The present invention discloses a method, device, and system for sending and receiving control channel information, belonging to the field of communication technologies. The method includes: when a base station schedules a first relay, selecting, by the base station, a second relay according to an optimal precoding code book selected by the first relay, where an optimal precoding code book selected by the second relay is orthogonal to the optimal precoding code book selected by the first relay; encapsulating control channel information of the first relay and control channel information of the second relay into a high speed downlink shared control channel HS-SCCH, and scrambling the HS-SCCH; and sending the scrambled HS-SCCH to the first relay and the second relay. According to the present invention, when the base station performs MU-MIMO transmission for two relays, one HS-SCCH serves two MU-MIMO relays, which reduces occupation of limited HS-SCCHs. As compared with the mode in which either of two MU-MIMO relays uses one HS-SCCH, a waste of data code channels caused by limited HS-SCCHs is well reduced, and therefore system throughput is improved. |
