A first network node and a second network node are disclosed. The first network node comprises a processor and a transceiver. The transceiver is configured to receive a first signal S1 comprising a network information message indicating network information associated with a first network operator in a region. The processor is configured to determine an allocation of frequency resources for operation W1, for the first network operator or a second network operator in the region, based on the network information, and the processor is further configured to determine a density of network nodes for operation λb or a frequency spectrum access price, for the first network operator or the second network operator, based on the network information. Corresponding methods, a computer program, and a computer program product are also disclosed.
