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: 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.
