Abstract: A method and apparatus for changing a physical cell identity (PCI) of a mobile relay node (MRN) cell in a wireless communication system is provided. When a donor eNodeB (DeNB) changes the PCI of the MRN cell, the DeNB transmits a message indicating a change of the PCI of the MRN cell to an MRN if it is determined that the PCI of the MRN cell collides with the PCI of a DeNB cell or a PCI of neighbor cells. When the MRN changes the PCI of the MRN cell, the MRN transmits a message including the changed PCI of the MRN cell to user equipments (UEs) served by the MRN.

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.
