    • Simultaneous, multi-user uplink communication is scheduled in a wireless network by transmitting a poll message to a plurality of access terminals in response to receiving a first request to transmit data via uplink. The poll message includes a solicitation for requests to transmit data from each of the plurality of access terminals. The poll message also includes a medium reservation and schedule for transmission of the requests from the access terminals. Based on the requests received from the access terminals, a number of the access terminals are selected for simultaneous transmission of data via uplink. A transmit start message is sent to each of the selected access terminals indicating when and for how long the selected access terminals may transmit data via uplink. After the data is received, a block ACK message is sent to each of the selected access terminals indicating successful simultaneous communication.
    • 响应于接收到经由上行链路传输数据的第一请求,通过向多个接入终端发送轮询消息,在无线网络中调度同时多用户上行链路通信。 轮询消息包括用于从多个接入终端中的每一个发送数据的请求的请求。 轮询消息还包括用于从接入终端发送请求的媒体预留和时间表。 基于从接入终端接收的请求,选择多个接入终端用于经由上行链路的数据的同时发送。 发送开始消息被发送到每个所选择的接入终端,指示所选择的接入终端何时以及多长时间可以经由上行链路传输数据。 在接收到数据之后,向指示成功的同时通信的所选择的接入终端中的每一个发送块ACK消息。
