基于多用户的BAR传输方法、资源调度方法、装置及系统Multi-user-based BAR transmission method, resource scheduling method, device and system

技术领域technical field

本发明实施例涉及通信技术领域，尤其涉及一种基于多用户的BAR传输方法、资源调度方法、装置及系统。Embodiments of the present invention relate to the field of communications technologies, and in particular, to a multi-user-based BAR transmission method, resource scheduling method, device, and system.

背景技术Background technique

单个基本服务集包括一个接入点(Access Point，简称AP)和多个站点STA，该AP和多个STA之前需要传输数据，即AP向多个STA发送下行数据，多个STA向AP发送上行数据。A single basic service set includes an Access Point (AP) and multiple STAs. The AP and multiple STAs need to transmit data before, that is, the AP sends downlink data to multiple STAs, and multiple STAs send uplink data to the AP. data.

在802.11ac及无线保真(Wireless Fidelity，简称WiFi)标准中，多个STA向AP发送上行数据时，每个STA在上行数据中媒体访问控制(Media Access Control，简称MAC)头的服务质量(Quality of Service，简称QoS)控制字段中设定AP对该上行数据的确认策略，该确认策略占用QoS控制字段两个比特，包括4种确认策略，具体的，“00”表示正常确认ACK或隐式块确认(Block Acknowledgement，简称BA)，“01”表示非显示ACK或节能轮询(Power-Save Multi-Poll，简称PSMP)下的调度ACK，“10”表示AP不需要对该上行数据进行确认，“11”表示AP向STA发送确认信息具体为块确认BA之前需要STA向AP发送块确认请求(BlockAcknowledgement Request，简称BAR)。In 802.11ac and Wireless Fidelity (Wireless Fidelity, WiFi for short) standards, when multiple STAs send uplink data to an AP, each STA in the uplink data Media Access Control (Media Access Control, referred to as MAC) header quality of service ( The acknowledgment strategy for the uplink data of the AP is set in the Quality of Service (QoS) control field. The acknowledgment strategy occupies two bits in the QoS control field, including 4 kinds of acknowledgment strategies. Specifically, "00" indicates normal ACK or hidden Block Acknowledgement (BA), "01" indicates non-display ACK or scheduling ACK under Power-Save Multi-Poll (PSMP), and "10" indicates that the AP does not need to perform the uplink data processing. Confirmation, "11" indicates that the AP sends the confirmation information to the STA, specifically, the STA needs to send a Block Acknowledgement Request (BAR for short) to the AP before the block acknowledgment BA.

当确认策略为“11”，多个STA向AP发送上行数据后，多个STA逐个向AP发送BAR，AP依据每个STA发给它的BAR向该STA发送BA，即通过多个STA逐个向AP发送BAR触发AP对上行数据进行块确认，降低了单个基本服务集的系统吞吐量，导致单个基本服务集的系统效率低。When the confirmation policy is "11", after multiple STAs send uplink data to the AP, multiple STAs send BARs to the AP one by one, and the AP sends BAs to the STA according to the BARs sent to it by each STA. The AP sends a BAR to trigger the AP to perform block acknowledgment on uplink data, which reduces the system throughput of a single basic service set, resulting in low system efficiency of a single basic service set.

以及WLAN(Wireless Local Area Networks，无线局域网)下一代协议引进的多用户同时通信技术，如OFDMA(Orthogonal Frequency Division Multiplex Access，正交频分多址接入)技术，AP需对待分配的频率资源进行划分，把划分成的资源块分配对应的每个站点。因此，WLAN下一代协议需要一种有效，对内存储存要求低的资源调度指示方法，指示站点被分配到哪个资源块进行传输。目前一种直接资源调度的方案，是采取罗列所有可能被分配的资源块，即采用一个大表索引对应可能的被分配的资源块，对内存储存要求高，且查表速度慢。因此，希望提供一种技术，能够支持减小内存储存要求，能够迅速查表的资源调度方法和装置。And the multi-user simultaneous communication technology introduced by the next generation protocol of WLAN (Wireless Local Area Networks, wireless local area network), such as OFDMA (Orthogonal Frequency Division Multiplex Access, Orthogonal Frequency Division Multiplex Access) technology, the AP needs to perform frequency resources to be allocated. Divide, allocate the divided resource blocks to each corresponding site. Therefore, the WLAN next-generation protocol needs an effective resource scheduling instruction method with low memory storage requirements, indicating which resource block the station is allocated to for transmission. A current solution for direct resource scheduling is to list all possible resource blocks that may be allocated, that is, to use a large table index to correspond to the possible allocated resource blocks, which requires high memory storage and slows table lookup. Therefore, it is desirable to provide a technology that can support a resource scheduling method and device that can reduce memory storage requirements and can quickly look up tables.

实施例1Example 1

图1为本发明实施例提供的基于多用户的BAR传输方法流程图。由于现有技术中多个STA向AP发送上行数据，且上行数据中的确认策略为“11”时，需要多个STA逐个向AP发送BAR，AP依据每个STA发给它的BAR向该STA发送BA，即通过多个STA逐个向AP发送BAR触发AP对上行数据进行块确认，降低了单个基本服务集的系统吞吐量，导致单个基本服务集的系统效率低，本发明实施例针对该现有技术中的问题提供了基于多用户的BAR传输方法，该方法具体步骤如下：FIG. 1 is a flowchart of a multi-user-based BAR transmission method provided by an embodiment of the present invention. Because in the prior art, multiple STAs send uplink data to the AP, and when the acknowledgment policy in the uplink data is "11", multiple STAs need to send BARs to the AP one by one, and the AP sends the BAR to the STA according to the BAR sent to it by each STA. Sending BA, that is, triggering the AP to perform block acknowledgment on the uplink data by sending BARs to the AP one by one through multiple STAs reduces the system throughput of a single basic service set, resulting in low system efficiency of a single basic service set. The problem in the prior art provides a multi-user-based BAR transmission method, and the specific steps of the method are as follows:

步骤S101、多个站点STA同时分别向接入点AP发送上行数据；Step S101, multiple station STAs respectively send uplink data to the access point AP at the same time;

