In the field of radio communication technologies, 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 ”Œ Q' /2”�× Q m bits and that the rate of the second 32-bit coded bit sequence is ( Q' -”Œ Q' /2”�)× Q m 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. Further, a receiving method, a terminal and a base station corresponding to the transmitting method are disclosed. Through the foregoing technical solution, the UCI can be transmitted properly even if the number of bits occupied by the UCI is greater than the maximum number of bits supported by RM(32, O) code, each part of information bit sequence of the UCI obtains enough coding gain even if the ( Q' -/2”�)× Q m is greater than 24 bits, thereby improving transmission performance of the UCI. |
