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.

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).
