In this study, two dynamic mechanisms are proposed to mitigate inter-cell interference (ICI) in the heterogeneous cellular network (HetCN) namely: Dynamic Fixed Region Cooperation (DFRC) and Dynamic Power Allocation Mechanism (DPAM). The DFRC allows serving mSCs and other interfering base stations (BSs) to cooperate during transmission of a signal to a user. The DPAM dynamically allocates power to serving BS based on the farthest user in a cell. The study illustrates downlink interferences typically linked with a HetCN. For analysis, a macrocell (MC) network distributed with heterogeneous users is overlaid with both fixed and mobile small cells (SCs). The authors also introduced the cell-user mobility model for deployed mobile SCs in the network. The effects on network performance metrics: Sumrate, Average user throughput, and Energy efficiency are investigated with an allocation of sub 6 GHz and mmWave bands at MC and deployed SCs, respectively.

基于移动性的5G HetCN的动态节能IIC缓解技术

在这项研究中，提出了两种动态机制来减轻异构蜂窝网络（HetCN）中的小区间干扰（ICI）： 动态固定区域合作 （DFRC）和 动态功率分配机制（DPAM）。DFRC允许服务的mSC和其他干扰基站（BS）在向用户发送信号期间进行协作。DPAM基于小区中最远的用户为服务BS动态分配功率。该研究说明了通常与HetCN相关的下行链路干扰。为了进行分析，分布有异构用户的宏小区（MC）网络被固定和移动小小区（SC）覆盖。作者还介绍了网络中已部署的移动SC的小区用户移动性模型。对网络性能指标的影响：总计，平均用户吞吐量和能效分别通过在MC和已部署的SC处分配6 GHz以下和mmWave频段进行了研究。
