METHOD AND APPARATUS FOR ENHANCING RLC FOR FLEXIBLE RLC PDU SIZE

摘要

MMM AND APPARATUS FOR MWCING RIC FOR FLEXIBLE RIC PDU SIZE ENHANCEMENTS ARE PROVIDED FOR THE RADIO LINK CONTROL (RIC) PROTOCOL IN WIRELESS COMMUNICATION SYSTEMS WHERE VARIABLE RIC PACKET DATA UNIT (PDU) 5 SIZE IS ALLOWED. WHEN FLEXIBLE RLC PDU SIZES ARE CONFIGURED BY UPPER LAYERS, RADIO NETWORK CONTROLLER (RNC)(NODE B FLOW CONTROL, RIC FLOW CONTROL, STATUS REPORTING AND POLLING MECHANISMS ARE CONFIGURED TO USE BYTE COUNT BASED METRICS IN ORDER TO PREVENT POSSIBLE BUFFER UNDERFLOWS IN THE NODE B AND BUFFER OVERFLOWS IN THE RNC. THE ENHANCEMENTS PROPOSED HEREIN FOR THE RIC APPLY TO BOTH 10 UPLINK AND DOWNLINK COMMUNICATIONS.
