A method and an apparatus for an inter-cell load balance in a wireless communication system are provided. The method of an inter-cell load balance of a first base station in a heterogeneous network wireless communication system including the first base station and a second base station includes configuring a first reserve area for the second base station, for the inter-cell load balance and controlling an inter-base station load balance according to the first reserve area.

Method and apparatus for inter-cell load balance in wireless communication system

The present invention relates to a method and an apparatus for applying wireless resources in order to control inter-cell interference in a heterogeneous network system. The method for applying wireless resources provided by the present invention generates an almost blank subframe (ABS) pattern on the basis of the type of data transmitted from at least one of a first base station and a second base station, applies a non-ABS or an ABS to wireless resources of the first base station according to the generated ABS pattern, and performs data communication by using the wireless resources to which the ABS has been applied.

Method and apparatus for applying resources in heterogeneous network system

The present invention relates to a method and an apparatus for an inter-cell load distribution and interference mitigation in a wireless communication system, and the inter-cell load distribution method by a first base station in a heterogeneous network wireless communication system including the first base station and a second base station for solving the above-described problem, comprises the steps of: setting a reserved area for the second base station so as to distribute an inter-cell load; and managing a terminal according to the reserved area.

Method and apparatus for inter-cell load distribution and interference mitigation in wireless communication system

Disclosed is a 5G or pre-5G communication system to be provided for supporting a data transmission rate higher than that of a 4G communication system such as LTE. According to one embodiment of the present invention, a method by which a device for adjusting the interference of a plurality of base stations transmits and receives data to and from the plurality of base stations comprises: receiving channel information of a terminal connected to one or more macro base stations or to one or more small base stations from the one or more macro base stations or the one or more small base stations; receiving ABS pattern information from the one or more macro base stations; generating, for each base station, interference control information for the one or more macro base stations or the one or more small base stations on the basis of the ABS pattern information and the channel information of the terminal connected to the one or more macro base stations or to the one or more small base stations; and transmitting, to each base station, the interference control information generated for each base station.

Interference control method and device in wireless communication system

A method for transmitting a signal of a base station in a wireless communication system, according to an embodiment of the present invention, comprises the steps of: transmitting transmission standby traffic indication information to a node when a first traffic is received in a first duration; and determining whether to transmit the transmission standby traffic indication information to the node in a second duration, on the basis of whether the transmission standby traffic indication information has been transmitted in the first duration and whether a second traffic has been received in the second duration.

Method and device for transmitting signal of base station in wireless communication system

The present invention relates to an interference control method and an apparatus therefor in a heterogeneous system. To this end, the present invention relates to an interference control method for an almost blank subframe (ABS) ratio determination apparatus in a wireless communication system in which a cell range expansion (CRE) area is defined, comprising the steps of: receiving information about data load within a cell from one or more first cells, and one or more second cells; determining an ABS ratio on the basis of the wireless resource requirements of a CRE terminal with respect to the wireless resource requirements of all cells that are obtained from the data load information; and transmitting the determined ABS ratio to one of the first cells and the second cells.
