Communication control device, communication control method, program, terminal device, and communication control system

A communication control method for controlling radio communication conducted by one or more terminal devices according to a time-division duplex scheme in an electronic device, the communication control method comprising:

• configuring, for each frame that includes a plurality of subframes, a first link direction configuration and a second link direction configuration expressing a link direction per subframe;
• signaling the first link direction configuration to a terminal device belonging to a first terminal group on a first cycle;
• and
• signaling the second link direction configuration to a terminal device belonging to a second terminal group on a second cycle that is shorter than the first cycle,
• wherein the second cycle is an integer multiple of 10 milliseconds.

An electronic device comprising:

• a communication interface configured to communicate with a base station according to a time-division duplex scheme;
• and
• circuitry configured to:
• configure, according to a link direction configuration signaled from the base station, a link direction per subframe for each frame that includes a plurality of subframes, and
• cause the communication interface to receive a signaling of a second link direction configuration configured for a second terminal group to which the terminal device belongs on a signaling cycle that is shorter than a signaling cycle of a first link direction configuration configured for a first terminal group, wherein the second cycle is an integer multiple of 10 milliseconds.

A communication control system comprising:

• a base station for controlling radio communication conducted by one or more terminal devices;
• and
• a first means for:
• configuring, for each frame that includes a plurality of subframes, a first link direction configuration and a second link direction configuration expressing a link direction per subframe;
• signaling the first link direction configuration to a terminal device belonging to a first terminal group on a first cycle;
• and
• signaling the second link direction configuration to a terminal device belonging to a second terminal group on a second cycle that is shorter than the first cycle,
• wherein the second cycle is an integer multiple of 10 milliseconds.
