The Basestation (BS) is a conrol communication machine in cellular communication systems. BS can transmit and receive signals interacting with mobile stations (MS).

BS transmits to and receives from multiple individual mobile terminals so as to help mobile users communicate with core-networks in a wireless cellular networks. Moreover, the base station coordinates transmission and reception of all mobile users in a network. By the appropriate coordination of the basestation, the mobile terminals can communicate with a base station simultaneously with other mobile users almost no or minimal experiencing inter-user and other wireless interference signals.
