Abstract

Disclosed in the present disclosure are an HARQ-ACK information transmission method and apparatus, and a communication device. The HARQ-ACK information transmission method comprises: when a one shot HARQ-ACK feedback mechanism is configured for user equipment (UE), issuing high-level signaling comprising a predetermined information domain; and on the basis of the number of transmissions N carried by the predetermined information domain, 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.

sending an activation indication in response to determine that a repeated transmission of the HARQ-ACK information is to activate, wherein the activation indication is configured to trigger the UE to send the same HARQ-ACK information for N times based on the number of transmissions; and

sending a deactivation instruction in response to determine that the repeated transmission of the HARQ-ACK information is to deactivate, wherein the deactivation instruction is configured to instruct the UE to deactivate the repeated transmission of the HARQ-ACK information.

3. The method according to claim 2 , wherein the activation indication or the deactivation indication is carried in medium access control MAC layer signaling.

4. The method according to claim 1 , wherein an X-th transmission of one piece of the HARQ-ACK information is carried by a (N+1-X)-th sub-codebook of the HARQ-ACK codebook, wherein X is a positive integer less than or equal to N.

5. The method according to claim 4 , wherein
