Abstract:
As a promising approach to mitigate the performance degradation of multi-cellular network in cell-edge region, Base Station Cooperation (BSC) is collecting attentions. This paper investigates ``how much'' BSC using practical algorithm could improves the performance of the system, when the shape and size of cells are flexibly changed based on BS location and inter BS-UT channel condition. Here, we consider multistream transmission assuming that BSs and User Terminals (UTs) are all equipped with multiantenna. In multistream case, interferences arriving from surrounding cells consist of larger number of data sequences than single stream case, hence first, we investigate the nature of inter-cell interference. Next, the performance gain of BSC is evaluated using five types of algorithms with and without BSC through computer simulations. The results show that BSC achieves about three times larger capacity compared to cooperation less scheme.
