    • A communication device determines, in connection with a prior uplink multi- user (UL MU) communication in which the communication device participated, whether the communication device is to use one or more first channel access parameters, or one or more second channel access parameters for accessing a communication medium for a single user (SU) transmission by the communication device, where using the one or more first channel access parameters is associated with a greater probability of obtaining access to the communication medium as compared to using the one or more second channel access parameters. Depending on the determination made, the communication device uses the one or more first channel access parameters, or the one or more second channel access parameters to attempt to access the communication medium. In response to accessing the communication medium, the communication device transmits the SU transmission via the communication medium.
    • 通信设备结合通信设备参与的先前上行链路多用户(UL MU)通信来确定通信设备是要使用一个或多个第一信道接入参数,或者 一个或多个第二信道接入参数,用于访问通信设备的用于单用户(SU)传输的通信介质,其中使用所述一个或多个第一信道接入参数与被比较的通信介质获得接入的更大可能性相关联 使用一个或多个第二信道接入参数。 取决于所做的确定,通信设备使用一个或多个第一信道接入参数或者一个或多个第二信道接入参数来尝试接入通信介质。 响应于访问通信介质,通信设备经由通信介质发送SU传输。

    • A method is described. A block allocation that indicates a plurality of contiguous tone blocks of a wireless local area network communication channel is selected for a multi-user, multiple input multiple output (MU-MIMO) orthogonal frequency division multiple access (OFDMA) data unit. A contiguous tone block corresponds to a respective device set having at least one communication device. Respective spatial stream allocations are selected, for at least some of the blocks, that indicate a number of spatial streams for the corresponding block of the data unit. The number of streams of a block is equal to a number of communication devices of the device set that corresponds to the block. A first field is encoded and transmitted to indicate the selected block allocation and the selected spatial stream allocations. A second field is encoded and transmitted to indicate a respective device identifier for each communication device of the respective device sets.
    • 描述了一种方法。 对于多用户多输入多输出(MU-MIMO)正交频分多址(OFDMA)数据单元,选择指示无线局域网通信信道的多个连续音调块的块分配。 连续的音调块对应于具有至少一个通信设备的相应设备组。 对于指示数据单元的相应块的空间流的数量的至少一些块,选择相应的空间流分配。 块的流数等于与块相对应的设备组的通信设备的数量。 编码和发送第一字段以指示所选择的块分配和所选择的空间流分配。 编码和发送第二字段以指示相应设备组的每个通信设备的相应设备标识符。
