Patent ID: 8553671

Claim:
A method for transmitting uplink control information (UCI), performed by a user equipment, in a wireless communication system, the method comprising: generating a spread sequence by block-wise spreading of modulation symbol sequences with an orthogonal sequence; and transmitting the spread sequence to a base station through an uplink control channel in a subframe, wherein the modulation symbol sequences are generated by modulating encoded information bits and the encoded information bits are generated by performing channel coding on information bits of the UCI, wherein when the subframe is configured for transmission of a scheduling request (SR) and when transmission of a hybrid automatic repeat request(HARQ)-acknowledgement(ACK) coincides with the subframe, the information bits of the UCI comprise concatenation of HARQ-ACK information bits for each of serving cells and a SR information bit, wherein the SR information bit is appended to the end of the concatenated HARQ-ACK information bits, and wherein transmission power of the uplink control channel is determined based on a bit number of the HARQ-ACK information bits and a value determined by whether or not the subframe is configured for a scheduling request.
