The priority of the Chinese Patent Application No. 20151064261, the entire disclosure of which is incorporated herein by reference.

Technical field

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

Background technique

With the continuous development of communication technologies, in a WLAN system (for example, 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 blocks is indicated (for example, indication MU-MIMO (Multi-User Multiple-Input Multiple-Output) transmission can be performed on which resource block. Among them, 802.11ax is an 802.11 wireless LAN communication standard, which transmits through the 5G frequency band, which is a subsequent upgrade version of 802.11ac. MU-MIMO is a technology that allows a router to communicate with multiple devices at the same time.

The existing resource allocation method adopts a resource block-based bitmap indication manner to inform the receiving end of the resource allocation mode on the current transmission bandwidth. Specifically, the bitmap indication mode uses a continuous sequence of “1” or “0” to indicate resource blocks allocated to the same station, and jumps from “1” to “0” or “0” to “1”. "To indicate that a resource block is assigned to another site. Therefore, the number of bits used to indicate the resource allocation pattern on the current transmission bandwidth is equal to the number of resource blocks on the current transmission bandwidth. For example, as shown in FIG. 1, there are nine 1*26 resource blocks on a bandwidth of 20 MHz, and then the number of bits used to indicate the resource allocation pattern on the current transmission bandwidth is equal to 9 bits. If the receiving end receives a bitmap indication sequence of "110010000", then it can be known that the first and second resource blocks are allocated to the station 1, the third and the fourth resource block are allocated to the station 2. The fifth resource block is allocated to station 3, and the remaining four resource blocks are allocated to station 4. It should be noted that the bitmap indication sequence received by the receiving end indicates that the resource block actually divided is corresponding to the following station information. For example, the bitmap indicated by the resource block in FIG. 1 is "110010000", Site 1 information, Site 2 information, Site 3 information, and Site 4 information. Each site information contains a site identity, which is used to identify the site and is the identity of the site.

However, when the resource allocation method is used to divide the bandwidth resource, the number of bits used to indicate the resource allocation mode on the current transmission bandwidth is equal to the number of resource blocks on the current transmission bandwidth, instead of the current transmission bandwidth being actually The number of resource blocks divided. For a bandwidth of 80 megahertz or a bandwidth of 160 megahertz, the number of resource blocks that may be divided is large, so the number of bits used to indicate the resource allocation pattern on the current transmission bandwidth is also increased.

Optionally, 1 bit may be used to indicate whether the resource block of the default location is allocated for use by the user.

Specifically, as shown in FIG. 7, the frequency domain resource of the 20 MHz bandwidth may include a default resource block located at the center (ie, a resource block located at a default location), and the default resource block may be a resource block of a type 1*26, that is, A resource block that spans DC (subcarrier-1, 0, 1) and includes 26 subcarriers. The default resource block exists in the communication system by default, and is independently allocated, that is, each resource of 20 MHz bandwidth to be allocated is divided into a default resource block of type 1*26 at its central location, and the default resource block is independently assigned to one. The receiving end, and the receiving end to which the default resource block is allocated and the default resource The receiving ends to which the resource blocks adjacent to the left or right side of the source block are allocated may be the same or different, and the present invention is not particularly limited.

The 4*26 resource block includes 106 subcarriers, that is, 102 data subcarriers and 4 pilot subcarriers. In the following description of the present invention, the description of the same or similar cases is omitted in order to avoid redundancy.

As shown in FIG. 8, in order to briefly describe the location of a resource block that may be divided, the frequency domain resource of 20 MHz bandwidth may be divided into four layers:

A 1*26 resource block, that is, a resource block located at resource block position #7 to position #10 and position #11 to position #14 shown in FIG.

The second layer is a distribution map of the 2*26 resource block and the default resource block (ie, 1*26 resource block located at the center of the frequency domain resource of the 20 MHz bandwidth), and there are 2 on the left and right sides of the default resource block located at the center, respectively. A 2*26 resource block, that is, a resource block located at position #1 to position #4 shown in FIG.

A 4*26 resource block, that is, a resource block located at position #5 and position #6 shown in FIG.

