Abstract:
The present invention discloses a method and an apparatus for sending rank indication (RI) information, and a method and an apparatus for receiving RI information, wherein the method for sending the RI information includes: carrying the RI information on a physical uplink control channel (PUCCH) for transmitting scheduling request (SR) information when the RI information and the SR information are sent within a same subframe, and sending the RI information and the SR information by using the PUCCH for transmitting SR information. According to the present invention, the problem that the orthogonality of codes between PUCCHs is destroyed due to that the RI information and the SR information are sent within a same subframe is solved, the overall system performance thereby can be guaranteed.
