摘要： In this second radio channel setting example, the grouping is done for each radio mobile stations 98 running on the same lane. A different radio channel is assigned to each group. Accordingly, this prevents the beam patterns using the same channel from intersecting with each other (interfering with each other). Actually, as shown in FIG. 10B, the pas or the pursuit does not occur between the radio mobile stations 98. Thus, the same radio channel is assigned to each radio mobile stations 98 running on the same lane so as to avoid the interference in the same radio channel. Hence, the same radio channel can be repeatedly used.

摘要： This is a radio communication system having a radio base station controller 20 which is connected to a plurality of base stations 10n−1, 10n and 10n+1, and then assigns a fixed channel to each of radio mobile stations 18a, 18b and 18c, and further controls the beam patterns of the radio base stations 10n−1, 10n and 10n+1, and accordingly carries out the radio communications with the radio mobile stations 18a, 18b and 18c. The radio base station controller 20, when transmitting to and receiving from the different radio mobile stations 18a, 18b and 18c to which the same channel is assigned, controls the beam patterns so that the channels do not interfere with each other.