The fourth layer is 242 resource blocks. As shown in FIG. 8, the 242 resource block includes the subcarrier in which the aforementioned symmetric center is located.

Also, each user can only allocate one of the divided resource blocks.

Or, for example, the frequency domain resource spectrum of the 20 MHz bandwidth may be divided into resource blocks in the fourth layer. In this case, the frequency domain resource of the 20 MHz bandwidth is allocated to one user, and the bandwidth indication information and the bandwidth information described later may be used.

The frequency domain resource of 40 MHz bandwidth can be regarded as composed of two frequency domain resources of 20 MHz bandwidth. Correspondingly, the frequency domain resources of each 20 MHz bandwidth may include a default resource block located in the frequency domain resource center of the 20 MHz bandwidth (ie, the default resource block) The resource block of the location), and the configuration and allocation manner of the default resource block (two in total) in the frequency domain resource of the 40 MHz bandwidth is similar to the configuration and allocation mode of the default resource block in the frequency domain resource of the 20 MHz bandwidth. Here, in order to avoid redundancy, a detailed description thereof will be omitted.

Optionally, two bits may be used to indicate whether the resource blocks of the two default locations of the bandwidth are allocated for use by the user. In addition to the above default resource blocks located in the default location, the frequency domain resources of the 40 MHz bandwidth further include the following five types of resource blocks to the left or right of the center frequency of the frequency domain resources of the 40 MHz bandwidth, namely:

On the right side, there are 4 1*26 resource blocks respectively, wherein the distribution of 8 1*26 resource blocks in the frequency domain resources per 20 MHz bandwidth is the same as the 1*26 resource blocks shown in the first layer in FIG. The distribution is similar, and the detailed description thereof is omitted here to avoid redundancy.

The second layer is a distribution map of 2*26 resource blocks and default resource blocks (ie, 1*26 resource blocks each located in the center of the frequency domain resource of 20MHz bandwidth), on the left and right sides of the default resource block located in each center. There are two 2*26 resource blocks (for example, position #E and position #F in FIG. 13), wherein the distribution of four 2*26 resource blocks per 20 MHz bandwidth is the same as the second layer in FIG.

Wherein, the frequency domain resource of the 40 MHz bandwidth includes 484 subcarriers, and may be divided into any resource blocks in the first layer to the fourth layer in FIG. 13, and the divided resource blocks are allocated to multiple users. Also, each user can only allocate one of the divided resource blocks.

Or, for example, the frequency domain resource spectrum of the 40 MHz bandwidth may be divided into resource blocks in the fifth layer. In this case, the frequency domain resource of the 40 MHz bandwidth is allocated to one user, and the bandwidth indication information and the following may be used. The single user transmission indication bit indicates the case of resource allocation.

Furthermore, the exemplary frequency domain resource spectrum of the 40 MHz bandwidth may be divided into resource blocks in the fifth layer. In this case, the frequency domain resource of the 40 MHz bandwidth is allocated to multiple users for MU-MIMO transmission, and The case of resource allocation is indicated by the bandwidth indication information and the multi-user transmission indication bit described later.

The resource allocation method provided by the embodiment of the present invention mainly relates to a case where a frequency domain resource of a 40 MHz bandwidth is composed of any one of the first to fourth layers and is allocated to multiple users.

Specifically, the frequency domain resource of the 40 MHz bandwidth is any combination of the resource blocks of the first layer to the fourth layer in the first layer to the fourth layer, and the size of all the resource blocks is combined. The sum is 40 MHz, as shown in the shaded portion of Figure 14 or Figure 15.

For example, FIG. 16 shows a resource allocation method of frequency domain resources of 40 MHz bandwidth. 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 (ie, resource block #E and resource block #F in FIG. 13), a 1*26 resource block (ie, resource block #0), which is a default resource block), and a 4*26 resource block (ie, FIG. 13) Resource block #D) and a 242 resource block (ie, resource block #B in Figure 13).

