This paper investigates an application of simultaneous wireless information and power
transfer (SWIPT) in a cognitive radio (CR) inspired non-orthogonal multiple access (NOMA)
framework with an aim to support simultaneous multicast services of delay sensitive traffic to
a high priority multicast group and a low priority multicast group, modeled as primary user
(PU) and secondary user (SU) respectively. A cooperative NOMA protocol is proposed
where the nodes in the SU multicast group (SU-MG), located in between a common base …
