Abstract :
This letter investigates the resource allocation in interweaved primary and secondary multicast networks (PMNs and SMNs, respectively), where an SMN can access the spectrum licensed for a PMN only if the PMN is not active. Given the number of primary terminals in a PMN and the detection probability requirement, the secondary power that is maximally allowable while maintaining the primary outage requirement is provided in closed form. In addition, the number of secondary terminals that can be maximally admitted is also presented while keeping a secondary transmission failure target.
