A scheduling method includes: determining whether a valid time interval is shorter than a first time interval; and when the valid time interval is smaller than the first time interval, performing a search for a time length of N predetermined search cycles. In each of the predetermined search cycles, N consecutive TD-SCDMA sub-frames are regarded as a group, and one fixed sub-frame in the group is selected for the search. In the N predetermined search cycles, the fixed sub-frames selected from the group in respective predetermined search cycles are different. N is a natural number greater than or equal to 2.
