A Two-stage RRH Clustering Mechanism in 5G Heterogeneous C-RAN
Résumé
Cloud Radio Access Network (Cloud RAN) is one of the most promising mobile architectures for 5G networks. The basic concept of Cloud RAN is to separate the digital baseband processing units (BBUs) of conventional cell sites, from the Remote Radio Heads (RRHs), and virtualize their functions in the cloud for centralized signal processing and management. In conventional RAN architectures, one BBU is assigned to one RRH in order to maximize network capacity. However, Cloud RAN may establish a one to many logical mapping, so as to enhance network energy efficiency. This paper addresses RRH clustering problem in heterogeneous C-RAN. The proposed clustering mechanism aims to reduce network power consumption, without compromising user QoS (Quality of Service).
