description: In this paper, we present a model of visible light  communication (VLC) systems which exploit light beams for  downlink transmission. A calculation method is proposed for light  beam configuration which guarantees no blind areas in the whole  VLC coverage while minimizing the number of light beams. As a  major contribution in this paper, a light beam allocation algorithm  is proposed which aims to eliminate interferences between inter  VLC Access Points (inter-APs) by using information of incoming  data queue length and co-channel interference (CCI) conditions to  decide which VLC beams are used for transmitting data to  appropriate user equipments (UEs). By deploying the proposed  algorithm, CCI can be eliminated because noise-effected regions  and noise-free regions can be separated. Performance of the novel  light beam allocation algorithm is analyzed, evaluated and then  compared with that of another light beam allocation method using  the Round-Robin algorithm. Performance results show that there  are significantly improvements in SINR, user throughput and  packet delay parameters when deploying the proposed light beam  allocation algorithm.
