摘要: Worldwide mobile broadband communications networks are increasingly contributing to global energy consumption. In this paper we tackle the important issue of enhancing efficiency cellular without compromising coverage and users perceived Quality Service (QoS). The motivation is twofold. First, operators need reduce their operational bill. Second, there a request environmental protection from governments customers CO2 emissions due information technology. To end, in first present holistic system view design adopted EARTH (Energy Aware Radio neTworking tecHnologies) project. goal ensure that any proposed solution improve does not degrade or performance on other part system. Then, focus technical solutions related resource allocation strategies designed for increasing diversity order, robustness effectiveness wireless multi-user communication We investigate both standalone heterogeneous cells deployment scenarios. scenarios, challenge overall downlink consumption while adapting target spectral actual load meeting QoS. with different cell scales ranges macro