(Subcarrier-1, 0, 1) and includes resource blocks of 26 subcarriers. The default resource block exists by default in the communication system, and is independently allocated, that is, each resource of the 80 MHz bandwidth to be allocated is divided into a default resource block of 1*26 size at its central location, and the default resource block is independently assigned to one. The receiving end, and the receiving end to which the default resource block is allocated and the resource block to which the resource block adjacent to the left or the right side of the default resource block is allocated may be the same or different, and the present invention is not particularly limited. For a frequency domain resource of 80 MHz bandwidth, when the receiving end allocated by the default resource block 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, the frequency domain resource of the 80 MHz bandwidth is indicated. Only assigned to one user. Otherwise, the receiving end to which the default resource block is assigned is different from the receiving end to which the resource block adjacent to the left or right side of the default resource block is allocated.

Moreover, the frequency domain resource of the 80 MHz bandwidth can be regarded as consisting of two frequency domain resources of 40 MHz bandwidth and one default resource block located at the symmetric center, and each frequency domain resource of 40 MHz bandwidth can be regarded as a frequency domain of two 20 MHz bandwidths. The resource composition, correspondingly, the frequency domain resource of each 20 MHz bandwidth may include a default resource block (ie, a resource block located at a default location) located in the frequency domain resource center of the 20 MHz bandwidth.

In addition to the default resource blocks in the default location, the frequency domain resources of the 80 MHz bandwidth include the following six types of resource blocks to the left or right of the default resource block of the frequency domain resource center of the 80 MHz bandwidth, namely:

There are one 242 resource blocks on both sides, that is, resource blocks located at position #c and position #d shown in FIG. 17, wherein the distribution of resource blocks of 242 in the frequency domain resources per 40 MHz bandwidth is the fourth in FIG.

In this case, the frequency domain resource of the 80 MHz bandwidth is allocated to one user, and the bandwidth indication information and the following may be used. The single user transmission indication bit indicates the case of resource allocation.

The sum is 80 MHz, as shown in the shaded portion in Fig. 18 or Fig. 19.

Correspondingly, each 80MHz bandwidth frequency domain resource may include a default resource block located in the frequency domain resource center of the 80MHz bandwidth (ie, the default resource block). The resource block of the location), and the frequency domain resource of each 20 MHz bandwidth in the 160 MHz bandwidth frequency domain resource may include a default resource block (ie, a resource block located at a default location) located in the frequency domain resource center of the 20 MHz bandwidth.

The third layer is a 4*26 resource block and a default resource block (ie, 1*26 resource block located at the center of the frequency domain resource per 20 MHz bandwidth and 1*26 resource block located at the center of the frequency domain resource per 80 MHz bandwidth) The distribution map has a 4*26 resource block on each of the left and right sides of the default resource block of the frequency domain resource center location of each 20 MHz bandwidth, wherein the distribution of 4*26 resource blocks in the frequency domain resource per 20 MHz bandwidth is The distribution of 4*26 resource blocks shown in the third layer in Figure 8 is similar, here, to avoid The detailed description is omitted.

The fourth layer is a distribution map of the 242 resource block distribution map and the default resource block (ie, 1*26 resource blocks located at the center of the frequency domain resource per 80 MHz bandwidth), at the frequency center of the frequency domain resource located at each 40 MHz bandwidth. There are one 242 resource blocks on the left and the right sides respectively, wherein the distribution of 242 resource blocks in the frequency domain resources per 40 MHz bandwidth is similar to the distribution of the 242 resource blocks shown in the fourth layer in FIG. 13 . Here, in order to avoid redundancy, The detailed description is omitted.

The fifth layer is a distribution map of the 2*242 resource block distribution map and the default resource block (ie, 1*26 resource block located at the center of the frequency domain resource per 80 MHz bandwidth), and is the default at the center of the frequency domain resource located in the 80 MHz bandwidth. There are one 242 resource blocks on the left and right sides of the resource block, and the distribution of 242 resource blocks in the frequency domain resources of each 40 MHz bandwidth is similar to the distribution of the 242 resource blocks shown in the fifth layer in FIG. 13 . Here, in order to avoid redundancy The detailed description is omitted.

