Abstract: A method for performing random access in a wireless communication system is provided. The method includes transmitting a preamble for random access in uplink, receiving a random access response message including back-off information as a response to the preamble, and performing back-off using the back-off information when the random access has failed.

Abstract: A method for communicating between a user equipment (UE) and a network in a wireless communication system, the method includes receiving, by the UE, a first multimedia broadcast multimedia service (MBMS) service from a first cell on a first frequency while the UE is in an idle mode; receiving, by the UE, a first system information block (SIB) from the first cell on the first frequency, the first SIB including information on an MBMS service area (SA) provided at a second frequency; receiving, by the UE, a second SIB from a second cell on the second frequency, the second SIB including information on a multimedia broadcast multicast single frequency network (MBSFN) area; and receiving, by the UE, a second MBMS service from the second cell on the second frequency, based on the received information on the MBSFN area.

Abstract: A method for random access to a base station by a user equipment (UE) in a mobile communication system using carrier aggregation in which communication is conducted over a plurality of component carriers, and a terminal for the method are disclosed. When the UE performs a contention-based random access procedure in the mobile communication system to which CA technology is applied, the UE considers an uplink grant signal as a contention resolution message when receiving the uplink grant signal from a eNB only when the uplink grant signal is received through a downlink CC corresponding to an uplink CC used to transmit a random access preamble or a third message, to thereby prevent contention resolution from being erroneously ended.

Abstract: In a wireless mobile communications system, a method for controlling a radio resource allocation is provided. A network transmits access control information to a terminal such that a request for the radio resource allocation which will be transmitted from the terminal can be controlled. The terminal selectively transmits the request for the radio resource allocation based on the received information, thus a transmission of an unnecessary request for the radio resource can be minimized, thereby preventing a waste of the radio resource.

Abstract: A method is described for operating a device in a wireless communication system. The device communicates with a base station using a subframe for the device only; detects, by the device, a problem with a connection between the device and the base station. The device starts a timer upon detecting the problem with the connection between the device and the base station. The device releases a restriction of using the subframe for the device only, if the timer expires. The problem with the connection between the device and the base station is associated with a radio link failure. The detection of a problem with the connection between the device and the base station comprises detecting consecutive out-of-sync indications.

Abstract: A method of performing contention resolution associated with a random access procedure includes transmitting, by the mobile communication terminal, a random access preamble; receiving, by the mobile communication terminal, a random access response; transmitting, by the mobile communication terminal, an uplink message and starting a contention resolution timer once the uplink message is transmitted; and receiving, by the mobile communication terminal, a physical downlink control channel (PDCCH), wherein the mobile communication terminal considers whether a contention resolution is successful or not by using either a cell radio network temporary identity (C-RNTI) on the PDCCH or a UE Contention Resolution Identity on a downlink shared channel (DL-SCH) associated with the PDCCH, wherein the mobile communication terminal considers the contention resolution successful and stops the contention resolution timer when the C-RNTI on the PDCCH matches the uplink message, and when the UE Contention Resolution Identity on the DL-SCH matches the uplink message.

Abstract: A method is provided for performing, by a user equipment (UE), a power headroom reporting (PHR) procedure in a wireless communication system. The UE determines whether at least one PHR has been triggered and not canceled, and whether an uplink (UL) resource can accommodate a PHR media access control (MAC) control element (CE) plus its subheader as a result of a logical channel prioritization (LCP). The UE transmits the PHR MAC CE, if it is determined that the at least one PHR has been triggered and not canceled, and that the UL resource can accommodate the PHR MAC CE plus its subheader.
