Abstract: In the present invention, service data units (SDUs) are delivered from a first layer to a second layer out-of-order irrespective of sequence numbers (SNs) of the SDUs. The second layer deciphers the SDUs in the order of reception from the first layer irrespective of the SNs. The second layer may reorders the deciphered SDUs in the order of the SNs, and delivers them to an upper layer in sequence.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for reporting an RLC (Radio Link Control) re-transmission failure in the wireless communication system, the method comprising: communicating with both the first BS and the second BS, wherein the first BS has a Radio Resource Control (RRC) connection with the UE; and reporting to the first BS, a Radio Link Control (RLC) retransmission error without RRC connection re-establishment for the first BS if the RLC retransmission error occurs in an RLC entity transmitting RLC PDU (Protocol Data Unit) to the second BS.

Abstract: A method for transmitting data through a logical channel by a user equipment (UE) in a wireless communication system is disclosed. The method comprises determining whether data for the logical channel exists or not; increasing a token value based on a prioritized Bit Rate (PBR) and a time elapsed since the data becomes available for the logical channel, when the data for the logical channel exists; and transmitting the data or a part of the data through the logical channel, when the token value is greater than 0, wherein when there is no data for the logical channel, the token value is not increased.
