Multiplexing device and method

A multiplexing device for multiplexing uplink signals transmitted from each of a plurality of radio devices and outputting the multiplexed signal to a radio control device, the multiplexing device comprising:

• a memory;
• and
• a processor coupled to the memory and configured to
• perform a calculation processing that calculates a power value of the uplink signal for each radio device,
• perform a determination processing that determines whether or not noise of a radio device that transmits an uplink signal is dominant among signal components included in the uplink signal, using the power value of the uplink signal calculated by the calculation processing,
• perform a blocking processing that blocks the uplink signal in which the noise is dominant in a case where the noise is determined to be dominant among the signal components included in the uplink signal by the determination processing, and
• perform a multiplexing processing that multiplexes uplink signals that are not blocked by the blocking processing among the uplink signals for each radio device, and outputs the multiplexed signal to the radio control device.
