摘要： A method and system for time synchronization in a mobile device are disclosed. The method includes negotiating a synchronization schedule. The synchronization schedule defines a plurality of synchronization times for receiving synchronization messages. The method further includes transitioning the mobile device from a first state to a second state to receive a synchronization message. The mobile device uses less power in the first state than the second state and the mobile device cannot receive the synchronization message when in the first state. The method further includes synchronizing a clock component in response to receiving the synchronization message.

摘要： A method and devices are provided for adapting the transmission power level of a mobile terminal during a handover phase at which the mobile terminal switches from one base station to another. The method provided comprises applying values of operating parameters that characterize both base stations and adapting the transmission power level to an acceptable level at which communications transmitted from the terminal to the second station would be properly received without applying further increase in the transmission power while ensuring that the communications transmitted by the mobile terminal to the second base station, will not cause severe interference to communications exchanged between the second base station and the other terminals communicating therewith.

摘要： There is provided a method and devices for dynamically controlling transmission of communications in a wireless network, which comprises a managing entity and a managed entity that communicate which each other. The managed entity transmits updating information that includes indications of current resources available thereat and/or indications that relate to the reception of communications transmitted by the managing entity. A reporting rate for transmitting the updating information by the managed entity to the managing entity is then determined, and based on the reporting rate that has been determined—modifying, if required, parameters associated with the wireless link extending between the two entities so as to affect changes in the operating conditions at one or both of these entities.

摘要： Embodiments of an access point (AP), station (STA) and method for multi-user (MU) location measurement are generally described herein. The AP may contend for a transmission opportunity (TXOP) to obtain access to a channel. The AP may transmit a trigger frame (TF) to initiate a multi-user (MU) location measurement during the TXOP. The AP may receive service requests for the MU location measurement from a plurality of STAs. The AP may transmit an MU acknowledgement (ACK) frame that indicates reception of the service requests. The AP may receive, from the STAs, uplink sounding frames that include per-STA timing information for the service requests and the MU ACK frame. The STA may determine location measurements for the STAs based on the per-STA timing information included in the uplink sounding frames.

摘要： Embodiments of an access point (AP), station (STA) and method for uplink sounding are generally described herein. The AP may transmit an uplink (UL) sounding trigger frame (TF) that indicates a request to receive UL sounding elements from a group of one or more stations (STAs). The AP may receive UL sounding elements from the STAs in accordance with UL multi-user multiple-input multiple-output (MU-MIMO) reception. The AP may also receive, from at least a portion of the STAs, UL sounding feedback that includes one or more UL sounding transmission parameters used by the portion of the STAs for UL sounding element transmissions. The UL sounding TF may further indicate the portion of the STAs that are to transmit the UL sounding feedback.

摘要： Apparatuses, methods, and computer readable media are disclosed for fragmentation of media access control service data units (MSDU) in a high-efficiency wireless local-area network. An apparatus of a access point or station comprising memory and processing circuitry coupled to the memory is disclosed. The processing circuitry is configured to fragment a media access control (MAC) service data unit (MSDU) into two or more MSDU fragments, and encapsulate the two or more MSDU fragments into two or more aggregated MSDUs (A-MSDUs); one or more A-MSDUs and one or more MAC protocol data units (MPDUs); or, two or more MPDUs. The processing circuitry may be further configured to encode a delimiter in front of a first fragment of the two or more MSDU fragments, where the delimiter indicates a length of the two or more MSDU fragments, and to encode each MPDU to comprise a sequence number.
