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.

Abstract: Disclosed herein are methods and apparatus for the communication of wireless data using diverse radio access technologies (RATs) in Television Band (TVBD) frequencies. An architecture for communicating wireless data in TVBD frequencies may include one or more network nodes that perform functions related to the coordination of channel quieting across multiple diverse RATs. Channel quieting may be performed across multiple diverse RATs by using temporary channel reassignments, by aggregating wireless transmit/receive units (WTRUs) that use a particular RAT onto the same channel, and/or via other techniques.

Abstract: A method and system is disclosed for communicating data using diverse radio access technologies (RATs) in a wireless communication system. A wireless transmit/receive unit (WTRU) may transmit data over a first channel using a first radio access technology (RAT) and a network node may receive information that indicates that the WTRU is operating on the first channel using the first RAT. The network node may determine, based on the RAT being used by the WTRU, that the WTRU should move to a second channel prior to a quiet period on the first channel. The network node may transmit a first command to the WTRU that indicates that the WTRU should move to the second channel. The WTRU may move from the first channel to the second channel in response to receiving the first command and the WTRU may transmit data over the second channel using the first RAT.
