Abstract  Abstract

PURPOSE: An improved MAC-architecture both in the UTRAN(UMTS Terrestrial Radio Access Network) and UE is provided to allow higher priority transmissions to supercede lower priority transmissions and the ability to reinitiate transmissions at any time. CONSTITUTION: In the device, the scheduling entity(53) ensures proper prioritization of transmissions according to data flow QoS latency requirements and allows for reinitiation of failed H-ARQ transmissions that permits the greater ability to achieve QoS Block Error Rate(BLER) requirements. These abilities of the scheduling entity(53) are not possible when H-ARQ processing precedes the scheduling function. The scheduling entity(53) manages HS-DSCH physical resources between the H-ARQ entities(52a,52b) and data flows according to their QoS requirements for transmission latency and transport channel BLER requirements. Beside the QoS parameters, the scheduling algorithm used by the scheduling entity(53) also operate according to, for example, various radio control resource parameters such as the signal-to-interference ratio(SIR), available and rate, speed of the UE, current load of the cell and other factors that are well known to those of skill in the art. The scheduling entity(53) determines the data (associated with a particular UE), and the H-ARQ entities(52a,52b) that service the transmission.
