Patent ID: 8774224

Claim:
A method of transmitting uplink control information of a user equipment in a physical uplink shared channel (PUSCH) over which uplink control information and data can be transmitted in an uplink subframe comprising the PUSCH and a physical uplink control channel (PUCCH) over which only uplink control information can be transmitted, the method comprising: generating data; generating uplink control information repeatedly as many times as a number of uplink data transmission layers of the data; multiplexing the data and the repeatedly generated uplink control information in the PUSCH; and transmitting the data and the repeatedly generated uplink control information in the uplink subframe, wherein the uplink subframe comprises a plurality of single carrier-frequency division multiple access (SC-FDMA) symbols in a time domain and a reference signal is allocated to two SC-FDMA symbols among the plurality of SC-FDMA symbols in the PUSCH, and wherein when the repeatedly generated uplink control information comprises an ACK/NACK (acknowledgement/not-acknowledgement) and an RI (rank indicator), the ACK/NACK is allocated to SC-FDMA symbols which are adjacent to the two SC-FDMA symbols to which the reference signal is allocated and the RI is allocated to SC-FDMA symbols which are adjacent to the SC-FDMA symbols where the ACK/NACK is allocated.
