain resource of the 20MHz bandwidth of the frequency domain resources of the 160MHz bandwidth may include a default resource block (i.e., a resource block located at a default position) located at the center of the frequency domain resources of the 20MHz bandwidth.

Optionally, 10 bits may be used to respectively indicate whether resource blocks of 10 default positions under the bandwidth are respectively allocated to users for use.

Besides the default resource blocks located at the default positions, the frequency domain resources with the bandwidth of 160MHz also include the following seven types of resource blocks located on the left side or the right side of the center frequency point of the frequency domain resources with the bandwidth of 160MHz, that is:

1 × 26 resource blocks, the smallest resource block that may be divided among the frequency domain resources of the 160MHz bandwidth, means that one resource block is composed of one sub-resource block (i.e., 26 subcarriers).

996 resource block means that one resource block is composed of 996 subcarriers.

2 × 996 resource blocks, the largest possible resource block divided among the frequency domain resources of 160MHz, indicate that one resource block is composed of 2 × 996 subcarriers.

As shown in fig. 21, for a simple description of resource block locations that may be partitioned, frequency domain resources of a 160MHz bandwidth may be partitioned into seven layers:

the first layer is a distribution diagram of 1 × 26 resource blocks and default resource blocks (i.e., 1 × 26 resource blocks located at the center of each frequency domain resource of 20MHz bandwidth and 1 × 26 resource blocks located at the center of each frequency domain resource of 80MHz bandwidth), and there are 41 × 26 resource blocks on the left and right sides of the default resource blocks at the center of each frequency domain resource of 20MHz bandwidth, where the distribution of 1 × 26 resource blocks in each frequency domain resource of 20MHz bandwidth is similar to the distribution of 1 × 26 resource blocks shown in the first layer in fig. 8, and a detailed description thereof is omitted here to avoid redundancy.

The second layer is a distribution diagram of 2 × 26 resource blocks and default resource blocks (i.e., 1 × 26 resource blocks located at the center of the frequency domain resource of each 20MHz bandwidth and 1 × 26 resource blocks located at the center of the frequency domain resource of each 80MHz bandwidth), and 2 × 26 resource blocks are respectively located on the left and right sides of the default resource block located at the center of the frequency domain resource of each 20MHz bandwidth, where the distribution of 2 × 26 resource blocks in the frequency domain resource of each 20MHz bandwidth is similar to the distribution of 2 × 26 resource blocks shown in the second layer in fig. 8, and here, detailed descriptions thereof are omitted to avoid redundancy.

The third layer is a distribution diagram of 4 × 26 resource blocks and default resource blocks (i.e., 1 × 26 resource blocks located at the center of the frequency domain resource of each 20MHz bandwidth and 1 × 26 resource blocks located at the center of the frequency domain resource of each 80MHz bandwidth), and there are 14 × 26 resource blocks on the left and right sides of the default resource block at the center of the frequency domain resource of each 20MHz bandwidth, respectively, where the distribution of 4 × 26 resource blocks in the frequency domain resource of each 20MHz bandwidth is similar to the distribution of 4 × 26 resource blocks shown in the third layer in fig. 8, and here, detailed descriptions thereof are omitted to avoid redundancy.

The fourth layer is a 242 resource block distribution diagram and a default resource block (i.e., 1 × 26 resource blocks located at the center of the frequency domain resource of each 80MHz bandwidth), and there are 1 242 resource blocks on the left and right sides of the center frequency point of the frequency domain resource of each 40MHz bandwidth, where the distribution of the 242 resource blocks in the frequency domain resource of each 40MHz bandwidth is similar to the distribution of the 242 resource blocks shown in the fourth layer in fig. 13, and here, detailed descriptions thereof are omitted to avoid redundancy.

The fifth layer is a distribution diagram of 2 × 242 resource blocks and a distribution diagram of default resource blocks (i.e., 1 × 26 resource blocks located at the center of the frequency domain resource of each 80MHz bandwidth), 1 242 resource blocks are respectively located on the left and right sides of the default resource block located at the center of the frequency domain resource of each 80MHz bandwidth, the distribution of 242 resource blocks in the frequency domain resource of each 40MHz bandwidth is similar to the distribution of 242 resource blocks shown in the fifth layer in fig. 13, and here, detailed descriptions thereof are omitted to avoid redundancy.

The sixth layer is a 996 resource block distribution diagram and a default resource block (i.e., 1 × 26 resource blocks located at the center of the frequency domain resource of each 80MHz bandwidth), there are 1 996 resource blocks on the left and right sides of the center frequency point of the frequency domain resource of each 160MHz bandwidth, and the distribution of 242 resource blocks in the frequency domain resource of each 80MHz bandwidth is similar to the distribution of 996 resource blocks shown in the sixth layer in fig. 17, and here, detailed descriptions thereof are omitted to avoid redundancy.

The seventh layer is a 2x996 resource block distribution diagram.

Here, for example, the frequency domain resource of the 160MHz bandwidth includes 2 × 996 subcarriers, and may be divided into any resource blocks in the first to sixth layers, the divided resource blocks are allocated to a plurality of users, and each user can only allocate one of the divided resource blocks.

