O-RAN for Energy-Efficient Serving Cluster Formulation in User-Centric Cell-Free MMIMO
<|reference_start|>O-RAN for Energy-Efficient Serving Cluster Formulation in User-Centric Cell-Free MMIMO: The 6G Massive Multiple-Input Multiple-Output (MMIMO) networks can follow the so-called User-Centric Cell-Free (UCCF) architecture, where a single user is served by multiple Access Points (APs) coordinated by the Central Processing Unit (CPU). In this paper, we propose how O-RAN functionalities, i.e., rApp-xApp pair, can be used for energy-efficient Serving Cluster Formulation (SCF). Simulation studies show up to 37\% gain in Energy Efficiency (EE) of the proposed solution over the state-of-the-art Network-Centric (NC) designs.<|reference_end|>
