METHOD AND APPARATUS FOR SCHEDULING BASED ON LATTICE REDUCTION AIDED PRECODING IN MULTIPLE INPUT MULTIPLE OUTPUT WIRELESS COMMUNICATION SYSTEM

摘要

PURPOSE: A method for scheduling based on LRA(Lattice Reduction Aided) precoding in a wireless communication system which obtains multi user diversity and a device for the same are provided to maximally obtain multiuser diversity, thereby providing high performance and maintain similar complexity. CONSTITUTION: A feedback information receiver receives a feedback about channel information from terminals controlled by a base station. A scheduler(101) performs algorithm. The algorithm generates the channel information based on lattice reducing conversion channel information, and selects a channel corresponding to lattice reducing conversion channel information which the size of the orthogonal component is the largest. A LRA precoder(102) performs a LRA precoding of data transmitted to terminals corresponding to the selected channel.