本发明实施例以单个基本服务集为研究对象，该单个基本服务集包括一个接入点AP和多个站点STA，该AP为多个站点STA中的每一个STA设定一个唯一标识信息AID。多个站点STA同时分别向接入点AP发送上行数据，这里同时的传输方式可以为上行正交频分多址接入(Orthogonal Frequency Division Multiplex Access，简称OFDMA)，也可以为上行多用户多输入多输出(Multiple Users-Multiple Input Multiple Output,简称MU-MIMO)，每个STA在上行数据中媒体访问控制(Media Access Control，简称MAC)头的服务质量(Quality of Service，简称QoS)控制字段中设定AP对该上行数据的确认策略，该确认策略占用QoS控制字段两个比特，包括4种确认策略，具体的，“00”表示正常确认ACK或隐式块确认(Block Acknowledgement，简称BA)，“01”表示非显示ACK或节能轮询(Power-SaveMulti-Poll，简称PSMP)下的调度ACK，“10”表示AP不需要对该上行数据进行确认，“11”表示AP接收到数据后，除了记录接收状态不做任何立即响应。该接收端会期待后面接收一个BA请求帧(BA request，简称BAR)或一个确认策略为“00”的A-MPDU数据，然后再响应BA。若多个STA发送的上行数据的确认策略都设置为“11”时，AP向多个STA发送块确认BA之前需要多个STA逐个向AP发送块确认请求(Block Acknowledgement Request，简称BAR)，以触发AP依据每个STA发给它的BAR向该STA发送BA，从而实现AP对上行数据的确认。The embodiment of the present invention takes a single basic service set as a research object, the single basic service set includes an access point AP and multiple station STAs, and the AP sets a unique identification information AID for each STA in the multiple station STAs. Multiple station STAs send uplink data to the access point AP at the same time, and the simultaneous transmission mode here can be uplink orthogonal frequency division multiple access (Orthogonal Frequency Division Multiplex Access, OFDMA for short), or uplink multi-user multiple input Multiple Output (Multiple Users-Multiple Input Multiple Output, referred to as MU-MIMO), each STA in the Media Access Control (Media Access Control, referred to as MAC) header in the quality of service (Quality of Service, referred to as QoS) control field in the data header Set the AP's acknowledgment strategy for the uplink data. The acknowledgment strategy occupies two bits in the QoS control field, including 4 kinds of acknowledgment strategies. Specifically, "00" means normal acknowledgment ACK or implicit block acknowledgment (BA for short) , "01" indicates non-display ACK or scheduling ACK under Power-Save Multi-Poll (PSMP), "10" indicates that the AP does not need to confirm the uplink data, "11" indicates that the AP receives the data , do not respond immediately except to log the receive status. The receiver will expect to receive a BA request frame (BA request, BAR for short) or A-MPDU data with an acknowledgment policy of "00" later, and then respond to the BA. If the acknowledgment policies of the uplink data sent by multiple STAs are all set to "11", before the AP sends a block acknowledgment BA to multiple STAs, multiple STAs need to send a Block Acknowledgement Request (BAR for short) to the AP one by one. The AP is triggered to send the BA to the STA according to the BAR sent to it by each STA, so as to realize the confirmation of the uplink data by the AP.

在本发明实施例中每个STA在上行数据设定的确认策略可以不同，对于确认策略为“00”或“01”的上行数据，AP立即响应确认帧；对于确认策略为“10”的上行数据，AP不需要对该上行数据进行确认；对于确认策略为“11”的上行数据，AP向STA发送确认信息具体为块确认BA之前需要STA向AP发送块确认请求。In this embodiment of the present invention, each STA may have different acknowledgment strategies set in uplink data. For uplink data whose acknowledgment strategy is "00" or "01", the AP immediately responds to an acknowledgment frame; for uplink data whose acknowledgment strategy is "10" data, the AP does not need to confirm the uplink data; for the uplink data whose confirmation policy is "11", the AP sends the confirmation information to the STA. Specifically, the STA needs to send a block confirmation request to the AP before the block confirmation BA.

步骤S102、所述多个STA接收所述AP广播的多用户块确认请求轮询帧，所述多用户块确认请求轮询帧包括所述多个STA中每个STA的标识信息；Step S102, the multiple STAs receive a multi-user block acknowledgment request polling frame broadcast by the AP, where the multi-user block acknowledgment request polling frame includes identification information of each STA in the multiple STAs;

The identification information of each STA is used to trigger the multiple STAs to send a block acknowledgment request to the AP at the same time.

步骤S103、所述多个STA依据所述多用户块确认请求轮询帧同时向所述AP发送块确认请求，以触发所述AP对接收到的所述上行数据进行确认；Step S103, the multiple STAs simultaneously send a block acknowledgment request to the AP according to the multi-user block acknowledgment request polling frame, so as to trigger the AP to confirm the received uplink data;

所述多个STA接收到所述AP广播的多用户块确认请求轮询帧后，同时向所述AP发送块确认请求BAR，优选的，所述多个STA可以以MU的形式发送BAR，一种是以上行MU-MIMO的形式发送BAR，另一种是以上行OFDMA的形式发送BAR。After receiving the multi-user block acknowledgment request polling frame broadcast by the AP, the multiple STAs simultaneously send a block acknowledgment request BAR to the AP. Preferably, the multiple STAs may send the BAR in the form of MU, one One is to send the BAR in the form of uplink MU-MIMO, and the other is to send the BAR in the form of uplink OFDMA.

步骤S104、所述多个STA接收所述AP依据所述块确认请求发送的块确认。Step S104: The multiple STAs receive the block acknowledgment sent by the AP according to the block acknowledgment request.

所述确认请求BAR用于触发所述AP确认接收到的所述上行数据，具体为触发所述AP向所述多个STA发送块确认BA。AP在收到上行MU的BAR后向所述多个STA发送OFDMA BA或多站点块确认(Multi-STA Block Acknowledgement，简称M-BA)，以对上次收到的上行数据进行确认。The confirmation request BAR is used to trigger the AP to confirm the received uplink data, specifically triggering the AP to send a block confirmation BA to the multiple STAs. After receiving the BAR of the uplink MU, the AP sends OFDMA BA or Multi-STA Block Acknowledgement (M-BA for short) to the multiple STAs to confirm the uplink data received last time.

本发明实施例通过AP向多个STA广播多用户块确认请求轮询帧，触发多个STA同时向AP发送块确认请求，AP依据该块确认请求同时向多个STA发送块确认，以便对多个STA同时分别发送的上行数据进行确认，相比于多个STA逐个向AP发送BAR，AP依据每个STA发给它的BAR向该STA发送BA，提高了单个基本服务集的系统吞吐量，从而提高了单个基本服务集的系统效率。In this embodiment of the present invention, an AP broadcasts a multi-user block ack request polling frame to multiple STAs, triggering multiple STAs to send a block ack request to the AP at the same time, and the AP sends a block acknowledgment to multiple STAs simultaneously according to the block ack request, so that multiple Compared with multiple STAs sending BARs to the AP one by one, the AP sends BAs to the STA according to the BAR sent to it by each STA, which improves the system throughput of a single basic service set. This improves the system efficiency of a single basic service set.

