Abstract

The embodiment of the invention discloses a method and equipment for sharing channel occupation time. The method comprises the following steps: determining uplink control information UCI which comprises first indication information, and the first indication information beings used for a network device to determine related information for downlink transmission in a target time period, the network device and the terminal device sharing a target channel occupancy time (COT) in the target time period, and the target COT being obtained by the terminal device based on listen before talk (LBT); and sending the UCI. According to the method provided by the embodiment of the invention, the network equipment and the terminal equipment are consistent in understanding of downlink transmission, and thecommunication effectiveness is improved.

Description

technical field [0001] The present application relates to the field of communication technologies, and more particularly to a method and device for sharing channel occupancy time. Background technique [0002] On the unlicensed frequency band of the New Radio (NR) system, the terminal device or network device needs to perform Clear Channel Assessment (CCA) / extended Clear Channel Assessment (eCCA) before sending information. To listen to the channel, that is, to perform energy detection (Energy Detection, ED), when the energy is lower than a certain threshold, the channel is judged to be empty, and the transmission can start. Since the unlicensed frequency band is shared by multiple technologies or multiple transmission nodes, this contention-based access method leads to uncertainty in channel availability time. At present, there are mainly three types of Listen Before Talk (LBT) that can be used for NR unauthorized communication: LBT Cat 1: Send directly without any CAA, an...
