| contents | The dense deployment of 5G heterogeneous networks (HetNets) has improved network capacity. However, it also brings frequent and unnecessary handover challenges to high-speed mobile user equipment (UE), resulting in unstable communication and degraded quality of service. Traditional handovers ignore the type of target next-generation Node B (gNB), resulting in high-speed UEs being able to be handed over to any gNB. This paper proposes a NR cell identity (NCI)-based handover decision-making algorithm (HDMA) to address this issue. The proposed HDMA identifies the type of the target gNB (macro/small/mmWave gNB) using the gNB identity (ID) within the NCI to improve the handover decision-making strategy. The proposed HDMA aims to improve the communication stability of high-speed mobile UE by enabling high-speed UEs to identify the target gNB type during the HDMA using the gNB ID. Simulation results show that the proposed HDMA outperforms other HDMAs in enhanced connection stability. |