Because in the prior art, multiple STAs send uplink data to the AP, and when the acknowledgment policy in the uplink data is "11", multiple STAs need to send BARs to the AP one by one, and the AP sends the BAR to the STA according to the BAR sent to it by each STA. Sending BA, that is, triggering the AP to perform block acknowledgment on the uplink data by sending BARs to the AP one by one through multiple STAs reduces the system throughput of a single basic service set, resulting in low system efficiency of a single basic service set.

所述多个站点STA中的任意一个STA向所述AP发送块确认请求，该块确认请求用于触发所述AP对所述多个站点STA同时分别发送的上行数据进行确认，如图8所示是该块确认请求的帧格式结构示意图，利用块确认请求帧中的保留字段(Reserved)1位或多位指示该BAR是触发AP发送对多个站点数据的确认，而不是对一个站点数据的确认。Any STA in the multiple station STAs sends a block acknowledgment request to the AP, and the block acknowledgment request is used to trigger the AP to confirm the uplink data sent by the multiple station STAs at the same time, as shown in FIG. 8 . This is a schematic diagram of the frame format structure of the block acknowledgment request. The reserved field (Reserved) in the block acknowledgment request frame is 1 or more bits to indicate that the BAR triggers the AP to send acknowledgments for multiple site data, not for one site data. 's confirmation.

另外，还可以通过块确认请求帧中多TID指示(Multi-TID)、压缩位图指示(Compressed Bitmap)和组播重传字段(GCR)三个比特的组合指示该BAR是触发AP发送对多个站点数据的确认，而不是对一个站点数据的确认。In addition, a combination of three bits in the block acknowledgment request frame, the Multi-TID indication (Multi-TID), the Compressed Bitmap indication (Compressed Bitmap), and the Multicast Retransmission (GCR) field can also be used to indicate that the BAR is triggering the AP to send a multi-to-multiple transmission. Confirmation of data for one site, not for one site.

步骤S703、所述多个站点STA接收所述AP依据所述块确认请求发送的块确认。Step S703: The multiple station STAs receive the block acknowledgment sent by the AP according to the block acknowledgment request.

AP接收到该块确认请求后向所述多个STA发送OFDMA BA或M-BA，以对上次收到的上行数据进行确认。After receiving the block acknowledgment request, the AP sends OFDMA BA or M-BA to the multiple STAs to confirm the last received uplink data.

实施例4Example 4

图10为本发明另一实施例提供的基于多用户的BAR传输方法流程图。由于现有技术中多个STA向AP发送上行数据，且上行数据中的确认策略为“11”时，需要多个STA逐个向AP发送BAR，AP依据每个STA发给它的BAR向该STA发送BA，即通过多个STA逐个向AP发送BAR触发AP对上行数据进行块确认，降低了单个基本服务集的系统吞吐量，导致单个基本服务集的系统效率低，本发明实施例针对该现有技术中的问题提供了基于多用户的BAR传输方法，该方法具体步骤如下：FIG. 10 is a flowchart of a multi-user-based BAR transmission method provided by another embodiment of the present invention. Because in the prior art, multiple STAs send uplink data to the AP, and when the acknowledgment policy in the uplink data is "11", multiple STAs need to send BARs to the AP one by one, and the AP sends the BAR to the STA according to the BAR sent to it by each STA. Sending BA, that is, triggering the AP to perform block acknowledgment on the uplink data by sending BARs to the AP one by one through multiple STAs reduces the system throughput of a single basic service set, resulting in low system efficiency of a single basic service set. The problem in the prior art provides a multi-user-based BAR transmission method, and the specific steps of the method are as follows:

步骤S1001、接入点AP接收多个站点STA同时分别发送的上行数据；Step S1001, the access point AP receives uplink data sent by multiple station STAs simultaneously;

步骤S1002、所述AP接收所述多个站点STA中的任意一个STA发送的块确认请求，所述块确认请求用于触发所述AP对所述多个站点STA同时分别发送的上行数据进行确认；Step S1002, the AP receives a block acknowledgment request sent by any one of the multiple station STAs, where the block acknowledgment request is used to trigger the AP to confirm the uplink data sent by the multiple station STAs at the same time. ;

另外，还可以通过块确认请求帧中Multi-TID,Compressed Bitmap和GCR三个比特的组合指示该BAR是触发AP发送对多个站点数据的确认，而不是对一个站点数据的确认。In addition, the combination of Multi-TID, Compressed Bitmap and GCR in the block ack request frame can also indicate that the BAR triggers the AP to send acknowledgments for data of multiple sites, rather than acknowledging data for one site.

步骤S1003、所述AP依据所述块确认请求向所述多个站点STA发送块确认。Step S1003, the AP sends a block acknowledgment to the multiple station STAs according to the block acknowledgment request.

在本发明实施例的基础上，所述接入点AP接收多个站点STA同时分别发送的上行数据之前，还包括：所述AP向所述多个STA广播用于触发所述多个STA同时分别向所述AP发送所述上行数据的触发帧。On the basis of the embodiment of the present invention, before the access point AP receives the uplink data sent by the multiple station STAs at the same time, the method further includes: the AP broadcasts to the multiple STAs to trigger the multiple STAs to simultaneously transmit the uplink data. Send the trigger frame of the uplink data to the AP respectively.

如图9所示，AP向STAs(代表多个站点STA)广播触发帧Trigger，该触发帧Trigger用于触发所述多个STA同时分别向所述AP发送上行数据Data。所述多个站点STA中的任意一个STA向所述AP发送块确认请求，该块确认请求用于触发所述AP对所述多个站点STA同时分别发送的上行数据进行确认，AP接收到该块确认请求后向所述多个STA发送OFDMA BA或M-BA，以对上次收到的上行数据进行确认。As shown in FIG. 9 , the AP broadcasts a trigger frame Trigger to STAs (representing multiple station STAs), and the trigger frame Trigger is used to trigger the multiple STAs to send uplink data Data to the AP simultaneously. Any STA in the multiple station STAs sends a block acknowledgment request to the AP, where the block acknowledgment request is used to trigger the AP to confirm the uplink data respectively sent by the multiple station STAs at the same time, and the AP receives the block acknowledgment request. After the block acknowledgment request, an OFDMA BA or M-BA is sent to the multiple STAs to confirm the last received uplink data.

本发明实施例通过多个站点STA中的任意一个STA向AP发送块确认请求，该块确认请求用于触发AP确认多个站点STA同时分别发送的上行数据，相比于多个STA逐个向AP发送BAR，AP依据每个STA发给它的BAR向该STA发送BA，提高了单个基本服务集的系统吞吐量，从而提高了单个基本服务集的系统效率。In this embodiment of the present invention, any one of the STAs on multiple sites sends a block acknowledgment request to the AP, where the block acknowledgment request is used to trigger the AP to confirm the uplink data sent by the STAs at the multiple sites at the same time. When sending a BAR, the AP sends a BA to the STA according to the BAR sent to it by each STA, which improves the system throughput of a single basic service set, thereby improving the system efficiency of a single basic service set.

