Description

Resource scheduling method, device and equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, and a device for resource scheduling.

Background

With the development of technologies such as Orthogonal Frequency Division Multiple Access (OFDMA) transmission technology, multi-User input/output (MU-MIMO), etc., current communication systems have been able to support multi-User transmission, i.e., support Multiple stations to transmit and receive data simultaneously.

However, the above-mentioned multi-user transmission (for example, including OFDMA, MU-MIMO or a hybrid transmission of OFDMA and MU-MIMO) needs to provide a solution for how to perform resource scheduling for multiple users.

A resource scheduling scheme is known, in which a resource block in a frequency domain resource to be allocated is indicated by a bit sequence, that is, 1 bit in the bit sequence indicates allocation of 1 sub-resource block (1 sub-resource block includes 1 × 26 sub-carriers), and a switch between 0 and 1 in the bit sequence indicates that the resource block indicated by a bit before switching and the resource block indicated by a bit after switching are allocated to different users.

For example, in the case that the bandwidth of the frequency domain resource required to be allocated is 20 megahertz (MHz), including 9 sub-resource blocks, a bit sequence of 9 bits is required to be used for resource allocation indication, and as the bandwidth increases, the length of the bit sequence is also continuously increased, that is, the resource scheduling scheme in the prior art needs to occupy a large amount of transmission resources to transmit the bit sequence.

It is therefore desirable to provide a technique that can support a reduction in the overhead of resource scheduling on transmission resources.

s120, sending the resource scheduling information to a receiving end;

the method 100 can be applied to various communication systems that implement multi-user transmission by means of resource scheduling, for example, a system that performs communication by means of OFDMA or MU-MIMO.

Also, the method 100 may be applied to a Wireless Local Area Network (WLAN), such as a Wireless Fidelity (Wi-Fi).

Fig. 2 is a schematic diagram of a WLAN system. As shown in fig. 2, the WLAN system includes one or more access points AP21 and one or more stations STA 22. And carrying out data transmission between the access point and the station, wherein the station determines the resource scheduled to the station according to the lead code sent by the access point, and carrying out data transmission between the station and the access point based on the resource.

Optionally, the sending end is a network device, and the receiving end is a terminal device.

Specifically, as the sending end device, a network side device in the communication system may be enumerated, for example, an Access Point (AP) in the WLAN, where the AP may also be referred to as a wireless Access Point, a bridge, a hotspot, or the like, and may Access a server or a communication network.

As the receiving end device, a terminal device in the communication system may be enumerated, for example, a Station (STA) in the WLAN, the STA may also be referred to as a user, and may be a wireless sensor, a wireless communication terminal or a mobile terminal, such as a mobile phone (or referred to as a "cellular" phone) and a computer having a wireless communication function. For example, wireless communication devices, which may be portable, pocket-sized, hand-held, computer-embedded, wearable, or vehicle-mounted, exchange voice, data, etc., communication data with a radio access network.

It should be understood that the above-listed systems to which the method 100 of the embodiments of the present invention is applied are merely exemplary, and the present invention is not limited thereto, and for example, it is also possible to list: global System for mobile communications (GSM), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), General Packet Radio Service (GPRS), and Long Term Evolution (LTE).

Accordingly, the network device may be a Base Station (BTS) in GSM or CDMA, a Base Station (NodeB) in WCDMA, an evolved node B (eNB or e-NodeB) in LTE, a Micro cell Base Station (Micro), a Pico Base Station (Pico), a home Base Station (femtocell), or a femto Base Station (femto), which is not limited in the present invention. The Terminal device may be a Mobile Terminal (Mobile Terminal), a Mobile user equipment, etc., such as a Mobile telephone (or so-called "cellular" telephone).

The rules for resource block size partitioning in WLAN systems are: one resource unit is 26 subcarriers.

As shown in fig. 3, taking a 20 megahertz (MHz) bandwidth as an example, the number of discrete fourier transform/inverse discrete fourier transform (DFT/IDFT) points in a data symbol portion in the WLAN system is 256, that is, there are 256 subcarriers, where subcarriers-1, 0, 1 are Direct Current (DC), and left subcarriers-122 to subcarrier-2 and right subcarriers 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. Therefore, the 242 subcarriers normally used for carrying data information are divided into 9 sub-resource blocks, each sub-resource block includes 26 subcarriers, then 8 unused subcarriers remain, and the sub-resource block located at the center of the bandwidth spans DC (i.e., includes subcarriers-1, 0, 1), and the method 100 of the embodiment of the present invention mainly relates to the allocation of the 242 subcarriers used for carrying data information.

The frequency domain resources of different bandwidths can include different types of resource blocks (which may also be referred to as resource blocks). Specifically, the next generation protocol followed by the wireless local area network stipulates the possibly divided resource block positions (resource distribution map) for various frequency domain resources to be allocated (20MHz, 40MHz, 80MHz, or 160MHz), the transmitting end generates and transmits resource scheduling information, the resource scheduling information includes a bit sequence for indicating the divided resource blocks to be allocated, and the receiving end can know which resource blocks the frequency domain resources to be allocated are divided into by reading the bit sequence.

In addition, the resource scheduling information may further include information of a scheduled receiving end corresponding to the divided resource blocks, so that the receiving end reads the resource scheduling information to realize uplink and downlink information transmission in the resource blocks allocated to the receiving end.

The following describes in detail the possible divided resource block positions (refer to the resource distribution diagram shown in fig. 4, fig. 5 or fig. 6) for various frequency domain resources to be allocated, which are agreed in the next generation protocol.

1. Frequency domain resources 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.

Specifically, as shown in fig. 4, 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 resource block of a 1 × 26 type, i.e., a resource block spanning DC (i.e., 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 particular by the present invention.

In addition to the default resource block located at the default position, the frequency domain resources of 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, respectively, that is:

a resource block of type 1 × 26, the smallest resource block that may be partitioned in a 20MHz bandwidth, means that one resource block is composed of one sub-resource block (i.e., 26 subcarriers).

A2 × 26 type of resource block means that one resource block is composed of two sub-resource blocks (i.e., 2 × 26 subcarriers).

A4 × 26 type of resource block means that one resource block is composed of four sub-resource blocks (i.e., 4 × 26 subcarriers).

242 types of resource blocks, the largest resource block that may be partitioned in a 20MHz bandwidth, means that one resource block is made up of 242 subcarriers.

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

As shown in fig. 4, for simplicity of describing the resource block locations that may be partitioned, the resource block distribution of the 20MHz bandwidth is depicted or described as 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 the 20MHz bandwidth), and there are 41 × 26 resource blocks, i.e., resource blocks located at resource block positions (hereinafter simply referred to as positions) #7 to #10 and #11 to #14 shown in fig. 4, 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 20MHz bandwidth), and 2 resource blocks of 2 × 26 types, i.e., resource blocks located at positions #1 to #4 shown in fig. 4, are located on both 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 20MHz bandwidth), and there are 14 × 26 resource blocks, i.e., resource blocks located at position #5 and position #6 shown in fig. 4, on the left and right sides of the default resource block located at the center.

The fourth layer is a resource block profile of type 242.

In one example, the frequency domain resource of the 20MHz bandwidth (i.e., an example of the frequency domain resource to be allocated) includes 242 subcarriers, and may be divided into any resource blocks in the first layer to the third layer in fig. 4, the divided resource blocks are allocated to a plurality of users, and each user can only allocate one of the divided resource blocks.

Or, in another 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.

The resource scheduling method of the present invention mainly relates to a case where frequency domain resources of a 20MHz bandwidth are combined by any resource block in the first layer to the third layer and allocated to a plurality of users.

For example, fig. 7 shows an example of allocation of frequency domain resources of 20MHz bandwidth, and as shown in fig. 7, the frequency domain resources are divided (in order from left to right in fig. 7) into 1 resource block of 2 × 26 type (i.e., resource block #1), 3 resource blocks of 1 × 26 type (i.e., resource block #2, resource block #3, and resource block #0, where resource block #0 is a default resource block), and 1 resource block of 4 × 26 type (i.e., resource block # 4).

For another example, fig. 8 shows another example of allocation of frequency domain resources of 20MHz bandwidth, and as shown in fig. 8, the frequency domain resources (in order from left to right in fig. 9) are divided into 9 1 × 26 resource blocks, where the resource block located at the center of the 20MHz bandwidth (i.e., the resource block indicated by the dashed-line box in fig. 8) is the default resource block.

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

Specifically, as shown in fig. 4, 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 resource blocks located at 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 20MHz bandwidth.

2. Frequency domain resources for 40MHz bandwidth

The frequency domain resources of the 40MHz bandwidth may be regarded as being composed of two frequency domain resources of 20MHz, and accordingly, each frequency domain resource of the 20MHz bandwidth may include a default resource block located at the center of the 20MHz bandwidth (i.e., a resource block located at a default position), and a configuration and an allocation manner of the default resource blocks (two in total) in the 40MHz bandwidth are similar to those of the default resource blocks in the 20MHz bandwidth, and here, detailed descriptions thereof are omitted to avoid redundancy.

In addition to the default resource block located at the default position, the frequency domain resource of the 40MHz bandwidth further includes the following five types of resource blocks located on the left side or the right side of the default resource block, respectively, that is:

a 1 × 26 type of resource block, the smallest resource block that may be partitioned in a 40MHz bandwidth, means that one resource block is composed of one sub-resource block (i.e., 26 subcarriers).

A2 × 26 type of resource block means that one resource block is composed of two sub-resource blocks (i.e., 2 × 26 subcarriers).

A4 × 26 type of resource block means that one resource block is composed of four sub-resource blocks (i.e., 4 × 26 subcarriers).

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

The largest possible resource block to be divided in the 2 × 242, 40MHz bandwidth means that one resource block is composed of 2 × 242 subcarriers.

As shown in fig. 5, for simplicity of describing the resource block locations that may be partitioned, the resource block distribution of the 40MHz bandwidth is depicted or described as 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 20MHz bandwidth), and there are 41 × 26 resource blocks on the left and right sides of each default resource block, where the distribution of 8 1 × 26 resource blocks in each 20MHz bandwidth is similar to the distribution of 1 × 26 resource blocks shown in the first layer in fig. 4, 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 located at the center of each 20MHz bandwidth), and there are 2 × 26 resource blocks (e.g., position # E and position # F in fig. 5) on the left and right sides of each default resource block, respectively, 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. 4, and here, to avoid redundant description, detailed description thereof is omitted.

