基站服务多小区时，各个小区中不同位置对应不同容量的染色图。其中小区为蜂窝小区，小区中用户随机分布。-Each location has its own capacity with the change of distance between BS and users when BS serves for multicells where the location of users are randomly located.

小区内随机产生用户位置，主要用于多小区通信系统仿真(User locations are randomly generated in the cell, mainly used for multi-cell communication system simulation)
