本研究分析了当多输入多输出（MIMO）主网络（PN）与分布式MIMO（D-MIMO）次网络（SN）均在时分双工（TDD）模式下运行且其上行（UL）和下行（DL）阶段不同步时，两者之间的共存问题。当网络采用不同的3GPP时隙模式（这些模式在UL/DL比例和时隙位置方面有所不同）运行时，观察到了干扰的影响，这对它们的整体频谱效率（SE）产生了显著影响。鉴于此，我们提出了一种时隙模式协调方法，通过控制SN所用模式的特征来减少PN网络感知到的干扰。结果表明，该策略有助于避免PN性能的损失。
英文摘要
In this study, the coexistence between a multiple-input and multiple-output (MIMO) primary network (PN) and a distributed MIMO (D-MIMO) secondary network (SN) is analyzed when both networks operate in time division duplex (TDD) and their uplink (UL) and downlink (DL) phases are not synchronized. The impact of the interference is observed when the networks operate with different 3GPP slot patterns, which vary in terms of UL/DL proportion and slot position, resulting in a significant impact on their overall spectral efficiency (SE). Given that, we propose a slot pattern coordination to reduce the perceived interference on the PN network by controlling the features of the pattern used by the SN. The results show that this strategy helps to avoid loss of performance at the PN.
