摘要

LTE Femtocell network categorized as small cell technology will play an important role in the future 5G networks owing to the fact that it cannot only expand the coverage of wireless communication systems but it can also increase frequency reuse. As the times of Internet of thing” (IOT) is coming, the data volume will be explosive tremendously in the future. Hence the need to deploy femtocell is stringent. However, the growing deployments of femtocell base stations (FBSs) have brought a serious issue of inter-FBS interferences (also referred to as co-tier interference) due to their easy and convenient installation. In this article, we propose a systematic approach to reduce FBS co-tier downlink interference under the scenario that FBSs are densely deployed in an environment. Power control for FBS is performed when the number of warning messages issued from Femtocell User Equipment (FUE) is greater than a threshold for a typical distributed power control scheme. However, it will reduce the SINR of its served FUEs; therefore reducing the total capacity. In our proposed LAGPC scheme, A FBS performs power control only when the number of FUEs connected to other FBSs interfered by itself is greater than that of its served FUEs. Our proposed scheme has been validated through simulations that it could effectively reduce co-tier downlink interference in shared-spectrum femtocell environments, thereby boosting system performance by 40% on average.
