Abstract: Methods and apparatus for channel state information sounding and feedback are provided. In an aspects, a first message is transmitted to one or more wireless communication devices requesting channel state information. In accordance with this aspects, the first message comprises a header and a payload, the header comprising a plurality of fields of a first field type which are useable to determine the channel state information, and the payload comprising parameters for estimating the channel state information. In certain aspects, the channel state information parameters are also provided in the header of the first message. In various aspects a second message comprising the channel state information is received from the one or more wireless communication devices. In one aspect, the first message is a physical layer convergence protocol data unit (PPDU), and the first field type is a long training field (LTF).

Abstract: Methods and systems of providing uplink (UL) transmission power control are provided. The UL transmission power control is provided between access points (APs) and wireless stations in a multi-user (MU) unlicensed wireless network. The disclosed method includes participating in a first wireless communication between an AP and at least one station of a plurality of stations in an unlicensed wireless network, and using an uplink UL transmission power parameter transmitted from the AP to the at least one station to regulate UL power control of UL transmissions between the at least one station and the AP.

Abstract: Systems and methods are disclosed that may communicate a control aggregate frame from a first wireless device to a second wireless device. A first wireless device may form a control aggregate frame by aggregating a plurality of first control frames into the control aggregate frame. The control aggregate frame may include a single media access control (MAC) header, a plurality of first aggregation fields, each storing a control frame subtype for a corresponding one of the plurality of first control frames, and a plurality of first payload fields, each storing a corresponding one of the plurality of first control frames. After generating the control aggregate frame, the first wireless device may transmit it to the second wireless device.

Abstract: A system and method for wireless devices to efficiently receive communications by transmitting and receiving specialized beacon messages. Particularly, a wireless device may await reception of a synchronizing beacon message from a transmitting device. A relative position identifier within the synchronizing beacon message may then allow the wireless device to anticipate future beacon message transmissions and to synchronize its reception pattern with the transmitter. In this manner the wireless device need only receive and decode beacon messages germane to its operation.

Abstract: A method for reduced overhead paging by an access point is described. The method includes assigning at least one paging identifier to at least one station. The method also includes partitioning a paging identifier space into paging identifier sets. The method further includes generating a paging message based on at least one of the paging identifier sets and the at least one paging identifier. The method additionally includes sending the paging message.
