Abstract: A method is provided, including: determining, a first receiving state corresponding to a first data channel and a second receiving state corresponding to a second data channel; generating, a hybrid automatic repeat request-acknowledgement HARQ-ACK feedback message, where the HARQ-ACK feedback message is at least used to indicate the first receiving state and the second receiving state, a first time length of a time domain resource occupied by the first data channel is less than a second time length of a time domain resource occupied by the second data channel; and sending, the HARQ-ACK feedback message on a time domain resource having a third time length. By using the foregoing solution, the terminal device can efficiently feed back, receiving states corresponding to a plurality of data channels or a plurality of pieces of data transmission that occupy time domain resources of different lengths, thereby ensuring communication service quality.

Abstract: Devices and methods are provided for receiving a first indication and a second indication, the first indication associated with a first set of transmission parameter information for a first repetition of data received in a Physical Downlink Shared Channel (PDSCH) and the second indication associated with a second set of transmission parameter information for a second repetition of data received in the PDSCH. Each set of transmission parameter information corresponds to a Quasi-Co-Location (QCL) information for the respective repetition of data. In addition, the method involves receiving a first PDSCH repetition and a second PDSCH repetition. A channel estimate can then be performed for the first PDSCH repetition based on the QCL information for the first PDSCH repetition and a channel estimate for the second PDSCH repetition based on the QCL information for the second PDSCH repetition.

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.
