Abstract
Systems, apparatus and methods for wireless local area network (WLAN) communication which support real-time application (RTA) packets. The access point (AP) schedules multiple-user (MU) multiple-input-multiple-output (MIMO) transmissions for uplink (UL) or downlink (DL) for RTA packets by allocating resources to packet transmissions before RTA packet arrival. The AP contends for channel access before the expected time of arrival of the RTA packet in the DL or UL direction. The operations reduce RTA packet latency on the WLAN.