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 position of each 20MHz bandwidth), and there are 14 × 26 resource blocks (e.g., position # C and position # D in fig. 5) on the left and right sides of each default resource block, respectively, where the distribution of the 4 × 26 resource blocks in each 20MHz bandwidth is similar to the distribution of the 4 × 26 resource blocks shown in the third layer in fig. 4, and here, to avoid redundant description, detailed description thereof is omitted.

The fourth layer is a 242-type resource block distribution diagram, and there are 1 resource block of 242 types, i.e., the resource block located at position # a and position # B shown in fig. 5, on each of the left and right sides of the center frequency point (i.e., subcarrier 0) located at 40 MHz.

The fifth layer is a4 x 242 type resource block profile.

In one example, the frequency domain resource of the 40MHz bandwidth (i.e., an example of the frequency domain resource to be allocated) includes 484 subcarriers, and may be divided into any resource blocks in the first layer to the fourth layer in fig. 5, the divided resource blocks are allocated to a plurality of users, and each user can allocate only one of the divided resource blocks.

Or, in another 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.

The resource scheduling method of the present invention mainly relates to a case where frequency domain resources of a 40MHz bandwidth are combined by any resource block in first to fourth layers and allocated to a plurality of users.

For example, fig. 9 shows an example of allocation of frequency domain resources of a 40MHz bandwidth, and as shown in fig. 9, the frequency domain resources are divided (sequentially from left to right in fig. 9) into 1 resource block of 4 × 26 type (i.e., resource block #1 '), 3 resource blocks of 1 × 26 type (i.e., resource block # 0', resource block #2 ', and resource block # 3'), 1 resource block of 2 × 26 type (i.e., resource block #4 '), and 9 resource blocks of 1 × 26 type, where the resource block shown by a dotted frame in fig. 9 is a default resource block, e.g., resource block # 0'.

For another example, fig. 10 shows another example of allocation of frequency domain resources of 40MHz bandwidth, and as shown in fig. 10, the frequency domain resources (in order from left to right in fig. 10) are divided into 14 × 26 resource block (i.e., resource block #1 "), 51 × 26 resource blocks (i.e., resource block # 0", resource block #2 ", resource block # 3", resource block #4 ", resource block # 5") and 1 242 resource blocks (i.e., resource block #6 "), where the resource blocks shown by the dotted line boxes in fig. 10 are default resource blocks, e.g., resource block # 0".

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

Specifically, as shown in fig. 4, 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.

3. Frequency domain resources 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.

Specifically, as shown in fig. 6, 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 a 1 × 26 type of resource block, i.e., a resource block spanning DC (i.e., 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 of 1 × 26 type 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.

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

In addition to the default resource block located at the default position, 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 block, respectively, that is:

a resource block of type 1 × 26, the smallest resource block that may be divided in an 80MHz bandwidth, means that one resource block is composed of one sub-resource block (i.e., 26 subcarriers).

A2 × 26 type of resource block means that one resource block is composed of two sub-resource blocks (i.e., 2 × 26 subcarriers).

A4 × 26 type of resource block means that one resource block is composed of four sub-resource blocks (i.e., 4 × 26 subcarriers).

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

The 2 × 242 type resource block indicates that one resource block is composed of 2 × 242 subcarriers.

A 996 type resource block, the largest resource block that may be partitioned in an 80MHz bandwidth, means that one resource block is composed of 996 subcarriers.

For simplicity of describing the resource block locations that may be partitioned, the resource block distribution of the 40MHz bandwidth is depicted or described as 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 20MHz bandwidth and 1 × 26 resource blocks located at the center of each 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 20MHz bandwidth, where the distribution of the 1 × 26 resource blocks in each 20MHz bandwidth is similar to the distribution of the 1 × 26 resource blocks shown in the first layer in fig. 4, 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 located at the center of each 20MHz bandwidth and 1 × 26 resource blocks located at the center of each 80MHz bandwidth), and there are 2 × 26 resource blocks on the left and right sides of the default resource block at the center of each 20MHz bandwidth, where the distribution of the 2 × 26 resource blocks in each 20MHz bandwidth is similar to the distribution of the 2 × 26 resource blocks shown in the second layer in fig. 4, 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 each 20MHz bandwidth and 1 × 26 resource blocks located at the center of each 80MHz bandwidth), and there are 14 × 26 resource blocks (e.g., position # e and position # f in fig. 6) on the left and right sides of the default resource blocks at the center of each 20MHz bandwidth, respectively, where the distribution of the 4 × 26 resource blocks in each 20MHz bandwidth is similar to the distribution of the 4 × 26 resource blocks shown in the third layer in fig. 4, and here, detailed descriptions thereof are omitted to avoid redundancy.

The fourth layer is a distribution diagram of 242 types of resource blocks and a distribution diagram of default resource blocks (i.e., 1 × 26 types of resource blocks located at the center position of the 80MHz bandwidth), there are 1 resource block of 242 types, i.e., resource blocks located at the position # c and the position # d shown in fig. 6, on the left and right sides of the center frequency point of each 40MHz, respectively, where the distribution of the resource blocks of 242 types in each 40MHz bandwidth is similar to the distribution of the resource blocks of 242 types shown in the fourth layer in fig. 5, and a detailed description thereof is omitted here to avoid redundant description.

The fifth layer is a distribution diagram of 2 × 242 types of resource blocks and a distribution diagram of default resource blocks (i.e., 1 × 26 types of resource blocks located at the center position of the 80MHz bandwidth), and there are 1 resource block of 242 types, i.e., resource blocks located at the position # a and the position # b shown in fig. 6, on the left and right sides of the default resource block located at the center position of the 80MHz bandwidth, respectively, where the distribution of the resource blocks of 242 types in each 40MHz bandwidth is similar to the distribution of the resource blocks of 242 types shown in the fifth layer in fig. 5, and here, detailed descriptions thereof are omitted to avoid redundancy.

The sixth layer is a 996 type resource block profile.

In one example, the frequency domain resource of the 80MHz bandwidth (i.e., an example of the frequency domain resource to be allocated) includes 996 subcarriers, and may be divided into any resource blocks from the first layer to the fifth layer in fig. 6, the divided resource blocks are allocated to a plurality of users, and each user can only allocate one of the divided resource blocks.

Or, in another 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, which will be described later.

The resource scheduling method 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 distributed to a plurality of users.

For example, fig. 11 shows an example of frequency domain resources with a bandwidth of 80MHz, and as shown in fig. 11, the frequency domain resources (in order from left to right in fig. 11) are divided into one resource block of 4 × 26 type, and one resource block of 2 × 242 type, where the resource block shown by a dashed box in fig. 11 is a default resource block.

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

Specifically, as shown in fig. 4, 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 resource blocks located at 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.

4. Frequency domain resources for 160MHz bandwidth

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

In addition to the default resource block located at the default position, the frequency domain resources of the 160MHz bandwidth further include the following seven types of resource blocks located on the left side or the right side of the default resource block, respectively, that is:

a resource block of type 1 × 26, the smallest resource block that may be divided in an 80MHz bandwidth, means that one resource block is composed of one sub-resource block (i.e., 26 subcarriers).

A2 × 26 type of resource block means that one resource block is composed of two sub-resource blocks (i.e., 2 × 26 subcarriers).

A4 × 26 type of resource block means that one resource block is composed of four sub-resource blocks (i.e., 4 × 26 subcarriers).

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

The 2 × 242 type resource block indicates that one resource block is composed of 2 × 242 subcarriers.

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

A resource block of 2 × 996 type, the largest resource block that may be divided in a 160MHz bandwidth, means that one resource block is composed of 2 × 996 subcarriers.

For simplicity of describing the resource block locations that may be partitioned, the resource block distribution of the 160MHz bandwidth is depicted or described as 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 20MHz bandwidth and 1 × 26 resource blocks located at the center of each 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 20MHz bandwidth, where the distribution of the 1 × 26 resource blocks in each 20MHz bandwidth is similar to the distribution of the 1 × 26 resource blocks shown in the first layer in fig. 4, 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., 1 × 26 resource blocks located at the center of each 20MHz bandwidth and 1 × 26 resource blocks located at the center of each 80MHz bandwidth), and there are 2 × 26 resource blocks on the left and right sides of the default resource block at the center of each 20MHz bandwidth, where the distribution of the 2 × 26 resource blocks in each 20MHz bandwidth is similar to the distribution of the 2 × 26 resource blocks shown in the second layer in fig. 4, and here, to avoid redundant description, detailed description thereof is omitted.

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 20MHz bandwidth and 1 × 26 resource blocks located at the center 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 each 20MHz bandwidth, where the distribution of the 4 × 26 resource blocks in each 20MHz bandwidth is similar to the distribution of the 4 × 26 resource blocks shown in the third layer in fig. 4, and here, detailed descriptions thereof are omitted to avoid redundant description.

The fourth layer is a distribution diagram of 242 types of resource blocks and a distribution diagram of default resource blocks (i.e., 1 × 26 types of resource blocks located at the center of each 80MHz bandwidth), and there are 1 resource blocks of 242 types on the left and right sides of the center frequency point of each 40MHz, where the distribution of the resource blocks of 242 types in each 40MHz bandwidth is similar to the distribution of the resource blocks of 242 types shown in the fourth layer in fig. 5, and here, detailed descriptions thereof are omitted to avoid redundancy.

The fifth layer is a distribution diagram of 2 × 242 types of resource blocks and a distribution diagram of default resource blocks (i.e., 1 × 26 types of resource blocks located at the center position of each 80MHz bandwidth), there are 1 resource block of 242 types on the left and right sides of the default resource block located at the center position of each 80MHz, and the distribution of the resource blocks of 242 types in each 40MHz bandwidth is similar to the distribution of the resource blocks of 242 types shown in the fifth layer in fig. 5, and here, detailed descriptions thereof are omitted to avoid redundancy.

The sixth layer is a distribution diagram of 996 types of resource blocks and a distribution diagram of default resource blocks (i.e., 1 × 26 types of resource blocks located at the center of each 80MHz bandwidth), there are 1 resource blocks of 996 types on the left and right sides of the center frequency point located at 160MHz, and the distribution of 242 types of resource blocks in each 80MHz bandwidth is similar to the distribution of 996 types of resource blocks shown in the sixth layer in fig. 6, and here, detailed descriptions thereof are omitted to avoid redundancy.

The seventh layer is a2 x 996 type resource block profile.

In one example, the frequency domain resource of the 160MHz bandwidth (i.e., an example of the frequency domain resource to be allocated) 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 allocate only one of the divided resource blocks.

Or, in another 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 condition may be indicated by bandwidth indication information and a single-user transmission indication bit described later.

The resource scheduling method of the present invention mainly relates to a case where frequency domain resources of a 160MHz bandwidth are combined by any resource block in first to sixth layers and allocated to a plurality of users.

