Abstract: A method of managing intercell interference in a network and an apparatus for performing the method are disclosed. The method of managing intercell interference by a base station included in the network includes selecting a beam pattern from among a plurality of beam patterns for transmitting and receiving data between the base station and users included in the network, activating a beam corresponding to the selected beam pattern, performing a user’s scheduling on users included in the activated beam, and allocating transmission power to the activated beam to transmit and receive data to and from the users selected by the user’s scheduling.

Abstract: A method and an apparatus for controlling an MBMS service provided at a specific location in an LTE system. In an MBMS service system of the present invention, it is possible to efficiently control and manage a valid MBMS service only at a specific location. For example, it is possible to more efficiently manage the effective MBMS content only in the specific cell or the specific cluster (set of the specific cells).

Abstract: A apparatus for wireless connection reconfiguration in a wireless communication system and a method thereof are proposed. The disclosed generally relates to the wireless communication system and, more particularly, to the apparatus for the wireless connection reconfiguration in the wireless communication system and the method thereof. The method for a base station (BS) in the wireless communication system includes a process of transmitting a connection reconfiguration request (RRCReconfiguration) message to a user equipment (UE), a process of reconfiguring the UE on the basis of the connection reconfiguration request message, and a process of completing the reconfiguration of the UE on the basis of a connection reconfiguration complete (RRCReconfigurationComplete) message received from the UE.

Abstract: A second terminal which performs direct communication with a first terminal receives a signal for measuring a radio channel from the first terminal and calculates radio channel quality. Further, the second terminal calculates a data error rate using replay information indicating whether data are received and compensates for the radio channel quality depending on a data error rate. The second terminal reports the compensated radio channel quality to a base station and the base station uses the compensated radio channel quality to allocate resources used in direct communication.

Abstract: A method for controlling, by a base station, uplink transmission power of a mobile terminal. The base station receives an available transmission power amount of the mobile terminal from the mobile terminal. The base station determines a target channel quality value corresponding to a current location of the mobile terminal, on the basis of the available transmission power amount.The base station determines a received channel quality value using an uplink data channel received from the mobile terminal. Further, the base station determines a transmit power control (TPC) using a difference between the target channel quality value and the received channel quality value.
