Abstract: A method and apparatus of transmitting radio link failure (RLF) information in a wireless communication system is provided. A user equipment (UE) supports a first communication system and a second communication system. The method includes detecting an RLF at a first cell of the first communication system, and reporting an RLF report message to an eNodeB (eNB) serving the first cell based on whether or not the RLF is triggered by interference from the second communication system. In addition, a method and apparatus of restricting storing and/or reporting the RLF information in a wireless communication system is provided.

Abstract: A method of moving a receiving window in a wireless mobile communication system, wherein the AM RLC of the transmitting side sends information of the last discarded SDU regardless of continuity of the discarded SDUs. The AM RLC of the receiving side checks whether all SDUs from the start point of the receiving window up to the last discarded SDU are successfully received, delivers the SDUs that are successfully received to an upper layer, and discard only those SDUs that are not successfully received.

Abstract: A method of generating a data block for performing a polling procedure in a wireless communication system, a method of transmitting data and a method of performing a polling procedure are disclosed. A protocol layer performs the polling procedure for requesting a receiving side to transmit status report if there are no data to be transmitted to the receiving side in both a transmission buffer and a retransmission buffer. When determining whether there are no data to be transmitted to the receiving side in the retransmission buffer, it is preferable that a data block for which retransmission request information is not received from the receiving side is excluded.