Alternatively, for example, the frequency domain resource spectrum of the 160MHz bandwidth may be divided into resource blocks in the seventh layer, in this case, the frequency domain resource of the 160MHz bandwidth is allocated to one user, and the resource allocation may be indicated by bandwidth indication information and a single-user transmission indication bit described later.

Further, for example, the frequency domain resource spectrum of the 160MHz bandwidth may be divided into resource blocks in the seventh layer, in this case, the frequency domain resource of the 160MHz bandwidth is allocated to a plurality of users for MU-MIMO transmission, and the resource allocation may be indicated by bandwidth indication information and a multi-user transmission indication bit, which will be described later.

The resource allocation method provided by the embodiment of the invention mainly relates to the condition that the frequency domain resource of the 160MHz bandwidth is combined by any resource block from the first layer to the sixth layer and is allocated to a plurality of users.

Specifically, the combination of the frequency domain resources of the 160MHz bandwidth by any resource block in the first layer to the sixth layer refers to the combination by any number of resource blocks in the first layer to the third layer in fig. 21, and the sum of the sizes of all the resource blocks is 160MHz, as shown by the shaded portion in fig. 22 and fig. 23.

Specifically, as shown in fig. 21, the resource blocks on the left and right sides of the central frequency point of the frequency domain resource with the 160MHz bandwidth are symmetrically distributed, that is, the central frequency point can be used as the symmetric center of the frequency domain resource with the 160MHz bandwidth.

In the above, the resource block positions where various frequency domain resources to be allocated may be divided are enumerated, and the following describes in detail the process of generating resource scheduling information based on the resource block positions that may be divided.

Taking the example that the resource scheduling information includes the resource allocation bit sequence and the station information, except for the MU-MIMO transmission, the number of stations of the resource block actually divided is 1, and if the MU-MIMO transmission is adopted, the number of stations of the resource block actually divided is 8 at most and 2 at least. In the embodiment of the invention, the minimum resource block for performing MU-MIMO transmission is 4 × 26 type, so the number of sites with the size of the resource block smaller than 4 × 26 resource block is defaulted to 1, the number of sites with the size larger than or equal to 4 × 26 resource block is uncertain, the minimum is 1, and the maximum is 8.

As shown in fig. 24, taking the first identifier as 1 and the second identifier as 0 as an example, the method for generating resource scheduling information by a sending end specifically includes:

s301, the sending end obtains at least one resource block divided by the frequency domain resources.

S302, the transmitting end determines whether the first resource block is a 4 × 26 resource block, where the first resource block is a first resource block into which frequency domain resources are divided.

In the example of the first leftmost resource block, which is divided by using the frequency domain resource with the bandwidth of 20MHz and the first resource block as the frequency domain resource, the frequency domain resource with the bandwidth of 20MHz may be described by using 1 × 26 resource blocks as the symmetric center to divide blocks of the frequency domain resources on two sides. The first bit indicates whether the actually divided resource block is a 4 × 26 resource block.

S303, if the first resource block is a 4 × 26 resource block, the sending end sets a first bit of the resource allocation bit sequence as a first identifier, and sets a second bit to a fourth bit of the resource allocation bit sequence.

When the first bit is "1" to indicate that the actually divided resource block is a 4 × 26 resource block, the number of stations of the resource block is indicated by immediately following 3 bits, specifically, the sending end sets the second bit to the fourth bit of the resource allocation bit sequence to be 000, and 000 is used for indicating the first resource block to perform single-user transmission; or the sending end sets the second bit to the fourth bit of the resource allocation bit sequence to be 001, the 001 is used for indicating the first resource block to carry out multi-user multiple input multiple output (MU-MIMO) transmission, and the number of stations using the first resource block is 2; or the transmitting end sets the second bit to the fourth bit of the resource allocation bit sequence to be 010, the 010 is used for indicating the first resource block to carry out multi-user multiple input multiple output (MU-MIMO) transmission, and the number of stations using the first resource block is 3; or the sending end sets the second bit to the fourth bit of the resource allocation bit sequence to be 011, 011 is used for indicating the first resource block to carry out multi-user multiple input multiple output (MU-MIMO) transmission and the number of sites using the first resource block is 4; or the sending end sets the second bit to the fourth bit of the resource allocation bit sequence as 100, wherein 100 is used for indicating the first resource block to carry out multi-user multiple input multiple output (MU-MIMO) transmission and the number of stations using the first resource block is 5; or the sending end sets the second bit to the fourth bit of the resource allocation bit sequence to be 101, wherein 101 is used for indicating the first resource block to carry out multi-user multiple input multiple output (MU-MIMO) transmission and the number of stations using the first resource block is 6; or the sending end sets the second bit to the fourth bit of the resource allocation bit sequence as 110, and the 110 is used for indicating the first resource block to perform multi-user multiple input multiple output (MU-MIMO) transmission and the number of stations using the first resource block is 7; or the sending end sets the second bit to the fourth bit of the resource allocation bit sequence to be 111, and 111 is used for indicating the first resource block to perform MU-MIMO transmission by the MU-MIMO technique, and the number of stations using the first resource block is 8.

