摘要： A method for transmitting and receiving Uplink Control Information (UCI), a terminal, and a base station are provided. The transmitting method includes: calculating the number (Q′) of modulation symbols occupied by the UCI to be transmitted; dividing the information bit sequence of the UCI to be transmitted into two parts; using Reed Muller (RM) (32, 0) codes to encode each part of information bit sequence of the UCI to be transmitted to obtain a 32-bit coded bit sequence respectively, and performing rate matching so that the rate of the first 32-bit coded bit sequence is ┌Q′/2┐×Qm bits and that the rate of the second 32-bit coded bit sequence is (Q′−┌Q′/2┐)×Qm bits; and mapping the two parts of coded bit sequences that have undergone rate matching onto a Public Uplink Shared Channel (PUSCH), and transmitting the coded bit sequences to a base station.
