In this paper, we propose a distributed load balancing algorithm with adaptive bias adjustment for LTE/LTE-A HetNets. We have formulated the problem as a local sum utility maximization. The distributed algorithm is capable of fairly distributing the load among base stations with a minimum level of coordination. The performance of the algorithm was evaluated with a network topology subject to the conditions...
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...
Energy efficiency has become one of the key performance indicators for 5G wireless networks. Coordinated multipoint (CoMP) transmission/reception and multiinput single-output (MISO) are two technologies which can achieve higher energy efficiency in heterogeneous networks (HetNets) compared to conventional single-input single-out (SISO) systems. CoMP improves energy efficiency by joint transmission...
