METHOD AND APPARATUS FOR ACCESSING UNLICENSED CHANNEL, AND DEVICE AND STORAGE MEDIUM

Abstract

Provided in the present disclosure are a method and apparatus for accessing an unlicensed channel, and a device and a storage medium, which are applied to the technical field of wireless communications. The method comprises: receiving access mode indication information and downlink control information (DCI) from a network device, wherein the access mode indication information indicates a first access mode, and the first access mode corresponds to the fact that listen before talk (LBT) does not need to be executed before a channel is occupied; on the basis of the access mode indication information and/or the DCI, determining a mode for accessing an unlicensed channel, wherein the mode for accessing the unlicensed channel is the first access mode or a second access mode, and the second access mode corresponds to the fact that LBT is executed before a channel is occupied; and accessing the unlicensed channel by using the determined mode for accessing the unlicensed channel. In the method, a user equipment receives access mode indication information and DCI; and when access modes indicated by the two are the same or different, an appropriate determination policy is used to accurately determine an access mode truly indicated by a network device, such that an unlicensed channel is correctly accessed.
