In this paper, a dynamic and location‐based power allocation mechanism is proposed which could be adopted at both macrocell (MC) and overlaid fixed/mobile small cells (SCs) to mitigate inter‐cell interference (ICI) effects in heterogeneous cellular networks (HetCNs). The proposed Dynamic Power Allocation based on User Location (DPAUL) mechanism allows both MCs and deployed fixed/mobile SCs to dynamically allocate transmit power to its serving base stations (BSs) based on the location of a user in the cell. The paper illustrates the mitigation of dynamic downlink interferences occurring due to the mobility of SCs and users. The mobility of cell and its users is analyzed by introducing the Cell‐User mobility (CUM) model in the network. The proposed DPAUL mechanism is compared with the authors' other ICI mitigation techniques: Dynamic Fixed Region Cooperation (DFRC) and Dynamic Power Allocation Mechanism (DPAM). The network metrics Sumrate, User throughput, Energy‐efficiency, and Outage probability are investigated with allocation of sub 6 GHz and mmWave spectrums at MCs and fSCs/mSCs, respectively.

动态和基于位置的功率分配机制，用于缓解5G异构蜂窝网络中的小区间干扰

本文提出了一种基于动态和基于位置的功率分配机制，该机制可在宏小区（MC）和覆盖的固定/移动小小区（SC）上采用，以减轻异构蜂窝网络中的小区间干扰（ICI）的影响（ HetCN）。提出的基于用户位置的动态功率分配（DPAUL）机制允许MC和已部署的固定/移动SC都根据用户在小区中的位置向其服务基站（BS）动态分配发射功率。本文说明了由于SC和用户的移动性而产生的动态下行链路干扰的缓解。通过在网络中引入小区用户移动性（CUM）模型来分析小区及其用户的移动性。将提出的DPAUL机制与作者的其他ICI缓解技术进行了比较：动态固定区域合作（DFRC）和动态功率分配机制（DPAM）。通过分别在MC和fSC / mSC处分配6 GHz以下和mmWave频谱，研究了网络指标“汇总”，“用户吞吐量”，“能效”和“中断概率”。
