USER SCHEDULING METHOD IN MULTIPLE ANTENNA SYSTEM

摘要

A user scheduling method in a multiple antenna system is provided to obtain a precoding matrix and a weight matrix by selecting the users, who are supposed to receive real data, among active users. Nmax for active users is determined(S300), and the number of users who are supposed to receive data is determined(S320). The maximal temporary user set BUmax having maximal capacity is obtained from M number of active numbers(S340). From the precoding matrix and the weight matrix, a transmission signal vector for the users who belong to the maximum temporary user set is generated(S360). The transmission signal vector is transmitted to the users(S380).