Wherein, the frequency domain resource of 160 MHz bandwidth includes 2*996 subcarriers, and may be divided into any resource blocks from the first layer to the sixth layer, and the divided resource blocks are allocated to multiple users, and Each user can only allocate one of the divided resource blocks.

Or, for example, the frequency domain resource spectrum of the 160 MHz bandwidth may be divided into resource blocks in the seventh layer. In this case, the 160 MHz bandwidth frequency domain resource is allocated to one user, and the bandwidth indication information and the following may be used. The single user transmission indication bit indicates the case of resource allocation.

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

The sum is 160 MHz, as shown in the shaded portions in Figures 22 and 23.

Specifically, as shown in FIG. 21, the resource blocks on the left and right sides of the center frequency point of the frequency domain resource of the 160 MHz bandwidth are symmetrically distributed, that is, the center frequency point can serve as a symmetric center of the frequency domain resource of 160 MHz bandwidth.

S304. If the first resource block is not a 4*26 resource block, the sending end sets the first bit of the resource allocation bit sequence as the second identifier, and determines whether the size of the first resource block is greater than the 4*26 resource block.

S305. If the size of the first resource block is smaller than the 4*26 resource block, the sending end sets the second bit of the resource allocation bit sequence as the second identifier, and sets the third bit and the fourth of the resource allocation bit sequence. Bits.

When the first bit is "0", the resource block actually divided is not a 4*26 resource block, and the second bit indicates whether the size of the actually divided resource block is greater than 4*26 resource blocks. When the second bit "0" indicates that the size of the resource block actually divided is smaller than 4*26 resource blocks. Then, the resource block that is actually divided can be determined by using Table 1. Specifically, the third bit and the fourth bit of the resource allocation bit sequence are set by the transmitting end to be 00, 00, which is used to indicate that the frequency domain resource is divided before Four resource blocks are 1*26 a resource block; or, the third bit and the fourth bit of the resource allocation bit sequence are set to 01, 01 is used to indicate that the first three resource blocks into which the frequency domain resource is divided are 1*26 resource blocks, 1*26 resource block and 2*26 resource block; or, the third bit and the fourth bit of the resource allocation bit sequence set by the transmitting end are 10, 10 are used to indicate the first three resources in which the frequency domain resource is divided.

Specifically, the fifth bit of the resource allocation bit sequence is set by the transmitting end as a reserved bit. The transmitting end sets the sixth bit to the eighth bit of the resource allocation bit sequence to 000,000 for indicating the first resource block for single-user transmission; or the transmitting end sets the sixth bit of the resource allocation bit sequence.

The first bit “0” indicates that the spectrum resource on the left side of the symmetric center 1*26 resource block is actually divided into non-4*26 resource blocks, and the second bit “1” indicates that the spectrum resource on the left side of the symmetric center 1*26 resource block is actually divided. More than 4*26 resource blocks. The 3rd to 4th bits "01" indicate that the spectrum resource on the left side of the symmetric center 1*26 resource block is actually divided into 2*242 resource blocks. The last three bits "110" indicate that the number of stations actually transmitted on the 2*242 resource block is 7.

When Y is 0, the following "110" indicates that the number of stations actually transmitted on the 2*242 resource block is 7, and when Y is 1, the last 3 bits are reserved. The value of Y indicates that the meaning can also be reversed.

The allocation bit sequence is "0010 0110", and the two 20M spectrum resource blocks are actually divided into 2*242 resource blocks (also referred to as 484 resource blocks), and the number of stations transmitted on the resource block is 7.

Exemplarily, as shown in FIG. 27, the spectrum resource block of the 80 MHz bandwidth is actually divided into resource blocks, and the resource allocation bit sequence generated by the first 20 MHz bandwidth spectrum resource is “1000 1000”, and the second 20 MHz bandwidth The resource allocation bit sequence generated by the spectrum resource is “0100 Y 000”, and the resource allocation bit sequence generated by the spectrum resources of the third and fourth 20 MHz bandwidths is “0101 Y 101”.

