Abstract

The aim of this letter is to develop a new design of cognitive radio inspired non-orthogonal multiple access (CR-NOMA), which ensures that multiple new users can be supported without causing disruption to the legacy network. Analytical results are developed to characterize the statistical properties of the number of supported new users. The developed CR-NOMA scheme is compatible to various communication networks, because it can be implemented as a simple add-on. An example of using CR-NOMA as an add-on in time-division multiple access networks for age of information reduction is illustrated.