图11为本发明实施例提供的基于多用户的BAR传输方法适用的下行OFDMA数据传输示意图。接入点AP向多个STA发送下行数据Data,下行数据Data中的确认策略为“11”，即STA向AP发送确认信息具体为块确认BA之前需要AP向STA发送块确认请求BAR，如图11所示，AP通过下行OFDMA的形式发送BAR帧触发相应站点回复BA帧，该下行OFDMA BAR帧不需要携带资源分配指示信息(该资源分配指示信息用来指示多个站点分别在哪个子信道上回复BA帧)，也不需要指示站点采用哪种MCS，GI，编码类型参数。本发明实施例中，站点回复的BA中的参数采用站点接收到的BAR的参数，例如，站点1在子信道2收到AP发送的BAR，该BAR采用MCS 2，则站点1同样采用MCS 2并在子信道2向AP回复BA。FIG. 11 is a schematic diagram of downlink OFDMA data transmission to which the multi-user-based BAR transmission method provided by the embodiment of the present invention is applicable. The access point AP sends downlink data Data to multiple STAs, and the acknowledgment policy in the downlink data Data is "11", that is, the STA sends the acknowledgment information to the AP. Specifically, the AP needs to send the block acknowledgment request BAR to the STA before sending the acknowledgment information to the AP, as shown in the figure. As shown in 11, the AP sends a BAR frame in the form of downlink OFDMA to trigger the corresponding station to reply to the BA frame, and the downlink OFDMA BAR frame does not need to carry resource allocation indication information (the resource allocation indication information is used to indicate which sub-channel multiple stations are on respectively. Reply BA frame), and it is not necessary to indicate which MCS, GI, and encoding type parameters the station adopts. In this embodiment of the present invention, the parameters in the BA returned by the station adopt the parameters of the BAR received by the station. For example, ifstation 1 receives the BAR sent by the AP onsubchannel 2, and the BAR adoptsMCS 2, thenstation 1 also adoptsMCS 2. And reply BA to AP onsub-channel 2.

图12为现有技术中的下行OFDMA数据传输示意图。接入点AP向多个STA发送下行数据Data,下行数据Data中的确认策略为“11”，如图12所示，AP通过发送广播多站点块请求(Multi-STA BAR，简称MU-BAR)帧，触发多个站点同时通过OFDMA发送BA帧确认接收到的下行数据。FIG. 12 is a schematic diagram of downlink OFDMA data transmission in the prior art. The access point AP sends downlink data Data to multiple STAs, and the acknowledgment policy in the downlink data Data is "11". As shown in Figure 12, the AP sends a Broadcast Multi-Site Block Request (Multi-STA BAR, MU-BAR for short) frame, triggering multiple stations to simultaneously send BA frames through OFDMA to confirm the received downlink data.

本发明实施例通过AP以下行OFDMA的形式发送BAR帧触发多个站点回复BA帧，且站点回复的BA中的参数采用站点接收到的BAR的参数，相比于现有技术中AP发送一个MU-BAR广播帧来触发多个站点通过OFDMA形式回复BA帧，不需要新定义一个控制帧-MU-BAR广播帧，增加了AP触发多个站点回复BA帧的灵活性。In this embodiment of the present invention, the AP sends a BAR frame in the form of downlink OFDMA to trigger multiple stations to reply to the BA frame, and the parameters in the BA returned by the station adopt the parameters of the BAR received by the station. Compared with the prior art, the AP sends one MU -BAR broadcast frame to trigger multiple stations to reply to BA frame through OFDMA, no need to define a new control frame -MU-BAR broadcast frame, which increases the flexibility of the AP to trigger multiple stations to reply to BA frame.

本发明上述实施例1到实施4提到的通信过程图2，图6，图9都设计到触发帧的发送，另外图3为触发帧的结构图。下面实施例基于图3中的触发帧结构图，提出一种位于站点信息的中资源调度信息指示方法。但本发明提出的资源调度信息指示方法并不限于位于触发帧内。The communication process mentioned in the above-mentionedEmbodiments 1 to 4 of the present invention is all designed to send a trigger frame in FIG. 2 , FIG. 6 , and FIG. 9 , and FIG. 3 is a structural diagram of the trigger frame. The following embodiment proposes a method for indicating resource scheduling information located in the site information based on the trigger frame structure diagram in FIG. 3 . However, the resource scheduling information indication method proposed by the present invention is not limited to be located in the trigger frame.

WLAN下一代协议中已引进OFDMA(Orthogonal Frequency Division MultiplexAccess，正交频分多址接入)技术，于是WLAN系统将带宽频谱资源划分成若干个正交的的子信道，每个子信道对应一个资源块。在WLAN系统中，资源块大小的划分以26个子载波为一个资源单元。如图13所示，以20兆赫兹的带宽为例，WLAN系统中在数据符号部分的离散傅里叶变换/离散傅里叶逆变换点数为256，也就是存在256个子载波，其中子载波-1、0、1为DC(Direct current，直流分量)，左边带子载波-122到子载波-2以及右边带子载波2到子载波122用于承载数据信息，也就是有242个子载波用于承载数据信息。子载波-128到子载波-123以及子载波123到子载波128为保护带。因此，通常用于承载数据信息的242个子载波被分成9个子资源块，每个子资源块包括26个子载波，剩余8个未使用的子载波。并且，位于带宽中心的子资源块跨DC(即，包括子载波-1、0、1)，本发明实施例的方法主要涉及对用于承载数据信息的242个子载波的分配。The OFDMA (Orthogonal Frequency Division Multiplex Access, Orthogonal Frequency Division Multiple Access) technology has been introduced in the WLAN next-generation protocol, so the WLAN system divides the bandwidth spectrum resources into several orthogonal sub-channels, and each sub-channel corresponds to a resource block . In the WLAN system, the size of the resource block is divided by 26 subcarriers as a resource unit. As shown in Figure 13, taking the bandwidth of 20 MHz as an example, the number of discrete Fourier transform/inverse discrete Fourier transform points in the data symbol part in the WLAN system is 256, that is, there are 256 subcarriers, of which the subcarriers - 1, 0, 1 are DC (Direct current, direct current component), the left subcarrier-122 to subcarrier-2 and theright subcarrier 2 tosubcarrier 122 are used to carry data information, that is, 242 subcarriers are used to carry data. information. Subcarrier-128 to subcarrier-123 and subcarrier 123 to subcarrier 128 are guard bands. Therefore, the 242 sub-carriers usually used to carry data information are divided into 9 sub-resource blocks, each sub-resource block includes 26 sub-carriers, and 8 unused sub-carriers are left. In addition, the sub-resource block located in the center of the bandwidth spans the DC (ie, includes sub-carriers-1, 0, 1), and the method of the embodiment of the present invention mainly involves the allocation of 242 sub-carriers for carrying data information.

