Abstract:
1. A cell selection apparatus used in an area in which multiple communication systems coexist, comprising: a delay profile creation unit configured to create a delay profile from a received radio signal and detect amplitudes and timing of multipath arriving waves; a comparison unit configured to compare at least one delay quantity of the multipath arriving waves with a guard interval of a signal used in at least one of said multiple communication systems; and a determination unit configured to determine a cell provided by one of the communication systems to which a mobile terminal is to be connected based on the comparison result, wherein the comparison unit compares said at least one delay quantity with two or more of the guard intervals, each of the guard intervals being used in one of said multiple communication systems, and wherein the at least one delay quantity is compared with a first guard interval used in a first cell and with a second guard interval shorter than the first guard interval and used in a second cell entirely encompassed by the first cell.
