Abstract
In this letter, we study the performance of content caching in a heterogeneous cellular network (HetNet) consisting of fluid antenna system (FAS)-equipped mobile users (MUs) and single fixed-antenna small base stations (SBSs), distributed according to an independent homogeneous Poisson point processes (HPPP). It is assumed that the most popular contents are cached in the SBSs to serve the FAS-equipped MUs requests. To assess the performance, we derive compact expressions for the successful content delivery probability (SCDP) and the content delivery delay (CDD) using the Gauss-Laguerre quadrature. Our numerical results show that the performance of cache-enabled HetNets can be greatly improved, when the FAS is utilized at the MUs instead of traditional fixed-antenna system deployment.