对于不同带宽的频域资源，其能够包括的资源块的类型相异。具体的，无线局域网遵循的下一代协议中约定了针对各种待分配频域资源(20MHz、40MHz、80MHz，或者160MHz)的可能被划分的资源块位置。For frequency domain resources of different bandwidths, the types of resource blocks that can be included are different. Specifically, the next-generation protocol followed by the wireless local area network stipulates resource block positions that may be divided for various to-be-allocated frequency domain resources (20MHz, 40MHz, 80MHz, or 160MHz).

以20MHz带宽的频域资源为例，20MHz带宽的频域资源可能被划分的资源块为26资源块，52资源块，106资源块或242资源块，其中，26资源块表示以26个子载波为一个资源块，即位于图14所示的资源块位置#0，资源块位置#7～位置#10及位置#11～位置#14的资源块。52资源块表示以52个子载波为一个资源块，即位于图14所示位置#1～位置#4的资源块。106资源块表示以106个子载波为一个资源块，即位于图14所示位置#5和位置#6的资源块。242资源块表示以242个子载波为一个资源块，即位于图14所示第4层整个资源块(位置#15的资源块)。一个20MHz带宽的频域资源可以由上述几种资源块组合而成。20MHz带宽以中间26资源块对称(如图14中的位置#0资源块)。Taking a frequency domain resource with a bandwidth of 20MHz as an example, the frequency domain resources with a bandwidth of 20MHz may be divided into 26 resource blocks, 52 resource blocks, 106 resource blocks or 242 resource blocks. One resource block is a resource block located at resourceblock position #0, resourceblock positions #7 to position #10, and position #11 toposition #14 shown in FIG. 14 . The 52 resource blocks indicate that 52 subcarriers are used as one resource block, that is, the resource blocks located atpositions #1 to #4 shown in FIG. 14 . The 106 resource blocks indicate that 106 subcarriers are taken as one resource block, that is, the resource blocks located at positions #5 and #6 shown in FIG. 14 . The 242 resource block means that 242 subcarriers are taken as one resource block, that is, the entire resource block (the resource block at position #15) located in the fourth layer shown in FIG. 14 . A frequency domain resource with a bandwidth of 20MHz can be composed of the above-mentioned resource blocks. The 20MHz bandwidth is symmetrical with the middle 26 resource blocks (position #0 resource block in Figure 14).

其中，示例性的，20MHz带宽的频域资源可以被划分成由图14中4层中的任意资源块的组合，比如由位置#0，位置3，位置4和位置5组成。每个站点只能分配其中一个划分出的资源块，即每个站点被分配到的资源块有16种可能。Wherein, exemplarily, the frequency domain resource of 20MHz bandwidth can be divided into a combination of any resource blocks in the 4 layers in FIG. Each station can only be allocated one of the divided resource blocks, that is, there are 16 possibilities for the resource blocks allocated to each station.

同理，以40MHz带宽的频域资源为例，40MHz带宽的频域资源是由2个20MHz带宽的频域资源的和。40MHz带宽的频域资源可能被划分的资源块为26资源块(如图15中位置#G资源块)，52资源块(如图15中的位置#E资源块)，106资源块(如图15中的位置#C资源块)，242资源块(如图15中的位置#A资源块)或484资源块(如图15中的第5层的整个资源块，位置#H的资源块)中一个或多个资源块的组合。Similarly, taking a frequency domain resource with a bandwidth of 40 MHz as an example, the frequency domain resource with a bandwidth of 40 MHz is the sum of two frequency domain resources with a bandwidth of 20 MHz. The frequency domain resources of 40MHz bandwidth may be divided into 26 resource blocks (as shown in Figure 15, location #G resource block), 52 resource blocks (as shown in Figure 15, location #E resource block), and 106 resource blocks (as shown in Figure 15). 15), 242 resource blocks (as shown in position #A resource block in Figure 15) or 484 resource blocks (as shown in Figure 15, the entire resource block of layer 5, the resource block at position #H) A combination of one or more resource blocks.

80MHz带宽的频域资源是由2个40MHz带宽的频域资源以及中间一个26资源块的和，80MHz带宽的频域资源可能被划分的资源块为26资源块(如图16中的位置#h资源块)，52资源块(如图16中的位置#g资源块)，106资源块(如图16中的位置#e资源块)，242资源块(如图16中的位置#c资源块)，484资源块(如图16中的位置#a资源块)或996资源块(如图16中的第6层的整个资源块，位置#i的资源块)中一个或多个资源块的组合。80MHz带宽以中间26资源块对称(如图16中的位置#00资源块)。The frequency domain resource of 80MHz bandwidth is the sum of 2 frequency domain resources of 40MHz bandwidth and a 26 resource block in the middle. The frequency domain resource of 80MHz bandwidth may be divided into 26 resource blocks (position #h in Figure 16). resource blocks), 52 resource blocks (as shown in the position #g resource block in Figure 16), 106 resource blocks (as shown in the position #e resource block in Figure 16), 242 resource blocks (as shown in the position #c resource block in Figure 16) ), 484 resource blocks (as shown in the position #a resource block in Figure 16) or 996 resource blocks (as shown in Figure 16, the entire resource block oflayer 6, the resource block at position #i) in one or more resource blocks combination. The 80MHz bandwidth is symmetrical with the middle 26 resource blocks (position #00 resource block in Figure 16).

160MHz带宽的频域资源是由2个80MHz带宽的频域资源的和。160MHz带宽的频域资源可能被划分的资源块为26资源块，52资源块，106资源块，242资源块，484资源块，996资源块或2*996资源块中一个或多个资源块的组合。160M资源块大小与位置与80M资源块位置类似，这里，为了避免赘述，省略其详细说明。The frequency domain resource of 160MHz bandwidth is the sum of two frequency domain resources of 80MHz bandwidth. The frequency domain resources of 160MHz bandwidth may be divided into resource blocks of 26 resource blocks, 52 resource blocks, 106 resource blocks, 242 resource blocks, 484 resource blocks, 996 resource blocks or 2*996 resource blocks. combination. The size and location of the 160M resource block are similar to the location of the 80M resource block. Here, in order to avoid redundant description, the detailed description thereof is omitted.

以上，列举说明了各种待分配频域资源可能被划分的资源块位置，下面，对基于可能被划分的资源块位置生成资源调度信息的过程进行详细说明。In the above, various resource block positions to which the frequency domain resources to be allocated may be divided are listed and explained, and the following describes the process of generating resource scheduling information based on the position of the possibly divided resource blocks in detail.

