HARQ process identifier based on a HARQ process identifier offset
A base station transmits a radio resource control message. The radio resource control message comprises uplink periodic resource allocation configuration parameters indicating: a hybrid automatic repeat request (HARQ) process identifier offset; and a number of uplink periodic resource allocation HARQ processes. A HARQ process identifier for a current transmission time is determined as a sum of the HARQ process identifier offset and a value determined based on the number of uplink periodic resource allocation HARQ processes. A transport block associated with a HARQ process identified by the HARQ process identifier is received.
