There is a growing interest around the world in supplying cellular networks with renewable energy, e.g., solar, wind, and hydro, to reduce carbon footprints. One of the most challenging topics is how to design a reliable and efficient renewable energy powered cellular system, which consists of the energy harvesting part, the energy buffer part and the(More)
This paper analyzes the traffic of a current LTE network in China and investigates the joint optimization of content object caching and scheduling for in-radio access network (RAN) caches. Cooperative caching has been well recognized as a way of unleashing the ultimate potential of in-RAN caches, yet its feasibility is still unexplored. Moreover, content(More)
This paper studies the design of the optimal and online cross-layer transmission and energy schedulings for a full-duplex energy harvesting wireless orthogonal frequency division multiplexing (OFDM) joint transmissions. Supported by today’s power management integrated circuit, the full-duplex energy harvesting system becomes a reality, which can overcome(More)
