RoHC OPTIMIZATIONS FOR BURST LOSSES

摘要

Systems and methods are disclosed for optimizing Robust Header Compression (RoHC) to protect against context desynchronization resulting from a burst of lost packets. In one embodiment, a method of operation of a radio node to adapt a RoHC compressor of a radio node based on a transmit channel quality metric is provided. In another embodiment, systems and methods relating to improved RoHC SN decoding are disclosed. In one embodiment, a method of operation of a radio node includes determining a size of a Packet Data Convergence Protocol (PDCP) Sequence Number (SN) gap for a radio link between the radio node and a second radio node, and performing RoHC SN decoding based on the size of the PDCP SN gap.

1. A method of operation of a radio node, comprising:
computing a value for a transmit channel quality metric based on channel quality information for a transmit channel between the radio node and a second radio node; and adapting a Robust Header Compression, RoHC, compressor for a link between the radio node and the second radio node based on the value for the transmit channel quality metric.
