1. A communication system comprising:
- a base station apparatus;
a plurality of radio access units; and
a main unit configured to relay signals between the base station apparatus and the plurality of radio access units, wherein;
each of the plurality of radio access units is configured to;
define a single cell of a first communication system managed by the base station apparatus, in combination with other radio access units in the plurality of radio access units, anddefine a cell of a second communication system managed by a base station function of each of the plurality of radio access units.

Abstract
A plurality of radio access units form the single cell of a first communication system, while forming respective individual multi-cells of a second communication system within the single cell. The plurality of radio access units transmit a downstream signal of the first communication system input from a main unit to a terminal using the first communication system of the single cell, while each transmitting a downstream signal of the second communication input from the main unit to a terminal using the communication system of the corresponding respective one of the multi-cells.
