On modeling the effects of multicast traffic servicing in 5G NR networks

Multicasting in wireless access networks allows efficient provision of a service to a group of subscribers and is useful for reducing the resource required to serve user equipments requesting the same data. The support of this feature in current 5G New Radio (NR) technology and future subterahertz (sub-THz) 6G systems faces challenges associated with the use of the directional beamforming phased array antennas. The presented multicast and unicast traffic service model allows one to explore the range of 5G/6G network parameters to reduce the density of base stations while maintaining the quality of services provided to subscribers.
