Abstract: The application discloses a wireless communication method that includes receiving, by a network device, uplink transmission of a first terminal in a first duration of channel occupancy duration of the first terminal. The channel occupancy duration of the first terminal further includes a second duration, and the second duration is later than the first duration. The network device performs downlink transmission in the second duration, where the sum of the first duration and the second duration is less than or equal to the channel occupancy duration of the first terminal. The method provides an efficient use of resources obtained through contention in an unlicensed frequency band.

Abstract: Embodiments of the present invention provide a method which includes: sending a first channel quality measurement report, wherein the first channel quality measurement report indicates a channel noise value measured in a first time period by a first station in a second antenna mode when a third station and a fourth station communicate with each other in a first antenna mode; and receiving an grant frame sent by the AP based on the first channel quality measurement report, wherein the grant frame carries first instruction information and/or second instruction information. A success rate of space-shared communication between station pairs can be increased.

Abstract: This application provides an indication method, a network device, and user equipment. The network device explicitly or implicitly indicates, by using indication information (including but not limited to a bitmap, information indicating a quantity Wt, and information indicating an index) carried on one or more downlink transmission units, a reception response for one or more downlink transmission unit sets that needs to be received by the network device, that is, a reception response for one or more downlink transmission unit sets that needs to be sent by the UE to the network device, so that the UE can correctly send, on a correct uplink transmission unit, the reception response that is for the downlink transmission unit sets and that the network device indicates the UE to send. In this way, errors and unnecessary retransmission are reduced, quality of service is ensured, and communication efficiency is improved.
