Abstract

See full text

Methods and apparatuses are described herein for multiple access schemes for Wireless Local Area Network (WLAN) with full-duplex radios. For example, an access point (AP), in response to receiving a request to send (RTS) from a first station (STA), may transmit a full-duplex clear to send (FD CTS) to the first STA and a full-duplex request to send (FD RTS) to a second STA. In response to transmitting the FD RTS to the second STA, the AP may receive a clear to send (CTS) from the second STA. The AP may transmit, to both the first STA and the second STA, a FD trigger frame that includes scheduling information to enables FD communication with the first STA for uplink (UL) data and the second STA for downlink (DL) data at a same time. The scheduling information may include timing information and channel information for the FD communication.