And S304, if the first resource block is not a 4 × 26 resource block, the sending end sets a first bit of the resource allocation bit sequence as a second identifier, and judges whether the size of the first resource block is larger than the 4 × 26 resource block.

And S305, if the size of the first resource block is smaller than 4 × 26 resource blocks, the sending end sets a second bit of the resource allocation bit sequence as a second identifier, and sets a third bit and a fourth bit of the resource allocation bit sequence.

When the first bit is "0" indicating that the actually divided resource block is not 4 × 26 resource blocks, the second bit indicates whether the size of the actually divided resource block is larger than 4 × 26 resource blocks. When the second bit "0" indicates that the size of the actually divided resource block is smaller than 4 × 26 resource blocks. Then, the actually divided resource blocks can be determined through table 1, specifically, the sending end sets the third bit and the fourth bit of the resource allocation bit sequence to 00, and 00 is used to indicate that the first four resource blocks in which the frequency domain resources are divided are 1 × 26 resource blocks; or the sending end sets the third bit and the fourth bit of the resource allocation bit sequence to be 01, and the 01 is used for indicating that the first three resource blocks into which the frequency domain resource is divided are 1 × 26 resource blocks, 1 × 26 resource blocks and 2 × 26 resource blocks in sequence; or the sending end sets the third bit and the fourth bit of the resource allocation bit sequence to be 10, and 10 is used for indicating that the first three resource blocks into which the frequency domain resource is divided are 2 × 26 resource blocks, 1 × 26 resource blocks and 1 × 26 resource blocks in sequence; or, the transmitting end sets a third bit and a fourth bit of the resource allocation bit sequence to be 11, where 11 is used to indicate that the first two resource blocks in which the frequency domain resource is divided are 2 × 26 resource blocks.

Note that the order of the resource blocks actually divided may be from right to left, and the present invention is not limited thereto. It can be understood that the bit sequences corresponding to the actually divided resource blocks can also be interchanged in the present invention. In addition, at this time, the spectrum on the right of the resource block of the symmetric center 1 × 26 is indicated according to the resource bit sequence indication method into which the left spectrum resource is actually divided.

TABLE 1

Bit sequence	Resource block being actually divided (from left to right)
		00	41 × 26 resource blocks
01	21 x 26 and 1x 52 resource blocks
		10	1 number 1x 52 and 2 number 1x 26 resource blocks
11	1 number 1x 52 and 1 number 1x 52 resource block

And S306, if the size of the first resource block is larger than 4 × 26 resource blocks, the sending end sets the second bit of the resource allocation bit sequence as the first identifier, and sets the third bit to the eighth bit of the resource allocation bit sequence.

When the second bit "1" indicates that the size of the actually divided resource block is larger than 4 × 26 resource blocks. The actually divided resource blocks can be determined by table 2, and in the first step: the sending end sets the third bit and the fourth bit of the resource allocation bit sequence to 00, and the 00 is used for indicating that the first resource block is 242 resource blocks; or the sending end sets the third bit and the fourth bit of the resource allocation bit sequence to be 01, and 01 is used for indicating that the first resource block is a 2 × 242 resource block; or the third bit and the fourth bit of the resource allocation bit sequence are set to be 10 by the sending end, and the 10 is used for indicating that the first resource block is 996; or the third bit and the fourth bit of the resource allocation bit sequence are set to be 11 by the transmitting end, and 11 is used for indicating that the first resource block is a 2 × 996 resource block. It can be understood that the bit sequences corresponding to the actually divided resource blocks can also be interchanged in the present invention.

TABLE 2

Bit sequence	Resource block actually divided
		00	242 resource blocks
01	2x 242 resource blocks
		10	996 resource blocks
11	2 × 996 resource blocks

Further, when the second bit "1" indicates that the size of the actually divided resource block is larger than 4 × 26 resource blocks. The actually divided resource blocks can also be represented by logical bits, and no table is required to be stored. Wherein the third bit indicates whether the actually divided resource block is a 996 resource block, and when the third bit "0" indicates that the actually divided resource block is not a 996 resource block, the fourth bit indicates whether the actually divided resource block is a 2 × 242 resource block. Thus, "10" indicates that the actually divided resource block is 996 resource block, "01" indicates that the actually divided resource block is 2 × 242 resource block, "00" indicates that the actually divided resource block is 242 resource block, and another special bit sequence "11" indicates that the actually divided resource block is 2 × 996 resource block.

