  • Method, device, and system for sending and receiving control channel information
    Patent number: 9288802
    Abstract: The present invention discloses a method, device, and system for sending and receiving control channel information. When a base station schedules a first relay, the base station selects a second relay according to an optimal precoding code book selected by the first relay. An optimal precoding code book selected by the second relay is orthogonal to the optimal precoding code book selected by the first relay. Control channel information of the first relay and control channel information of the second relay his encapsulated into a high speed downlink shared control channel HS-SCCH, and scrambling the HS-SCCH. The scrambled HS-SCCH is sent to the first relay and the second relay.
