1. A method performed by a second Wireless Communication Device, WCD, to ascertain whether a Device-to-Device, D2D, link between a first WCD and the second WCD in a cellular communications system is able to satisfy a requirement, the method comprising:
attempting to receive a plurality of synthetic packet transmissions from the first WCD over a D2D link using a current resource allocation, each synthetic packet transmission of the plurality of synthetic packet transmissions comprising R replicas of a respective synthetic packet, wherein R is a natural number that is greater than or equal to 1;
determining that the D2D link violates the requirement based on results of the attempting to receive the plurality of synthetic packet transmissions; and
upon determining that the D2D link violates the requirement, sending, to a Centralized Scheduler, CS, in the cellular communications system, a violation notification that notifies the CS that the D2D link violates the requirement when using the current resource allocation.
