Abstract

This paper aims to provide a simple greedy solution for a user-centric clustering scheme in the joint precoding problem for indoor RIS-aided cell-free scenarios, where each user is matched with a group of APs and a group of RISs. For this, a non-convex joint precoding problem is solved following methods available in the literature, where we add a two-timescale approach for clustering formation and investigate its impacts on signaling overhead.
