Abstract
A wireless local area network (WLAN) having stations (STAs) using Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA) in which at least some stations support Full Duplex (FD) transmission. Mechanisms are described in which a STA can send a preemption request to a station performing ongoing transmissions. The preempted STA detects a preemption request of this preempting STA. The preempted STA interrupts its ongoing transmission; if it has determined to accept the preemption request. Thus, the preempting STA preempts the transmission of the preempted STA, to send a preemptive transmission, after receiving notification that the preempted STA has interrupted its ongoing transmission.
