摘要： Methods, devices and systems for allocating spectrum in a wireless local area network. A bit representation of the availability or unavailability of a plurality of sub-bands of a portion of frequency spectrum is generated and included in a physical layer protocol data unit, which is transmitted to a target station to allocate resource units within the portion of frequency spectrum for use by the target station. The sub-bands may be 20 MHz spectrum sub-bands for large-size resource units, or the portion of frequency spectrum may be a single 20 MHz band sub-divided into multiple sub-bands for allocating small-size resource units. A station that receives the data unit may decode the bit representation and use the allocated resource units to communicate over the wireless local area network.

摘要： Methods and systems for simultaneous transmission between a transmitter and a plurality of receivers. The transmitter receives information identifying respective preferred transmission sectors for transmission from the transmitter to each receiver. The transmitter transmits a first multi-user simultaneous transmission to a first set of two or more receivers. The first set of receivers is selected for the first set by identifying that the preferred transmission sectors for transmission to the first set of receivers are included in a first virtual grouping of two or more transmission sectors. The two or more transmission sectors belonging to the first virtual grouping are defined by the transmitter.

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 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 systems for waking up an electronic device having a wake-up receiver circuit. A signal is transmitted, carrying a wake-up frame (WUF) including a protocol data unit (PDU). A wake-up sequence is inserted in a portion ahead of the PDU. The wake-up sequence is used by the electronic device for detection of the WUF and identification of the intended recipient. The WUF also includes a wake-up identifier (WUID) that is used by the electronic device to authenticate the WUF.

摘要： A method, apparatus and system for transmitting control information in a header of a physical protocol data unit (PPDU), such as an IEEE 802.11 compliant PPDU. Embodiments include indicating control features in an EDMG PPDU for Wireless LAN communications. The method and system may include overloading at least one bit of a Scrambler Initialization Field in the PPDU header (e.g. the PHY header) to convey control information, as well as to be used to initialise the scrambler shift register. The same header bits are thus used for both purposes. Examples of control information include a primary channel, channel width or MIMO configuration to be used in further communication.
