    摘要： A network performance improvement method and an apparatus for user equipment. In the network performance improvement method, user equipment establishes a first PDN connection and transmits data of a first application program through the first PDN connection. Then, the user equipment starts a second application program and determines whether a current network status satisfies a quality of service requirement of the second application program. When determining that the current network status does not satisfy the quality of service requirement of the second application program, the user equipment starts to establish a second PDN connection, and transmits, after the second PDN connection is successfully established, at least a part of application data of the second application program through the second PDN connection.

    摘要： Traditionally in RU or RRH (Remote Radio Head) designs either frequency-synchronization or time-synchronization is present in the measuring wireless equipment. In such radios it is not possible to directly time-synchronize the measuring instruments to decode the constellation and downlink data channels of RU/RRH due to lack of timing synchronization signal. There are no system and method to directly time-synchronize the measuring instruments to decode the constellation and downlink data channels of RU/RRH due to lack of timing synchronization signal. The disclosure proposes system and method for deriving a timing synchronization signal for e.g., a 10 Mhz external frequency output provided by the RU and thereby time-synchronizing the measuring equipment to the RF signal transmitted by the RU, thus opening up a spectrum of various possibilities to use the equipment to monitor and diagnosis of an indoor-cellular system in deployment.

    摘要： A communication method, a terminal device, and a network device are disclosed. The communication method includes: A first terminal device receives second configuration information, where the second configuration information is used to obtain first information used for direct communication between the first terminal device and a second terminal device, and the first information includes at least one of the following: a service sending latency, a service sending throughput, a service receiving throughput, a sent service data amount, a received service data amount, a service data packet loss rate, or control information between the first terminal device and the second terminal device; the first terminal device obtains the first information; and the first terminal device sends the first information to a network device. The foregoing method increases an amount of information obtained from a direct communication system.

    摘要： Embodiments of a backscatter communication system and methods of using the system are disclosed. The system may comprise a first short-range wireless communication (SRWC) device, a second SRWC device, and a backscatter node. The first SRWC may comprise a processor and memory storing a plurality of instructions executable by the processor, the plurality of instructions comprising, to: determine a first and second sets of link parameters for a radio frequency (RF) signal; determine a selected set of link parameters for backscatter communication, wherein the selected set of link parameters is one of the first or second sets of link parameters; share the selected set of link parameters with a second SRWC device; and following backscatter communication using the selected set of link parameters via the RF signal, iteratively update the first and second sets of link parameters and correspondingly iteratively re-determine, share, and update the selected set of link parameters.

    摘要： A wireless device receives configuration parameters of cells grouped into physical uplink control channel (PUCCH) groups. The cells are in the same timing advance group. A first sounding reference signal (SRS) is transmitted via a first cell of a first PUCCH group in parallel with transmission of a first PUCCH via a second cell of a second PUCCH group. In response to a second PUCCH being transmitted via the first cell in parallel with a configured transmission of a second SRS, the configured transmission of the second SRS via the first cell is dropped.

    摘要： According to certain embodiments, a method by a network node (860) for shifting cell borders of multiple frequency bands includes deploying at least two frequency bands. Each of the at least two frequency bands have at least two cells, and each cell have an associated cell coverage area within a common target coverage area. Each of the at least two frequency bands are associated with a respective interference area along a respective cell border, and each interference area is characterized by interference from an adjacent cell. The associated cell coverage area of at least one of the at least two frequency bands is adjusted such that the respective cell border of the at least one of the at least two frequency bands is shifted to reduce a common interference area of the at least two frequency bands. The common interference area is an area where the respective cell borders of the at least two frequency bands overlap.
