  • Patent number: 10797777
    Abstract: This application relates to the field of wireless communications technologies, and provides a method for communication between terminals, a network-side device, and a terminal. The method discloses that the network-side device allocates, to the terminal, time-frequency resources for transmitting uplink information and sidelink information. On the time-frequency resources and at a same moment in a range of time domain-frequency resources, the terminal transmits the uplink information used for performing uplink beamform training to the network-side device, and transmits the sidelink information used for performing sidelink beamform training to another terminal. According to solutions provided in this application, based on conventional uplink and downlink beamform training procedures, the terminal performs the sidelink beamform training without additionally using a new time-frequency resource.

    Abstract: The present invention provides a WLAN system resource indication method and apparatus. The method includes: generating, by an access point, a frame that carries resource indication information; and sending, to multiple stations, the frame that carries the resource indication information. The resource indication information includes multiple pieces of sub resource indication information. Correspondingly, each piece of the sub resource indication information uniquely corresponds to one of the multiple stations. Therefore, a station side does not need read the entire resource indication information, so as to reduce resource overheads and improve efficiency.

  • Publication number: 20200280939
    Abstract: One embodiment of the invention describes a synchronization signal sending method applied to an unlicensed frequency band. To ensure transmission fairness, a network device performs listen before talk (LBT) before a start time for transmitting a synchronization signal, to determine whether a channel is busy or idle. When the channel is busy, the network device cannot transmit the synchronization signal at the expected start time for transmitting the synchronization signal. Therefore, the network device performs LBT again within a preset time length after the start time, and sends the synchronization signal when determining that the channel is idle by performing LBT again. When the channel is idle, the network device preempts a channel resource, and sends the synchronization signal the expected start time for transmitting the synchronization signal.

  • Publication number: 20190379508
    Abstract: Embodiments relate to the field of wireless communication technologies and provide a method for performing channel sounding, a network-side device, and a terminal. A first terminal sends a resource scheduling request to a network-side device when the first terminal starts a communication connection with a second terminal. The resource scheduling request carrying information about the second terminal requests the network-side device to allocate a transmission resource for channel sounding between the first terminal and the second terminal. The first terminal receives a sounding reference signal sent by the second terminal, and obtains information of a channel for communication between the first terminal and the second terminal. The method enables quick and effective channel sounding between terminals, thereby increasing communication efficiency between the terminals.