When Y is 1, the following "110" indicates that the number of stations actually transmitted on the 2*242 resource block is 6, and when Y is 0, the last 3 bits are reserved. Y value indication Meaning can also be reversed.

The resource allocation bit sequence generated after the first 20 MHz spectrum resource block shown in FIG. 27 is divided into 97 in the resource allocation bit sequence 1 in the table, indicating that the resource allocation bit sequence generated after the spectrum resource block is divided is “ 1000 1000”, 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), and the number of stations transmitted on two 4*26 resource blocks Both are 1.

There are a plurality of resource allocation bit sequences in Table 3 as reserved sequences, and there are 80 reserved sequences in Table 3. In addition, if the number of stations transmitted per 20M is at most 9, then the numbers in Table 3 are 104, 119-120, 134-136, 149-152, 164-168, 179-184, 194-200, 209-216.

At this time, there are 124 reserved sequence numbers, that is, 132 resource allocation bit sequences indicating that the spectrum resource block is actually divided, wherein the resource block indicating that the spectrum resource block is actually divided has a bit sequence of the intermediate 1*26 resource block. There are 108, and the resource block indicating that the spectrum resource block is actually divided does not contain the intermediate 1*26 resource block. There are 32 kinds of 242(n), 484(n), and 996(n) in Table 3.

The present invention uses a reserved bit to indicate whether a 1*26 resource block is used (whether or not it is allocated to a station), since the resource block in which the indicated spectrum resource block is actually divided has 108 bit sequences of intermediate 1*26 resource blocks, so corresponding 108 reserved bits are required to indicate the actual division of the spectrum in 108 above. The intermediate resource block 1*26 resource block in the case is not used. As shown in Table 4, a separate "x" in the table indicates that the intermediate resource block 1*26 resource block is not used.

In Table 4, the resource allocation bit sequence 1 and the resource allocation bit sequence 2 are the same as the table 3, but the reserved sequence is used to indicate that the intermediate resource block 1*26 resource block in the case where the spectrum is actually divided is not used, wherein the actual division of the spectrum The case where the intermediate resource block 1*26 resource block in the case is not used is the shaded portion of the "resource block (from left to right) actually divided" 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 both selected, that is, the protocol specifies or one of the resource allocation bit sequences stored in the product should be stored. , or other possible deformations. For a resource block that is actually divided, only one resource allocation bit sequence (or sequence) is associated with it, so that the receiving end can learn the actual divided resource block according to the resource allocation bit sequence.

In Fig. 41c, the first exit of Fig. 41a is used as an entry, illustrating 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 resource block (also referred to as 2*996 resource block) corresponding to the maximum bandwidth of 160 MHz is not indicated in the HE-SIGA field, "'0111, ---''→2x996 resource block or reserved sequence" in Figure 41c is 2x996 resource block"; if the resource block 2x996 resource block corresponding to the maximum bandwidth 160MHz (also called 2*996 resource block) is indicated in the HE-SIGA field, "0111,----'→2x996 resource block in Figure 41c Or a reserved sequence" is a reserved sequence, wherein the reserved sequence can be used to indicate retention A source allocation bit sequence (such as a special resource allocation sequence indicating a 484 resource block or a special resource allocation sequence indicating a 996 resource block) carries the site information corresponding to the resource allocation bit sequence in the 20M HE-SIGB in which the resource allocation bit sequence is located. The number is 0. If you use '0111, 0yyy', the reserved sequence can also be used for other indications.

It will be understood that the above-described flowcharts of Figs. 41a, 41b and 41c are one of the examples. If the first identifier and the second identifier of each bit in the resource allocation sequence are different, the corresponding value of the flowchart will be changed accordingly, similar to the possible variant of the resource allocation sequence in Table 3 or Table 4. For example, the first identifier of the fifth bit takes the value 0 and the second identifier takes the value 1. The first bit of the other bit takes the value 1 and the second identifier takes the value 0. The resource allocation bit sequence generated after the spectrum resource block is divided is a table. The resource allocation bit sequence 2 in 3; the first identifier of all the bits takes the value 1 and the second identifier takes the value 0, and the resource allocation bit sequence generated after the spectrum resource block is divided is the resource allocation bit sequence 1 in Table 3.

