Abstract
A method and an apparatus for transmitting uplink control information (UCI) are provided. The method comprises: determining a first quantity of bits of a to-be-transmitted HARQ; and transmitting the HARQ when it is determined that the first quantity of bits is less than a threshold and a sum of the first quantity of bits and a second quantity of bits is greater than the threshold. Therefore, the HARQ is directly transmitted when it is determined that the sum of the first quantity of bits and the second quantity of bits is greater than the threshold. Accordingly, a disadvantage of a low downlink throughput can be avoided.