In addition, when the second bit "1" indicates that the size of the actually divided resource block is larger than 4 × 26 resource blocks, the spectrum resource on the right of the resource block at the center of symmetry 1 × 26 is also divided, so that the 4 bits on the right of the resource block at the center of symmetry 1 × 26 can be used to indicate the number of stations transmitting on the actually divided resource block. Specifically, the method comprises the following steps: and the transmitting end sets the fifth bit of the resource allocation bit sequence as a reserved bit. Setting the sixth bit to the eighth bit of the resource allocation bit sequence as 000 by the sending end, wherein the 000 is used for indicating the first resource block to carry out single-user transmission; or the sending end sets the sixth bit to the eighth bit of the resource allocation bit sequence to be 001, the 001 is used for indicating the first resource block to carry out multi-user multiple input multiple output (MU-MIMO) transmission, and the number of stations using the first resource block is 2; or the transmitting end sets 010 as the sixth bit to the eighth bit of the resource allocation bit sequence, the 010 being used for indicating the first resource block to perform MU-MIMO transmission in the multi-user multiple input multiple output technique, and the number of stations using the first resource block being 3; or the sending end sets the sixth bit to the eighth bit of the resource allocation bit sequence to be 011, 011 is used for indicating the first resource block to carry out multi-user multiple input multiple output (MU-MIMO) transmission and the number of sites using the first resource block is 4; or the sending end sets the sixth bit to the eighth bit of the resource allocation bit sequence to be 100, wherein 100 is used for indicating the first resource block to carry out multi-user multiple input multiple output (MU-MIMO) transmission and the number of stations using the first resource block is 5; or the sending end sets the sixth bit to the eighth bit of the resource allocation bit sequence to be 101, wherein 101 is used for indicating the first resource block to carry out multi-user multiple input multiple output (MU-MIMO) transmission and the number of stations using the first resource block is 6; or the sending end sets the sixth bit to the eighth bit of the resource allocation bit sequence as 110, and the 110 is used for indicating the first resource block to perform MU-MIMO transmission by the multi-user multiple input multiple output technique, and the number of stations using the first resource block is 7; or the sending end sets the sixth bit to the eighth bit of the resource allocation bit sequence to be 111, and 111 is used for indicating the first resource block to perform MU-MIMO transmission by the MU-MIMO technique, and the number of stations using the first resource block is 8.

Based on the embodiment of the present invention, the 8 bits of the resource allocation bit sequence and the indicated actually divided resource blocks can be simply represented in a table. As shown in table 3 below, a total of 256 resource allocation bit sequences are indicated by 8 bits.

In table 3, 26 indicates 1 × 26 resource blocks; 52 indicates 2 × 26 resource blocks; 106 indicate 4 by 26 resource blocks; 242(n) indicates 242 resource blocks, and the number of stations transmitting on the resource is n, and when n is greater than 1, the resource blocks perform MU-MIMO transmission; 484(n) indicates 2 × 242 resource blocks, and the number of stations transmitting on this resource is n; 996(n) indicates a 996 resource block, and the number of stations transmitted on the resource is n; 2x996(n) indicates a 2x996 resource block, and the number of stations transmitting on this resource is n.

In table 3, if all bits take the first flag as 1 and the second flag as 0 as an example, the resource allocation sequence indicating the actually divided resource blocks is the resource allocation bit sequence 1 in the following table. If the first flag of the 5 th bit is 0, the second flag is 1, and all other bits take the first flag as 1 and the second flag as 0 as an example, the resource allocation sequence of the actually divided resource block is indicated as the shaded resource allocation bit sequence 2 in the following table. It can be understood that the first identifier and the second identifier of each bit have different values, which indicates that the resource allocation sequence of the actually divided resource block is a different sequence, and the corresponding tables are also different. Therefore, the present invention is not limited to the resource allocation bit sequence 1 and the resource allocation bit sequence 2 in the table. In addition, the values of the first flag and the second flag of the fifth reserved bit (referring to the 5 th bit when the 2 nd bit is the first value) will also cause the resource allocation bit sequences in the table to be different. In table 3 below, resource allocation bit sequence 1 and resource allocation bit sequence 2 are both used: when the fifth reserved bit is 1, the sixth bit to the eighth bit are reserved bits; and when the fifth reserved bit is 0, indicating the number of stations transmitted on the first resource block by the sixth bit to the eighth bit.

For example, as shown in fig. 25, the resource allocation bit sequence generated after the spectrum resource block with the bandwidth of 20MHz is divided is "10101000", the meaning of the resource allocation bit sequence is explained by taking the previous 4 bits "1010" as an example, the first bit "1" indicates that the spectrum resource on the left of the symmetric center 1 × 26 resource block is actually divided into 4 × 26 resource blocks, and the next three bits "010" indicate that the number of stations transmitted on the 4 × 26 resource block is 3.

The resource allocation bit sequence generated after the spectrum resource block shown in fig. 25 is divided is 129 in the resource allocation bit sequence 1 in table 3, which indicates that the resource allocation bit sequence generated after the spectrum resource block is divided is "10101000", the spectrum resource block is actually divided into 4 × 26 resource blocks to the left of the center of symmetry 1 × 26 resource block, the number of stations transmitting on the resource block is 3, for MU-MIMO transmission, the spectrum resource to the left of the center of symmetry 1 × 26 resource block is actually divided into 4 × 26 resource blocks, and the number of stations transmitting on the resource block is 1.

The first digit "0" indicates that the spectral resources to the left of the center of symmetry 1x 26 resource block are actually divided into non-4 x 26 resource blocks, and the second digit "1" indicates that the spectral resources to the left of the center of symmetry 1x 26 resource block are actually divided into more than 4 x 26 resource blocks. Bits 3-4 "01" indicate that the spectrum resources to the left of the center of symmetry 1x 26 resource blocks are actually divided into 2x 242 resource blocks. The last three bits "110" indicate that the number of stations actually divided into 2x 242 resource blocks for transmission is 7.

