Multicast transmission has several distinctive traits as opposed to more commonly studied unicast networks. Specially, these include - identical packets must be delivered successfully to several nodes, outage could simultaneously happen at different receivers, and the multicast rate is dominated by the receiver with the weakest link in order to minimize outage and retransmission. To capture these key traits, the authors utilize a Poisson cluster process consisting of a distinct Poisson Point Process (PPP) for the transmitters and receivers, and then define the Multicast Transmission Capacity (MTC) as the maximum achievable multicast rate times the number of multicast clusters per unit volume, accounting for outages and retransmissions.
