METHOD AND APPARATUS FOR AVOIDING UNNECESSARY WIRELESS TRANSMISSIONS

Abstract

A transmitter node of a telecommunications system comprises interface circuitry and processor circuitry. The interface circuitry is configured to receive a status message over a radio interface from a receiver node regarding a packet. The processor circuitry is configured to make a determination that both (1) the status message indicates that the packet was not received from the receiver node; and (2) the packet is considered to be an obsolete packet; and, in accordance with the determination, to generate an obsolete packet indication message that identifies the packet as the obsolete packet. The interface circuitry is further configured to transmit the obsolete service data unit indication message that identifies the packet as the obsolete service data to the receiver node. Methods of operating such nodes are also provided.
