US Patent 11895712 RTA contention collision avoidance

A wireless communication circuit for operating over a wireless local area network (WLAN) supporting carrier sense multiple access/collision avoidance (CSMA/CA) in which real time application (RTA) traffic and non-RTA traffic coexist. Channel time is scheduled for transmitting real-time application (RTA) traffic based on expected RTA packet arrival time, with the schedule being shared with neighboring stations. Schedule time is adjusted based on schedules of neighboring stations to prevent channel contention collisions of multiple RTA traffics contending for the channel. Various mechanisms are described for supporting RTA transmissions while reducing channel access latency and contention collision.
