Abstract:
Conventionally, CoMP (coordinated multi-point) transmission has been utilized for the performance improvement in the cell edge of multi-cellular systems. This paper describes CoMP scheme using multistream transmission for the disaster recovery:~if base stations (BSs) lose their function by disaster attacks in some cells, user terminals (UTs) in those cells should connect to BSs in a long distance located outside their own cells under the situation where demands for the communications increase. In this case, cooperative transmission/reception of signals is considered to be helpful to keep the quality of communications. Here, our investigation is on two typical patters of allocation of cells with BS destruction, and the effectiveness of the cooperation in downlink scenario is shown through computer experiments using cooperative and noncooperative methods in the entire cell.
