Original Abstract Submitted
A method for hybrid automatic repeat request feedback includes: determining an initial slot where a HARQ-ACK transmission is located; determining that a PUCCH resource on the initial slot is invalid, determining a valid second PUCCH resource, and sending the HARQ-ACK through the second PUCCH resource, in which, a slot where the second PUCCH resource is located is a slot after the initial slot and no later than a last delay feedback slot for the HARQ-ACK. The last delay feedback slot is determined based on the initial slot and a maximum delay feedback slot offset value, or the last delay feedback slot is determined from more than one candidate last delay feedback slot, or the last delay feedback slot is determined based on a TDRA table; or the last delay feedback slot corresponds to the first PUCCH resource.