Example 4

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

Except for MU-MIMO transmission, the number of stations that are actually divided into resource blocks is 1. If it is MU-MIMO transmission, the number of stations that are actually divided into resource blocks is at most 8, and the minimum is 2. In the embodiment of the present invention, the minimum resource block for performing MU-MIMO transmission is 242 resource blocks, so the number of stations whose resource block size is smaller than 242 resource blocks defaults to 1, and the number of resource blocks greater than or equal to 4*26 is uncertain and minimum. It is 1, and the maximum is 8.

As shown in FIG. 28, the method for generating resource scheduling information by using the first identifier is 1 and the second identifier is 0, and the method includes:

S401. The sender acquires at least one resource block in which the frequency domain resource is divided.

S402. The transmitting end generates a resource allocation bit sequence according to at least one resource block that is divided by the frequency domain resource.

Wherein, if the first bit, the second bit, and the third bit of the resource allocation bit sequence are the first identifier, the first resource block to which the frequency domain resource is 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, the second ratio If the special bit is the second identifier, the first two resource blocks in 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, the second bit and The third bit is the second identifier, and the first three resource blocks that are divided into frequency domain resources are 2*26 resource blocks, 1*26 resource blocks, and 1*26 resource blocks in turn; or, if the resource allocation bit sequence The first bit and the second bit are the second identifier, and the third bit is the first identifier, and the first three resource blocks that are divided into the frequency domain resources are 1*26 resource blocks and 1*26 resources in sequence. a block and a 2*26 resource block; 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 of the frequency domain resource are divided 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 frequency domain resources are divided. The first resource block is a 2*242 resource block; or, if the resource allocation bit sequence is 010, Then, the first resource block in which the frequency domain resource is divided is 996 resource blocks.

Further, if the resource allocation bit sequence is 011, 110 or 010, the transmitting end sets the fourth bit to the sixth bit of the resource allocation bit sequence to 000,000 for indicating the first resource block for single-user transmission. Or, the transmitting end sets the fourth bit to the sixth bit of the resource allocation bit sequence to 001, 001 is used to indicate that the first resource block performs multi-user multiple input multiple output technology MU-MIMO transmission, and uses the first The number of stations of the resource block is 2; or, the sender sets the fourth bit to the sixth bit of the resource allocation bit sequence to be 010, 010, which is used to indicate that the first resource block performs multi-user MIMO technology. - MIMO transmission, and the number of stations using the first resource block is 3; or, the transmitting end sets the fourth bit to the sixth bit of the resource allocation bit sequence to 011, 011 is used to indicate the first resource block Multi-user MIMO-MIMO transmission, and the number of stations using the first resource block is 4; or, the transmitter sets the fourth bit to the sixth bit of the resource allocation bit sequence to 100,100. Used to indicate a resource block performs multi-user multiple input multiple output technology MU-MIMO transmission, and the number of stations using the first resource block is 5; or, the transmitting end sets the fourth bit to the sixth bit of the resource allocation bit sequence 101, 101 is used to indicate that the first resource block performs multi-user multiple input multiple-output technology MU-MIMO transmission, and the number of stations using the first resource block is 6; or, the transmitting end sets the fourth of the resource allocation bit sequence The bit to the sixth bit is 110, 110 is used to indicate that the first resource block performs multi-user multiple input multiple output technology MU-MIMO transmission, and the number of stations using the first resource block is 7; or, the sender setting Resource The fourth bit to the sixth bit of the allocated bit sequence is 111, 111 is used to indicate that the first resource block performs multi-user multiple input multiple output MU-MIMO transmission, and the number of stations using the first resource block is 8.

As shown in FIG. 29, a frequency resource of 20 MHz bandwidth may be divided into nine 1*26 resource blocks.

