    • A method of operating an access point includes defining a restricted access window during which stations that belong to a same infrastructure basic service set as the access point are not allowed to transmit data frames. The method further includes generating a beacon announcing the restricted access window, and transmitting the beacon to the stations that belong to the same infrastructure basic service set as the access point. The method also includes, during the restricted access window, receiving a poll frame from a first station of the stations that belong to the same infrastructure basic service set as the access point. The method further includes, subsequent to the poll frame, transmitting a data frame to the first station.
    • 操作接入点的方法包括定义受限访问窗口,在该限制访问窗口期间,属于与接入点设置的相同基础设施基本服务的站不允许发送数据帧。 所述方法还包括生成指示所述受限访问窗口的信标,以及将所述信标发送到属于与所述接入点相同的基础设施基本服务集的站。 该方法还包括在受限访问窗口期间从属于与接入点相同的基础设施基本服务集的站的第一站接收轮询帧。 该方法还包括在轮询帧之后,将数据帧发送到第一站。

    • In a method for transmitting a data unit in a wireless communication network, a physical layer (PHY) preamble and a media access control layer (MAC) header are generated. In generating the MAC header, a first address field to include a first address and a second address field to include a second address are generated. The first, not globally unique, address indicates a communication device for which the data unit is intended or a communication device that is transmitting the data unit. The second address field indicates the other one of a communication device for which the data unit is intended or a communication device that is transmitting the data unit. The first address field and the second address field are included in the MAC header. The MAC header omits a globally unique address corresponding to the first address of the first address field.
    • 在用于在无线通信网络中发送数据单元的方法中,生成物理层(PHY)前导码和媒体访问控制层(MAC)报头。 在生成MAC报头时,生成包括第一地址和第二地址字段以包括第二地址的第一地址字段。 第一个而不是全球唯一的地址指示数据单元所针对的通信设备或正在发送数据单元的通信设备。 第二地址字段指示数据单元所针对的通信设备中的另一个或正在发送数据单元的通信设备。 第一地址字段和第二地址字段包括在MAC报头中。 MAC标头省略与第一地址字段的第一地址相对应的全局唯一地址。
