Abstract
An enhanced method of handling block Acks, such as for latency sensitive traffic streams, for which a separate block Ack mechanism is established, which is separate from other traffic in the same TID. With this separate block Ack mechanism the recipient STA can have an independent receive reordering buffer control for latency sensitive traffic, so that the MSDU or A-MSDU of latency sensitive traffic can be passed to the next MAC process in order of increasing sequence number of the MSDUs or A-MSDUs since those MSDUs and A-MSDUs have the same QoS requirement, such as the latency time. This mechanism reduces the chances of latency sensitive traffic being stuck in a receive reordering buffer behind other traffic in the TID and having its traffic expire.
