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.
