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.
