    摘要： An apparatus for wireless communications. The apparatus includes a network interface configured for wireless communication with one or more personal basic service set (PBSS) control points (PCPs)/access points (APs) within a basic service set (BSS) PCP/AP cluster (BPAC) BSS. A processor coupled to the network interface is configured to coordinate beam coverage functions of the one or more member PCP/APs within the BPAC BSS. The processor is also configured to schedule communications within the BPAC BSS. The processor is also configured to provide a function of a virtual PCP/AP, and/or instruct another PCP/AP within the BPAC BSS to provide a function of the virtual PCP/AP, the virtual PCP/AP providing a representation of all PCP/AP s in the BPAC BSS as the single virtual PCP/AP.

    摘要： Methods and systems for channel access in a BSS having two or more PCP/APs. A C-PCP/AP transmits at least a first management/extension frame, the management/extension frame including information for channel access by a STA. The C-PCP/AP receives, from the STA, at least a second management/extension frame. Based on information exchanged between the C-PCP/AP and the STA via at least the first and second management/extension frames, the STA is provided with channel access within the BSS by: the C-PCP/AP establishing a communication link for the C-PCP/AP to serve the STA; or the C-PCP/AP assigning a second PCP/AP in the BSS to serve the STA.

    摘要： Systems and methods for wireless discovery and connectivity in 802.11 networks. A management frame from an access point (AP) or personal basic service set (PBSS) control point (PCP) indicates which designated channels are operating and which are non-operating, for purposes of subsequent wireless communications, such as Association Beamforming Training (A-BFT). The management frame contains a bitmap or other forms for indicating which of the designated channels are operating and which are non-operating. In response to the information received through the management frame, one or more stations (STA) can select any one of the operating channels for transmitting of frames in A-BFT communication or other access periods in the Beacon Interval.

    摘要： Methods and systems for device-to-device (D2D) communication between a first device and a second device. The first device receives a communication transmitted by the second device, where the communication is intended for another recipient other than the first device. The communication provides information for the first device to determine a preferred transmit sector to be used by the second device for the D2D communication. The first device transmits a communication to the second device that provides information indentifying the preferred transmit sector to be used by the second device. As a receiver in the D2D communication, the first device receives data from the second device, transmitted on the preferred transmit sector. As a transmitter in the D2D communication, the first device transmits data to the second device on a preferred transmit sector identified in another communication received from the second device.

    摘要： Methods and devices for receiving or transmitting a wireless packet are described. A wireless packet includes a short training field (STF) and a channel estimation field (CEF). The receiver determines whether the received STF matches an assigned STF assigned for a target link, by performing cross-correlation between the STF and a component sequence from a set of at least four different component sequences which are pairs of Golay sequences. The cross-correlation output is compared with an expected output. When the received STF matches the assigned STF, the wireless packet is considered a target packet. A channel estimation is performed using a cross-correlation of the received CEF with an assigned CEF assigned for the target link. The assigned CEF is from a set of two or more CEFs, where each CEF is formed using the set of component sequences, and the CEFs are pairwise zero-correlation zone (ZCZ) sequences.
