MULTI-USER UPLINK COMMUNICATION USING EDCA WITH POLLING

摘要

Simultaneous, multi-user uplink communication is scheduled in a wireless network (100) by transmitting a poll message (411) to a plurality of access terminals (403-406) in response to receiving a first request to transmit data (410) via uplink. The poll message (411) includes a solicitation for requests to transmit data from each of the plurality of access terminals (403-406). The poll message (411) 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 (403, 404) are selected for simultaneous transmission of data (418, 419) via uplink. A transmit start message (416) is sent to each of the selected access terminals (403, 404) indicating when and for how long the selected access terminals (403, 404) may transmit data via uplink. After the data (418, 419) is received, a block ACK message (422, 423) is sent to each of the selected access terminals (418, 419) indicating successful simultaneous communication.
