1. A device-to-device (D2D)-enabled node for a wireless communication network, wherein:the D2D-enabled node is configured to perform D2D communication with one or more other D2D-enabled nodes and is configured to perform a D2D operation on a first carrier frequency or band (f1) and a cellular operation on a second carrier frequency or band (f2);
the D2D-enabled node is further configured to obtain information about D2D operation on f1 and to obtain information about cellular downlink (DL) operation on f2, and is configured to adapt the D2D operation, based on the obtained information about D2D operation on f1 and the obtained information about cellular DL operation on f2, to meet one or more requirements or to comply with one or more rules;
wherein the obtained information about cellular DL operation on f2 comprises information identifying resource usage by cellular DL transmissions; and
wherein adapting the D2D operation comprises adjusting usage of resources for D2D operation to avoid at least some use of resources overlapping with cellular DL operation, based on the information identifying resource usage by cellular DL transmissions.
