A study of space-time packet scheduler with exchanging beam schedule information

Abstract

A novel technique to reduce inner and inter cell interference for the cellular packet data transmission on the downlink is proposed. In this method, base transmission station (BTS) has a space-time scheduling which uses beam schedule information of adjacent cell BTSs. This method drastically improves frequency efficiency by suppression of inter-cell interference. According to the simulation results, the frequency efficiency of twelve-beams array antenna system can be improved on by eighty percent compared to the scheduling without using beam schedule information.
