In the next generation mobile communication such as the 5th generation system, high-frequency band such as millimeter waves is used for the purpose of ensuring wide frequency bandwidth in order to realize high speed and large capacity communications. However, the high frequency band suffers from large propagation loss between a transmitter and a receiver. To compensate the loss by directional gain of antennas, it is necessary to form a propagation path mainly by the direct wave. To realize stable communication using the high frequency band, it is necessary to understand the characteristics of LOS (Line-of-Sight) probability between a base station and a mobile station in system design of the mobile communication systems. In ITU-R, a LOS probability model for an isolated base station is shown. This is called the d1/d2 model, and the LOS probability of various environments can be expressed by changing the their values. However, in an actual mobile communication system, since it is a cellular environment in which multiple base stations are placed over the whole area, the LOS probability in a multiple base station environment is important. Furthermore, in recent years, multiple base station cooperative transmission technology has been adopted where multiple base stations collaboratively communicate to a single mobile station to improve the transmission performance, and the LOS probability characteristic for simultaneous connection to multiple base stations is becoming more important. Therefore, in this paper, based on the physical meaning of the d1/d2 model assuming a street canyon urban city model, we analyze the LOS probability characteristics in the multiple base station simultaneous connection environment by theoretical and simulation studies. |
