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

At least one non-transitory computer-readable storage medium storing processor-executable instructions for providing one or more second communication services using at least a part of a frequency band assigned to a first communication service that, when executed by at least one computer hardware processor, cause the at least one computer hardware processor to perform the acts of:

• transmitting, to a communication control device, first service area information for estimating a service area of the one or more second communication services provided by the secondary usage node and access technique information indicating a radio access technique usable by the secondary usage node, wherein the secondary usage node is a first secondary usage node of a plurality of secondary usage nodes;
• and
• receiving, from the communication control device, data indicative of a channel recommended for use by the secondary usage node for the one or more communication services, data indicative of a common radio access technique, or both, based on whether (a) two or more service areas of the one or more second communication services, which are estimated based on the first service area information and second service area information from a second secondary usage node of the plurality of secondary usage nodes, overlap and (b) whether the secondary usage node and the second secondary usage node can be configured to use the common radio access technique.
