A Successful Transmission Probability Based AP Clustering Scheme in User-Centric Cell-Free Networks
文献摘要：
Cell-free network is a promising archi-tecture with numerous merits in energy efficiency and macro diversity,which is easy and flexible to integrate with other communication technologies.However,its current network topology where access points(APs)are connected to a central processing unit(CPU)to jointly serve the users,causes huge burden to the fron-thaul network.To deal with this problem,in this paper,we first combine thoughts in user-centric(UC)net-work where users are served by selected subset of APs.Then,we propose a successful transmission proba-bility(STP)based AP clustering scheme to reduce the fronthaul capacity requirement(FCR).By using stochastic geometry and proper approximation meth-ods,the approximated STP calculation expression is derived.Numerical simulations demonstrate that the obtained STP expression can provide a tight approx-imation compared to Monte Carlo simulation results under different system parameters while keeping the computation tractable.Furthermore,the relationship between the FCR and the STP threshold is formulated as a clustering optimization problem,which gives in-sights on clustering design in UC-CF network sys-tems.We show by simulation results that the pro-posed scheme requires less fronthaul capacity than the original CF approach while ensuring the STP perfor-mance.
