1. A method for transmitting control information, comprising:
receiving, by a terminal device, a first downlink signal, Hybrid Automatic Repeat Request-Acknowledgement (HARQ-ACK) information corresponding to the first downlink signal being transmitted through a first Physical Uplink Control Channel (PUCCH);
receiving, by the terminal device, a second downlink signal, HARQ-ACK information corresponding to the second downlink signal being transmitted through a second PUCCH, wherein the second PUCCH and the first PUCCH correspond to a same HARQ-ACK codebook; and
canceling, by the terminal device, transmission of the first PUCCH, and transmitting the second PUCCH, the second PUCCH carrying a first HARQ-ACK codebook, and the first HARQ-ACK codebook at least comprising the HARQ-ACK information corresponding to the second downlink signal;
wherein in a case that the first HARQ-ACK codebook is a type-2 HARQ-ACK codebook, a correspondence between a bit in the first HARQ-ACK codebook and a downlink signal is determined based on a first target Downlink Allocation Index (DAI) of the downlink signal, wherein
the first target DAI is a DAI of the downlink signal, wherein the DAI of the downlink signal is counted from a starting downlink signal after the first downlink signal in a plurality of downlink signals corresponding to the first HARQ-ACK codebook; or,
the first target DAI is obtained by subtracting the DAI of the first downlink signal from the DAI of the downlink signal, wherein the DAI of the downlink signal is counted from the starting downlink signal in the plurality of downlink signals corresponding to the first HARQ-ACK codebook.
