17. A communication device, comprising:
a transceiver;
a memory; and
a processor, respectively connected to the transceiver and the memory, for controlling the transceiver to transmit and receive a signal wirelessly by executing computer-executable instructions stored in the memory, and implementing a hybrid automatic repeat request-acknowledgement HARQ-ACK information transmission method, comprising:
sending high-level signaling comprising a predetermined information field, in response to determining that a one-shot HARQ-ACK feedback mechanism is configured for a user equipment UE; and
based on a number N of transmissions carried by the predetermined information field, receiving same HARQ-ACK information for N times on N feedback occasions corresponding to the one-shot HARQ-ACK feedback mechanism, wherein N is a positive integer,
wherein in response to an interference signal strength of a Physical Uplink Control Channel (PUCCH) being greater than or equal to an interference threshold, a value of N is a positive integer greater than or equal to 2;
in response to the interference signal strength of the PUCCH being less than the interference threshold, the value of N is a 1; and
a HARQ-ACK codebook carrying the HARQ-ACK information comprises N sub-codebooks, wherein one of the sub-codebooks carries one piece of the HARQ-ACK information.
