Method for building a set of mobile stations in a MIMO system, corresponding mobile station, base station, operation and maintenance center, and wireless communication network

摘要

The invention relates to a method for building sets of mobile stations in a radio communication network (RCS1), wherein the method comprising the steps of: transmitting (M1/1) reference signals from a base station (BS1) to at least two mobile stations (MS1, MS2, MS3) for being able to determine channel properties of a downlink channel (DL1) between the base station (BS1) and the 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) each comprising a first component indicating a channel quality; transmitting (M1/7) the first and the second feedback information from the first one and the second one of the at least two mobile stations (MS1, MS2, MS3) to the base station (BS1); and building (M1/9) a mobile station set according to the first and the second feedback information at the base station (BS1), wherein the channel quality is a parameter of a downlink beam with a largest received carrier power of at least three downlink beams (DB1, DB2, DB3, DB4) of said downlink channel (DL1).
