Abstract:
1. A method for sending Physical Downlink Control Channel (PDCCH) signaling to a user equipment (UE), comprising: determining locations of a first search space and a second search space, wherein the first search space and the second search space each comprises a plurality of control channel elements (CCEs), and the PDCCH signaling is made up of one or more CCEs; determining whether the first search space and the second search space overlap in one or more CCEs; and if the first search space and the second search space overlap in one or more CCEs and if a length of the PDCCH signaling not including a carrier indication field (CIF) in the first search space is equal to a length of the PDCCH signaling including the CIF in the second search space, sending, in the one or more overlapped CCEs, the PDCCH signaling with no CIF to the UE.
