Communication control station device, communication terminal device, and communication control method

A communication control station device comprising:

• circuitry;
• a receiver coupled to the circuitry;
• and
• a transmitter coupled to the circuitry,
• wherein, in response to determining that a long range communication operation is performed in a first communication period and a second communication period:
• the circuitry:
• decides to generate or omit generation of a first measurement request message to a first group of communication terminal devices using the first communication period based on whether an allocation of a channel time to the second communication period is implemented or not;
• generates a second measurement request message to a second group of communication terminal devices using the second communication period;
• and
• allocates a first schedule of the spatial sharing based on one or more results of measurements in the first and second communication periods;
• the transmitter:
• transmits the second measurement request message to the second group of communication terminal devices;
• and
• further transmits the first measurement request message to the first group of communication terminal devices and the first schedule of the spatial sharing to the first group of communication terminal devices, in response to the circuitry deciding to generate the first measurement request massage, and
• the receiver:
• receives the one or more results of measurements in the first and second communication periods, wherein at least one of the one or more results of measurements in the first and second communication periods are in accordance with the second measurement request message,
• wherein, in response to determining that a short range communication operation shorter than the long range communication operation is performed in any one of the first communication period and the second communication period:
• the circuitry:
• generates any one of the first and the second measurement request message requesting any one of the first and the second group of communication terminal devices using the short range communication operation;
• and
• allocates a second schedule of a spatial sharing based on results of measurement, wherein the results of measurement are in accordance with the generated any one of the first and the second measurement request message;
• the transmitter:
• transmits any one of the first and the second measurement request message to any one of the first and the second group of communication terminal devices using the short range communication operation and the second schedule of the spatial sharing to the first group of communication terminal devices and the second group of communication terminal devices, and
• the receiver:
• receives the results of measurement,
• wherein, in response to determining that the short range communication operation is performed in both the first communication period and the second communication period:
• the circuitry:
• omits generation of the first and the second measurement request messages;
• and
• allocates a third schedule of the spatial sharing in the first and second communication periods;
• and
• the transmitter:
• transmits the third schedule of the spatial sharing to the first group of communication terminal devices and the second group of communication terminal devices.
