Study for Load Distribution Method in 3GPP Ultra Dense Network

In an Ultra-Dense Network (UDN), the number of users increases dramatically, but unbalanced load balancing in a 3GPP UDN environment is inevitable due to inappropriate cell plan. This paper introduces a method for load balancing in an Ultra Dense Network. We propose a method to measure interference and to share interference information at each Mobile Station and Base Station. The first is a method that use Mobile Station and based interference information, and the second is a method that use Base Station based interference information. And through a simulation, we confirmed the proposed method could achieve higher load balancing effect than SINR based method besides the average data throughput can be enhanced by the proposed new method.
