WS-18: LTE in Unlicensed Bands: Potentials and Challenges

Organizers: Andrea Goldsmith (Stanford University, USA); Alireza Babaei and Jennifer Andreoli-Fang (CableLabs); Klaus Doppler (Nokia Research)

The exponential growth of mobile data traffic and the scarcity and costliness of licensed spectrum are driving mobile network operators to consider offloading at least part of their traffic onto the unlicensed spectrum. Most recently, the 3GPP is considering extending the use of LTE into the unlicensed spectrum as a seamless approach to enable traffic offload. This new approach is dubbed LTE Unlicensed (LTE-U). Compared to Wi-Fi, LTE-U offers MNOs a way to offload traffic onto the unlicensed spectrum with a technology that seamlessly integrates into their existing LTE evolved packet core (EPC). Furthermore, LTE-U promises higher throughout and spectral efficiency than Wi-Fi. However, LTE-U introduces new coexistence challenges for other technologies in the same unlicensed bands particularly for legacy Wi-Fi. The goal of this workshop is to bring together academics, researchers, and practitioners to discuss the opportunities, challenges and potential solutions for operation of LTE in the unlicensed bands.