实施例5Example 5

本发明实施例提供一种资源分配方法，如图27所示，该方法包括：An embodiment of the present invention provides a resource allocation method, as shown in FIG. 27 , the method includes:

S2001、发送端生成资源调度信息。S2001. The sending end generates resource scheduling information.

其中，资源调度信息包括资源分配比特序列，资源分配比特序列用于指示站点被分配到的资源块。The resource scheduling information includes a resource allocation bit sequence, and the resource allocation bit sequence is used to indicate a resource block to which a station is allocated.

具体的，资源调度信息位于站点信息中。其中站点信息包括站点标识信息(一种较优站点标识信息为站点的关联标识)，发送功率，资源调度信息，空间流数起始位置，空间流数，数据传输采用的调制与编码策略(MCS，Modulation and Coding Scheme)，编码类型，是否使用时分空时码(STBC)指示，是否使用波束成型技术(Beamforming)指示，业务类型等参数中的一个或多个。Specifically, the resource scheduling information is located in the site information. The site information includes site identification information (a preferred site identification information is the associated identification of the site), transmission power, resource scheduling information, the starting position of the number of spatial streams, the number of spatial streams, and the modulation and coding strategy (MCS) adopted for data transmission. , Modulation and Coding Scheme), coding type, whether to use time division space-time code (STBC) indication, whether to use beamforming technology (Beamforming) indication, one or more of the parameters such as service type.

示例性的，资源分配比特序列由下述至少一类比特位组成，其可能包括的各类比特位的含义具体可以包括：Exemplarily, the resource allocation bit sequence is composed of the following at least one type of bits, and the meanings of the various types of bits it may include may specifically include:

资源分配比特序列的第一类比特位用于指示站点被分配的资源块是否小于等于242资源块，需要1比特位。或者第一类比特位用于指示站点被分配的资源块是否小于242资源块，需要1比特位。The first type of bits in the resource allocation bit sequence is used to indicate whether the resource blocks allocated to the station are less than or equal to 242 resource blocks, and 1 bit is required. Or the first type of bit is used to indicate whether the resource block allocated by the station is less than 242 resource blocks, and 1 bit is required.

资源分配比特序列的第二类比特位用于指示站点被分配的资源块位于的20MHz起始位置。例如，无线局域网遵循的下一代协议中约定最大带宽为160MHz，即对应8个20MHz。因此，此时第二类比特最多需要3比特位。The second type of bits in the resource allocation bit sequence is used to indicate the 20MHz starting position where the resource block allocated by the station is located. For example, the next-generation protocol followed by the wireless local area network stipulates that the maximum bandwidth is 160MHz, that is, corresponding to eight 20MHz. Therefore, the second type of bits requires at most 3 bits at this time.

资源分配比特序列的第三类比特位用于指示站点被分配的资源块为20MHz内的哪个可能被划分成的资源块。例如，无线局域网遵循的下一代协议中20MHz可能被划分的资源块的大小包括26资源块，52资源块，106资源块和242资源块，共有16种可能被划分的资源块。因此，此时第三类比特需要4比特位。在该例子中，第三类比特可以通过下述一个4比特的表1指示，但第三类比特与站点被分配到在20MHz内的资源块。又例如20MHz可能被划分的资源块的大小除242资源块，包括26资源块，52资源块和106资源块，共有15种可能被划分的资源块。The third type of bits in the resource allocation bit sequence is used to indicate which resource block within 20 MHz that the station is allocated can be divided into. For example, in the next-generation protocol followed by the wireless local area network, 20 MHz may be divided into 26 resource blocks, 52 resource blocks, 106 resource blocks and 242 resource blocks. There are 16 possible resource blocks. Therefore, the third type of bits requires 4 bits at this time. In this example, the third type of bits may be indicated by a 4-bit Table 1 below, but the third type of bits and stations are allocated to resource blocks within 20 MHz. For another example, the size of the resource blocks that may be divided for 20 MHz is divided by 242 resource blocks, including 26 resource blocks, 52 resource blocks and 106 resource blocks, and there are 15 kinds of resource blocks that may be divided.

表1Table 1

资源分配比特序列的第四类比特位用于指示站点被分配的资源块位于的40MHz起始位置。例如，无线局域网遵循的下一代协议中约定最大带宽为160MHz，即对应4个40MHz。因此，此时第四类比特最多需要2比特位。The fourth type of bits in the resource allocation bit sequence is used to indicate the 40MHz starting position where the resource block allocated by the station is located. For example, the maximum bandwidth agreed in the next-generation protocol followed by the wireless local area network is 160MHz, which corresponds to four 40MHz. Therefore, at most 2 bits are required for the fourth type of bits at this time.

资源分配比特序列的第五类比特位用于指示站点被分配的资源块位于的80MHz起始位置。例如，无线局域网遵循的下一代协议中约定最大带宽为160MHz，即对应2个80MHz。因此，此时第五类比特最多需要1比特位。The fifth type of bits in the resource allocation bit sequence is used to indicate the 80MHz starting position where the resource block allocated by the station is located. For example, in the next-generation protocol followed by the wireless local area network, the agreed maximum bandwidth is 160 MHz, that is, corresponding to two 80 MHz. Therefore, at most 1 bit is required for the fifth type of bit at this time.

资源分配比特序列的第六类比特位用于使得不同条件下(例如带宽或者实际被分配到的资源块)资源分配序列等长，即为保留比特位。The sixth type of bits in the resource allocation bit sequence is used to make the resource allocation sequence equal in length under different conditions (eg, bandwidth or actually allocated resource blocks), that is, reserved bits.

资源分配比特序列的第七类比特位用于指示站点被分配的资源块的大小是484资源块，996资源块还是2*996资源块，因此，此时第七类比特最多需要2比特位。或者第七类比特用于指示站点被分配的资源块的大小是242资源块，484资源块，996资源块还是2*996资源块。或者第七类比特用于指示站点被分配的资源块的大小是不是242资源块，是不是484资源块，是不是996资源块，是不是2*996资源块，相应的各需1比特The seventh type of bits of the resource allocation bit sequence is used to indicate whether the size of the resource block allocated by the station is 484 resource blocks, 996 resource blocks or 2*996 resource blocks. Therefore, at this time, the seventh type of bits requires at most 2 bits.

