This article surveys the literature over the period of the last decade on the emerging field of
self organisation as applied to wireless cellular communication networks. Self organisation …

An optimal vertical antenna tilt in a wireless access network plays a key role for coverage
and capacity in the system. The autonomous (re-) optimization of tilts bears a large saving …

Traditional manual procedures for Coverage and Capacity Optimization are complex and
time consuming due to the increasing complexity of cellular networks. This paper presents …

In future mobile communications systems, network management procedures must be
upgraded to consider user quality of experience (QoE) to deal with service diversity. In this …

The paper presents a self-organized approach for coverage and capacity optimization by
vertical antenna tilt adaptation. The approach is based on Cooperative Fuzzy Q-Learning …

Small cell is an attractive and promising technology for improving capacity in traffic hotspots
using cell densification. We consider the traffic load-balancing problem for a macro-assisted …

Despite years of physical-layer research, the capacity enhancement potential of relays is
limited by the additional spectrum required for Base Station (BS)-Relay Station (RS) links …

Network planning and optimization is a major issue for telecom carriers. An important
question is to determine angles for antenna cells to improve network coverage and capacity …

The 3D MIMO in 5G system requires adaptive and real-time adjustment of antenna azimuth
angle, downtilt and beam combination according to the user distribution, which is a powerful …

The coverage sha** and interference reduction ability of base station antenna tilt are
important tools in cellular network optimization. Through tilt changes, the coverage area of a …