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

Specifically, as shown in fig. 4, the resource blocks on the left and right sides of the center frequency point of the frequency domain resource with the 160MHz bandwidth are symmetrically distributed, that is, the center frequency point can be 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.

In the embodiment of the present invention, the sending end needs to perform resource scheduling, for example, the receiving end (the number of the receiving ends may be one or more) is notified of resource blocks corresponding to the sending end through resource scheduling information, so that the receiving end can transmit through the resource blocks.

The sender may notify each receiver in the system of the following information via a bit sequence, or bit map (bitmap):

the resource block to be allocated with the frequency domain resource is divided, that is, on the one hand, the number of subcarriers included in each divided resource block, or the type of each divided resource block. On the other hand, the resource block division also includes the position of each resource block in the frequency domain resource to be allocated. In the following embodiments, a simplified resource block division instruction is performed by using resource blocks that may be divided in each bandwidth stipulated by a protocol, for example, the number and position information included in each type of frequency domain resource block in each bandwidth. Therefore, the receiving end can determine each resource block allocated by the transmitting end based on the information, and in combination with the information of the scheduled receiving end, the receiving end can perform subsequent information transmission on the scheduled corresponding resource block.

The following embodiments propose schemes for efficiently indicating the resource block division condition of the frequency domain resource to be allocated (or the bandwidth to be allocated).

Implementation mode one

Optionally, the bit sequence includes a first type of bit group, where the first type of bit group is used to indicate whether a first type of frequency domain resource segment is allocated to a preset number of receiving ends, the first type of bit group includes at least one bit, a frequency domain width of the first type of frequency domain resource segment is 20MHz, and the preset number is greater than 1.

Specifically, as described above in the resource allocation manner agreed in the next generation protocol, the bandwidth of the frequency domain resource to be allocated is an integer multiple of the bandwidth of 20MHz, that is, the frequency domain resource to be allocated may include a plurality of frequency domain segments with a width of 20MHz, and in the embodiment of the present invention, the bit sequence generation at the transmitting end and the bit sequence reading operation at the receiving end may be performed by using the frequency domain segments with a width of 20MHz as a unit.

Each 20MHz frequency domain segment may respectively correspond to a first type bit group in the bit sequence, where a first type bit group may include at least one bit, and one first type bit group is used to indicate whether the corresponding 20MHz frequency domain segment (i.e., the first type frequency domain resource segment) is allocated to a preset number of receiving ends.

Optionally, the preset number is determined according to a frequency domain width of a smallest resource block position except the default position among the resource block positions into which the frequency domain resource to be allocated may be divided.

Specifically, in the embodiment of the present invention, the "preset number" may be determined according to a frequency domain width of a minimum resource block position, other than the default position, agreed in the next generation protocol.

Alternatively, when the frequency domain width of the minimum resource block position is to include 26 consecutive subcarriers, the preset number is 8 or 9.

Specifically, for example, in the resource block position division scheme shown in fig. 4 to 6, the frequency domain width of the minimum resource block position is the frequency domain width corresponding to the consecutive 26 subcarriers, that is, the frequency domain width of the resource block position in the first layer in fig. 4 to 6, and in this case, when the frequency domain segment of 20MHz is allocated in the scheme indicated in the first layer in fig. 4 to 6, the resource blocks other than the default position in the frequency domain segment of 20MHz are allocated to 8 receiving ends.

Further, when the resource block of the default position is independently allocated (i.e., adjacent resource blocks to the left or right of the default position are allocated to different receiving ends), 9 resource blocks including the resource block of the default position in the 20MHz frequency domain segment are allocated to 9 receiving ends;

alternatively, when the resource block of the default position is not allocated independently (i.e. the adjacent resource block to the left or right of the default position is allocated to the same receiving end), 9 resource blocks including the resource block of the default position in the 20MHz frequency domain segment are allocated to 8 receiving ends, it should be noted that when the resource block of the default position is not allocated independently, the scheduling information further includes default resource block allocation information for indicating the allocation condition of the resource block of the default position, and then the information and the resource scheduling process based on the information are described in detail.

Therefore, in the embodiment of the present invention, when the next generation protocol followed by the wireless local area network to which the method 100 is applied stipulates that the size of the minimum resource block, except for the default resource block that is not indicated by the bit sequence, among the resource blocks that may be divided for the frequency domain resources to be allocated is the width corresponding to 26 consecutive subcarriers, one first-type bit group may be used to indicate whether the corresponding 20MHz frequency domain segment is allocated to 8 or 9 receiving ends.

Hereinafter, for convenience of understanding and explanation, the procedure of resource scheduling when resource blocks at the default position are independently allocated will be described without loss of generality.

As an example and not by way of limitation, in the embodiment of the present invention, a first class bit group corresponding to a 20MHz first class frequency domain resource segment may be formed by 1 bit, where the 1 bit is used to indicate whether the 20MHz first class frequency domain resource segment is allocated to 9 (or 8) receiving ends, and in the embodiment of the present invention, a transmitting end and a receiving end may determine, according to pre-negotiation or system specification, a mapping relationship in a case that the first class bit group and the first class frequency domain resource segment are allocated to 9 (or 8) receiving ends, for example:

0 may indicate that the first type of frequency domain resource segment is allocated to 9 (or 8) receiving ends;

a 1 may indicate that the first type of frequency-domain resource segment is not allocated to 9 (or 8) receiving ends.

In addition, in the embodiment of the present invention, the bit sequence may further include bits for indicating the size of each resource block to be allocated, for example, in addition to the first type of bit group, the bit sequence may further include multiple segments of sub-bit sequences, the multiple segments of sub-bit sequences correspond to multiple resource blocks to be allocated in a one-to-one manner, where each segment of sub-bit sequence is composed of one or more consecutive "1" or "0", where consecutive "1" or "0" indicates that the resource block to be allocated corresponding to the segment of sub-bit sequence is given to the same user, and when a bit in the multiple segments of sub-bit sequences changes from 1 to 0 or from 0 to 0, this indicates that the boundary of two resource blocks to be allocated here is present, that is, the resource to be allocated is changed from being allocated to one receiving end to being allocated to another receiving end.

In the embodiment of the present invention, the sub-bit sequences of each length and the resource blocks of the types may have the following mapping relationship:

1 (or 0) represents that the resource block to be allocated is a 1 × 26 type resource block;

11 (or 00) represents that the resource block to be allocated is a2 × 26 type resource block;

111 (or 000) denotes a resource block to be allocated as a4 × 26 type resource block.

The mapping relationship between the sub-bit sequences of each length and the resource blocks of the type listed above is only an exemplary illustration, and the present invention is not limited thereto, for example, when the bandwidth to be allocated with the frequency domain resource is greater than 20MHz (for example, 40MHz, 80MHz, 160MHz, etc.), the following mapping relationship may be included in addition to the mapping relationship between the sub-bit sequences of each length and the resource blocks of the type in the 20MHz described above:

1111 (or 0000) denotes a resource block to be allocated as a 242 type resource block.

For example, fig. 7 shows an example of a resource block division manner of a frequency domain resource to be allocated with a bandwidth of 20MHz, and as shown in fig. 7, the frequency domain resource to be allocated is actually divided into 5 resource blocks to be allocated, that is, sequentially divided into 1 resource block of 2 × 26 type (i.e., resource block #1), 3 resource blocks of 1 × 26 type (i.e., resource block #2, resource block #3, and resource block #0) and 1 resource block of 4 × 26 type (i.e., resource block #4) in the order from left to right in fig. 7, where resource block #0 is a default resource block.

As shown in fig. 7, the first resource block (i.e., resource block #1) in the frequency domain resources to be allocated is a2 × 26 type resource block, and thus, its corresponding sub-bit sequence is 11;

the second resource block (i.e., resource block #2) in the frequency domain resources to be allocated is a 1 × 26 type resource block, and is allocated to a different receiving end from resource block #1, so its corresponding sub-bit sequence is 0;

the third resource block (i.e., resource block #3) in the frequency domain resources to be allocated is a 1 × 26 type resource block, and is allocated to a different receiving end from resource block #2, so its corresponding sub-bit sequence is 1;

the fourth resource block to be allocated (i.e., resource block #0) is a resource block of the default position, and is not indicated by a bit sequence.

The fifth resource block (i.e., resource block #4) of the frequency domain resources to be allocated is a4 × 26 type resource block, and is allocated to a different receiving end from resource block #3, and thus, its corresponding sub-bit sequence is 000.

Since the 20MHz resource to be allocated (i.e. including one first type frequency domain resource segment) shown in fig. 7 is not allocated to 9 (or 8) receiving ends, the corresponding first type bit group to be allocated is 1.

It should be noted that, in the embodiment of the present invention, the position of the first-type bit group in the generated bit sequence may be determined by negotiation in advance between the sending end and the receiving end, or may also be specified by the system, for example, the first-type bit group may be the first T bits (T is the number of bits included in one first-type bit group, and may be 1 in this example) in the generated bit sequence, and to avoid redundancy, descriptions of the same or similar cases are omitted below.

Thus, the bit sequence finally generated by the transmitting end may be: 1 (first class bit group) 11 (sub-bit sequence corresponding to resource block #1) 0 (sub-bit sequence corresponding to resource block #2) 1 (sub-bit sequence corresponding to resource block #3) 000 (sub-bit sequence corresponding to resource block # 4).

Here, since the first bit of the sub-bit sequence corresponding to the first type bit group and the resource block #1 is 1, the first bit of the sub-bit sequence corresponding to the first type bit group and the resource block #1 may multiplex one bit, that is, the bit sequence finally generated by the transmitting end may also be: 1101000.

optionally, the resource scheduling information further includes first indication information for indicating a bandwidth of the target frequency domain.

Specifically, the transmitting end may further transmit bandwidth indication information (i.e., an example of the first indication information) indicating a bandwidth of the resource to be allocated to the receiving end.

It should be understood that the above-listed manner of scheduling resources based on the first indication information is merely an exemplary illustration, and the present invention is not limited thereto, for example, the communication system may also use only frequency domain resources with a specified bandwidth, in which case the transmitting end and the receiving end can know the bandwidth of the frequency domain resources to be allocated in advance without the indication of the transmitting end.

Accordingly, for example, the receiving end may determine, according to bandwidth indication information (i.e., an example of the first indication information) that is carried in the scheduling information and used for indicating the bandwidth of the frequency domain resource to be allocated, that the resource to be allocated scheduled this time is 20MHz (i.e., only includes one first-type frequency domain resource segment), and when the receiving end resolves that the bit sequence carried in the scheduling information is 1101000, the receiving end may determine that "1" of the first bit is a first-type bit group, which indicates that the frequency domain resource to be allocated of 20MHz is not allocated to 9 (or 8, that is, an example of the preset number) receiving ends.

