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

摘要

Provided are a method for mitigating an interference between adjacent beams using a cross polarization, and a transceiving method. A transmitting method of a base station in a wireless communications system comprises the following steps: configuring a first parameter to form a first beam having a first polarization with respect to a terminal positioned in a first sub-sector, and configuring a second parameter to from a second beam having a second polarization with respect to a terminal positioned in a second sub-sector; and forming the first beam by using at least one antenna based on the configured first parameter, and forming the second beam by using the antenna based on the configured second parameter so as to transmit a signal to each terminal. The second sub-sector has a frequency band, which is the same with the first sub-sector, allocated in a cell of the base station and may be a sub-sector adjacent to the first sub-sector.
