Abstract: A method of enabling data to be relayed between an access point (AP) and a target station (STA). The AP identifies the target STA based at least in part on a medium usage efficiency of the target STA. The AP further sends a relay selection trigger to the target STA to cause the target STA to broadcast a relay selection request to a set of candidate STAs. The relay selection request includes a set of metrics pertaining to a direct link between the AP and the target STA. The AP then receives one or more relay selection responses from one or more candidate STAs in the set of candidate STAs based at least in part on the set of metrics and selects a relay STA from the set of candidate STAs based at least in part on the one or more relay selection responses.

Abstract: A user terminal for multiple-user wireless communication is provided, comprising a transmit buffer configured to store uplink data for transmission. The user terminal comprises a processor configured to generate a request to transmit frame in response to uplink data being present in the transmit buffer, and initiate a transmit timer for determining when to transmit the request to transmit frame. The user terminal comprises a transmitter configured to transmit the request to transmit frame when the transmit timer expires or when the uplink data present in the transmit buffer exceeds a threshold amount. The user terminal comprises a receiver configured to receive a clear to transmit frame from an access point based on the transmitted request to transmit frame. The transmitter is further configured to transmit the uplink data present in the transmit buffer, concurrently with at least one other user terminal transmitting uplink data, to the access point at a specified time based on receiving the clear to transmit frame addressed to the user terminal.
