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, the base transmission station (BTS) has a space-time scheduling which uses beam schedule information of adjacent cell BTS. This method drastically improves frequency efficiency by suppression of inter-cell interference. According to the simulation results, the frequency efficiency of a twelve-beam array antenna system can be improved on by eighty percent compared to the scheduling without using beam schedule information.
