Abstract
A user scheduling method includes: determining a maximum temporary user set of a maximum capacity among temporary user sets obtained from combinations of M number of active users; and transmitting data to users belonging to the maximum temporary user set via multiple antennas by using a preceding matrix and a weight matrix with respect to the maximum temporary user set. Users to actually receive data can be selected from among active users in a multi-antenna system, and a corresponding precoding matrix and a weighting matrix can be obtained.
