Embodiments of the present invention provide an uplink control information transmission method, user equipment, and a base station. In a first uplink demodulation reference signal UL DMRS pattern, resource elements REs in one orthogonal frequency division multiplexing OFDM symbol in an uplink subframe are used to carry the UL DMRS. The method includes: maping, by user equipment UE, uplink control information UCI to REs in the uplink subframe according to the first UL DMRS pattern, where an OFDM symbol in which the REs carrying the UCI are located is adjacent to the OFDM symbol in which the REs carrying the UL DMRS are located; and sending, by the UE to a base station, the uplink subframe that carries the UCI. Because the UCI is carried at a location adjacent to that of the UL DMRS in the uplink subframe, performance of demodulating the UCI by the base station is improved, thereby improving a data transmission rate and a network throughput. |
