Method and device for mitigating inter-cell interference
The present invention provides a method for mitigating inter-cell interference. To this end, the present invention includes a second signal transmission step in which, when a transmission symbol to be transmitted to a first receiver is S and a transmission symbol to be transmitted to a second receiver is Z, a symbol S2k (k is an integer) is transmitted to the first receiver through a first transmission antenna according to a first pattern, a symbol S2k* is transmitted to the first receiver through a second transmission antenna, a symbol S2k+1 is transmitted to the first receiver through a third transmission antenna, a symbol S2k+1* is transmitted to the first receiver through a fourth transmission antenna, and symbols Z4k to Z4k+3 and symbols Z4k* to Z4k+3* are transmitted to the second receiver through fifth to eighth transmission antennas according to a second pattern different from the first pattern.
