METHOD AND APPARATUS FOR ENHANCING RLC FOR FLEXIBLE RLC PDU SIZE

摘要

Enhancements are provided for the radio link control (RLC) protocol in wi reless communication systems where variable RLC packet data unit (PDU) size is allowed. When flexible RLC PDU sizes are configured by upper layers, radi o network controller (RNC)/Node B flow control, RLC flow control, status rep orting and polling mechanisms are configured to use byte count based metrics in order to prevent possible buffer underflows in the Node B and buffer ove rflows in the RNC. The enhancements proposed herein for the RLC apply to bot h uplink and downlink communications.
