METHOD FOR INTER-BEAM INTERFERENCE REDUCTION USING CROSS POLARIZATION AND METHOD FOR TRANSMITTING/RECEIVING SIGNAL

摘要

Disclosed are a method for inter-beam interference reduction using cross polarization and a method for transmitting/receiving a signal. A transmitting method of a base station in a wireless communication system, includes: configuring a first parameter for forming a first beam having first polarization with respect to a terminal located in a first sub-sector, and configuring a second parameter for forming a second beam having second polarization with respect to a terminal located in a second sub-sector; and transmitting a signal to each terminal by forming the first beam using at least one antenna based on the configured first parameter and forming the second beam using the at least one antenna based on the configured second parameter, wherein a frequency band equal to a frequency band of the first sub-sector is allocated to the second sub-sector in a cell in the base station.
