“…While all the aforementioned works do not consider multicast transmission services in HetNets, the following studies investigate the resource allocation problem for multicast transmission. Work [22] addressed the optimal multicast resource allocation problem by using Lagrangian dual decomposition method. A novel subcarrier assignment algorithm integrated with frequency reuse scheme, was devised to enhance spectrum resource utilisation in [23].…”

“…Therefore, literature [5] proposed a resource allocation scheme for multicast wireless system considering the resource utilization fairness among different multicast groups. Work [6] addressed the optimal multicast resource allocation problem by using Lagrangian dual decomposition method for a layered coding multicast network. However, most of the available studies on multicast services are limited to traditional passive antenna systems.…”

In this paper, we investigate a preference-aware multicast mechanism in active array aided LTE (Long Term Evolution) networks. An active antenna system can direct vertical beams in different horizontal and vertical directions, so the amount of energy delivered is more concentrated on the target users. Employing the active array, each multicast group is provided with an individual beam with specific downtilt for delivering shared video to the whole users in the group. For the multicast system, our objective is to maximize the total throughput, subject to the constraints of subcarrier, antenna downtilt, as well as horizontal angles and the vertical half power bandwidth constrains. To solve the problem, individual beams is steered for multicast groups. Furthermore, a novel subcarrier assignment scheme is proposed for saving the spectrum resource. Simulation results demonstrate the throughput and the spectral efficiency enhancement of our proposed scheme over other conditional schemes.
