Communication control device, communication control method, and communication device

An electronic device comprising:

• circuitry configured to
• perform wireless communication via one or more frequency channels in a secondary system, the one or more frequency channels being determined to be utilized in the secondary system by a primary system;
• and
• receive one or more link direction configurations for the secondary system among a plurality of candidates, each of the plurality of candidates indicating an uplink or downlink direction for each sub-frame of a frame, wherein
• the link direction configuration is applied to the wireless communication in the secondary system, each of the one or more link direction configurations being applied to each of the one or more frequency channels,
• the plurality of candidates includes at least one of a first link direction configuration and a second link direction configuration, the first link direction configuration including more sub-frames dedicated to the downlink direction than sub-frames dedicated to the uplink direction, the second link direction configuration including more sub-frames dedicated to the uplink direction than sub-frames dedicated to the downlink direction, and
• in a case that the second link direction is applied to each of the one more frequency channels, which are separated in frequency from one or more frequency channels of the primary system, additional resources for the uplink can be secured resulting in increased throughput of the uplink.
