    Abstract: A method and apparatus is described herein for performing loop power control and transmission power control (TPC) in a wireless network. Described herein are methods including using separate power control loops for communication with an entire wireless network and for point-to-point (P2P) transmissions and separate power control loops for omni-directional and directional beamformed transmissions. Also described herein are methods and apparatuses for requesting clear channel assessment (CCA) measurements and adjusting CCA thresholds and transmission power based on the reported measurements. Methods and apparatuses are also described wherein access points (APs) coordinate transmission power to reduce interference with each other and to determine optimal transmission power to each mobile station (STA).

    Abstract: Methods and apparatuses are described herein for adapting clear channel assessment (CCA) thresholds with or without Transmit Power Control (TPC) are disclosed. An IEEE 802.11 station (STA) may dynamically calculate a STA specific transmit power control (TPC) value and a STA specific clear channel assessment (CCA) value based on a target TPC parameter and a target CCA parameter. The target TPC parameter and the target CCA parameter may be received from an IEEE 802.11 cluster head configured to control TPC and CCA for a plurality of STAs associated with the BSS. The target TPC parameter and the target CCA parameter also may be related. The STA may then determine whether a carrier sense multiple access (CSMA) wireless medium of a wireless local area network (WLAN) basic service set (BSS) is occupied or idle based on the STA specific CCA value.

    Abstract: Device, systems, and/or techniques for using sub-channel signaling information between an access point and a first station are disclosed. An uplink trigger sent from the access point to the first station may be received. A map may be transmitted from the first station indicating at least one sub-channel that is available for spatial sharing by a second station. The first station may receive an acknowledgement from the access point that data was transmitted from the second station on the at least one sub-channel and/or received by the at least one access point. An OFDMA transmission having a sub-channel/sub-band available for transmitting data may be determined. An energy in the sub-channel/sub-band may be measured and/or compared to a dynamic and/or static threshold. Whether a sub-channel/sub-band is free or busy may be determined for example based on if the measured energy is, or is not, greater than the threshold.

    Abstract: Systems, methods, and instrumentalities are disclosed for range extension, basic service set (BSS) color labeling, and multi-user (MU) fragmentation and control in WLANs. A range extension notification/enablement scheme, a clear channel assessment (CCA), a headroom indication, and/or power scaling may be provided for a range extension mode. BSS color may be provided for multiple-BSSs under an access point (AP). Uplink (UL) transmission may be provided with different fragmentation capabilities. A high-efficiency (HE) trigger-based UL NDP physical layer convergence protocol (PLCP) protocol data unit (PPDU) frame may be provided. A station (STA) may receive a trigger frame comprising a null data packet (NDP) indication and a trigger type. The STA may determine that the STA is an intended recipient of the trigger frame. The STA may prepare an NDP PPDU for a control frame and/or a management frame based on the trigger type.
