Abstract  Abstract

PROBLEM TO BE SOLVED: To provide a medium access control (MAC) architecture which allows the scheduling entity to initiate new transmissions at any time and to reinitiate previously unsuccessful transmissions at any time.

SOLUTION: A MAC architecture determines transmission latency and block error rate requirements for a plurality of data flows each data flow having an associated priority and each data flow comprising a plurality of data blocks. The MAC architecture specifies a scheduling entity (53) that determines when transmissions are serviced and by which hybrid automatic repeat request (H-ARQ) entity. H-ARQ entities (52a 52b) determine whether each prior block had been successfully transmitted and if not request retransmission of unsuccessfully transmitted data blocks. The scheduling of the data blocks takes into account whether or not the previously transmitted data blocks require retransmission.
