Method for building sets of mobile stations in SDMA systems, corresponding mobile station, base stations, operation and maintenance centre and radio communication network

摘要

The invention relates to a method for building sets of mobile stations in a radio communication system (RCS1), wherein the method comprises transmitting (M1/1) first reference signals by a base station (BS1, BS2, BS3), receiving (M1/2) the first reference signals by at least two mobile stations (MS1, MS2, MS3), determining (M1/3, M1/4, M1/5, M1/6) a first feedback information at a first one of the at least two mobile stations (MS1, MS2, MS3) and a second feedback information at a second one of the at least two mobile stations (MS1, MS2, MS3) comprising each a first component indicating a downlink beam of at least two downlink beams (DB1, DB2, DB3, DB4), transmitting (M1/7) the first feedback information and the second feedback information to the base station (BS1, BS2, BS3), receiving (M1/8) the first feedback information and the second feedback information at the base station (BS1, BS2, BS3), and building (M1/9) a mobile station set of at least two of the at least two mobile stations (MS1, MS2, MS3), wherein the downlink beam is a downlink beam with a largest received carrier power of the at least two downlink beams (DB1, DB2, DB3, DB4) and the first feedback information and the second feedback information further comprises a second component indicating a further downlink beam with a fewest received carrier power of the at least two downlink beams (DB1, DB2, DB3, DB4) .