Thereafter, the size of each resource block to be allocated may be determined according to the bit sequence, for example, the sub-bit sequence "11" indicates that the first resource block (i.e., resource block #1) in the frequency domain resources to be allocated is a2 × 26 type resource block;

the sub-bit sequence "0" indicates that the second resource block (i.e., resource block #2) in the frequency domain resources to be allocated is a 1 × 26 type of resource block, and is allocated to a different receiving end from the resource block # 1;

the sub-bit sequence "1" indicates that the third resource block (i.e., resource block #3) in the frequency domain resources to be allocated is a 1 × 26 type of resource block, and is allocated to a different receiving end from the resource block # 2;

in addition, although the resource block located at the default position in the 20MHz resource to be allocated is not indicated by the bit sequence, the receiving end may determine that the resource block located at the default position is the fourth resource block in the resource to be allocated according to the size of each resource block to be allocated.

The fifth resource block (i.e., resource block #4) of the frequency domain resources to be allocated by the sub-bit sequence "000" is a4 × 26 type of resource block, and is allocated to a different receiving end from the resource block # 3.

Since the bandwidth of the frequency domain resource to be allocated is 20MHz bandwidth, the reading of the bit sequence is ended.

Therefore, the receiving end completes the analysis of all bit sequences of the resources to be allocated with the bandwidth of 20MHz, and can acquire the size and the position of each resource to be allocated into which the resources to be allocated are divided.

For another example, fig. 8 shows another example of allocation of frequency domain resources of 20MHz bandwidth, and as shown in fig. 8, the frequency domain resources (in order from left to right in fig. 9) are divided into 9 1 × 26 resource blocks, where the resource block located at the center of the 20MHz bandwidth (i.e., the resource block indicated by the dashed-line box in fig. 8) is the default resource block.

Since the 20MHz resource to be allocated (i.e., including one first-class frequency-domain resource segment) shown in fig. 8 is allocated to 9 (or 8, i.e., an example of a preset number) receiving ends, the corresponding first-class bit group is 0.

That is, the bit sequence finally generated by the transmitting end may be: 0

Accordingly, for example, the receiving end may determine, according to bandwidth indication information (i.e., an example of the first indication information) that is carried in the scheduling information and used for indicating the bandwidth of the frequency domain resource to be allocated, that the resource to be allocated scheduled this time is 20MHz (i.e., only includes one first-type frequency domain resource segment), and when the receiving end resolves that the bit sequence carried in the scheduling information is 0, the receiving end may determine that "0" of the first bit is a first-type bit group, which indicates that the frequency domain resource to be allocated of 20MHz is allocated to 9 (or 8, that is, an example of the preset number) receiving ends.

Therefore, the receiving end completes the analysis of all bit sequences of the resources to be allocated with the bandwidth of 20MHz, and can acquire the size and the position of each resource to be allocated into which the resources to be allocated are divided.

For another example, fig. 9 shows an example of a resource block division manner of a frequency domain resource to be allocated with a bandwidth of 40MHz, as shown in fig. 9, the frequency domain resource to be allocated is actually divided into 5 resource blocks to be allocated, that is, the resource blocks to be allocated are sequentially divided into 1 resource block of 4 × 26 type (i.e., resource block #1 '), 3 resource blocks of 1 × 26 type (i.e., resource block # 0', resource block #2 ', and resource block # 3') in the order from left to right in fig. 9, 1 resource block of 2 × 26 type (i.e., resource block #4 '), and 9 resource blocks of 1 × 26 type, where the resource block shown by a dotted line box in fig. 9 is a default resource block, for example, resource block # 0'.

Here, the bandwidth of the frequency domain resource to be allocated is 40MHz, and includes two 20MHz frequency domain resource segments (hereinafter, for convenience of understanding and distinction, referred to as frequency domain resource segment #1 and frequency domain resource segment #2), first, a generation process of a bit sequence corresponding to the frequency domain resource segment #1 is described.

As shown in fig. 9, the first resource block (i.e., resource block # 1') in the frequency domain resource segment #1 is a4 × 26 type resource block, and thus, its corresponding sub-bit sequence is 111;

the second resource block to be allocated in frequency domain resource segment #1 (i.e., resource block # 0') is the resource block of the default position, not indicated by the bit sequence.

The third resource block (i.e., resource block # 2') in the frequency domain resource segment #1 is a 1 × 26 type resource block, and is allocated to a different receiving end from the resource block #1, and thus, its corresponding sub-bit sequence is 0;

the fourth resource block (i.e., resource block #3 ') in the frequency domain resource segment #1 is a 1 × 26 type resource block, and is allocated to a different receiving end from the resource block # 2', and thus, its corresponding sub-bit sequence is 1;

the fifth resource block (i.e., resource block #4 ') in the frequency domain resource segment #1 is a2 × 26 type resource block, and is allocated to a different receiving end from the resource block # 3', and thus, its corresponding sub-bit sequence is 00.

Since the frequency domain resource segment #1 shown in fig. 9 is not allocated to 9 (or 8) receiving terminals, the corresponding first type bit group to be allocated is 1.

Furthermore, since the first bit of the first type bit group corresponding to the frequency domain resource segment #1 and the first bit of the sub-bit sequence corresponding to the resource block #1 'are both 1, the first bit of the first type bit group corresponding to the frequency domain resource segment #1 and the first bit of the sub-bit sequence corresponding to the resource block # 1' may be multiplexed by one bit.

That is, the bit sequence corresponding to the frequency domain resource segment #1 may be: 1110100

As shown in fig. 9, the frequency domain resource segment #2 is divided into 9 resource blocks of 1 × 26 type (in order from left to right in fig. 9), wherein the resource block located at the center of the frequency domain resource segment #2 (i.e., the resource block indicated by the dashed-line box in fig. 9) is the default resource block.

Since the 20MHz frequency domain resource segment #2 shown in fig. 9 is allocated to 9 (or 8, i.e., an example of the preset number) receiving terminals, the first type bit group corresponding to the frequency domain resource segment #2 is 0.

That is, the bit sequence corresponding to the frequency domain resource segment #2 may be: 0

Therefore, the bit sequence corresponding to the frequency domain resource to be allocated of 40MHz is: 11101000

Accordingly, for example, the receiving end may determine, according to bandwidth indication information (i.e., an example of the first indication information) that is carried in the scheduling information and used for indicating the bandwidth of the frequency domain resource to be allocated, that the resource to be allocated scheduled this time is 40MHz (i.e., includes two first-class frequency domain resource segments), and when the receiving end resolves that the bit sequence carried in the scheduling information is 11101000, the receiving end may determine that "1" of the first bit is a first-class bit group corresponding to the first 20MHz frequency domain resource segment (i.e., frequency domain resource segment #1), which indicates that the frequency domain resource segment #1 is not allocated to 9 (or 8, i.e., an example of the preset number) receiving ends.

Thereafter, the size of each resource block to be allocated may be determined according to the bit sequence corresponding to the frequency domain resource segment #1, for example, the sub-bit sequence "111" indicates that the first resource block (i.e., resource block # 1') in the frequency domain resource segment #1 is a4 × 26 type resource block;

in addition, although the resource block located at the default position in the frequency domain resource segment #1 of 20MHz is not indicated by the bit sequence, the receiving end may determine that the resource block located at the default position is the second resource block in the resources to be allocated according to the size of each resource block to be allocated.

The sub-bit sequence "0" indicates that the third resource block (i.e., resource block #2 ') in the frequency domain resources to be allocated is a 1 × 26 type of resource block, and is allocated to a different receiving end from the resource block # 1';

the sub-bit sequence "1" indicates that the fourth resource block (i.e., resource block #3 ') in the frequency domain resources to be allocated is a 1 × 26 type of resource block, and is allocated to a different receiving end from the resource block # 2';

the fifth resource block (i.e., resource block #4 ') of the frequency domain resources to be allocated of the sub-bit sequence "00" is a2 × 26 type of resource block, and is allocated to a different receiving end from the resource block # 3'.

Since the bandwidth of the frequency domain resource segment #1 is 20MHz, the reading of the bit sequence corresponding to the frequency domain resource segment #1 is completed.

Thereafter, the receiving end may parse the bit sequence corresponding to the frequency domain resource segment #2, and since "0" of the first bit in the bit sequence is the first type bit group corresponding to the frequency domain resource segment #2, it indicates that the 20MHz frequency domain resource segment #2 is allocated to 9 (or 8, i.e., an example of the preset number) receiving ends.

Therefore, the receiving end completes the analysis of all bit sequences of the resources to be allocated with the bandwidth of 40MHz, and can acquire the size and the position of each resource to be allocated into which the resources to be allocated are divided.

For another example, fig. 10 shows an example of a resource block division manner of a frequency domain resource to be allocated with a bandwidth of 40MHz, as shown in fig. 10, the frequency domain resource to be allocated is actually divided into 7 resource blocks to be allocated, that is, 1 resource block of 4 × 26 type (i.e., resource block #1 "), 5 resource blocks of 1 × 26 type (i.e., resource block # 0", resource block #2 ", resource block # 3", resource block #4 ", resource block # 5") and 1 resource block of 242 type (i.e., resource block #6 ") in sequence from left to right in fig. 10, wherein the resource block indicated by a dotted line box in fig. 10 is a default resource block, for example, resource block # 0".

Here, the bandwidth of the frequency domain resource to be allocated is 40MHz, and includes two 20MHz frequency domain resource segments (hereinafter, for convenience of understanding and distinction, referred to as frequency domain resource segment # a and frequency domain resource segment # B), first, a generation process of a bit sequence corresponding to the frequency domain resource segment # a is described.

As shown in fig. 10, the first resource block (i.e., resource block #1 ") in the frequency domain resource segment # a is a4 × 26 type of resource block, and thus, its corresponding sub-bit sequence is 111;

the second resource block to be allocated (i.e., resource block #0 ") in frequency domain resource segment # a is the resource block of the default position, not indicated by the bit sequence.

The third resource block (i.e., resource block #2 ") in the frequency domain resource segment # a is a 1 × 26 type resource block, and is allocated to a different receiving end from the resource block #1 ″, and thus, its corresponding sub-bit sequence is 0;

the fourth resource block (i.e., resource block #3 ") in the frequency domain resource segment # a is a 1 × 26 type resource block, and is allocated to a different receiving end than resource block # 2", and thus, its corresponding sub-bit sequence is 1;

the fifth resource block (i.e., resource block #4 ") in the frequency domain resource segment # a is a 1 × 26 type resource block, and is allocated to a different receiving end from resource block #3 ″, and thus, its corresponding sub-bit sequence is 0.

