Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for initiating a random access procedure in a carrier aggregation system, the method comprising: receiving, from a network, a Radio Resource Control (RRC) signal which configures a Physical Uplink Control Channel (PUCCH) resource for a cell in a Timing Advance Group (TAG); checking whether a Time Alignment Timer (TAT) associated with the TAG to which the cell with PUCCH resource belong is running or not; and initiating a random access procedure if the associated TAT is not running.

Abstract: A method for a User Equipment (UE) operating in a wireless communication system. The UE configures a radio bearer comprising a first Medium Access Control (MAC) entity and a second MAC entity. The UE triggers a power headroom reporting (PHR) in the first MAC entity if a prohibitPHR-Timer of the first MAC entity expires or has expired when the first MAC entity has uplink (UL) resources for a new transmission, and a condition is satisfied. The UE transmits the PHR. The condition includes: any cell of the second MAC entity has UL transmission, and a required power backoff for the any cell of the second MAC entity has changed more than a threshold.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for configuring a new retransmission buffer status reporting timer in a D2D communication system, the method comprising: configuring that the UE belongs to both of a first group and a second group when the UE communicates with other UEs directly; configuring a first retransmission timer for the first group and a second retransmission timer for the second group; starting the first retransmission timer of the first group when a MAC Control Element for Buffer Status Reporting (BSR) is generated; and triggering a BSR when the first retransmission timer expires if data is available for the first group.

Abstract: A method and apparatus for canceling a triggered proximity-based services (ProSe) buffer status report (BSR) in a wireless communication system is provided. A user equipment (UE) triggers at least one ProSe BSR, and cancels all triggered ProSe BSR if a specific condition is met. The specific condition may be that a device-to-device (D2D) scheduling assignment for a D2D scheduling period can accommodate all pending data available for D2D transmission or that the ProSe BSR is included in a media access control (MAC) protocol data unit (PDU) to be transmitted to a network.
