Abstract: A WLAN system resource indication method and apparatus are provided. 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.

Abstract: A data transmission method, a communication device, and a data transmission system are disclosed. The method includes: determining to-be-transmitted data that needs to be sent to a network side device; before an initial transmission moment of transmitting the to-be-transmitted data to the network side device arrives, sending the to-be-transmitted data to a coordinating device; receiving the to-be-transmitted data sent by the target device; obtaining transmission parameter information; and when the initial transmission moment corresponding to the to-be-transmitted data arrives, sending the received to-be-transmitted data to the network side device based on the transmission parameter information. Therefore, when the target device needs to send the to-be-transmitted data to the network side device, the coordinating device may help the target device perform initial transmission of the to-be-transmitted data, thereby increasing a success probability of initial transmission, and further improving link reliability.

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: Embodiments of the present invention provide a data transmission method and an apparatus. In the method, a communications node receives N spatial reuse parameters SRPs; the communications node determines, based on the received N SRPs, that the communications node can perform spatial reuse link transmission; and the communications node transmits data by using a spatial reuse link, and processes data transmission based on the spatial reuse link. Whether spatial reuse link transmission can be performed is determined based on the received SRPs, so as to reduce mutual interference between a primary link and the spatial reuse link during data transmission, and improve transmission quality.
