Abstract: Systems, methods, and instrumentalities are disclosed to desynchronize transmissions in group-based operations. A group user equipment (UE), e.g., a UE that is a member of a group of UEs, may be in an inactive mode. The group UE may receive a multicast message indicating that the group UE may enter an active mode. For example, the group UE may use the active mode for periodic reporting of its monitoring activity to the network. The multicast message may indicate a mechanism for the group UE to use to send an uplink transmission to the network. The group UE may send the uplink transmission to the network at a transmission time indicated by the mechanism. The transmission time may be desynchronized from other UEs in the group.

Abstract: A method and apparatus are disclosed for enabling high-efficiency communication in wireless local area network (WLAN) systems. A station (STA) may receive an Uplink Priority List (UPL) from an access point (AP). In one example embodiment, a STA may send a request for prioritized access to an AP. The STA may then receive an ordered queue of STAs granted contention free prioritized access in a predetermined time interval, which may be referred to as the Exclusive Priority Access (EPA) period. The STA may then determine whether it is identified in the ordered queue of STAs granted prioritized access. The STA may then access a medium such as a Carrier Sense Multiple Access (CSMA) wireless medium associated with the IEEE 802.11 network, in turn with other STAs in the ordered queue per the queue order during the predetermined time interval using an inter-frame spacing, thereby enabling contention free access.
