“…First, we would like to study the accuracy of the proposed heuristic algorithms without "external disturbances" that are always present in the system serving the mixture of traffic types and multiple competing multicast sessions. Secondly, to model the system with both unicast and multicast traffic, one needs to take additional assumptions as multicast traffic is known to occupy resources of the system more aggressively and eventually, under high multicast load conditions may fully occupy the system resources as we have shown in [8]. Nevertheless, the approach proposed in this paper can be extended to capture multiple multicast sessions and the presence of unicast sessions as well.…”

“…The algorithm's goal is to determine the groups, which will be served simultaneously, and the corresponding transmit power to minimize the ratio of occupied to Algorithm 2: Modified Incremental Multicast Grouping [17], L ≥ 1 available resources. Thus, the algorithm works until all groups are deleted from S M (lines [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. We also use D (m) to denote a set of groups to be served at a time slot m. The algorithm selects the worst (in the sense of the needed power) group from S M and adds this group to set D (m) (lines 7-9).…”

“…Therefore, an explicit prioritization mechanism is needed at the NR BS to achieve a trade-off between unicast and multicast session drop probabilities. Later, in [32], a framework that applies stochastic geometry and queuing theory to estimate the NR AP parameters in the system where multicast and unicast traffic are simultaneously supported is proposed. In [33], 5G NR Mixed Mode (MM) to enable the use of multicast in the 5G NR Release 17 is proposed.…”

“…Non-orthogonal multiple access (NOMA) system is considered in [34], where a cooperation strategy for both unicast and multicast users by sharing the same time/space/frequency resource is designed. However, NOMA deployment in the 5G NR mmWave is still under discussion by 3GPP [32].…”
