1. A method for sending hybrid automatic repeat request acknowledgement information, comprising:
obtaining at least two physical uplink control channels (PUCCHs) carrying hybrid automatic repeat request acknowledgement (HARQ-ACK) information, wherein the at least two PUCCHs carrying the HARQ-ACK information overlap each other and respectively belong to different sub-slots;
multiplexing at least two pieces of HARQ-ACK information onto a target PUCCH resource of a target sub-slot in at least two different sub-slots in response to determining that the at least two PUCCHs carrying the HARQ-ACK information satisfy a timing sequence condition for multiplexing, wherein the target sub-slot is a sub-slot with the earliest start time among the at least two different sub-slots;
before multiplexing at least two pieces of HARQ-ACK information onto the target PUCCH resource of the target sub-slot in at least two different sub-slots in response to determining that the at least two PUCCHs carrying the HARQ-ACK information satisfy the timing sequence condition for multiplexing, the method further comprises:
determining a target PUCCH resource set from each PUCCH resource set corresponding to the target sub-slot according to a quantity of bits of the at least two pieces of HARQ-ACK information; and
determining the target PUCCH resource from the target PUCCH resource set according to an indication for PUCCH resources in target downlink control information (DCI), wherein the target DCI is one of DCI respectively corresponding to the at least two pieces of HARQ-ACK information, and the target DCI is DCI with an earliest sending time among the DCI respectively corresponding to the at least two pieces of HARQ-ACK information.
