在一些实施例中，第一NDPA帧包括第二信息域，第二信息域用于指示第一NDPA帧的格式为dRU NDPA格式，也即用于指示第一NDPA帧为用于分配下行dRU的NDPA帧。
其中，第二信息域可以为特殊的用户信息(special user info)域，第二信息域可通过第二值指示第一NDPA帧的格式为dRU NDPA格式。
在一些实施例中，第一NDPA帧包括STA信息列表(STA Info List)域，STA信息列表域包括至少一个STA信息(STA Info)域，每个STA信息域与一个STA相对应，用于向其分配下行dRU。
在一些实施例中，每个STA信息域包括dRU分配(dRU allocation)子域，每个STA信息域包括的dRU分配子域用于向相应STA分配下行dRU。
其中，每个STA信息域中的dRU分配子域可以通过至少一个比特位指示向对应STA分配的下行dRU。
例如，每个STA信息域中的dRU分配子域可通过7个比特位指示向对应STA分配的下行dRU。
其中，AP通过第一NDPA帧向各个STA分配的下行dRU分别对应不同的dRU索引值，也即AP向各个STA分配的下行dRU互不相同。
在一些实施例中，AP向每个STA分配的下行dRU的格式可以为以下至少一项：
26-tone-dRU；
52-tone-dRU；
106-tone-dRU；

其中，26-tone-dRU+52-tone-dRU、26-tone-dRU+106-tone-dRU以及52-tone-dRU+106-tone-dRU为多分布式资源单元(multiple dRU，M-dRU)。
其中，52-tone-dRU＝26-tone-dRU+26-tone-dRU。
其中，106-tone-dRU＝52-tone-dRU+52-tone-dRU+2null tones。
其中，242-tone-dRU＝106-tone-dRU+106-tone-dRU+26-tone-dRU+4null tones。
其中，484-tone-dRU＝242-tone-dRU+242-tone-dRU。
在一些实施例中，AP向每个STA分配的下行dRU与STA的工作带宽相关，STA的工作带宽包括20MHz、40MHz、80MHz、160MHz或者320MHz，160MHz可以为(80MHz+80MHz)。
其中，STA的工作带宽可以理解为AP与STA进行下行数据传输时STA的信道带宽或工作带宽。
其中，每个工作带宽可以对应至少一种dRU格式，AP向每个STA分配下行dRU时，可采用该STA的工作带宽所对应的一种或者多种dRU格式进行下行dRU的分配。
例如，当STA的工作带宽为20MHz时，AP可采用26-tone-dRU、52-tone-dRU、106-tone-dRU等dRU格式的一种或者多种组合向STA分配下行dRU，或者可采用26-tone-dRU+52-tone-dRU的M-dRU格式向STA分配下行dRU。
例如，当STA的工作带宽为40Mhz时，AP可采用26-tone-dRU、52-tone-dRU、106-tone-dRU、242-tone-dRU等dRU格式的一种或者多种组合向STA分配下行dRU，或者可采用26-tone-dRU+52-tone-dRU、26-tone-dRU+106-tone-dRU或者52-tone-dRU+106-tone-dRU的M-dRU格式向STA分配下行dRU。
例如，当STA的工作带宽为80MHz时，AP可采用26-tone-dRU、52-tone-dRU、106-tone-dRU、242-tone-dRU、484-tone-dRU等dRU格式的一种或者多种组合向STA分配下行dRU，或者可采用上述任意M-dRU格式向STA分配下行dRU。
例如，当STA的工作带宽为160MHz时，AP可采用26-tone-dRU、52-tone-dRU、106-tone-dRU、242-tone-dRU、484-tone-dRU等dRU格式的一种或者多种组合向STA分配下行dRU，或者可采用上述任意M-dRU格式向STA分配下行dRU。
在一些实施例中，每个STA信息域中的dRU分配子域可通过至少一个比特位指示向相应STA分配的下行dRU的dRU起始索引值，dRU起始索引值用于指示波束形成器(beamformer)请求反馈的第一个26-tone-dRU。
每个STA信息域中的dRU分配子域可通过至少一个比特位指示向相应STA分配的下行dRU的dRU结束索引值，dRU结束索引值用于指示波束形成器(beamformer)请求反馈的最后一个26-tone-dRU。
在一些实施例中，每个STA信息域包括列数Nc子域，Nc子域用于指示AP与相应STA进行下行数据传输时的空间流(Spatial Stream，SS)的数量。
在一些实施例中，每个STA信息域包括反馈类型及列数(Feedback Type And Ng)子域，所述反馈类型及列数子域用于指示相应STA的反馈类型以及下行dRU的子载波分组子载波分组。
其中，反馈类型包括单用户(Single User，SU)类型、多用户(Multiple User，MU)类型或者信道质量指示(Channel Quality Indicator，CQI)类型。
在一些实施例中，每个STA信息域还包括关联标识符(Association Identifier，AID)子域，关联标识符域用于指示AP为相应STA分配的AID。
其中，由于每个STA分别对应不同的AID，因此每个STA信息域可通过关联标识符域所指示的AID来区分不同的STA.
例如，当每个STA信息域包括dRU分配子域时，每个STA信息域中的dRU分配子域与关联标识符子域相对应。也即，每个STA信息域通过关联标识符域指示：STA信息域中的dRU分配子域用于向STA信息域中关联标识符所指示的AID所对应的STA分配下行dRU。
步骤S32，AP发送第一NDPA帧。
在一些实施例中，AP可发送第一NDPA帧，以使第一STA接收到第一NDPA帧之后，可确定AP向自己分配的下行dRU，进而根据AP分配的下行dRU与AP进行下行数据传输。
在一些实施例中，AP通过第一NDPA帧向至少一个STA分配下行dRU之后，可在向每个STA分配的下行dRU上向相应STA发送NDP帧。
