Radio communication control apparatus and radio communication control method

A radio communication control method comprising:

• an acquisition step for acquiring radio spectrum environment information indicative of radio spectrum environment of a communication terminal, being an opposite party of communication, and radio spectrum environment information of a self-apparatus;
• a parameter decision step for deciding a spreading factor in a transmission signal among transmission parameters, based on the radio spectrum environment information acquired in the acquisition step;
• a control signal transmission step for transmitting the transmission parameter decided in the parameter decision step, to the communication terminal;
• a parameter setting step for setting the transmission parameter decided in the parameter decision step;
• and
• a communication step for performing simultaneous transmission and reception using the same frequency with the communication terminal, using the transmission parameter set in the setting step.

A radio communication control apparatus comprising:

• an acquisition unit for acquiring traffic priority information indicative of a priority to a transmission signal in a communication terminal, being an opposite party of communication, and traffic priority information of a self-apparatus;
• a parameter decision unit for deciding a spreading factor in a transmission signal among transmission parameters, based on the traffic priority information acquired by the acquisition unit;
• a control signal transmission unit for transmitting the transmission parameter decided by the parameter decision unit, to the communication terminal;
• a parameter setting unit for setting the transmission parameter decided by the parameter decision unit;
• and
• a communication unit for performing simultaneous transmission and reception with the communication terminal using the same frequency using the transmission parameter set by the setting unit.
