RADIO COMMUNICATION METHOD, RADIO COMMUNICATION SYSTEM, AND RADIO BASE STATION

摘要

PROBLEM TO BE SOLVED: To realize linear precoding which can obtain an excellent BER characteristic with a smaller amount of operations even in a case where a constellation distance between a desired signal and an interference signal is short or the like. SOLUTION: In a radio communication method, a base station performs a step (S101) of calculating a transmission weight for linear precoding for a modulated signal to be transmitted to each user, a step (S106 or S107) of correcting the transmission weight so as to rotate a phase of an interference signal in the user, and a step of performing the linear precoding to the modulated signal to be transmitted by using the corrected transmission weight.
