Abstract: A method, an apparatus, and a system for transmitting information bits, where the method for transmitting information bits includes: dividing the information bits to be transmitted into at least two groups; encoding the information bits to be transmitted in each group; modulating the coded bits obtained by the encoding to obtain modulation symbols, in which each modulation symbol is obtained by using the modulation of the coded bits in the same group; and mapping and transmitting the modulation symbols. In this way, the receiving end easily reduces the algorithm complexity, thereby ensuring the performance of the receiving end.

Abstract: 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.