When Y is 0, the following "110" indicates that the number of stations actually divided into 2 × 242 resource blocks for transmission is 7, and when Y is 1, the following 3 bits are reserved bits. The value of Y can indicate the opposite.

For example, as shown in fig. 27, the resource blocks of the spectrum with the bandwidth of 80MHz are actually divided into resource blocks, the resource allocation bit sequence generated by the first spectrum resource with the bandwidth of 20MHz is "10001000", the resource allocation bit sequence generated by the second spectrum resource with the bandwidth of 20MHz is "0100Y 000", and the resource allocation bit sequences generated by the third and fourth spectrum resources with the bandwidth of 20MHz are both "0101Y 101".

When Y is 1, the following "110" indicates that the number of stations actually divided into 2 × 242 resource blocks for transmission is 6, and when Y is 0, the following 3 bits are reserved bits. The value of Y can indicate the opposite.

The resource allocation bit sequence generated after the first 20MHz spectrum resource block is divided shown in fig. 27 is 97 resource allocation bit sequences 1 in the table, which indicates that the resource allocation bit sequence generated after the spectrum resource block is divided is "10001000", the spectrum resource block is actually divided into 4 × 26 resource blocks, 1 × 26 resource blocks and 4 × 26 resource blocks (from left to right), wherein the number of stations transmitting on 24 × 26 resource blocks is all 1.

There are a plurality of resource allocation bit sequences as reserved sequences in table 3, and 80 reserved sequences in table 3. In addition, if the number of stations transmitted on each 20M is at most 9, the sequence numbers in table 3 are 104, 119-120, 134-136, 149-152, 164-168, 179-184, 194-200, and 209-216, which are reserved sequences, and 36 in total, because the total number of stations transmitted on all resource blocks corresponding to the sequences exceeds 9. Further, the resource block 2x996 (also referred to as 2x996 resource block) corresponding to the maximum bandwidth of 160MHz can be indicated in the HE-SIGA field, and the sequence numbers 81 to 88 in table 3 are reserved sequences, and total number is 8. At this time, there are 132 resource allocation bit sequences indicating that the spectrum resource block is actually divided, among which there are 108 bit sequences indicating that the resource block actually divided contains the middle 1 × 26 resource blocks, and there are 32 types in table 3, namely 242(n), 484(n), and 996(n), indicating that the resource block actually divided does not contain the middle 1 × 26 resource blocks.

The invention adopts the reserved bits to indicate whether 1 × 26 resource blocks are used (whether to be allocated to the station), and as the bit sequence indicating that the resource blocks into which the spectrum resource blocks are actually divided contain the middle 1 × 26 resource blocks is 108, the corresponding reserved bits need to indicate that the middle resource blocks 1 × 26 in the case that the spectrum is actually divided in 108 are not used, as shown in table 4, a single 'x' in the table indicates that the middle resource blocks 1 × 26 are not used.

In table 4, resource allocation bit sequence 1 and resource allocation bit sequence 2 are the same as in table 3, but the reservation sequence is used to indicate that the middle resource block 1 × 26 resource block in the case where the spectrum is actually divided is not used, wherein the case where the middle resource block 1 × 26 resource block in the case where the spectrum is actually divided is a shaded portion of "actually divided resource block (from left to right)" in table 4. It should be noted that the resource allocation bit sequence 1 and the resource allocation bit sequence 2 in table 3 or table 4 are optional, that is, one of the resource allocation bit sequences should be stored in the protocol specification or the product, or other possible variants. For an actually divided resource block, only one resource allocation bit sequence (or called sequence) corresponds to the actually divided resource block during implementation, so that a receiving end can know the condition of the actually divided resource block according to the resource allocation bit sequence.

TABLE 4

In addition, the reserved bits in table 3 or table 4 may also be used to indicate the special case of HE-SIGB site information load balancing on the HE-SIG-B20M, for example, a resource allocation bit sequence reserved with a sequence number 81 (for indicating another resource allocation special sequence of 484 resource blocks) indicates that the number of sites corresponding to the resource allocation bit sequence carried in the 20M HE-SIGB in which the reserved resource allocation bit sequence is located is 0, and a reserved resource allocation bit sequence with a sequence number 82 (for indicating another resource allocation special sequence of 996 resource blocks) indicates that the number of sites corresponding to the resource allocation bit sequence carried in the 20M HE-SIGB in which the reserved resource allocation bit sequence is located is 0; in addition, the reserved bits in table 3 or table 4 may also be used in other cases, which is not limited in the present invention.

Based on the embodiments of the present invention, the 8 bits of the resource allocation bit sequence and the indicated actually divided resource blocks may also employ the working principle schematic (flow chart) as shown in fig. 41a, 41b and 41c to generate the resource allocation bit sequence or parse the resource allocation bit sequence. In fig. 41a, 41b and 41c, 26 indicates 1 × 26 resource blocks; 52 indicates 2 × 26 resource blocks; 106 indicate 4 by 26 resource blocks; 242 indicates 242 resource blocks; 484 indicates 2 × 242 resource blocks; 996 indicates 996 resource blocks, 2x996 resource blocks.

