Japanese Patent JP7319476

B2

Provided in the embodiments of the present application are a HARQ feedback method, a terminal, and a base station. The method comprises: acquiring a target timeline parameter value for indicating the timing at which a terminal feeds back a HARQ-ACK, wherein a target timeline parameter sequence is predefined between the terminal and a base station, a one-to-one correspondence between multiple sequence index values and multiple timeline parameter values is set in the target timeline parameter sequence, and the timeline parameter values indicate a timing slot interval between a feedback timing slot of the HARQ-ACK and the last symbol of a PDSCH; or the timeline parameter values indicate a timing slot where a PUCCH resource is located and the timing slot where the PUCCH resource is located corresponds to the feedback timing slot of the HARQ-ACK, the target timeline parameter value is one of the multiple timeline parameter values, and the time corresponding to the target timeline parameter value is equal to or greater than the time corresponding to a PDSCH receiving processing capability parameter value of the terminal; and on the timing slot corresponding to the target timeline parameter value, feeding the HARQ-ACK back to the base station. According to the embodiments of the present application, feedback of a HARQ-ACK is indicated when an SCS is greater than 120KHz.
