论文摘要
潜在的移动网络将是异质的多层网络，其基础站（BS）的不同类别取决于用户需求。多层网络使操作员能够通过灵活的实现增强系统容量和覆盖范围。智能反射表面（IRS）或可重新配置的智能表面（RIS）是一种新颖且破坏性的技术，包括大量具有成本效益的被动组件，每个组件都可以通过可重新配置的相位转移来智能地反映事件波或信号。这项工作的目的是最大化由微型和宏单元层组成的两层6G网络中毫米波（MMWave）载体的用户关联概率。因此，该工作分析并比较了传统和IRS辅助微基站用户协会的概率。该研究得出的是，在微电池中，IRS的部署显着增强或最大化了包括细胞边缘在内的整个覆盖区域的用户关联可能性。此外，IRS的部署减少了微基站的发射功耗，这确保了明显的能源效率。
Prospective mobile networks will be heterogeneous multi-tier networks, with different classes of base stations (BS) installed dependent on user demand. Multi-tier networks enable operators to enhance system capacity and coverage through flexible implementations. Intelligent reflecting surfaces (IRS) or reconfigurable intelligent surfaces (RIS) is a novel and disruptive technology that comprises a vast number of cost-efficient passive components, each of which can intelligently reflect the incident wave or signal with a reconfigurable phase shift. The objective of this work is to maximize the probability of user association for millimeter-wave (mmWave) carriers in a two-tier 6G network consisting of micro and macro cell tiers. Therefore, the work analyzed and compared the probability of user association for conventional and IRS-assisted micro base stations. The research derived that, the deployment of IRS in a micro cell significantly enhances or maximizes the probability of user association of the entire coverage region including the cell edge. Moreover, the deployment of IRS reduces the transmit power consumption of the micro base station which assures a notable energy efficiency.
