Load balancing is one of the key target of LTE Self-Optimization Network (SON). In this paper, we propose a load balancing method for LTE downlink network, namely Load Vector Minimization based Load Balancing (LVMLB) method. Load Vector (LV) is a vector whose elements are the load values of cells and sorted in descending order. The order of LVs is defined by the lexicographical order. The smaller...
Green communication has been a hot issue with the energy consumption of ICT industry continuously growing. To achieve the goal of energy saving, base station sleep schemes are extensively investigated; however, they are hard to implement in actual commercial network for the risk of losing of users. So in this paper, we try another way to improve the energy efficiency of LTE network by interworking...
As a major part of wireless network optimization, load balancing can make the BS's resource utilization more reasonable. This paper proposes a load-balancing strategy based on Coordinated Multiple Points (CoMP) transmission/reception among the Base Stations (BS). To use universally, different patterns of load-balancing based on CoMP are modeled and discussed. We define call blocking rate as the QoS...
In this paper we present an autonomous load balancing algorithm for downlink LTE network, the ripple form reference signal received power based load balancing algorithm (RF-RSRPBLBA), which mainly requires the reference signal received power (RSRP) and cell load information. In RF-RSRPBLBA, overloaded cells distribute their surplus load in a greedy manner. As a general character of greedy algorithm,...
