Method for reducing inter-cell interference in cooperative multi-cell wireless communication system, and apparatus for same

摘要

The present invention relates to a method for reducing inter-cell interference in a wireless communication system and to an apparatus for same. More specifically, a method for reducing the inter-cell interference between serving cells in the cooperative multi-cell wireless communication system comprises the steps of: receiving from an adjacent cell interference information on a specific wireless resource region; and reducing interference with respect to the specific wireless resource region based on the interference information, wherein the specific wireless resource region is a wireless resource region that the serving cell uses by changing the purpose of a wireless resource.

主权项

1. A method for reducing inter-cell interference of a serving cell in a cooperative multi-cell wireless communication system, the method comprising the steps of:
reconfiguring, by the serving cell, a specific subframe as a downlink subframe, the specific subframe being one subframe among plural uplink subframes configured by a SIB (system information block); receiving, by the serving cell, interference information on the specific subframe from a neighboring cell via an X2 interface, wherein the interference information is configured in the form of a bitmap represented by 10 bits; and reducing, by the serving cell, interference with respect to the specific subframe on the basis of the interference information.
