Coverage optimization is a main challenge for small cell clusters which are considered to be a promising solution to provide seamless cellular coverage for large indoor or outdoor areas. This paper focuses on small cell cluster coverage problems and proposes both centralized and distributed self-optimization methods. Modified Particle swarm optimization (MPSO) is introduced to centralized optimization...
Due to the cooperation diversity, Coordinated Multi-Point (CoMP) transmission may potentially improve energy efficiency of cellular networks. The main purpose of this paper is to analyze this potential. By employing CoMP, there are two schemes to improve energy efficiency; one is to decrease the transmission power of base stations (CDTP) without changing cells' size and re-deploying base stations...
Small cell cluster is a new paradigm to extend the usage of small cells from residential environment to large indoor or outdoor areas. However, coverage optimization is a challenge due to the ad-hoc deployment and plug-and-play feature of small cells. This paper considers decentralized self-optimization network (SON) architecture of small cell cluster and proposes distributed coverage optimization...