Fig. 41a shows a generation or parsing process of the first 4 bits of an 8-bit resource allocation bit sequence, where "x" represents a bit to be generated or parsed in the first 4 bits, and "-" represents the last 4 bits, and there are 2 outlets in the flowchart: 1. in special cases, the resource block is larger than 106 resource blocks; 2. and generating or reading a 5 th-8 th bit resource indication (indicating a right resource block).

In fig. 41b, the second exit of fig. 41a is taken as an entry, which illustrates the generation or parsing process of the last 4 bits, where "x" represents the bit to be generated or parsed in the last 4 bits, and "-" represents the first 4 bits.

In fig. 41c, the first exit of fig. 41a is used as an entry to illustrate the generation or parsing process of the last 4 bits, where "x" represents the bit to be generated or parsed in the last 4 bits, and "-" represents the first 4 bits. If the resource block 2x996 corresponding to the maximum bandwidth of 160MHz (also referred to as 2x996 resource block) is not indicated in the HE-SIGA field, in fig. 41c, '0111, - - - - - - - - -' → 2x996 resource block or the reserved sequence "is 2x996 resource block"; if the resource block 2x996 (also referred to as 2 × 996) corresponding to the maximum bandwidth 160MHz is indicated in the HE-SIGA field, in fig. 41c, ' 0111 ' - - - - - - - - - - - - ' → 2x996 resource block or the reserved sequence "is a reserved sequence, where the reserved sequence may be used to indicate that the number of the station information corresponding to the resource allocation bit sequence carried in the 20M HE-SIGB in which the reserved resource allocation bit sequence (e.g., a special resource allocation sequence indicating 484 resource blocks or a special resource allocation sequence indicating 996 resource blocks) is 0, for example, ' 0111,0yy '", and the reserved sequence may also be used as another indication.

It is to be understood that the flow charts of fig. 41a, 41b and 41c described above are one example thereof. If the first identifier and the second identifier of each bit in the resource allocation sequence have different values, the corresponding value of the flowchart is determined to be changed accordingly, which is similar to the possible deformation of the resource allocation sequence in table 3 or table 4. For example, the 5 th bit has a first identifier value of 0 and a second identifier value of 1, the other bits have a first identifier value of 1 and a second identifier value of 0, and the resource allocation bit sequence generated after the spectrum resource block is divided is the resource allocation bit sequence 2 in table 3; and all the bits take the first identifier value 1 and the second identifier value 0, and the resource allocation bit sequence generated after the frequency spectrum resource block is divided is the resource allocation bit sequence 1 in the table 3.

Example 4

Next, another process of generating resource scheduling information based on resource block positions that may be divided is explained in detail.

Except for MU-MIMO transmission, the number of sites of the actually divided resource blocks is 1, and if the MU-MIMO transmission is adopted, the number of sites of the actually divided resource blocks is 8 at most and 2 at least. In the embodiment of the invention, the minimum resource block for performing MU-MIMO transmission is 242 resource blocks, so the number of stations with the resource block size smaller than 242 resource blocks is defaulted to 1, the number of resource blocks larger than or equal to 4 × 26 is uncertain, and the minimum is 1 and the maximum is 8.

As shown in fig. 28, taking the first identifier as 1 and the second identifier as 0 as an example, the method for generating resource scheduling information by a sending end specifically includes:

s401, the sending end obtains at least one resource block divided by the frequency domain resources.

S402, the sending end generates a resource allocation bit sequence according to at least one resource block divided by the frequency domain resource.

If the first bit, the second bit and the third bit of the resource allocation bit sequence are the first identifiers, the first resource block into which the frequency domain resources are divided is a 4 × 26 resource block; or, if the first bit and the third bit of the resource allocation bit sequence are the first identifier and the second bit is the second identifier, the first two resource blocks into which the frequency domain resource is divided are 2 × 26 resource blocks; or if the first bit of the resource allocation bit sequence is the first identifier, and the second bit and the third bit are the second identifiers, the first three resource blocks into which the frequency domain resource is divided are sequentially 2 × 26 resource blocks, 1 × 26 resource blocks and 1 × 26 resource blocks; or, if the first bit and the second bit of the resource allocation bit sequence are the second identifier and the third bit is the first identifier, the first three resource blocks into which the frequency domain resource is divided are 1 × 26 resource blocks, 1 × 26 resource blocks and the first three resource blocks into which the frequency domain resource is divided in sequence

2 × 26 resource blocks; or if the first bit, the second bit and the third bit of the resource allocation bit sequence are the second identifier, the first four resource blocks into which the frequency domain resources are divided are 1 × 26 resource blocks; or, if the resource allocation bit sequence is 011, the first resource block into which the frequency domain resource is divided is 242 resource blocks; or, if the resource allocation bit sequence is 110, the first resource block into which the frequency domain resource is divided is 2 × 242 resource blocks; alternatively, if the resource allocation bit sequence is 010, the first resource block into which the frequency domain resource is divided is 996 resource blocks.

