Abstract
Methods and apparatus for interference discovery for full-duplex data transmission are provided. In an embodiment, a station (STA) receives a full-duplex request message from an access point (AP). The STA transmits a first full-duplex response message to the AP. The STA listens for a second full-duplex response message transmitted from a second STA to the AP. The STA determines a received power of the second full-duplex response message from the second STA to the AP. The STA receives a first trigger message from the AP. The first trigger message includes information to perform full-duplex data transmission. The STA transmits data to the AP in response to the first trigger message. The STA transmits interference information to the AP. The interference information is based on the determined received power.
