Channel access method and device, storage medium, terminal, and base station

A channel access method, comprising:

• receiving configuration information, wherein the configuration information comprises configuration information of at least one available bandwidth that is configured to perform an LBT operation, and the at least one available bandwidth is a portion of bandwidth of a carrier;
• performing the LBT operation on the at least one available bandwidth indicated by the configuration information to listen to a channel;
• and
• when the LBT operation on any one of the at least one available bandwidth succeeds, performing uplink data transmission on the available bandwidth to access the channel,
• wherein each of the at least one available bandwidth is associated with at least one listen direction that is determined based on spatial configuration of a reference signal resource, and performing the LBT operation on the at least one available bandwidth indicated by the configuration information comprises:
• for each of the at least one available bandwidth, performing the LBT operation in each listen direction associated with the available bandwidth.