Further, if the resource allocation bit sequence is 011, 110 or 010, the sending end sets the fourth bit to the sixth bit of the resource allocation bit sequence to 000, and the 000 is used for indicating the first resource block to perform single-user transmission; or the sending end sets the fourth bit to the sixth bit of the resource allocation bit sequence to be 001, the 001 is used for indicating the first resource block to carry out multi-user multiple input multiple output (MU-MIMO) transmission, and the number of stations using the first resource block is 2; or the sending end sets the fourth bit to the sixth bit of the resource allocation bit sequence to be 010, the 010 is used for indicating the first resource block to perform multi-user multiple input multiple output (MU-MIMO) transmission, and the number of stations using the first resource block is 3; or the sending end sets the fourth bit to the sixth bit of the resource allocation bit sequence to be 011, 011 is used for indicating the first resource block to carry out multi-user multiple input multiple output (MU-MIMO) transmission and the number of sites using the first resource block is 4; or the sending end sets the fourth bit to the sixth bit of the resource allocation bit sequence to be 100, wherein 100 is used for indicating the first resource block to carry out multi-user multiple input multiple output (MU-MIMO) transmission and the number of stations using the first resource block is 5; or the sending end sets the fourth bit to the sixth bit of the resource allocation bit sequence to be 101, wherein 101 is used for indicating the first resource block to carry out multi-user multiple input multiple output (MU-MIMO) transmission and the number of stations using the first resource block is 6; or the sending end sets the fourth bit to the sixth bit of the resource allocation bit sequence as 110, and the 110 is used for indicating the first resource block to perform MU-MIMO transmission by the multi-user multiple input multiple output technique, and the number of stations using the first resource block is 7; or the sending end sets a fourth bit to a sixth bit of the resource allocation bit sequence to be 111, where 111 is used to instruct the first resource block to perform MU-MIMO transmission in the MU-MIMO technology, and the number of stations using the first resource block is 8.

As shown in fig. 29, the frequency resources of 20MHz bandwidth may be divided into 9 1 × 26 resource blocks.

The invention proposes to use the baffle method to point out the combination of frequency resource division, put 1 bit in the position of 6 corresponding arrowheads in figure 29 separately, when this bit is "1", show that 2 adjacent resource blocks are linked together, can make up into the resource block bigger than 1 × 26 resource blocks; when the bit is "0", it indicates that the adjacent 2 resource blocks are separated. Referring to the resource block position diagram of fig. 8, which may be divided, the middle 1 × 26 resource blocks may not be combined with other resource blocks to form other resources, and therefore, no arrow is placed beside the resource block 2.

As shown in fig. 30, the resource allocation information is indicated as "111111", which indicates that the left 4 resource blocks 1 × 26 resource blocks of the middle 1 × 26 resource block are combined together to form 4 × 26 resource blocks, and the right 4 resource blocks 1 × 26 resource blocks of the middle 1 × 26 resource block are combined together to form 4 × 26 resource blocks.

As shown in fig. 31, the resource allocation information is indicated as "101111", which indicates that the left 2 resource blocks 1 × 26 resource blocks in the middle 1 × 26 resource block are connected together to form 2 × 26 resource blocks, the next 2 resource blocks 1 × 26 are connected together to form 2 × 26 resource blocks, and the right 4 resource blocks 1 × 26 resource blocks in the middle 1 × 26 resource block are connected together to form 4 × 26 resource blocks.

As shown in fig. 32, the resource allocation information is indicated as "101000", which indicates that the left 2 resource blocks of 1 × 26 in the middle are connected together to form 2 × 26 resource blocks, the next 2 resource blocks of 1 × 26 are connected together to form 2 × 26 resource blocks, and the right 4 resource blocks of 1 × 26 in the middle are not connected together and are divided into 1 × 26 resource blocks.

Referring to fig. 8, it can be known that the indication bits on the left or right of the middle resource block may not be "011", "110", or "010". For example, the left side of the middle resource block indicates bit "110", which indicates that the first 3 left 1 × 26 resource blocks on the left side of the middle 1 × 26 resource block are connected together to form a large resource block, but there is no such resource block. We can use these special indicator bits to indicate other meanings. For example, the frequency domain resource of 20MHz bandwidth is divided into 242 resource blocks by "011 XXX", wherein a 3-bit binary number "X" is used to indicate the number of stations transmitting on the 242 resource blocks, 000 "indicates that the number of stations is 1, 001" indicates that the number of stations is 2, and so on.

For frequency domain resources with bandwidth greater than 20MHz, such as frequency domain resources with bandwidth of 40MHz, the frequency domain resources that can be divided into 2 frequency domain resources with bandwidth of 20MHz are respectively indicated by actually divided resource blocks, but there is one more resource block type that may be divided, such as 2 × 242 resource blocks. This is indicated here using special indication bits, such as representing the 20MHz bandwidth frequency domain resource by "110 XXX" combined with the adjacent 20MHz bandwidth frequency domain resource into 2x 242 resource blocks. The frequency domain resource of the 20MHz bandwidth is denoted by "010 XXX" and is combined with two adjacent frequency domain resources of the 20MHz bandwidth to form one 996 resource block.

Illustratively, as shown in fig. 33, a schematic diagram of frequency domain resources of 40MHz bandwidth being actually divided is shown, a first frequency domain resource indication bit sequence of 20MHz bandwidth is "011001", and a second frequency domain resource indication bit sequence of 20MHz bandwidth is also "011001".

