METHOD AND AN APPARATUS FOR HANDLING CONTROL PDUS WHEN A TRANSMITTING SIDE IS ESTABLISHED IN A WIRELESS COMMUNICATION SYSTEM, ESPECIALLY CONCERNED WITH HANDLING CONTROL PDUS WHEN ONLY THE TRANSMITTING SIDE OF AN RLC ENTITY IS ESTABLISHED

摘要

A wireless communications system has a communications device (100), which has an RLC entity (206) having a transmitting side and a receiving side. When re-establishing the transmitting side, to handle control PDUs, only the transmitting side in the RLC entity of the communications device is re-established, a first control PDU corresponding to the transmitting side is discarded, and a second control PDU corresponding to the receiving side is retained and not discarded.
