A more effective discard mechanism for Selective Repeat ARQ is achievable, where the discard mechanism exhibits a sender-initiated discard signaling scheme. The discard mechanism is also more effective where it takes into consideration the segmentation and reassembly of upper layer data packets, if such is being employed, and where it is able to notify the receiver when data units have been discarded at the sender, regardless whether explicit discard signaling from the sender to the receiver is feasible.
