Communication device, communication method, and computer program for sensing of resources used in inter-device communications

A communication method comprising:

• allocating a resource area in which a resource is selectable by a terminal device that executes inter-device communication, and providing information regarding a range of sensing of the resource area to the terminal device;
• wherein the range of sensing is divided into a plurality of sub-sensing periods;
• and
• the method further comprising:
• providing a parameter which indicates a sub-sensing window in the sub-sensing periods.

A communication device comprising:

• a controller having circuitry configured to:
• select a resource from a resource area allocated by a base station and to
• determine a range of sensing of the resource area in accordance with a situation when inter-device communication is executed using the selected resource;
• wherein the range of sensing is divided into a plurality of sub-sensing periods, and
• the circuitry is further configured to
• receive a parameter which indicates a sub-sensing window for the sub-sensing periods.

A communication control method comprising:

• selecting a resource from a resource area allocated by a base station and setting a parameter relating to sensing by using one or more of a parameter relating to a sensing mode and a parameter relating to a packet reservation cycle notified by the base station when inter-device communication is executed using the selected resource;
• wherein the range of sensing is divided into a plurality of sub-sensing periods;
• and
• the method further comprising:
• receiving a parameter which indicates a sub-sensing window in the sub-sensing periods.