上述例子中，第一类比特用于指示站点被分配到的资源块是否小于等于20MHz带宽对应的242资源块。若第一类比特用于指示站点被分配到的资源块是否小于20MHz带宽对应的242资源块，则20MHz，40MHz，80MHz以及160MHz带宽下资源分配序列生成逻辑流程图分别如图21，图22，图23，图24所示，其他比特意义，表格等与上面实施例类似，不在此赘述。In the above example, the first type of bit is used to indicate whether the resource block allocated to the station is less than or equal to 242 resource blocks corresponding to a bandwidth of 20 MHz. If the first type of bit is used to indicate whether the resource block allocated to the station is smaller than the 242 resource blocks corresponding to the 20MHz bandwidth, the logic flow diagrams of the resource allocation sequence generation in the 20MHz, 40MHz, 80MHz and 160MHz bandwidths are shown in Figure 21, Figure 22, As shown in FIG. 23 and FIG. 24 , other bit meanings, tables, etc. are similar to the above embodiments, and are not repeated here.

There is no additional flow chart of bits indicating OFDMA or non-OFDMA, and Figure 26 refers to the flow chart of additional bits indicating OFDMA or non-OFDMA in addition to the site information. The resource allocation sequence also includes the eighth type of bits, other bit meanings, etc. Similar to the above embodiment, it is not repeated here. The bits included in the resource allocation sequence in other bandwidths can also be deduced by analogy, and details are not described here. Further, FIG. 25 and FIG. 26 can also use a method similar to Table 1 and Table 2, respectively listing a resource allocation sequence table of at least 8 bits, and the extra reserved bits can indicate other information.

示例性的，资源分配比特序列的含义具体可以包括：Exemplarily, the meaning of the resource allocation bit sequence may specifically include:

接收端找到包括自己站点标识的站点信息，然后解析该站点信息中的资源分配比特序列。The receiving end finds the site information including its own site identification, and then parses the resource allocation bit sequence in the site information.

资源分配比特序列解析存在2种方式，一种方式是结合接收到的带宽指示信息，得知资源分配序列的长度，例如20M带宽下，资源分配比特序列长度为4比特。另一种方式默认为所有带宽下的资源分配序列等长，例如资源分配序列长度为8比特。下面详述第一种方式，第二种方式的解析同第一种方式的160M解析过程一样。There are two ways to analyze the resource allocation bit sequence. One way is to combine the received bandwidth indication information to know the length of the resource allocation sequence. For example, in a 20M bandwidth, the length of the resource allocation bit sequence is 4 bits. Another way is that the length of the resource allocation sequence under all bandwidths is equal by default, for example, the length of the resource allocation sequence is 8 bits. The first method is described in detail below. The parsing process of the second method is the same as the 160M parsing process of the first method.

在第一种实施方式中，若带宽为20MHz时，则资源分配序列包括第三类比特，通过该4比特资源分配序列获知站点被分配的资源块为该20MHz内具体哪个可能被划分成的资源块。In the first embodiment, if the bandwidth is 20MHz, the resource allocation sequence includes the third type of bits, and through the 4-bit resource allocation sequence, it is known that the resource block allocated by the station is the specific resource within the 20MHz that may be divided into piece.

若带宽为40MHz时,则6比特的资源分配序列包括第一类比特，第二类比特，第三类比特和第六类比特中的至少一类。具体的，若第一类比特位为第一标识，则表示站点被分配的资源块小于等于242资源块，此时资源分配比特序列还包括第二类比特和第三类比特。1比特位的第二类比特位用来指示站点被分配的资源块位于该40MHz带宽下的20MHz起始位置。4比特位的第三类比特位用来指示站点被分配的资源块为该起始位置的20MHz内的具体哪个可能被划划分的资源块。If the bandwidth is 40 MHz, the 6-bit resource allocation sequence includes at least one of the first type of bit, the second type of bit, the third type of bit and the sixth type of bit. Specifically, if the first type of bit is the first identifier, it means that the resource blocks allocated to the site are less than or equal to 242 resource blocks, and the resource allocation bit sequence also includes the second type of bit and the third type of bit. The second type of 1-bit bit is used to indicate that the resource block allocated by the station is located at the starting position of 20MHz under the 40MHz bandwidth. The third type of 4-bit bit is used to indicate which resource block allocated by the station is a specific resource block that may be divided within 20MHz of the starting position.

若第一类比特位为第二标识，则表示站点被分配的资源块大于242资源块，此时该资源分配序列指示站点分配到的资源块为484资源块。资源分配序列其他5比特为保留比特位，即第六类比特。If the first type bit is the second identifier, it means that the resource blocks allocated to the station are larger than 242 resource blocks, and at this time, the resource allocation sequence indicates that the resource blocks allocated to the station are 484 resource blocks. The other 5 bits of the resource allocation sequence are reserved bits, that is, the sixth type of bits.

Specifically, if the extra bit indicates the downlink transmission at this time, or when the triggered uplink transmission is OFDMA transmission, the 5-bit resource allocation sequence includes the second type of bit and the third type of bit, wherein the 1-bit bit of the second type The bit is used to indicate that the resource block allocated by the station is located at the starting position of 20MHz under the 40MHz bandwidth. The third type of 4-bit bit is used to indicate which resource block allocated by the station is a specific resource block that may be divided within 20MHz of the starting position. If the extra bit indicates the downlink transmission at this time, or the triggered uplink transmission is non-OFDMA transmission, the resource allocation sequence does not exist, that is, non-OFDMA transmission is performed in the full bandwidth of 40MHz. When there is an additional bit indicating OFDMA or non-OFDMA transmission in addition to the station information, the logic flow diagram of the resource allocation sequence analysis when the bandwidth is 40MHz is shown in Figure 17, excluding the dashed block diagram.

若带宽为80MHz时,则7比特的资源分配序列包括第一类比特，第二类比特，第三类比特，第四类比特，第六类比特和第七类中的至少一类。具体的，若第一类比特位为第一标识，则表示站点被分配的资源块小于等于242资源块，此时资源分配比特序列还包括第二类比特的第二类比特位和第三类比特。2比特位的第二类比特位用来指示站点被分配的资源块位于该80MHz带宽下的20MHz起始位置。4比特位的第三类比特位用来指示站点被分配的资源块为该起始位置的20MHz内的具体哪个可能被划划分的资源块。If the bandwidth is 80 MHz, the 7-bit resource allocation sequence includes at least one of the first type of bit, the second type of bit, the third type of bit, the fourth type of bit, the sixth type of bit and the seventh type of bit.

The second type of 2-bit bits is used to indicate that the resource block allocated by the station is located at the starting position of 20MHz under the 80MHz bandwidth. The third type of 4-bit bit is used to indicate which resource block allocated by the station is a specific resource block that may be divided within 20MHz of the starting position.

