论文摘要
本文开发了一个随机几何框架，以表征共存Terahertz（THZ）和射频（RF）网络中典型用户的下行干扰和覆盖概率的统计信息。我们首先表征了仅THZ网络中用户的骨料干扰和覆盖概率的确切拉普拉斯变换（LT）。然后，对于共存的RF/THZ网络，我们将考虑偏置接收的信号功率关联（BRSP）的典型用户的覆盖率概率。可以定制该框架以捕获各种网络配置中典型用户的性能，例如仅THZ，机会性RF/THZ和Hybrid RF/THZ。另外，对于THZ BSS的强度变大或在THZ接近零的情况下，提出了渐近近似值。数值结果证明了与共存网络中传统的参考信号接收能力（RSRP）关联相比，与BRSP关联的重要性相关的派生表达式和提取见解的准确性。
This paper develops a stochastic geometry framework to characterize the statistics of the downlink interference and coverage probability of a typical user in a coexisting terahertz (THz) and radio frequency (RF) network. We first characterize the exact Laplace Transform (LT) of the aggregate interference and coverage probability of a user in a THz-only network. Then, for a coexisting RF/THz network, we derive the coverage probability of a typical user considering biased received signal power association (BRSP). The framework can be customized to capture the performance of a typical user in various network configurations such as THz-only, opportunistic RF/THz, and hybrid RF/THz. In addition, asymptotic approximations are presented for scenarios where the intensity of THz BSs becomes large or molecular absorption coefficient in THz approaches to zero. Numerical results demonstrate the accuracy of the derived expressions and extract insights related to the significance of the BRSP association compared to the conventional reference signal received power (RSRP) association in the coexisting network.
