Abstract: A method handling a link failure by a user equipment (UE) in a wireless communication system is disclosed. The method includes steps of suspending at least one data radio bearer (DRB) upon detecting an occurrence of the link failure; transmitting, to a specific cell, a radio resource control message indicating the occurrence of the link failure; receiving a response message as a response of the radio resource control message from the specific cell; and resuming the at least one suspended DRB.

Abstract: A method for allowing a wireless resource to be allocated in a wireless communication system, and a device therefor are disclosed. Particularly, a method by which a terminal allows a wireless resource to be allocated in a wireless communication system can comprise the steps of: receiving, from a base station, one or more pieces of semi-persistent scheduling (SPS) configuration information comprising semi-persistent resource allocation information; receiving, from the base station, an SPS activation on specific SPS configuration information among the one or more pieces of SPS configuration information; allowing a specific SPS resource to be allocated on the basis of the specific SPS configuration information; and reporting, to the base station, information indicating a transmission state of the one or more pieces of SPS configuration information when a transmission of an SPS message using the specific SPS resource is stopped.

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.

Abstract: Provided are a method for transmitting data performed by a user equipment (UE) comprising an upper layer, a switching layer and a lower layer in a wireless communication system and the UE using the same. The method includes receiving, in the switching layer, data from the upper layer, assigning a priority to the data in the switching layer, selecting a link among a plurality of links in the switching layer and transmitting, in the lower layer, the data using the selected link. Here, the link is selected based on the assigned priority of the data.

Abstract: While a user equipment (UE) performs a periodic transmission on a first link or a first carrier by using a semi-persistent scheduling (SPS) resource for the first link or the first carrier to an eNodeB (eNB), the UE may receive a SPS resource for a second link or a second carrier from the eNB. Or, a certain event may occur. Then, the UE stops using the SPS resource for the first link or the first carrier, and performs a periodic transmission on the second link or the second carrier by using the SPS resource for the second link or the second carrier to the eNB.

Abstract: A method and apparatus for performing a handover procedure in a wireless communication system is provided. A source eNodeB (eNB) of the handover procedure transmits a handover request message including a user equipment (UE) context of a master UE and a UE context of a companion UE from a source eNB. A target eNB identifies relationship between the master UE and the companion UE according to the handover request message including the UE contexts of the master UE and the companion UE.
