Techniques for low latency communications in wireless local area networks

Abstract:

Techniques for implementing low latency communications in a wireless local area network are provided. A first wireless communication device may implement a low latency basic service set (BSS) that allows contention-based channel access over a portion of a bandwidth. The first wireless communication device may configure a primary channel and one or more secondary channels within an available bandwidth. Communications with one or more wireless communication devices that have data traffic associated with a quality of service (QoS) parameter may be provided over one or more of the secondary channels. A transmission from a second wireless communication device on the primary channel may be discarded by the first wireless communication device, or the first wireless communication device may take over channel access from the second wireless communication device if such a transmission overlaps with low latency transmissions on the one or more secondary channels.
