The invention proposes a method of and apparatus for a pre-coded physical downlink control channel reference signal and blind decoding. In a design of the reference signal, the demodulation reference signal is used for demodulating physical downlink control channel signaling, wherein the physical downlink control channel signaling is embedded in a physical downlink shared channel, an the demodulation reference signal is included in a control channel element. In a method for a user equipment to perform blind decoding, the user equipment obtains blind decoding indication information from a base station, the blind decoding indication information including an indication of a search space in which the user equipment performs the blind decoding, wherein the search space includes a control channel element of a traditional physical downlink control channel and further includes a control channel element of a pre-coded physical downlink control channel; and performs blind decoding for the number of searches indicated by the blind decoding indication information in the search space indicated by the blind decoding indication information, according to the blind decoding indication information. |
