US 12,615,666 B2 · Managing EDCA parameters with low latency reliable traffic

Abstract

A network adopts Low Latency Reliable Service measures to ensure LLRS traffic has priority over not-LLRS traffic. LLRS capable and not-capable stations coexist and share the same wireless medium. LLRS not-capable stations complete an ongoing legacy contention free transmission TXOP regardless of any needs of station to transmit LLRS. LLRS transmissions thus wait for a long time before starting. An AP detects LLRS activity in the network and modify the EDCA TXOP limit parameter of a BSS to force the stations to reduce their TXOP while LLRS activity remains. The AP can organize a BSS for LLRS capable stations and another BSS for LLRS not-capable stations. Refusal for association to such BSSs or disassociation from such BSSs can include a code indicating to the refused/disassociated stations that a BSS more adapted to its LLRS capability is available.

Claims13

Dependent claims

A communication method in a wireless network, the communication method comprising, at an access-point, AP:

receiving capabilities from a non-access-point, non-AP, station;
determining whether a capability of the non-AP station matches a capability of a first Basic Service Set, BSS, with respect to a low latency reliable service, LLRS;
transmitting, to the non-AP station, an association-related management frame refusing an association of the non-AP station with the first BSS managed by the AP or disassociating the non-AP station from the first BSS, wherein the association-related management frame includes a code indicating another BSS managed by the AP is available,
wherein transmitting the association-related management frame is responsive to determining no match.
