Abstract:
A method, a base station, a User Equipment (UE) and a system for sending and receiving Physical Downlink Control Channel (PDCCH) signaling are disclosed. The method for sending PDCCH signaling includes the following steps: the base station determines locations of a first search space and second search space; and the base station sends only PDCCH signaling exclusive of a Carrier Indication Field (CIF) to the UE in a physically overlapped region between the first search space and the second search space if the physically overlapped region exists and length of PDCCH signaling exclusive of a CIF in the first search space is equal to length of PDCCH signaling inclusive of a CIF in the second search space.
