Abstract: A method and apparatus for performing a random access procedure in a wireless communication system is provided. A user equipment (UE) determines one random access configuration from a first random access configuration for a normal type of UE and a second random access configuration for a specific type of UE, and transmits a random access preamble based on the second random access configuration to an eNodeB (eNB) if the UE is a specific type of UE. Also, a method and apparatus for establishing, by a UE, a connection in a wireless communication system is provided. The UE transmits a connection request message including bandwidth related information to the eNB.

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, an Radio Resource Control (RRC) signal which configures a new Secondary Cell (SCell) with Physical Uplink Control Channel (PUCCH) resource; checking whether a Time Alignment Timer (TAT) associated with a Timing Advance Group (TAG) to which the new SCell with the PUCCH resource belong is running or not; and initiating a random access procedure on the New SCell in the TAG if the associated TAT is not running.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for notifying D2D communication, the method comprising: generating, by a first UE, a first identity (ID) according to a type of D2D (Device to Device) communication; generating, by a first UE, a first indicator indicating that the first UE is trying to perform the type of D2D communication with at least one second UE; and transmitting, by the first UE, a first MAC PDU (Medium Access Control Protocol Data Unit) including the first ID and the first indicator to that at least one second UE.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to triggering conditions for power headroom reporting (PHR) in a wireless network employing TDD scheme. According to one aspect of the present invention, the a user equipment (UE), receives information informing the UE of multiple time division duplex (TDD) uplink/downlink (UL/DL) subframe configurations and information on a threshold value for a power headroom reporting (PHR). And, the UE triggers a power headroom reporting (PHR), when a required power backoff due to a power management for any of the multiple TDD UL/DL subframe configurations has changed more than the threshold value.