The seventh type of 1-bit bit is used to indicate whether the size of the resource block to which the station is allocated is 484 resource blocks or 996 resource blocks. If the seventh type of bit is the first identifier, it means that the size of the resource block allocated to the site is 484 resource blocks. At this time, the resource allocation bit sequence also includes the fourth type of bit and the sixth type of bit. The fourth type of bits is used to indicate that the 484 resource block allocated to the station is located in the 484 resource block where the 40MHz starting position under the 80MHz bandwidth is located. At this time, the other 4 bits in the resource allocation sequence are reserved bits, that is, the sixth type of bits.

若第七类比特位为第二标识，则表示该站点被分配到的资源块的大小是996资源块。此时资源分配序列其他5比特为保留比特位，即第六类比特。If the seventh type of bit is the second identifier, it indicates that the size of the resource block to which the station is allocated is 996 resource blocks. At this time, the other 5 bits of the resource allocation sequence are reserved bits, that is, the sixth type of bits.

带宽为80MHz时的资源分配序列生成解析流程图如图18所示，其中图中站点被分配到资源块大小大于20MHz对应的242资源块时，需1比特指示484资源块还是996资源块。Figure 18 shows the resource allocation sequence generation and analysis flow chart when the bandwidth is 80MHz. In the figure, when a station is allocated to 242 resource blocks with a resource block size greater than 20MHz, 1 bit is required to indicate 484 resource blocks or 996 resource blocks.

If the first type of bit is the second identifier, it indicates that the size of the resource block allocated to the station is greater than 242 resource blocks, and at this time, the resource allocation bit sequence further includes the fourth type of bit and the sixth type of bit. The fourth type of 1-bit bit is used to indicate that the resource block to which the station is allocated is located in the 484 resource block corresponding to the 40MHz starting position under the 80MHz bandwidth.

若第七类比特位为第二标识，则表示该站点被分配到的资源块的大小是996资源块，此时资源分配比特序列还包括第五类比特和第六类比特，1比特位的第五类比特用来指示该站点被分配到的996资源块位于该160MHz带宽下的80MHz起始位置所在的996资源块。此时资源分配序列其他5比特为保留比特位，即第六类比特。If the seventh type of bit is the second identifier, it means that the size of the resource block allocated to the site is 996 resource blocks. At this time, the resource allocation bit sequence also includes the fifth type of bit and the sixth type of bit. The fifth type of bits is used to indicate that the 996 resource blocks allocated to the station are located in the 996 resource blocks where the starting position of 80 MHz is located under the 160 MHz bandwidth. At this time, the other 5 bits of the resource allocation sequence are reserved bits, that is, the sixth type of bits.

站点信息外存在额外指示OFDMA或非OFDMA传输的比特时，带宽为160MHz时的资源分配序列解析逻辑流程图如图19所示，其中图中站点被分配到资源块大小大于20MHz对应的242资源块时，有1比特指示484资源块还是996资源块，且不包含虚线框图。When there is an extra bit indicating OFDMA or non-OFDMA transmission outside the station information, the logic flow chart of the resource allocation sequence analysis when the bandwidth is 160MHz is shown in Figure 19, in which the station is allocated to the 242 resource blocks corresponding to the resource block size greater than 20MHz. , there is 1 bit to indicate 484 resource blocks or 996 resource blocks, and does not include a dashed block diagram.

其中，2比特指示484资源块，996资源块还是2*996资源块，一种实施方式是直接通过2比特对应的4种标识值中的3中标识值指示484资源块，996资源块还是2*996资源块。另外一种实施方式，可以通过图20的逻辑图解析。Among them, 2 bits indicate 484 resource blocks, 996 resource blocks or 2*996 resource blocks. One implementation is to directly indicate 484 resource blocks, 996 resource blocks or 2 by identifying 3 of the 4 identification values corresponding to 2 bits. *996 resource blocks. Another implementation can be analyzed through the logic diagram of FIG. 20 .

上述例子中，第一类比特用于指示站点被分配到的资源块是否小于等于20MHz带宽对应的242资源块。若第一类比特用于指示站点被分配到的资源块是否小于20MHz带宽对应的242资源块，则20MHz，40MHz，80MHz以及160MHz带宽下资源分配序列解析逻辑流程图分别如图21，图22，图23，图24所示，其他比特意义等与上面实施例类似，不在此赘述。In the above example, the first type of bit is used to indicate whether the resource block allocated to the station is less than or equal to 242 resource blocks corresponding to a bandwidth of 20 MHz. If the first type of bit is used to indicate whether the resource block allocated to the station is smaller than the 242 resource blocks corresponding to the 20MHz bandwidth, the logic flow chart of the resource allocation sequence analysis in the 20MHz, 40MHz, 80MHz and 160MHz bandwidths is shown in Figure 21, Figure 22, As shown in FIG. 23 and FIG. 24 , the meanings of other bits and the like are similar to the above embodiments, and will not be repeated here.

以上实施例都是否小于或小于等于20MHz对应的242资源块进行分层指示。本发明另一种方式还可以以是否小于或小于等于106资源块进行分层指示，160MHz带宽下资源分配序列解析逻辑流程图分别如图25或26所示，其中图25是指在站点信息外没有额外指示OFDMA还是非OFDMA的比特下流程图，而图26是指在站点信息外有额外指示OFDMA还是非OFDMA的比特下流程图，其他比特意义等与上面实施例类似，不在此赘述。其他带宽下的资源分配序列包含的比特也可以依次类推，不在此赘述。In the above embodiments, whether the 242 resource blocks corresponding to 20 MHz are less than or equal to or less than 20 MHz is indicated in layers. Another method of the present invention can also perform hierarchical indication based on whether it is less than or less than or equal to 106 resource blocks. The logic flow chart of resource allocation sequence analysis under 160MHz bandwidth is shown in Figure 25 or 26, respectively, where Figure 25 refers to outside the site information. There is no additional flow chart of bits indicating OFDMA or non-OFDMA, and Figure 26 refers to the flow chart of additional bits indicating OFDMA or non-OFDMA in addition to the site information. The bits included in the resource allocation sequence in other bandwidths can also be deduced by analogy, and details are not described here.

Based on the description of the above embodiments, the transmitting end can generate resource scheduling information including resource allocation bit sequences, wherein the resource allocation bit sequences indicating the resource blocks to which the station is allocated under bandwidths of 20MHz, 40MHz, 80MHz and 160MHz respectively require 4, 6 (or 5), 7 and 8 bits, or any sequence of resource allocation bits at any bandwidth that indicates the resource block to which a station is allocated requires 8 bits. The resource allocation sequence uses a number of logical bits and a small 4-bit table, which reduces the memory storage requirement for site equipment compared to the 8-bit table that may be required to directly list all allocated resource blocks. It is worth noting that several logical bits and 4-bit small tables used in the present invention can also be presented in a large 8-bit table, and the logical bits are easy to help a site to quickly look up the table to know which resource block is allocated to.
