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 …

Relaying and orthogonal frequency division multiple access (OFDMA) are the accepted
technologies for emerging wireless communications standards. The activities in many …

Load balancing (LB) aims at tackling the hot-spot cell problem caused by uneven load
distribution and resources shortage. Traditional LB schemes mainly focus on the load …

A self-organizing load balancing framework is proposed in this paper. It provides self-
optimizing load balancing policies to improve adaptation and robustness of Fixed Relay …

Load balancing (LB) is an important function of the self-organizing network (SON) for coping
with the uneven load distribution to achieve higher spectrum efficiency and lower …

在蜂窝小区中, 利用用户在不同小区之间的切换实现负载均衡可以提高系统频率利用率,
减小用户中断率. 但是, 高负载小区的边缘用户切换到低负载小区时信噪比会降低 …

In the existing researches, switching users for load balancing often leads to aggressive
handovers, which may take up plenty of resource in target cells, leading to higher Call Drop …

In OFDMA networks with the frequency reuse factor equaling to one, such as LTE networks,
handover based load balance is a commonly used scheme for balancing the unevenly …

Energy is an expensive commodity in long term evolution-advanced (LTE-A) networks,
spurring a myriad of research approaches in recent years to attempt to minimize energy …

In relay enhanced cellular networks, many call requests in hot cells are blocked due to
unbalanced traffic load, and it may be more serious in the networks with multiple traffic types …