The sixth resource block (i.e., resource block #5 ") in the frequency domain resource segment # a is a 1 × 26 type resource block, and is allocated to a different receiving end from the resource block #4 ″, and thus, its corresponding sub-bit sequence is 1

Since the frequency domain resource segment # a shown in fig. 10 is not allocated to 9 (or 8) receiving terminals, the corresponding first type bit group to be allocated is 1.

Furthermore, since the first bit of the sub-bit sequence corresponding to resource block #1 "(i.e., the first resource block in the frequency domain resource segment # a) and the bit of the first type bit group corresponding to frequency domain resource segment # a are all 1, one bit may be multiplexed between the first bit of the sub-bit sequence corresponding to resource block # 1" and the bit of the first type bit group corresponding to frequency domain resource segment # a.

That is, the bit sequence corresponding to the frequency domain resource segment # a may be: 1110101

As shown in fig. 10, the frequency domain resource segment # B (in order from left to right in fig. 9) is divided into 1 resource block of 242 types (i.e., resource block #6 "), and thus, its corresponding sub-bit sequence is 1111".

Since the 20MHz frequency domain resource segment # B shown in fig. 10 is not allocated to 9 (or 8, i.e., an example of a preset number) receivers, the first type bit group corresponding to the frequency domain resource segment # B is 1.

Furthermore, since the first bit of the sub-bit sequence corresponding to resource block #6 "(i.e., the first resource block in the frequency domain resource segment # B) and the bit of the first type bit group corresponding to the frequency domain resource segment # B are all 1, one bit may be multiplexed between the first bit of the sub-bit sequence corresponding to resource block # 6" and the bit of the first type bit group corresponding to the frequency domain resource segment # B.

That is, the bit sequence corresponding to the frequency domain resource segment # B may be: 1111

Therefore, the bit sequence corresponding to the frequency domain resource to be allocated of 40MHz is: 11101001111

Accordingly, for example, the receiving end may determine, according to bandwidth indication information (i.e., an example of the first indication information) carried in the scheduling information, for indicating a bandwidth of the frequency domain resource to be allocated, that the resource to be allocated scheduled this time is 40MHz (i.e., includes two first-class frequency domain resource segments), and when the receiving end resolves that the bit sequence carried in the scheduling information is 11101001111, the receiving end may determine that "1" of the first bit is a first-class bit group corresponding to the first 20MHz frequency domain resource segment (i.e., frequency domain resource segment # a), which indicates that the frequency domain resource segment # a is not allocated to 9 (or 8, i.e., an example of the preset number) receiving ends.

Thereafter, the size of each resource block to be allocated may be determined according to the bit sequence corresponding to the frequency domain resource segment # a, for example, the sub-bit sequence "111" indicates that the first resource block (i.e., resource block #1 ") in the frequency domain resource segment # a is a4 × 26 type resource block;

in addition, although the resource block located at the default position in the frequency domain resource segment # a of 20MHz is not indicated by the bit sequence, the receiving end may determine that the resource block located at the default position is the second resource block in the resources to be allocated according to the size of each resource block to be allocated.

The sub-bit sequence "0" indicates that the third resource block (i.e., resource block #2 ") in the frequency domain resources to be allocated is a 1 × 26 type of resource block, and is allocated to a different receiving end from the resource block # 1";

the sub-bit sequence "1" indicates that the fourth resource block (i.e., resource block #3 ") in the frequency domain resources to be allocated is a 1 × 26 type of resource block, and is allocated to a different receiving end from the resource block # 2";

the sub-bit sequence "0" indicates that the fifth resource block (i.e., resource block #4 ") of the frequency domain resources to be allocated is a 1 × 26 type of resource block, and is allocated to a different receiving end from the resource block # 3".

The sub-bit sequence "1" indicates that the sixth resource block (i.e., resource block #5 ") of the frequency domain resources to be allocated is a 1 × 26 type of resource block, and is allocated to a different receiving end from the resource block # 4".

Since the bandwidth of the frequency domain resource segment # a is 20MHz, the reading of the bit sequence corresponding to the frequency domain resource segment # a is completed.

Thereafter, the receiving end may parse the bit sequence corresponding to the frequency domain resource segment # B, and since "1" of the first bit in the bit sequence is the first type bit group corresponding to the frequency domain resource segment # B, it indicates that the 20MHz frequency domain resource segment # B is not allocated to 9 (or 8, i.e., an example of the preset number) receiving ends.

The sub-bit sequence "111" indicates that the seventh resource block (i.e., resource block #6 ") of the frequency domain resources to be allocated is a 242-type resource block.

Since the bandwidth of the frequency domain resource segment # B is 20MHz, the reading of the bit sequence corresponding to the frequency domain resource segment # B is completed.

Thus, the receiving end completes the analysis of all bit sequences of the resource to be allocated of the 40MHz bandwidth as shown in fig. 10, and can know the size and position of each resource to be allocated into which the resource to be allocated is divided.

Second embodiment

Optionally, the bit sequence includes a second class of bit groups, where the second class of bit groups is used to indicate whether a second class of frequency domain resource segments is allocated to 1 receiving end, and a frequency domain width of the second class of frequency domain resource segments is a frequency domain width of a largest resource block position among resource block positions where the frequency domain resources to be allocated may be divided when the frequency domain resources to be allocated are allocated to multiple receiving ends.

Specifically, as described above, in the resource allocation method agreed in the next generation protocol, when the frequency domain resource to be allocated is allocated to a plurality of receiving terminals, the largest frequency domain resource segment (i.e., the second type of frequency domain resource segment) capable of allocating one receiving terminal may be allocated to 1 receiving terminal or a plurality of receiving terminals.

The second type of frequency domain resource segment may be a resource segment on one side of a symmetric center of the frequency domain resources to be allocated, that is, the size of the second type of frequency domain resource segment may be half of the bandwidth of the frequency domain resources to be allocated.

Therefore, a second-class bit group may be included in the bit sequence corresponding to the frequency domain resource to be allocated, where a second-class bit group may include at least one bit, and one second-class bit group is used to indicate whether the corresponding second-class frequency domain resource segment is allocated to a receiving end.

As an example and not by way of limitation, in this embodiment of the present invention, a second-class bit group may be formed by 2 bits, where the 2 bits are used to indicate whether a corresponding second-class frequency domain resource segment is allocated to 1 receiving end, and in this embodiment of the present invention, a transmitting end and a receiving end may determine, according to pre-negotiation or system specification, a mapping relationship of a case where the second-class bit group and the corresponding second-class frequency domain resource segment are allocated to 1 receiving end, for example:

00 may represent that the corresponding second type of frequency domain resource segment (e.g., when the bandwidth of the frequency domain resource to be allocated is 40MHz, the size of the second type of frequency domain resource segment is 242 types of resource blocks; further, for example, when the bandwidth of the frequency domain resource to be allocated is 80MHz, the size of the second type of frequency domain resource segment is 2 × 242 types of resource blocks; further, for example, when the bandwidth of the frequency domain resource to be allocated is 160MHz, the size of the second type of frequency domain resource segment is 996 types of resource blocks) is allocated to 1 receiving end;

01(10, or 11) may indicate that the corresponding second type of frequency domain resource segment is not allocated to 1 receiving end.

In addition, in the embodiment of the present invention, the second embodiment and the first embodiment may be used alone or in combination, and the present invention is not particularly limited, for example, when the second embodiment is used in combination with the first embodiment, the first bit group may include 2 bits, which is by way of example and is not limited.

01 may also indicate that the corresponding first type of frequency domain resource segment is not allocated to 9 (or 8) receiving ends.

In addition, in the embodiment of the present invention, the bit sequence may further include bits for indicating the size of each resource block to be allocated, for example, in addition to the first type of bit group, the bit sequence may further include multiple segments of sub-bit sequences, the multiple segments of sub-bit sequences correspond to multiple resource blocks to be allocated in a one-to-one manner, where each segment of sub-bit sequence is composed of one or more consecutive "1" or "0", where consecutive "1" or "0" indicates that the resource block to be allocated corresponding to the segment of sub-bit sequence is given to the same user, and when a bit in the multiple segments of sub-bit sequences changes from 1 to 0 or from 0 to 0, this indicates that the boundary of two resource blocks to be allocated here is present, that is, the resource to be allocated is changed from being allocated to one receiving end to being allocated to another receiving end.

In the embodiment of the present invention, the sub-bit sequences of each length and the resource blocks of the types may have the following mapping relationship:

1 (or 0) represents that the resource block to be allocated is a 1 × 26 type resource block;

11 (or 00) represents that the resource block to be allocated is a2 × 26 type resource block;

111 (or 000) denotes a resource block to be allocated as a4 × 26 type resource block.

The mapping relationship between the sub-bit sequences of each length and the resource blocks of the type listed above is only an exemplary illustration, and the present invention is not limited thereto, for example, when the bandwidth to be allocated with the frequency domain resource is greater than 20MHz (for example, 40MHz, 80MHz, 160MHz, etc.), the following mapping relationship may be included in addition to the mapping relationship between the sub-bit sequences of each length and the resource blocks of the type in the 20MHz described above:

1111 (or 0000) denotes a resource block to be allocated as a 242 type resource block.

For example, fig. 11 shows an example of a resource block division manner of a frequency domain resource to be allocated with a bandwidth of 80MHz, as shown in fig. 11, the frequency domain resource to be allocated is actually divided into 17 resource blocks to be allocated, that is, the frequency domain resource to be allocated is sequentially divided into 1 resource block of 4 × 26 type (i.e., resource block #1 "'), 15 resource blocks of 1 × 26 type (i.e., resource block # 0" ', resource block #2 "', resource block # 3" ', resource block #4 "', resource block # 5" ', … …, resource block #000 "', and 1 resource block of 2 × 242 type (i.e., resource block # 6" ') in an order from left to right in fig. 11, where resource block #0 "', resource block # 00" ', and resource block #000 "' are default resource blocks.

In multi-user transmission, the largest resource that may be allocated to one user among the frequency domain resources to be allocated with a bandwidth of 80MHz (i.e., the second type of frequency domain resource segment in 80 MHz) is 40MHz, and therefore, the frequency domain resources to be allocated with 80MHz include two second type of frequency domain resource segments in total (hereinafter, for convenience of understanding and distinction, referred to as frequency domain resource segment # α and frequency domain resource segment # β).

As shown in FIG. 11, since frequency domain resource segment # α is not allocated to 1 receiver, the second type bit set (denoted as second type bit set #1) corresponding to frequency domain resource segment # α is not 00 (e.g., may be 10, 11 or 01).

