Abstract: This application discloses a wireless communication method, including: receiving, by a network device, uplink transmission of a first terminal in first duration of channel occupancy duration of the first terminal, where the channel occupancy duration of the first terminal further includes second duration, and the second duration is later than the first duration; and performing, by the network device, downlink transmission in the second duration, where a sum of the first duration and the second duration is less than or equal to the channel occupancy duration of the first terminal. This application further discloses a network device and a terminal that correspond to the wireless communication method. By applying the method and devices, a resource obtained through contention by a terminal applied to an unlicensed frequency band can be properly used, to improve operating efficiency of the unlicensed frequency band.

Abstract: This application discloses a communication method. The method includes: comparing, by a second transmit end device, a second bandwidth carrying at least one second service transmission and a first bandwidth, wherein the first bandwidth is used by a first transmit end device within a first specified time period on an unlicensed frequency band to complete first service transmission, the at least one second service transmission started in a remaining time period of the first specified time period after the first service transmission is completed; performing channel listening on the second bandwidth based on a result of the comparison; and performing, by the second transmit end device, the second service transmission on the second bandwidth if the second bandwidth is found to be in an idle state. In addition, a corresponding transmit end device is disclosed. This application discloses a channel listening mechanism applicable to a flexible-bandwidth scenario.
