WIRELESS COMMUNICATION BASE STATION APPARATUS AND WIRELESS COMMUNICATION METHOD IN MULTICARRIER COMMUNICATION

摘要

A base station apparatus wherein the interference suppression symbol combination can be performed in a case of using the repetition technique in a multicarrier communication. Inabasestation (100), arepetitionpart (103) repeats or copies each of data symbols received from a modulating part (102) to create a plurality of same data symbols. A phase rotating part (106) imparts, in accordance with a phase rotation angle set by a setting part (107), phase rotations to the pilot and data symbols received from a multiplexing part (105). At this moment, the phase rotating part (106) imparts the phase rotations of the same angle to the pilot and data symbols assigned to the same subcarrier. Further, the phase rotating part (106) causes the phase rotation difference between the same data symbols in a cell to be different from the phase rotation difference between the same symbols in an adjacent cell.
