Subcarrier Assignment and Power Allocation for Preference-Aware Multicast Services in Active Array Aided LTE Networks

Energy efficient user association and resource allocation in active array aided HetNets

“…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]. A subcarrier and power allocation method in the multicast system was proposed based on a property observed from the simulation in [24].…”