The present invention proposes to use a baffle method to indicate a combination of frequency resource division. The positions of the corresponding six arrows in FIG. 29 are respectively set to 1 bit. When the bit is "1", it indicates that two adjacent resource blocks are connected. Together, it can be combined into a larger resource block than the 1*26 resource block; when the bit is "0", it means that the adjacent two resource blocks are separated. Referring to the resource block location map that may be divided in FIG. 8, the intermediate 1*26 resource block may not be combined with other resource blocks into other resources, so that there is no arrow on the side of the resource block 2.

As shown in FIG. 30, the resource allocation information is indicated as “111 111”, indicating that the first 1*26 resource blocks on the left side of the intermediate 1*26 resource block are combined into a 4*26 resource block, and the middle 1*26 resource block is right. Four 1*26 resource blocks are combined to form a 4×26 resource block.

As shown in FIG. 31, the resource allocation information is indicated as “101 111”, indicating that two 1*26 resource blocks on the left side of the intermediate 1*26 resource block are combined into a 2*26 resource block, and the next two 1*s are 26 resource blocks are grouped together into 2*26 resource blocks, and the first 1*26 resource blocks on the right side of the middle 1*26 resource block are combined to form a 4*26 resource block.

As shown in FIG. 32, the resource allocation information is indicated as “101 000”, indicating that two 1*26 resource blocks on the left side of the intermediate 1*26 resource block are combined to form a 2*26 resource block, followed by two 1*s. 26 resource blocks are grouped together into 2*26 resource blocks, and the first 1*26 resource blocks on the right side of the middle 1*26 resource block are not connected together and are divided into independent 1*26 resource blocks.

Referring to FIG. 8, the indication bit to the left or right of the intermediate resource block may not be "011", "110" or "010". For example, if the left bit of the intermediate resource block indicates the bit "110", it means that the first 3 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. So we can use these special indicator bits to indicate other meanings. For example, the frequency domain resource of the 20 MHz bandwidth is divided into 242 resource blocks by using "011XXX", wherein a 3-bit binary number "X" is used to indicate the number of stations transmitted on the 242 resource block, and "000" indicates the number of stations. Is 1, "001" means the number of sites is 2, and so on.

For frequency domain resources with a bandwidth greater than 20 MHz, such as frequency domain resources of 40 MHz bandwidth, The frequency domain resources into two 20 MHz bandwidths are respectively indicated by the actually divided resource blocks, but one more resource block type that may be divided, such as a 2*242 resource block. Here, a special indication bit is used to indicate the situation, such as "110XXX" indicating that the 20MHz bandwidth frequency domain resource is combined with the adjacent 20MHz bandwidth frequency domain resource into 2*242 resource blocks. The "010XXX" indicates that the 20MHz bandwidth frequency domain resource is combined with the adjacent two 20MHz bandwidth frequency domain resources into one 996 resource block.

Exemplarily, as shown in FIG. 33, the frequency domain resource of 40 MHz bandwidth is actually divided. The frequency domain resource indication bit sequence of the first 20 MHz bandwidth is “011 001”, and the frequency domain resource of the second 20 MHz bandwidth is shown. The indication bit sequence is also "011 001".

Exemplarily, as shown in FIG. 34, the frequency domain resource of the 80 MHz bandwidth is actually divided. The frequency domain resource indication bit sequence of the first 20 MHz bandwidth is “111 111”, and the frequency domain resource of the second 20 MHz bandwidth is shown. The bit sequence "110 011" is indicated, the frequency domain resource indication bit sequence of the third 20 MHz bandwidth is "011 000", and the frequency domain resource indication bit sequence of the fourth 20 MHz bandwidth is also "011 000".

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

Example 5

If the resource scheduling information includes only the resource allocation bit sequence, the site information is not included. That is to say, which resource blocks are not included for the MU-MIMO transmission indication, and which resources are used for the single-user transmission indication. The smallest resource block in which MU-MIMO transmission is considered here is a 4*26 resource block. The embodiment of the present invention proposes to additionally add a bit to indicate the number of stations transmitted on the resource block, and put it in the site information.

