Abstract: Mobile stations can query independent basic service set (BSS) parameters of a group of Access Points (APs) by setting a Pre-Association Message Exchange BSSID Independent (PAME-BI) bit during Wi-Fi discovery. The PAME-BI bit may be included in a Generic Advertisement Service (GAS) request to indicate that an Access Network Query Protocol (ANQP) request carried by the GAS request is querying both independent and dependent BSS parameters. In some embodiments, the PAME-BI bit is included as a field in the ANQP query, rather than the GAS request message.

Abstract: A method for transmitting to an access point includes receiving a selection condition and a selection contention period from the access point, and comparing the selection condition to a selection parameter. The method also includes contending for use of a transmission medium during the selection contention period if the selection parameter meets the selection condition.

Abstract: A method for beamforming training is disclosed including SNR values with each of the SNR values associated with one of the antenna identifiers (IDs) in a first frame identifying different radio frequency (RF) chains for a process of beamforming training; receiving and transmitting the first frame bi-directionally between multiple pairs of communicating nodes, wherein each pair of the communicating nodes has at least one initiator node and one responder node; receiving feedback of the SNRs associated with the antenna IDs from two or more responder nodes of the multiple pairs of the communicating nodes to choose an RF chain as favorable transmit antenna for transmission; and determining respective one from the multiple antenna sectors of the multiple antennas for transmission for the responder nodes according to the feedback. A central network controller and a system are also disclosed herein.

Abstract: A method and apparatus for wireless communications for relay communication are provided. The method includes a source node sets up one or more backup relay links between the source node and a destination node that comprises a route through one or more standby relay nodes; transmits a first frame to the one or more standby relay nodes to activate the one or more standby relay nodes, transmits a second frame from the source node to the destination node informing the destination node of a switch of the relay link. Apparatuses are provided thereof.

Abstract: Network signaling loads are controlled in a wireless network by monitoring traffic patterns at an access point and determining that the access point is a high turnover access point. A high turnover access point is determined based on an average time devices spend in a coverage area of the access point being below a threshold level. Beacon and/or probe response messages are generated that identify the access point as a high turnover access point. In addition, a turnover activity value may be generated for the access point and included in the beacon and/or response messages. A mobile device may determine whether to authenticate and associate with the access point based on the turnover activity value.

Abstract: Embodiments are provided herein for determining a synchronizing master for device-to-device (D2D) communication in a cellular network environment. In an embodiment, a user equipment (UE) receives a discovery signal comprising a timing reference, and determines a transmitter of the discovery signal. In accordance with the determination of the transmitter of the discovery signal, the UE performs one of synchronizing to the timing reference in the discovery signal and transmitting a second discovery signal. The UE performs the synchronizing to the timing reference if the transmitter of the discovery is a cellular network. Alternatively, the UE transmits the second discovery signal upon determining that the transmitter of the discovery signal is a second UE that is out of coverage of a cellular network.

Abstract: System and method embodiments are provided for differentiated fast initial link setup. The embodiments enable improved performance of initial link setup by stations in a wireless local area network during the association process and mitigate the negative effect of bursty association on existing associated users. In an embodiment, a method in a wirelessly enabled network component for differentiated fast initial link setup in a wireless local area network, includes determining categories of station types for initial link setup; determining initial link setup conditions for each station type, wherein the initial link setup conditions specify a priority of associating for each station type; and broadcasting initial link setup conditions to a plurality of stations, wherein the stations determine whether to associate with the wirelessly enabled network component immediately or after a time duration according to the station types and initial link setup conditions.
