底层频谱共享使主网络（PN）与次网络（SN）能够灵活共存，但网络间干扰仍是关键限制因素。现有缓解策略通常依赖瞬时信道状态信息（CSI），导致高信令开销。本工作提出一种基于分区的干扰管理框架，利用大规模信道统计将PN划分为干扰区域，并将次接入点（S-AP）分类为风险等级。区域级特征化使得选择性功率降低策略得以实现，同时降低协调复杂度。仿真结果证实，所提框架在分布式无蜂窝部署中保护PN的同时，保持了次网络的频谱效率（SE）。
英文摘要
Underlay spectrum sharing enables flexible coexistence between a primary network (PN) and a secondary network (SN), but inter-network interference remains a critical limiting factor. Existing mitigation strategies often rely on instantaneous channel state information (CSI), incurring high signaling overhead. This work proposes a zoning-based interference management framework that leverages large-scale channel statistics to partition the PN into interference zones and classify secondary APs (S-APs) into risk tiers. The zone-level characterization enables selective power-reduction policies with reduced coordination complexity. Simulation results confirm that the proposed framework protects the PN while preserving SN spectral efficiency (SE) in distributed cell-free deployments.