Frequency domain resource segment # α is 40MHz wide and includes two 20MHz first class frequency domain resource segments (denoted frequency domain resource segment # α)1And frequency domain resource segment # α2) Therefore, the frequency domain resource segment # α can be determined in the manner of embodiment one1The corresponding first type bit sequence group (denoted as bit group # α)1) And frequency domain resource segment # α2The corresponding first type bit sequence group (denoted as bit group # α)2)。

As shown in FIG. 11, since the frequency domain resource segment # α 1 is not allocated to 9 (or 8) receivers, the bit group # α1Is not 01 (e.g., may be 10 or 11).

As shown in fig. 11, the first resource block (i.e., resource block #1 "') in frequency domain resource segment # α 1 is a4 × 26 type resource block, and thus, its corresponding sub-bit sequence is 111;

frequency domain resource segment # α1The second resource block to be allocated (i.e., resource block # 0' ") in (b) is the resource block of the default position, not indicated by the bit sequence.

Frequency domain resource segment # α1The third resource block (i.e., resource block #2 '") in (1 × 26) is a 1 × 26 type resource block, and is allocated to a different receiving end from resource block # 1'", and therefore, its corresponding sub-bit sequence is 0;

frequency domain resource segment # α1The fourth resource block (i.e., resource block #3 '") in (1 × 26) is a 1 × 26 type resource block, and is allocated to a different receiving end from resource block # 2'", and thus, its corresponding sub-bit sequence is 1;

frequency domain resource segment # α1The fifth resource block (i.e., resource block #4 '") in (1 × 26) is a 1 × 26 type resource block, and is allocated to a different receiving end from resource block # 3'", and thus, its corresponding sub-bit sequence is 0;

frequency domain resource segment # α1The sixth resource block (i.e., resource block #5 '") in (b) is a 1 × 26 type resource block, and is allocated to a different receiving end from resource block # 4'", and therefore, its corresponding sub-bit sequence is 1.

Thus, 20MHz frequency domain resource segment # α is indicated1The sub-bit sequence of the actual divided resource block is 1110101.

And, since the frequency domain resource is segmented # α1Corresponding bit group # α1Is not 01 (e.g., may be 10 or 11), and resource block # 1' ″ (i.e., frequency domain resource segment # α)1First resource block) is 111, and thus, bit group # α is set as the sub-bit sequence1The sub-bit sequence corresponding to resource block #1 "may multiplex the first two bits.

That is, frequency domain resource segment # α of 20MHz is indicated1The corresponding bit sequence is 1110101.

As shown in fig. 11, since the first frequency-domain resource segment # 2' is allocated to 9 (or 8) receiving terminals, the bit group # α2Is 01.

Thus, the bit sequence corresponding to frequency domain resource segment # α can be determined to be 111010101.

As shown in FIG. 11, since the frequency domain resource segment # β is allocated to 1 receiver, the second class of bit set (denoted as bit set # β) corresponding to the frequency domain resource segment # β is 00.

Thus, the bit sequence corresponding to the frequency domain resource to be allocated of 80MHz shown in fig. 11 can be determined to be 11101010100.

Accordingly, for example, the receiving end may determine, according to bandwidth indication information (i.e., an example of the first indication information) carried in the scheduling information, for indicating a bandwidth of the frequency domain resource to be allocated, that the resource to be allocated scheduled this time is 80MHz, that is, includes two second-class frequency domain resource segments (i.e., frequency domain resource segments of 40 MHz), and when the receiving end resolves that the bit sequence carried in the scheduling information is 11101010100, the receiving end may determine that "11" of the first two bits is a second-class bit group (i.e., second-class bit group #1) corresponding to the first second-class frequency domain resource segment (i.e., frequency domain resource segment # α), which indicates that the frequency domain resource segment # α is not allocated to 1 receiving end.

And, the receiving end may determine that the width of the frequency domain resource segment # α is 40MHz, and includes two first-type frequency domain resource segments (i.e., 20MHz frequency domain resource segments), and when the receiving end parses the bit sequence carried in the scheduling information to be 11101010100, the receiving end may determine that "11" of the first two bits is the first-type frequency domain resource segment (i.e., frequency domain resource segment # α)1) Corresponding first type bit group (i.e., bit group # α)1) Thus, the frequency domain resource segment # α may be determined1Not to 9 (or 8) receivers.

Thereafter, segment # α can be segmented from the frequency domain resources1The corresponding bit sequence determines the size of each resource block to be allocated, e.g., sub-bit sequence "111" indicates frequency domain resource segment # α1Of (2) (i.e., resource block #1) "') resource blocks of the 4 × 26 type;

furthermore, despite the 20MHz frequency domain resource segment # α1The resource block at the default position is not indicated by the bit sequence, but the receiving end may determine that the resource block at the default position is the second resource block in the resource to be allocated according to the size of each resource block to be allocated.

The sub-bit sequence "0" indicates that the third resource block (i.e., resource block #2 '") in the frequency domain resources to be allocated is a 1 × 26 type resource block, and is allocated to a different receiving end from the resource block # 1'";

the sub-bit sequence "1" indicates that the fourth resource block (i.e., resource block #3 '") in the frequency domain resources to be allocated is a 1 × 26 type resource block, and is allocated to a different receiving end than the resource block # 2'";

the sub-bit sequence "0" indicates that the fifth resource block (i.e., resource block #4 '") of the frequency domain resources to be allocated is a 1 × 26 type of resource block, and is allocated to a different receiving end from the resource block # 3'".

The sub-bit sequence "1" indicates that the sixth resource block (i.e., resource block #5 '") in the frequency domain resources to be allocated is a 1 × 26 type of resource block, and is allocated to a different receiving end from the resource block # 4'".

Since frequency domain resource segment # α1Is 20MHz bandwidth, so frequency domain resource segment # α1The reading of the corresponding bit sequence is ended.

Thereafter, the receiving end may parse frequency-domain resource segment # α2Corresponding bit sequence, since the first two bits of the bit sequence have "01" as frequency domain resource segment # α2Corresponding first type bit group (i.e., bit group # α)2) The 20MHz frequency domain resource segment # α is shown2Is allocated to 9 (or 8, i.e., an example of a preset number) receiving terminals.

Since frequency domain resource segment # α2Is 20MHz bandwidth, so frequency domain resource segment # α2The reading of the corresponding bit sequence is ended.

Thus, the receiving end completes parsing of the entire bit sequence of the frequency domain resource segment # α for the 40MHz bandwidth.

The remaining bits are 00, the receiver may determine "00" as the second class of bit set (i.e., bit set # β) corresponding to the second class of frequency-domain resource segment (i.e., frequency-domain resource segment # β), indicating that frequency-domain resource segment # β is allocated to 1 receiver.

Thus, the receiving end completes parsing of the entire bit sequence of the frequency domain resource segment # β for the 40MHz bandwidth.

Therefore, the receiving end completes the analysis of all bit sequences of the frequency domain resources to be allocated of the 80MHz bandwidth, and can acquire the size and the position of each resource to be allocated into which the resource to be allocated is divided.

Optionally, the bit sequence includes a third class of bit groups, where the third class of bit groups is used to indicate whether a third class of frequency domain resource segments is allocated to 1 receiving end, and a frequency domain width of the third class of frequency domain resource segments is a frequency domain width of a second resource block position in resource block positions where the frequency domain resources to be allocated may be divided when the frequency domain resources to be allocated are allocated to multiple receiving ends.

Specifically, in the resource allocation method agreed in the next generation protocol as described above, when the frequency domain resource to be allocated is allocated to a plurality of receiving terminals, the second largest frequency domain resource segment (i.e., the third type of frequency domain resource segment) capable of allocating one receiving terminal may be allocated to 1 receiving terminal or a plurality of receiving terminals.

The third type of frequency domain resource segment may be a resource segment on one side of a symmetric center of the second type of frequency domain resource segment, that is, the size of the third type of frequency domain resource segment may be one fourth of the bandwidth of the frequency domain resource to be allocated.

Therefore, a third bit group may be included in the bit sequence corresponding to the frequency domain resource to be allocated, where a third bit group may include at least one bit, and a third bit group is used to indicate whether the corresponding third frequency domain resource segment is allocated to a receiving end.

In this case, the second-class bit group and the third-class bit group may be formed by 2 bits, where the 2 bits are used to indicate whether the corresponding second-class frequency domain resource segment or the corresponding third-class frequency domain resource segment is allocated to 1 receiving end, in this embodiment of the present invention, the sending end and the receiving end may determine, according to pre-negotiation or system specification, a mapping relationship in a case where the second-class bit group and the corresponding second-class frequency domain resource segment are allocated to 1 receiving end, and a mapping relationship in a case where the third-class bit group and the corresponding third-class frequency domain resource segment are allocated to 1 receiving end, for example:

00 may indicate that a corresponding second type of frequency domain resource segment (for example, when the bandwidth of the frequency domain resource to be allocated is 80MHz, the size of the second type of frequency domain resource segment is the size of a resource block of 2 × 242 type) is allocated to 1 receiving end;

01 may indicate that a corresponding third type of frequency domain resource segment (for example, when the bandwidth of the frequency domain resource to be allocated is 80MHz, the size of the resource block of the third type is 242 types) is allocated to 1 receiving end.

In addition, in the embodiment of the present invention, the bit sequence may further include bits for indicating the size of each resource block to be allocated, for example, in addition to the first type of bit group, the bit sequence may further include multiple segments of sub-bit sequences, the multiple segments of sub-bit sequences correspond to multiple resource blocks to be allocated in a one-to-one manner, where each segment of sub-bit sequence is composed of one or more consecutive "1" or "0", where consecutive "1" or "0" indicates that the resource block to be allocated corresponding to the segment of sub-bit sequence is given to the same user, and when a bit in the multiple segments of sub-bit sequences changes from 1 to 0 or from 0 to 0, this indicates that the boundary of two resource blocks to be allocated here is present, that is, the resource to be allocated is changed from being allocated to one receiving end to being allocated to another receiving end.

In the embodiment of the present invention, one bit, for example, "1" or "0", may refer to the size of the smallest resource block actually allocated to one receiving end in the communication system.

For example, the minimum resource block actually allocated to a receiving end may be the minimum resource block position (i.e., the position including 26 subcarriers, or 1 × 26 type resource blocks) that is agreed in the next generation protocol followed by the wireless local area network listed above and may be divided for the frequency domain resource to be allocated, which is only an exemplary illustration, and the present invention is not limited thereto, and the minimum resource block actually allocated to a receiving end may also be a position of any other size, for example, the minimum resource block actually allocated to a receiving end may include 2 × 26 subcarriers, or 2 × 26 type resource blocks.

