Claim:
1. A method for receiving a control channel, the control channel being demodulated by using a UE-specific reference signal (UERS), the method comprising: obtaining, by user equipment (UE), time-frequency resource information of the control channel and location information of a search space; determining, by the UE, the search space according to the time-frequency resource information and the location information, wherein a time-frequency resource corresponding to the time-frequency resource information includes the search space, the time-frequency resource includes one or more resource block (RB) pairs, each RB pair corresponding to the search space is capable of carrying two or more candidate control channels at an aggregation level, and for one antenna port number, each RB pair corresponding to the search space includes all or a part of at most one candidate control channel at the aggregation level, for K RB pairs in all RB pairs corresponding to the search space, each of the K RB pairs includes all or a part of one candidate control channel at the aggregation level, K is equal to 1 or is larger than 1, the one candidate control channel corresponds to configuration information of one UERS, and the configuration information of one UERS includes the one antenna port number; and receiving, by the UE, the control channel and the UERS in the search space.
