Abstract: A method and apparatus of reporting logged measurements of an user equipment in a wireless communication system is provided. The user equipment in a Radio Resource Control (RRC) connected mode receives from a base station a Minimization of Drive Tests (MDT) configuration. The user equipment transitions from the RRC connected mode to an RRC idle mode and logs measurements based on the MDT configuration. The user equipment transmits to the base station a logging indicator indicating an availability of the logged measurement.

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 and apparatus of reporting logged measurements in a wireless communication system is provided. A user equipment in a Radio Resource Control (RRC) connected mode receives Minimization of Drive Tests (MDT) configuration from a base station and starts a validity timer upon receiving the MDT configuration. The user equipment in an RRC idle mode logs measurements based on the MDT configuration to collect logged measurements while the validity timer is running. When the validity timer is expired, the user equipment discards the MDT configuration.

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: There is provided with a method for enabling a user equipment to perform a random access procedure in a wireless communication system. The method includes transmitting a random access preamble and receiving a random access response as a response to the random access preamble. The random access response is addressed by a random access identifier. The random access identifier is mapped to radio resources used for transmitting the random access preamble. The user equipment can immediately confirm its random access response and perform further efficient random access procedure.

Abstract: A method of transmitting control information for a multimedia broadcast/multicast service (MBMS) in a wireless communication system, and a method of receiving control information for an MBMS are discussed. The method of transmitting control information according to one embodiment includes transmitting first control information including an MBMS related identifier and a fixed size of a notification bitmap to at least one user equipment; and transmitting second control information which has been changed to the at least one user equipment after the transmission of the first control information. The second control information is transmitted via a multicast control channel (MCCH).

Abstract: A method and apparatus for supporting a closed subscriber group (CSG) service is provided. The apparatus includes a memory to store CSG subscription information and a processor operatively coupled to the RF unit and memory to implement a radio interface protocol. The processor accesses a base station (BS), transmits the CSG subscription information to the BS, receives an access mode from the BS where the access mode is determined based on the CSG subscription information, and negotiates with the BS with regard to a CSG service if the access mode supports a CSG to which the apparatus belongs.
