The invention provides a data discard signalling procedure in a wireless communication system. If data is discarded by the transmitter, the transmitter needs to notify the receiver of the discard. A shortened move receiving window super-field is used to request the receiver to move its reception window and optionally to indicate the set of discarded RLC SDUs, as a result of an RLC SDU discard in the sender. A move receiving window acknowledgement super-field acknowledges the reception of a MRW SUFI. If various criteria are met, the SDU discard with explicit signalling procedure can be efficiently terminated resulting in increased transmission throughput. Utilizing the data discard signalling procedure of the present invention, transmission throughput is increased and the transmission performance is improved. <IMAGE> |
