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