Base station operation consumes a lot of energy, a considerable amount of which can be saved by switching off base stations during low user demand (for example, at night). Base station switching (BSS) can result in loss in coverage if not performed properly. We show that coverage is closely related to scheduling via power management and that the bottleneck is typically the uplink. To save energy,...
Development of LTE networks are still largely concentrated in urban areas and did not rule out some time in the future, rural areas can also enjoy this high-speed data services. In this paper, the performance analysis of LTE network on rural area is shown. Four scenarios are used and distinguished by frequency (900 and 1800 MHz) and bandwidth (5 and 20 MHz). Based on the results, the most effective...
Curitiba is a city in south Brazil with an estimated population of 1.8 million inhabitants [3]. The teledensity in this city is over 1.2 cellular for each person and, four players, actually are working with Long Term Evolution (LTE) in the city. However, the quality of the LTE cell coverage has not yet reached the standard of the Third Generation Partnership Project (3GPP) group. Considering the growing...
Considering the diversity of the LTE traffic Qos and the variable channel coverage caused by the time-frequency two-dimensional structure, a reasonable scheduling algorithm is proposed to enable the coverage of queues as large and close as possible and guarantee traffic Qos. Simulation results show that the new algorithm can ensure the coverage of channels as large and close as possible, while meet...
