Methods and devices for partial upper layer frame loss detection based retransmission
First Claim
1. A device for detecting the partial loss of an upper layer frame, comprising:
- a detection platform adapted to determine whether a received packet is a final packet in a particular upper layer frame;
a comparator platform adapted to compare variables indicative of whether all received packets in the particular upper layer frame have been received correctly when a final packet is detected; and
a transmission platform adapted to send a signal indicative of whether a correct version of the particular upper layer frame was received.

Abstract
The present invention is aimed at techniques for detecting the “partial loss” of an upper layer frame. One technique envisions a detection platform adapted to determine whether a packet is a final packet for a particular upper layer frame. A comparator platform then compares packets received free of transmission errors with variables indicative of whether all received packets in the particular upper layer frame have been received correctly when a final packet is detected. A transmission platform then sends a signal indicative of whether the packets received without transmission errors constitute the particular upper layer frame so that lost packets can be retransmitted quickly.