The encoding method of HE-SIG-B is separately coded for the information of K stations. There are two ways, one is that the public parameters are partially coded independently, and the information of each K site is encoded separately, as shown in FIG. Another way is that the public parameters are encoded together with the information of the former K site, and the information of each K site is encoded separately, as shown in FIG. Each of the site information groups contains a fixed number of bits and is equal. The public information parameter group may have the same size as the site 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, in addition to the first independent coding block, optionally adding 3 bits in a specified coding block indicates that the transmission is actually performed on a 4*26 resource block or a larger resource block. The number of sites, where the bit position is not limited, is better placed before the code block. For example, 000 means that 1 site participates in transmission, 001 means 2 sites participate in transmission, and so on. More than one station participates in the transmission, indicating that MU-MIMO transmission is performed on the resource block, that is, 3-bit bits "001-111" indicate MU-MIMO transmission, and "000" indicates single-site transmission. The bits indicating the number of stations transmitted on the 4*26 resource block or the larger resource block are placed in the designated coding block, so that the receiver can know how many bits each block has, so that it can be correctly decoded. When there are 2 4*26 resource blocks in the 20M, the number of stations in the specified coding block in the 20M is increased by 6 bits to indicate the number of stations on the resource block. When 20M contains one 4*26 resource block or 242 resources. The block or the adjacent 20 MHz bandwidth frequency domain resources are combined into a larger resource block, and the number of stations on the resource block is indicated by adding 3 bits in the coded block within the frequency domain resource of the 20 MHz bandwidth.

Exemplarily, the frequency domain resource of the 20 MHz bandwidth is divided into two 4*26 resource blocks, and each resource block needs to add 3 bits to indicate the number of stations transmitted on the resource block. In one implementation, the transmitting end places the 6 bits. The front of the second code block.

The receiving end first decodes the first block of coded blocks (the number of bits included in the first block of coded blocks is known), and the resource information of the first block of codes is used to learn that there are two 4*26 resource blocks. Therefore, the receiver knows that the second block of code blocks is additionally increased by 6 bits, so that it can be effectively decoded.

Exemplarily, the frequency domain resource of the 20 MHz bandwidth is divided into one 4*26 resource block, and three bits need to be added to indicate the number of stations transmitted on the resource block. In one implementation, the sender places the 3 bits into the second code. The front inside the block.

The receiving end first decodes the first block of coded blocks (the number of bits included in the first block of coded blocks is known), and the resource information of the first block of codes is known to contain one 4*26 resource block. Therefore, the receiver knows that the second block of code blocks is additionally increased by 3 bits, so that it can be effectively decoded.

Exemplarily, the frequency domain resource of the 80 MHz bandwidth is divided into: the first 20 MHz bandwidth frequency domain resource contains two 4*26 resource blocks, and the transmitting end places the 6 bits in the first 20 MHz bandwidth frequency domain resource. The front of the two coded blocks. The frequency domain resource of the second 20 MHz bandwidth divided contains one 242 resource block, and the transmitting end places the three bits in front of the second coding block in the frequency domain resource of the second 20 MHz bandwidth. The frequency domain resource of the third 20 MHz bandwidth divided and the frequency domain resources of the adjacent 20 MHz bandwidth are divided into 2*484 resource blocks, and the transmitting end places the 3 bits in the frequency domain resource of the third 20 MHz bandwidth. The front of the second code block. Fourth divided The frequency domain resource of 20 MHz bandwidth is divided into 2*484 resource blocks together with the adjacent frequency domain resources of 20 MHz bandwidth, and the transmitting end places the 3 bits into the second coding block in the frequency domain resource of the fourth 20 MHz bandwidth. The front.

The receiving end first decodes the first block of coding blocks in the frequency domain resource of each 20 MHz bandwidth (the number of bits included in the first block of coding blocks is known), and the resource allocation information of the first block is used to learn that the resource block contains 4*26 resources. And the number of larger resource blocks. Therefore, the receiver knows how many extra bits are added to the second block of code blocks, so that it can be effectively decoded.

It should be noted that the above embodiment is not limited to adding bit information indicating the number of stations on the 4*26 resource block and the larger resource block in the second coding block. It can also be in other coded blocks, but it needs to be known at the receiving end.
