Abstract: The present disclosure relates to the field of WLAN technologies, and discloses a target wake time-based communication method, an apparatus, and a system, which may be applied to a wireless communication system that supports the 802.11be standard. According to the method, an AP indicates a candidate traffic identifier corresponding to allowed to be transmitted within a restricted TWT SP. When requesting to join a restricted TWT, a STA selects one or more traffic identifiers from the candidate traffic identifier indicated by the AP. Traffic corresponding to the traffic identifier selected by the STA requested by the STA to transmit within the restricted TWT SP. After receiving a request of the STA for joining the restricted TWT, the AP may allow the STA to join the restricted TWT, to transmit, within the restricted TWT SP, the traffic corresponding to the traffic identifier selected by the STA.
