1. A method for triggering cell reselection, comprising:
based on a Radio Resource Control (RRC) connection setup request or an RRC resume request being initiated, determining whether a number of consecutive Listen-Before-Talk (LBT) failures exceeds a preset threshold; and
based, on the number of consecutive LET failures exceeding the preset threshold, performing cell reselection, wherein said performing cell reselection comprises determining a set of target cells;
wherein said determining the set of target cells comprises:
determining a frequency priority of each candidate cell; and
determining the set of target cells based on the frequency priorities of the candidate cells;
wherein prior to said determining the frequency priority of each candidate cell, the method further comprises:
determining a first candidate cell based on a frequency where a current serving cell is located; and
decreasing the frequency priority of the first candidate cell located on the frequency by a preset level.
