Abstract: The present invention relates to a method for performing retransmissions by a transmission end in a wireless communication system. In particular, the method includes the steps of: re-transmitting a data unit to a reception end; and increasing a retransmission counter associated with the data unit, when the retransmission counter associated with the data unit reaches to a max value, reporting a max retransmission indication to an upper layer and setting the retransmission counter associated with the data unit to zero.

Abstract: A method for a wireless device operating in a wireless communication system includes receiving configuration information for configuring a non-Physical Uplink Control Channel (PUCCH) cell; and transmitting a Hybrid Automatic Repeat request (HARQ) feedback of the non-PUCCH cell on a special cell (SpCell) or a PUCCH cell other than SpCell, according to indication information. Further, when the indication information is not received with the configuration information, the HARQ feedback is transmitted on the SpCell, and when the indication information is received with the configuration information, the HARQ feedback is transmitted on the PUCCH cell.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for triggering a sidelink buffer status reporting in a D2D communication system, the method comprising: configuring a first ProSe destination including at least one first UE and a second ProSe destination including at least one second UE; receiving a first sidelink data for a first sidelink logical channel from an upper layer; receiving a second sidelink data for a second sidelink logical channel from the upper layer while the UE has the first sidelink data for the first logical channel, wherein the second logical channel has a higher priority than a priority of the first sidelink logical channel; and triggering a buffer status reporting the if the first sidelink logical channel and the second sidelink logical channel belong to a same ProSe destination.

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: The present invention relates to a communication between MAC layer entity and PHY layer entity for parallel random access procedures of dual connectivity. In this scheme, a first PHY entity of a user equipment informs a failure of a random access preamble transmission to a first MAC entity of the UE. Then, the first MAC entity continues or stops a random access procedure without performing procedures for a random access failure.
