Description of Invention
Dual connectivity (DC) can increase network capacity by allowing a user to connect to two Radio Access Technology (RAT) simultaneously. Nevertheless, although it offers higher network capacity, power management is a constraint in DC enabled heterogeneous networks (HetNet). This work aims to find the best trade-off between network capacity and power efficiency in DC deployed Fifth Generation New Radio (5G-NR) and Long Term Evolution (LTE) HetNet. Past works have not conducted a simultaneous optimization of power saving and capacity enhancement for DC in a Non-Standalone(NSA) setup. A novel base station pairing technique is used to determine Next Generation Node B (gNB) sleep patterns. Two algorithms, the Super Greedy algorithm and the Integer Linear Programming (ILP) - Greedy algorithm are proposed to find the optimal way to preserve network power and enhance the user throughput.
