Abstract: The present disclosure provides a method and an apparatus for transmitting control data. The method includes: determining, by a terminal device, at least one target cell from at least one unlicensed cell; and transmitting, by the terminal device, control data in the target cell. This can implement transmission of the control data on an unlicensed spectrum resource, so that the control data can be transmitted not merely on a licensed spectrum resource, and communication reliability and user experience can be improved. In addition, this can reduce licensed spectrum resource overheads in a communication process, and increase a capacity of a communications system that has a limited quantity of licensed spectrum resources.

Abstract: Embodiments of the present invention provide a method, where a UE determines that uplink control information to be sent to an eNB in an uplink subframe includes channel state information (CSI) and a scheduling request (SR). The UE further determines a first uplink channel resource for sending the CSI and the SR to the eNB. The first uplink channel resource has an SR sending format and is used to send the CSI. The UE then sends the CSI and the SR to the eNB on the first uplink channel resource in the uplink subframe.