For example, as shown in fig. 34, a schematic diagram that frequency domain resources with a bandwidth of 80MHz are actually divided is shown, where a first frequency domain resource indication bit sequence with a bandwidth of 20MHz is "111111", a second frequency domain resource indication bit sequence with a bandwidth of 20MHz is "110011", a third frequency domain resource indication bit sequence with a bandwidth of 20MHz is "011000", and a fourth frequency domain resource indication bit sequence with a bandwidth of 20MHz is also "011000".

It should be noted that, the first identifier provided in the embodiment of the present invention is 1, the second identifier is 0, or the first identifier is 0, and the second identifier is 1, or an identifier agreed by any receiving end and any transmitting end, which is not limited in the present invention.

Example 5

If the resource scheduling information only includes the resource allocation bit sequence, the site information is not included. That is, it does not include which resource blocks are used for MU-MIMO transmission indication and which resources are used for single-user transmission indication. The minimum resource block of the MU-MIMO transmission is considered here to be 4 × 26 resource blocks. The embodiment of the invention provides that the number of stations transmitted on a bit indication resource block is additionally increased and is placed in the station information.

The encoding mode of HE-SIG-B is that information of K sites is encoded individually, and there are 2 modes, one is that a common parameter part is encoded independently, and information of each following K sites is encoded independently, as shown in fig. 35. Another way is to encode the public parameters with the information of the first K sites and the information of each of the following K sites independently, as shown in fig. 36. The bit number contained in each station information group is fixed and equal, and the common information parameter group may have the same size as the station information group or may be different, but the receiving end is known. The value of K is any positive integer and can be 3 or 4.

The embodiment of the present invention proposes that adding 3 bits in a specific coding block except the first independent coding block indicates the number of stations actually divided into 4 × 26 resource blocks or larger, where the indicated bit position is not limited and is preferably located in front of the coding block. E.g., 000 indicates 1 station participating in the transmission, 001 indicates 2 stations participating in the transmission, and so on. More than 1 station participates in transmission, which means MU-MIMO transmission is carried out on the resource block, namely 3 bits of '001-111' mean MU-MIMO transmission, and '000' means single-station transmission. The bits indicating the number of sites transmitted on 4 x 26 resource blocks or larger are placed within the assigned code block so that the receiver knows how many bits each code block contains and can decode correctly. When 20M contains 2 resource blocks of 4 × 26, 6 bits are added in the designated code block in 20M to indicate the number of stations on the resource block, and when 20M contains 1 resource block of 4 × 26, or 242 resource blocks, or a larger resource block is combined with the adjacent frequency domain resource of 20MHz bandwidth, 3 bits are added in the designated code block in the frequency domain resource of 20MHz bandwidth to indicate the number of stations on the resource block.

Illustratively, the frequency domain resources of 20MHz bandwidth are divided into 24 × 26 resource blocks, each resource block needs to be increased by 3 bits to indicate the number of stations transmitting on the resource block, and one embodiment is that the transmitting end places these 6 bits in front of the second coding block.

The receiving end decodes the first block (the number of bits included in the first block is known), and knows that the resource allocation information of the first block contains 24 × 26 resource blocks. The receiver knows that the second block of code has an additional 6 bits added to it, allowing for efficient decoding.

Illustratively, the frequency domain resource of 20MHz bandwidth is divided into 1 resource block of 4 × 26, and 3 bits need to be added to indicate the number of stations transmitting on the resource block, and one embodiment is to place the 3 bits in front of the second coding block by the transmitting end.

The receiving end decodes the first block (the number of bits included in the first block is known), and knows that the resource allocation information of the first block contains 14 × 26 resource blocks. The receiver knows that the second block of code has been added by an additional 3 bits to enable efficient decoding.

Illustratively, the frequency domain resources of the 80MHz bandwidth are divided into: the first 20MHz bandwidth frequency resource contains 24 x 26 resource blocks, and the transmitting end places these 6 bits in front of the second coded block in the first 20MHz bandwidth frequency resource. The divided frequency resources of the second 20MHz bandwidth contain 1 242 resource blocks, and the transmitting end places the 3 bits in front of the second coding block in the frequency resources of the second 20MHz bandwidth. The divided third 20MHz bandwidth frequency domain resource is divided into 2x 484 resource blocks together with the adjacent 20MHz bandwidth frequency domain resource, and the transmitting end places the 3 bits in front of the second coding block in the third 20MHz bandwidth frequency domain resource. The divided fourth 20MHz bandwidth frequency domain resource is divided into 2x 484 resource blocks together with the adjacent 20MHz bandwidth frequency domain resource, and the transmitting end places the 3 bits in front of the second coding block in the fourth 20MHz bandwidth frequency domain resource.

The receiving end firstly decodes the first block coding block (the bit number of the first block coding block is known) in the frequency domain resource of each 20MHz bandwidth, and the number of the resource blocks containing 4 × 26 resource blocks and larger resource blocks is known through the resource allocation information of the first block coding. The receiver knows how many bits are added to the second block code block to enable efficient decoding.

It should be noted that the above embodiment is not limited to adding the bit information indicating the number of stations on the 4 × 26 resource blocks and larger resource blocks in the second coding block. But may be known to the receiving end within other code blocks.
