Abstract
A method and apparatus for scheduling multiuser terminals in a communication system is provided. A receiver receives feedback information from a plurality of user terminals. A user grouping unit selects terminals having a maximum Signal to Interference plus Noise Ratio (SINR) among terminals having the same beam index and beam subset index, from among the plurality of user terminals, and generates terminal groups using the selected terminals, each terminal group including terminals having the same beam subset index. A group scheduling unit calculates a throughput of each of the terminal groups to determine which terminal group has the maximum throughput. A random precoding unit generates random beam vectors corresponding to terminals included in the terminal group determined to have the maximum throughput, and transmits data for user terminals, included in the terminal group determined to have the maximum throughput, over the generated random beam vectors.
