“…Interference problem in a cellular network has been extensively researched in literature as it has direct impact on the QoS offered by a network operator. In Long Term Evolution (LTE) and Long Term Evolution-Advanced (LTE-A) standards, Inter-Cell Interference Co-ordination (ICIC) and enhanced Inter-Cell Interference Co-ordination (eICIC) schemes are available to address this problem, but the level of precision and coordination involved between the cells makes it less viable for practical implementations [1], [8]. The best candidates for such scenarios are machine learning and automation techniques which form the basis of Self Organizing Networks (SON) for mobile environment [9][10][11].…”

Bernal Mor, E.; Pla, V.; Martínez Bauset, J.; Luis Guijarro (2016) Abstract-During the last years, mobile cellular networks have witnessed an enormous growth in the carried data-traffic volume. The current networks' features are not enough to cope with this traffic trend and the concept of small cells has emerged as a feasible solution to increase the network capacity. However, the deployment of small cells introduces several technical challenges such as the cross-tier interference between the macrocell and the small cells, or the use of the subscriber land-line to send the backhaul data. In this paper, an analytical model is proposed to study the impact that the user traffic dynamics, the mobility of macrocell users, the scheme chosen to associate macrocell users to the small cells and the changing available capacity of the small cells backhaul have on the system performance. To make the solution of the model computationally feasible, we exploit the time-scale decomposition approach. In most practical scenarios, the arrival and departure rates of traffic flows are much larger than the rate of events associated with the mobility of macrocell users. Then, flows perceive that macrocell users are still. This model is applied to identify the scheme to associate macrocell users to the small cells which maximizes the performance perceived by the small cell users.

Transmission power allocation in modern mobile telecommunication systems is one of the most important aspects affecting overall performance. Addressing this issue has huge impact on improving state-of-the-art for mobile telecommunication systems such as Long Term Evolution-Advanced by reducing inter-cell interference. To approach global optimality, some sort of cooperation between base stations is needed to overcome many shared limitations. This article proposes cooperative transmission power assignment mechanism based on the coordinated multiple points' concept. It provides mathematical treatment and technical development for the proposed solution. This solution works in distributed fashion which is one of the main strengths of our approach. The proposed transmission power mechanism adopts auction theory approach to allocate power level for each base station. The proposed solution has showed tremendous good performance in extensive simulation experiments.
