Base station selection control method in cellular mobile communication system

Abstract

In the cellular mobile communication system, at the point where the base station is separated, the increase in the attenuation of the desired signal and the increase in the amount of interference signal will lead to a decrease in communication quality, making it difficult to perform high-speed data communication. In order to solve the above problems, the mobile station M at the point In places such as D where the attenuation of radio waves is small, OFDM signals are used to aggregate and transmit data x, y, and z through traffic channels, and data communication is performed at the maximum communication speed. On the other hand, when the mobile station M moves from the point D to the point E, since it is far away from any of the base stations A, B, and C, the data x, y, and z are divided into three, and the interference resistance is high. The diffused OFDM signal, etc., enhances the interference resistance, and the data x, y, and z are sent from the three base stations A, B, and C at roughly the same time, equivalently realizing high-speed data transmission.
