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 user equipment (UE) and method are provided for transmitting an in-device coexistence (IDC) indication message in a wireless communication system. The UE receives a configuration message including an IDC indication from a base station. The UE transmits an IDC indication message to the base station if the UE determines that the IDC indication contains specific information. The specific information comprises an activation bit. The presence of the activation bit in the configuration message represents permission for the UE to transmit the IDC indication message. The IDC indication message includes frequency division multiplexing (FDM) assistant information. The FDM assistant information includes information on an unusable frequency in which interference from a long-term evolution (LTE) module in the UE to other coexisting technology modules in the UE or interference from other coexisting technology modules in the UE to the LTE module in the UE is expected.

Abstract: The present invention relates to a method in which a terminal reports the results of quality measurement based on a specific reference cell from among a plurality of serving cells for the terminal in a mobile communication system using carrier aggregation. The present invention also relates to a terminal apparatus for the method. For this purpose, the terminal receives measurement configuration information from a network, performs a quality measurement in accordance with the received measurement configuration information, determines whether or not a report criterion based on a specific reference cell from among the plurality of cells for the terminal is met in accordance with the measurement result, and, if the report criterion based on the specific reference cell is met, sends a report message, including the measurement results and an indicator that indicates the specific reference cell, to the network.

Abstract: The present specification proposes a scheme for controlling a deactivation timer of a cell. More specifically, the present specification proposes a method of controlling a deactivation timer of a cell in a mobile communication system. The method includes: configuring, at a user equipment (UE), a first deactivation timer of a first cell and a second deactivation timer of a second cell, wherein the first cell and the second cell belong to a same timing advance group (TAG); if the first deactivation timer of first cell expires, checking, at the UE, whether uplink timing of the same TAG is required to be maintained; and if the uplink timing of the same TAG is required to be maintained, restarting, at the UE, the first deactivation timer of the first cell.
