Abstract: PURPOSE: A method and an apparatus for transmitting scanning start information of a heterogeneous access network are provided to minimize power consumption by preventing the unnecessary scanning of a heterogeneous access network in a terminal at a boundary region. CONSTITUTION: A receiver(200) supports a plurality of access systems and comprises: a receiving circuit for receiving a scanning threshold value from a transmitter; a first measurement module(261) which measures the channel quality of a serving cell; and a second measurement module(262) which starts scanning a neighbor cell that is a heterogeneous access network, when the channel quality of the serving cell is lower than the channel quality threshold value. In addition, the receiver can further comprise a handover module which performs a handover to the neighbor cell when the channel quality of the neighbor cell measured by the second measurement module is higher than the channel quality of the serving cell.

Abstract: PURPOSE: A method and a device for management of a femto base station are provided to reduce inter-cell interference by minimizing the amount of information that is broadcasted by a femto cell base station even though the terminal to be managed does not exist. CONSTITUTION: A reception unit(112) receives an interval changing request from a second base station which includes a first cell and manages a second cell larger than the first cell. An interval charger(114) converts the interval of the first base station according to the interval conversion request. If the first base station is an unavailable interval, a broadcasting unit(111) does not perform broadcasting. If the first base station is a partial available interval, the broadcasting unit broadcasts only a preamble and simple broadcasting information. If the first base station is the available interval, the broadcasting unit broadcasts system information.

Abstract: PURPOSE: A method and an apparatus for providing a multimedia broadcast multicast service are provided to supply a multimedia broadcast multicast service having the advantage of preventing unnecessary the transmission and retransmission of data by checking for a case in which there is no terminal receiving the service after the service has started and controlling the amount of interference due to feedback overhead. CONSTITUTION: A base station(300) requests expected reception data for an MBMS service through a broadcast channel of a system in order to determine the number of terminals required(10) prior to or during the broadcast of the MBMS service(S310). When a service is requested, the terminal acquires the positional information of the control channel in the broadcast channel and responds to the service request through an allocated feedback channel(S320). The base station determines the number A of terminals that is verified by the response to the service request, and since the determined number A of terminals is smaller than the predetermined unit-cell and multi-cell thresholds, a transmission method is determined as a unit-cell transmission method(S330). In addition, the base station allocates a common feedback channel to the unit cell through the control channel(S340) and transmits the unit cell MBMS service data through the transmission channel(S350). The terminal determines whether or not the data packet has an error by performing CRC after decoding the received service data(S360). In addition, when the data packet has an error, error reporting is performed through the common feedback channel(S370). The base station retransmits corresponding MBMS data in accordance with the error reporting of the terminal 10(S380). Herein, the retransmission of the MBMS data retransmits previously transmitted data in order to correct an error generated by the harsh environment of a radio channel. For example, the retransmission of the MBMS data can include a hybrid automatic repeat request scheme.
