sending a second signal in the target air interface resource pool, where the second signal carries the first HARQ-ACK bit block;

Sending a HARQ-ACK bit block associated with the second air interface resource pool, or giving up sending the HARQ-ACK bit block associated with the second air interface resource pool;

Wherein, the first HARQ-ACK bit block is associated with the first signal; viewed from the time domain, the second air interface resource pool is behind the first air interface resource pool; the first air interface resource pool and the second air interface resource pool are associated with the first HARQ process number, the first HARQ-ACK bit block includes HARQ-ACK information bits for the first HARQ process number; whether to send The HARQ-ACK bit block of the air interface resource pool is related to the time relationship between the target air interface resource pool and a first moment, and the first moment is associated with the second air interface resource pool.
