1. An apparatus comprising:
an interface;
a memory; and
a processor, communicatively coupled to the interface and the memory, configured to:
instruct a node to send a first cellular reference signal to a target UE (user equipment) and to another UE, the node being a cellular-communication node;
instruct, via the interface, the target UE to report to the node a first time difference, the first time difference being a first time amount between receipt of the first cellular reference signal by the target UE and transmission of a second cellular reference signal by the target UE; and
instruct, via the interface, the other UE to report a second time difference, the second time difference being a second time amount between receipt of the first cellular reference signal by the other UE and receipt of the second cellular reference signal, in a cross-link interference resource, by the other UE.
