Claim Text:
1. A method for detecting a Physical Downlink Control Channel (PDCCH), comprising: a User Equipment (UE) detecting a downlink control channel of the UE in a first search space and a second search space, wherein the first search space and the second search space are resources for a base station to send downlink control channel information; wherein both of the first search space and the second search space are UE-specific search spaces, and the first search space is distributed at a subframe or a time slot or a time-frequency location; and the second search space is distributed at another subframe or another time slot or another time-frequency location, wherein a time frequency at which the first search space is located and a time frequency at which the second search space is located can overlap; wherein the step of the UE detects the downlink control channel in the first search space and/or the second search space comprises: the UE using a configuration of {a, b, c, d} as the number of PDCCH candidates to detect PDCCH, wherein a, b, c and d are all positive integers and a+b+c+d is less than or equals 8; or the UE using a configuration of {e, f} as aggregation level to detect the PDCCH, where e and f are both positive integers, and the values of e and f belong to a set {1, 2, 4, 8}.
