Abstract
A wireless communication system includes a base station and direct wave communication stations that communicate with the base station. At least one of the base station and the direct wave communication stations includes a number-of-bands switching unit that switches, on the basis of a communication state, a number of bands for direct wave communication, by dividing a band for direct wave communication. One of the plurality of direct wave communication stations receives a narrowband carrier in the divided band.
