1. A method for transmitting hybrid automatic repeat request acknowledgement (HARQ-ACK) information, comprising:
receiving first downlink control information (DCI), wherein a slot offset information field of the first DCI has a first value;
receiving second DCI, wherein a slot offset information field of the second DCI has a second value different from the first value; and
sending HARQ-ACK information of a physical downlink shared channel (PDSCH) transmission scheduled by the first DCI based on the second DCI, in response to determining that a value of a downlink assignment index (DAI) field comprised in the second DCI and a value of a DAI field comprised in the first DCI meet a predetermined condition;
wherein, the value of the DAI field comprised in the first DCI is M1, and the value of the DAI field comprised in the second DCI is M2, where both M1 and M2 are natural numbers,
determining that the value of the DAI field comprised in the second DCI and the value of the DAI field comprised in the first DCI meet the predetermined condition comprises:
determining that the value of the DAI field comprised in the second DCI and the value of the DAI field comprised in the first DCI meet the predetermined condition in response to M2=(M1+1) mod N, where N is a number of values that can be indicated by the DAI field.
