A wireless communication apparatus, method or protocol for wireless STAs using CSMA / CA on a wireless local area network (WLAN). A receiver STA receives MSDUs or A-MSDUs which include an expiration time, from a transmitter STA. The receiver STA stores the MSDUs or A-MSDUs with expiration time in its receive reordering buffer of the corresponding high-throughput (HT)-immediate block acknowledgement (Ack) agreement. The receiver STA passes the MSDU or A-MSDU to a next MAC process before an expiration time of the MSDU or A-MSDU. Thus, the percentage of latency sensitive traffic packets being communicated prior to expiration is increased.
