Claim 0:
1. A relay device that relays between a plurality of radio devices that perform radio communication with terminals, and at least one radio control device that controls the radio devices, the relay device comprising:
a processor; and
memory including a program, the program when executed by the processor performing functions including:
determining whether or not to replicate a downlink signal received from the radio control device based on destination information included in the downlink signal, the destination information including a single destination address;
making the same number of copies of a downlink signal as the number of destination radio devices only when the determining whether or not to replicate the downlink signal is that the downlink signal is to be replicated;
transferring a downlink signal that has been determined as a downlink signal that is not to be replicated, and replicated downlink signals, to the radio devices respectively corresponding thereto;
determining whether or not to combine uplink signals received from the plurality of radio devices;
combining a plurality of uplink signals that have been determined as signals that are to be combined, for each destination radio control device; and
transferring uplink signals that have been determined as signals that are not to be combined, and combined uplink signals, to the radio control device corresponding thereto.
