Abstract
A distributed antenna system and aggregation station of the present disclosure may prevent or reduce radio wave interference when there is a positional relationship in which a plurality of base stations and a plurality of user terminals are arranged on a straight line. The distributed antenna system receives, from each of the base stations, communication path information with each of accommodated user terminals, for each user terminal; and calculates, in a case where it is determined that the plurality of the respective base stations and the plurality of user terminals are arranged on the straight line, transmission weights of respective transmission beams transmitted by the plurality of the respective base stations to the plurality of respective user terminals based on the communication path information for each user terminal received by the receiver. The base stations transmit the respective transmission beams based the respective transmission weights calculated.
