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: This application discloses a method for a hybrid automatic repeat request (HARQ) feedback of downlink data. A terminal receives downlink data of a physical downlink shared channel (PDSCH) and downlink data of a physical downlink control channel (PDCCH) or an enhanced physical downlink control channel (EPDCCH) from a base station. Then the terminal sends a hybrid automatic repeat request (HARQ) feedback codebook to the base station. A size of the HARQ feedback codebook is based on a state of a semi-persistent scheduling (SPS) PDSCH transmission and a total downlink assignment indicator in the downlink data of the PDCCH or the EPDCCH, and the HARQ feedback codebook comprises a HARQ bit for the SPS PDSCH transmission.

Abstract: Embodiments of the present disclosure provide a method for a transmission of uplink control information (UCI), such as hybrid automatic repeat request (HARQ) information. A base station sends first indication information to a user equipment (UE), to instruct the UE to dynamically determine the UCI according to the first indication information, and the base station allocates a physical uplink control channel (PUCCH) resource to the UE to transmit the UCI. The embodiments of the present disclosure may be used to implement a feedback of the UCI information in a carrier aggregation scenario, thereby improving performance of transmitting valid UCI information.
