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: Embodiments of the present disclosure provide an uplink control information transmission method, a terminal device, a base station, and a system. The transmission method includes the following steps: First, the terminal device determines an information bit sequence of to-be-transmitted uplink control information. Then, the terminal device determines a first sequence according to the information bit sequence, where the first sequence is a linear-phase complex exponential sequence. Finally, the terminal device sends the to-be-transmitted uplink control information to the base station by using an uplink control channel, where the uplink control channel occupies N symbols, N is a positive integer, a signal carried on a symbol l of the N symbols is directly proportional to a product of the first sequence and a second sequence, and the second sequence is a cyclic shift sequence.
