Abstract: A terminal device determines a resource of a physical uplink control channel. The physical uplink control channel carries a first encoded bit sequence and a second encoded bit sequence, the first encoded bit sequence is corresponding to first uplink control information, and the second encoded bit sequence is corresponding to second uplink control information. The resource for the physical uplink control channel includes N orthogonal frequency division multiplexing (OFDM) symbol sets. The first encoded bit sequence is carried in an OFDM symbol included in j OFDM symbol sets, the j OFDM symbol sets are a part of or all of of the N OFDM symbol sets, where j is a positive integer less than or equal to N. The terminal device sends, on the resource for the physical uplink control channel, a signal that is generated based on the first uplink control information and the second uplink control information.

Abstract: In the field of wireless communication, a method and an apparatus for transmitting Uplink Control Information (UCI) are provided. The method includes: determining a codeword corresponding to the UCI among multiple codewords according to a preset rule when the UCI is transmitted on a Physical Uplink Shared Channel (PUSCH) with the multiple codewords (101); and transmitting the UCI by mapping the UCI onto the corresponding codeword (102). The apparatus includes a determining unit and a transmitting unit. The method and the apparatus provide a solution to transmitting UCI on a PUSCH with multiple codewords. This solution can be implemented easily based on LTE R8, without involving too much additional work of standardization.

Abstract: Embodiments provide a channel sounding information feedback method, user equipment, and a base station. The method includes: determining, by UE, a first period used to periodically report channel sounding information; and periodically sending, by the UE based on received preset downlink control information DCI that is sent by a base station, the channel sounding information by using the first period as a sending period. System overheads can be reduced, a configuration response can be improved, and spectrum utilization of a system can be improved while periodic feedback of indication is reduced.

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.