In this case, one bit, for example, "1" or "0", may refer to the allocation of a resource block having a size of 2 × 26.

In the embodiment of the present invention, the sub-bit sequences of each length and the resource blocks of the types may have the following mapping relationship:

1 (or 0) represents that the resource block to be allocated is a2 × 26 type resource block;

11 (or 00) denotes that the resource block to be allocated is a4 × 26 type resource block.

For example, fig. 12 shows an example of a resource block division manner of a frequency domain resource to be allocated with a bandwidth of 80MHz, and as shown in fig. 12, the frequency domain resource to be allocated is actually divided into 7 resource blocks to be allocated, i.e., into 1 resource block of 242 types (i.e., resource block #1 ""), 2 resource blocks of 2 × 26 types (i.e., resource block #2 "" and resource block #3 ""), 1 resource block of 1 × 26 type (i.e., default resource block #0 ""), 1 resource block of 4 × 26 type (i.e., resource block #4 ""), 1 resource block of 1 × 26 type (i.e., default resource block #00 ""), and 1 resource block of 2 × 242 types (i.e., resource block #5 "") in order from left to right in fig. 12.

In multi-user transmission, the largest resource that may be allocated to one user among the frequency domain resources to be allocated with a bandwidth of 80MHz (i.e., the second type of frequency domain resource segment in 80 MHz) is 40MHz, and therefore, the frequency domain resources to be allocated with 80MHz include two second type of frequency domain resource segments in total (hereinafter, for convenience of understanding and distinction, referred to as frequency domain resource segment # X and frequency domain resource segment # Y).

As shown in fig. 12, since the frequency domain resource segment # X is not allocated to 1 receiving end, the second-type bit set (denoted as: second-type bit set #1) corresponding to the frequency domain resource segment # X is not 00.

Also, in multi-user transmission, the second largest resource (i.e., the third kind of frequency domain resource segment in 80 MHz) that may be allocated to one user among the frequency domain resources to be allocated with the bandwidth of 80MHz is 20MHz, and thus, the frequency domain resource segment # X of 40MHz includes 2 third kind of frequency domain resource segments (hereinafter, for convenience of understanding and distinction, it is referred to as frequency domain resource segment # X)1Sum frequency domain resource segment # X2)。

As shown in FIG. 12, frequency domain resource segment # X1Is allocated to 1 user, and thus frequency domain resource segment # X1The corresponding third group of bits is 01.

As shown in FIG. 12, frequency domain resource segment # X2Is not assigned to 1 user and is therefore determined. Frequency domain resource segmentation # X2The sub-bit sequence corresponding to each resource block.

As shown in FIG. 12, frequency domain resource segment # X2The first resource block (i.e., resource block #2 "") in (a) is a2 × 26 type resource block, and thus, its corresponding sub-bit sequence is 1;

frequency domain resource segmentation # X2The second resource block (i.e., resource block #3 "") in (a) is a2 × 26 type resource block and is allocated to a different receiving end from resource block #1 "", and thus, its corresponding sub-bit sequence is 0;

frequency domain resource segmentation # X2The third resource block to be allocated (i.e., resource block #0 "") is the resource block of the default position, not indicated by the bit sequence.

Frequency domain resource segmentation # X2The fourth resource block to be allocated (i.e., resource block #4 ') is a4 × 26 type resource block, and is allocated to a different receiving end from resource block # 3', so its corresponding sub-bit sequence is 11. The corresponding bit sequence is 1011

Thus, frequency domain resource segment # X may be determined2The corresponding bit sequence is 1011.

Further, the bit sequence corresponding to the frequency domain resource segment # X may be determined to be 011011.

The resource block (i.e., resource block #00 "") located at the middle position in the frequency domain resource to be allocated with the bandwidth of 80MHz is the resource block at the default position, and is not indicated by the bit sequence.

As shown in fig. 12, the frequency domain resource segment # Y is allocated to 1 user, so the third type bit group corresponding to the frequency domain resource segment # Y is 00;

further, the bit sequence corresponding to the frequency domain resource segment with the bandwidth of 80MHz shown in fig. 12 can be determined to be 01101100.

Accordingly, for example, the receiving end may determine, according to bandwidth indication information (i.e., an example of the first indication information) carried in the scheduling information, for indicating a bandwidth of the frequency domain resource to be allocated, that the resource to be allocated scheduled this time is 80MHz, that is, includes two second-class frequency domain resource segments (i.e., frequency domain resource segments of 40 MHz), and when the receiving end resolves that the bit sequence carried in the scheduling information is 01101100, the receiving end may determine that "01" of the first two bits is a second-class bit group corresponding to the first second-class frequency domain resource segment (i.e., frequency domain resource segment # X), which indicates that the frequency domain resource segment # X is not allocated to 1 receiving end.

And, the receiving end may determine that the width of the frequency domain resource segment # X is 40MHz, and includes two third-type frequency domain resource segments (i.e., 20MHz frequency domain resource segments), and when the receiving end resolves that the bit sequence carried in the scheduling information is 01101100, the receiving end may determine that "01" of the first two bits is the first third-type frequency domain resource segment (i.e., frequency domain resource segment # X)1) Corresponding third type bit group, thereby determining the frequency domain resource segment # X1Is allocated to 1 receiving end.

When the receiving end resolves that the bit sequence carried in the scheduling information is 01101100, it can be determined that "10" of the two bits located at the 3 rd and 4 th bits is the second third class frequency domain resource segment (i.e. frequency domain resource segment # X)2) Corresponding third type bit group, thereby determining the frequency domain resource segment # X2Not to 1 receiver.

Thereafter, # X may be segmented according to the frequency domain resources2The corresponding bit sequence (i.e., 1011) determines the size of each resource block to be allocated, e.g., sub-bit sequence "1" represents frequency domain resource segment # X2Is a2 × 26 type resource block (i.e., resource block #2 "");

sub-bit sequence "0" represents frequency domain resource segment # X2The second resource block (i.e., resource block #3 "") in (a) is a 1 × 26 type resource block, and is allocated to a different receiving end from resource block #2 "";

furthermore, despite the 20MHz frequency domain resource segment # X2The resource block at the default position is not indicated by the bit sequence, but the receiving end may determine that the resource block at the default position is the third resource block in the resources to be allocated according to the size of each resource block to be allocated.

Sub-bit sequence "11" represents frequency domain resource segment # X2The fourth resource block (i.e., resource block #4 ') in (a) is a4 × 26 type resource block, and is allocated to a different receiving end from the resource block # 3'.

Due to frequency domain resource segmentation # X2Is 20MHz bandwidth, so frequency domain resource segment # X2The reading of the corresponding bit sequence is ended.

In addition, although the resource block located at the middle position in the frequency domain resource to be allocated of 80MHz is not indicated by the bit sequence, the receiving end may determine the existence of the resource block located at the default position according to the size of each resource block to be allocated.

Thereby, the receiving end completes parsing of the entire bit sequence of the frequency domain resource segment # X of the 40MHz bandwidth.

The remaining bits are 00, and the receiving end may determine that "00" is the second type bit set corresponding to the second type frequency domain resource segment (i.e., frequency domain resource segment # Y), which indicates that the frequency domain resource segment # Y is allocated to 1 receiving end.

Thereby, the receiving end completes parsing of the entire bit sequence of the frequency domain resource segment # Y for the 40MHz bandwidth.

Therefore, the receiving end completes the analysis of all bit sequences of the frequency domain resources to be allocated of the 80MHz bandwidth, and can acquire the size and the position of each resource to be allocated into which the resource to be allocated is divided.

Optionally, the resource scheduling information further includes identifiers of a plurality of scheduled receiving ends, where the identifiers of the receiving ends are used to indicate that the resource blocks to be allocated, into which the frequency domain resources to be allocated are actually divided, are allocated to the plurality of receiving ends.

Optionally, the resource scheduling information includes:

the resource scheduling information further includes fourth indication information for indicating a scheduling order of the plurality of scheduled receiving ends, wherein the scheduling order of the first receiving end corresponds to a position of the resource block to be allocated, allocated to the first receiving end, in the frequency domain resource to be allocated.

For example, the sender may notify each receiver in the system of the following information through a bit sequence, or bit map (bitmap):

A. the present frequency domain resource (i.e., the frequency domain resource to be allocated) is composed of a number of subcarriers included in each resource block included in the frequency domain resource to be allocated, or a type of each resource block included in the frequency domain resource to be allocated.

B. The position of each resource block in the frequency domain resource to be allocated.

Also, the transmitting end may notify each receiving end in the system whether it is scheduled or not and a location in the scheduled user through user group information (i.e., an example of the fourth indication information), or a station identification list (STA ID list) including identifications of a plurality of receiving ends.

Accordingly, the receiving end can determine the resource block allocated thereto by the transmitting end based on the above information, and receive or transmit data according to the resource block.

That is, after generating the bit sequence, the sending end may send resource allocation indication information including the bit sequence to each receiving end device, so that the receiving end device can determine, based on the resource allocation indication information, the frequency domain resource allocated to the sending end, and perform data or signaling transmission through the frequency domain resource.

The resource allocation indication information mainly completes allocation of a frequency spectrum under the current bandwidth, and after receiving the resource allocation indication, the receiving end can know the current transmission resource allocation mode, or the size and the position of a resource block included in the frequency domain resource to be allocated, through the bit sequence.

Then, it can know whether it is scheduled and the scheduled user (the scheduled user) by reading the STA ID list part of the resource scheduling information. The receiving end combines the two contents (the resource allocation indication information and the STA ID list, i.e. an example of the resource scheduling information), and can receive or transmit data at the corresponding scheduled position.

For example, as shown in fig. 13, it is assumed that the frequency domain resource to be allocated includes resource block 1, resource block 2, resource block 3, and resource block 4 from left to right in sequence.

The four resource blocks are allocated to four receiving sides (hereinafter, for convenience of understanding and explanation, denoted as STA 1, STA2, STA3, and STA4), the number of STAs in the STA ID list is equal to the total number of available resource blocks allocated by the transmitting side (e.g., AP), and the STAs in the STA ID list are arranged in the order of STA 1, STA2, STA3, and STA 4.

And the receiving end analyzes the bit sequence and the STA ID list to obtain the resource distributed to the receiving end by the transmitting end.

That is, the order of STA 1 in the STA ID list is the first, and thus it can determine that the allocated resource is the first resource block in the frequency domain resources to be allocated, that is, resource block 1.

