Title:
SHARING AN EDCA TXOP WITH RTA TRAFFIC
Document Type and Number:
WIPO Patent Application WO/2022/208211
Kind Code:
A3
Abstract:
A communication circuit and protocol for a wireless local area network (WLAN) using single EDCA and/or Multiple-User (MU) EDCA in which frames for Real Time Applications (RTA) can utilize shared Transmit Opportunities (TXOPs) to reduce transmission latencies. The protocol is configured in a number of ways to ensure communication fairness, such as by ensuring a minimum required channel resource is provided for transmitting frames from the primary AC during the TXOP. AP MLDs and non-AP MLDs are also supported and can exchange information on distinguishing traffic streams from other traffic streams having the same Traffic Identifier (TID), in determining which links to use for transmitting the traffic stream.
