摘要： A method is provided for managing an optimal transmission power of a Wi-Fi access point. Electronic devices are connected to the Wi-Fi access point, and the Wi-Fi access point is able to transmit with a variable transmission power. The method is executed by the Wi-Fi access point and includes the steps of determining a minimum value of a quality indicator associated with a connection of an electronic device to the Wi-Fi access point. A minimum transmission power value of the access point is determined making it possible to obtain, for the electronic device connected to the Wi-Fi access point, a value of the quality indicator associated with the connection thereof to the Wi-Fi access point higher than the minimum value. The optimal transmission power of the Wi-Fi access point is configured as being equal to the minimum transmission power determined.

摘要： A communication device generates a transmission signal for transmission via a wireless communication channel, wherein the transmission signal corresponds to a physical layer (PHY) data unit that conforms to a range extension mode of a first communication protocol. Generating the PHY data unit includes generating a preamble of a PHY data unit, wherein the preamble is generated to include: a legacy signal field that includes information indicating a duration of the PHY data unit, a duplicate of the legacy signal field, a plurality of subfields of a non-legacy signal field, and a plurality of additional subfields with the same data as the plurality of subfields of the non-legacy signal field. The plurality of subfields of the non-legacy signal field and the plurality of additional subfields are modulated to signal to a receiving device that the PHY data unit conforms to the range extension mode of a first communication protocol.

摘要： Various embodiments disclosed herein provide for facilitating uplink interference avoidance. According an embodiment, a system can comprise receiving a request to adjust an uplink power limit of a first communication device that is generating an uplink interference above a threshold and a power adjustment value employable to adjust the uplink power limit of the first communication device. The system can further facilitate identifying a packet flow in an uplink communication with the first communication device, wherein use of the packet flow results in generating of the uplink interference above the threshold. The system can further facilitate determining whether the uplink power limit of the first communication device is able to be adjusted based on a quality of service allocated to the packet flow. The system can further facilitate transmitting a message to update the uplink power limit of the first communication device using the power adjustment value.

摘要： A wireless device receives configuration parameters of: one or more first cells of a first cell type; and one or more second cells of a second cell type. A calculated total transmit power for a plurality of signals is determined. The plurality of signals comprise a first sounding reference signal (SRS) configured for transmission, during a time interval, via the one or more first cells; and a second SRS configured for transmission, during the time interval, via the one or more second cells. The wireless device drops a transmission of the first SRS or scales a transmission power of the first SRS, based on a SRS transmit power priority of the first SRS, when the calculated total transmit power exceeds a first value. The SRS transmit power priority is based on a cell type of the one or more first cells.

摘要： Systems and methods of controlling a component of a network node in a wireless communication system are presented herein. In one exemplary embodiment, a method by a network node (101, 200, 300, 560, 1400, 1721, 1741) comprises obtaining (401a) a current location (140) of a wireless device (119, 510) that is determined from measurements reported by the wireless device of a set of beam reference signals (121-126) transmitted by the network node or measurements performed by the network node of a signal (127) transmitted by the wireless device that is spatially related (129) to the corresponding beam reference signal received by the wireless device. Also, the method includes controlling (415a) a component (113-115) of the network node that enables or disables a transmission on one or more beams (121-126) of at least one beam reference signal or adjusts a transmission power of a transmission on the one or more beams of at least one beam reference signal or wireless device-specific data signal, based on a set of power trace trajectories (141-144) of the wireless device.

摘要： Methods, systems, and devices for wireless communications are described. A UE may identify a shortened transmission time interval (TTI) to be used for priority communications with a vehicle having a first traffic priority level, the shortened TTI having a duration that is less than that of other TTIs used in other communications with the vehicle having a second traffic priority level less than the first traffic priority level. The UE may transmit a request-to-send (RTS) message during the shortened TTI, the RTS message indicating an identifier and a configuration for the priority communications during the shortened TTI. The UE may receive a clear-to-send (CTS) message from one or more wireless devices participating in the priority communications, the CTS message indicating a sequence associating the CTS message with the RTS message. The UE may perform the priority communications with the wireless devices from which the CTS messages were received.

摘要： A user equipment (UE) is configured by a Master enhanced NodeB (MeNB) for operation with dual connectivity to a Secondary eNB (SeNB) to transmit acknowledgement information when the UE is power limited and for a respective eNB to determine a UE power limitation. The UE, the MeNB, and the SeNB adjust operation according to a partitioning of a UE capability between the MeNB and the SeNB. The UE capability can be a transmission power, a soft buffer size, a reception or a transmission of a number of data transport block bits, or a number of decoding operations.