Similarly, the order of STA2 in the STA ID list is second, so it can determine that the allocated resource is the second resource block in the frequency domain resource to be allocated, that is, resource block 2; the sequence of the STA3 in the STA ID list is the third, so that it can determine that the allocated resource is the third resource block in the frequency domain resource to be allocated, that is, resource block 3; the order of the STA4 in the STA ID list is fourth, so it can determine that the allocated resource is the fourth resource block in the frequency domain resource to be allocated, that is, resource block 4.

It should be understood that the above-listed manner of performing resource scheduling through the resource indication information and the STA ID list based on the above-mentioned bit sequence is only an exemplary illustration, and the present invention is not limited thereto.

For example, in a scenario where the STA is fixed, the order of each STA may be preset, and therefore, the AP only needs to notify the STA of the size and the position of each resource block in the frequency domain resource to be allocated through the resource indication information, and therefore, the transmission of the STA ID list may be omitted.

In addition, it should be noted that, in the embodiment of the present invention, the user group information is composed of a site identification list and is sent separately, or may also be used as a part of the user private information, that is, each STA ID is placed in the corresponding user private information.

Optionally, the resource scheduling information further includes first indication information for indicating a bandwidth of the target frequency domain.

Specifically, after determining the bandwidth of the frequency domain resource to be allocated, the receiving end can determine the size of the maximum resource block included in the frequency domain resource to be allocated according to, for example, the resource block distribution conditions shown in fig. 4 to fig. 6, so as to determine the preset number of subcarriers corresponding to each mapping rule, and therefore, the transmitting end can also transmit bandwidth indication information (i.e., an example of the first indication information) for indicating the bandwidth of the frequency domain resource to be allocated to the receiving end.

It should be understood that the above-mentioned manner of scheduling resources based on the first indication information is merely an exemplary illustration, and the present invention is not limited thereto, for example, in the case that the communication system uses only frequency domain resources with a specified bandwidth, the preset number of subcarriers corresponding to each mapping rule may be preset as a default value in the transmitting end and the receiving end.

Optionally, the resource scheduling information further includes second indication information for indicating whether each resource block is used for multi-user input and output MU-MIMO.

Specifically, as described above, the receiving end can determine the size and position of each resource block included in the frequency domain resource to be allocated according to the resource allocation indication information, and therefore, the transmitting end can also notify the receiving end through the MIMO indication information (i.e., an example of the second indication information) whether each resource block is used for performing MU-MIMO.

For example, assuming that the minimum granularity of resource blocks allowing MU-MIMO transmission is 242, the first resource block (resource block of 2 × 242 type) shown in fig. 13 performs MU-MIMO transmission, and other resource blocks (i.e., shaded resource blocks) do not perform MU-MIMO transmission.

For example, the MU-MIMO indication may be represented by a four-bit indication, i.e., "1000", where the first bit "1" indicates that the first resource block is used for MU-MIMO transmission and the second bit "0" indicates that the second resource block is used for MU-MIMO transmission. The third bit "0" indicates that the third resource block is not used for MU-MIMO transmission. The fourth bit "0" indicates that the fourth resource block is not used for MU-MIMO transmission.

In this case, when the receiving end does not determine the size and position of each resource block based on the resource allocation indication information, it is possible to determine whether each resource block can be used for MU-MIMO transmission based on the MU-MIMO indication information.

According to the resource scheduling method provided by the embodiment of the invention, the receiving end can know whether each resource block is used for MU-MIMO transmission, so that the transmission efficiency and reliability can be improved.

Optionally, the resource scheduling information further includes third indication information for indicating whether each resource block is available.

Specifically, as described above, the receiving end can determine the size and the position of each resource block included in the frequency domain resource to be allocated according to the resource allocation indication information, and therefore, the transmitting end can also notify the receiving end of whether each resource block is available or not by indicating information (i.e., third indication information) indicating whether each resource block is available or not.

For example, assuming that the division of each resource block in the frequency domain resource to be allocated is as shown in fig. 13, the resource block of the shaded portion is not available due to interference and the like.

For example, four bits may respectively indicate whether 4 resource blocks are available, for example, "0" indicates that the resource block is not available, and "1" indicates the resource block, where each bit corresponds to each resource block one to one, for example, a first bit corresponds to a first resource block, a second bit corresponds to a second resource block, a third bit corresponds to a third resource block, and a fourth bit corresponds to a fourth resource block, and then, the indication information of the four bits is "1000".

Mode 2. it can also indicate which resource block is not available with an index number, since the frequency domain resource to be allocated is divided into 4 resource blocks, only 2 bits are needed to represent the index number, for example, "00" represents the first resource block, "01" represents the second resource block, "10" represents the third resource block, and "11" represents the fourth resource block. In this case, the transmitting end may transmit the index number "00" of the available resource block to the receiving end as the third indication information, or the transmitting end may transmit the index number "011011" of the unavailable resource block to the receiving end as the third indication information, which is not particularly limited in the present invention.

According to the resource scheduling method provided by the embodiment of the invention, the receiving end can know whether each resource block is available, so that the transmission efficiency and reliability can be improved.

Optionally, the method is applied to a wireless local area network system, and

the transmitting the bit sequence to the receiving end includes:

loading the bit sequence in a high-efficiency signaling field A or a high-efficiency signaling field B in a lead code, and sending the bit sequence to the receiving end; or

And carrying the bit sequence on a media access control layer and sending the bit sequence to the receiving end.

Specifically, the packet structure of a WLAN system (e.g., 802.11ax) is shown in fig. 15, wherein the preamble portion includes a Legacy preamble followed by a High Efficiency (HE) preamble. The Legacy preamble includes a short Training Field (L-STF), a Long Training Field (L-LTF), a signaling Field (L-SIG), and a repeated signaling Field (Rpageted L-SIG). The High-efficiency preamble comprises a High-efficiency signaling Field A (HE-SIGA), a High-efficiency signaling Field B (HE-SIGB), a High-efficiency short Training Field (HE-STF) and a High-efficiency Long Training Field (HE-LTF). Optionally, the High efficiency preamble comprises a High efficiency signaling Field C (HE-SIGC). Also, the packet structure of the WLAN system may further include a DATA field (DATA).

HE-SIGA and HE-SIGB are broadcast to all users to carry signaling information in 802.11ax packet structures, and HE-SIG-B includes Common information Parameters (Common Parameters), resource allocation indication (resource allocation), site identification list (STA ID list), and each scheduled user site information (STA Parameters), as shown in fig. 16. Alternatively, the site id may be placed in the corresponding user site information, as shown in fig. 17. The common information parameters include Guard Interval (GI) used for data transmission, OFMDA/MU-MIMO indication, HE-LTF number and mode, and may include parameters such as uplink/downlink indication, presence or absence of conventional HE-SIGB, and the like. The user station information includes parameters such as the number of spatial streams of the user, Modulation and Coding Scheme (MCS) adopted for data transmission, Coding type, whether to use time-space-time code (STBC) indication and whether to use beamforming (beamforming) indication.

Therefore, in the embodiment of the present invention, the resource scheduling information may be carried in the HE-SIGA (for example, the HE-SIG a may carry bandwidth information) or the HE-SIGB (for example, the HE-SIG B may carry resource allocation information including the bit sequence, user group information, and the like) and transmitted to the receiving end.

Alternatively, in the embodiment of the present invention, the resource scheduling information may be carried in the medium access control layer, for example, the resource scheduling information may be carried in a medium access control header (MAC HEADER) in the medium access control layer, or other segments of the MAC layer.

Optionally, the resource scheduling information further includes default resource block allocation information used for indicating an allocation condition of a default resource block located at the default position in the resource block to be allocated, where the allocation condition of the default resource block includes at least one of the following conditions: the default resource block and the adjacent resource block are allocated to different receiving ends, the default resource block and the left adjacent resource block are allocated to the same receiving end, or the default resource block and the right adjacent resource block are allocated to the same receiving end.

Specifically, in the implementation of the present invention, the resource blocks located at the default positions (for example, the 1 × 26 type resource blocks located at the middle position of 20MHz, or the 1 × 26 type resource blocks located at the middle position of 80 MHz) may be allocated to one receiving end alone, or may be allocated jointly by being bound to adjacent (left or right) resource blocks.

Therefore, in the embodiment of the present invention, information indicating the allocation of the resource block located at the default position (i.e., default resource block allocation information) may be further added to the scheduling information.

Fig. 17 is a schematic diagram illustrating a manner of carrying information of resource block allocation, where as shown in fig. 17, a 1-bit indication bit is added to each user signaling Part (Per STA Part) in the HE-SIG-B field as information of the allocation, and when the bit is "0", it indicates that the default resource block is allocated to a receiving end (e.g., STA # n in fig. 17) to which the resource block adjacent to the left side of the default resource block is allocated; when the bit is "1", it indicates that the default resource block is allocated to the receiving side (for example, STA # m in fig. 17) to which the resource block adjacent to the right side of the default resource block is allocated.

In addition, the information of the allocation can be further extended, for example, using 2 bits to indicate. "00" indicates that the default resource block is not allocated, and "01" indicates that the default resource block is allocated to the receiving side to which the resource block adjacent to the left side of the default resource block is allocated, and "10" indicates that the default resource block is allocated to the receiving side to which the resource block adjacent to the right side of the default resource block is allocated, and "11" indicates that the default resource block is not allocated.

According to the resource scheduling method provided by the embodiment of the invention, at least part of bits in the bit sequence are used for indicating whether the frequency domain resource segments with the specified frequency domain width in the frequency domain resources to be allocated are allocated to the preset number of receiving ends, so that the bit sequences with different lengths can be flexibly generated according to the distribution condition of the resource blocks to be allocated, into which the frequency domain resources to be allocated are actually divided, and the resource block positions into which the frequency domain resources to be allocated are possibly divided, thereby being capable of supporting and reducing the overhead of resource scheduling on transmission resources.

Fig. 18 is a schematic flow chart of a method 200 for resource scheduling according to another embodiment of the present invention, which is described from the perspective of a receiving end, the method 200 is applied to a wireless local area network, the wireless local area network follows a next generation protocol in which resource block positions that may be divided for frequency domain resources to be allocated are agreed, as shown in fig. 18, the method 200 includes:

Alternatively, when the frequency domain width of the minimum resource block position is to include 26 consecutive subcarriers, the preset number is 8 or 9.

Optionally, the bit sequence includes a second class of bit groups, where the second class of bit groups is used to indicate whether a second class of frequency domain resource segments is allocated to 1 receiving end, and a frequency domain width of the second class of frequency domain resource segments is a frequency domain width of a largest resource block position among resource block positions where the frequency domain resources to be allocated may be divided when the frequency domain resources to be allocated are allocated to multiple receiving ends.
