Evaluating Unlicensed LTE Technologies: LAA vs LTE-U

U-LTE: Unlicensed Spectrum Utilization of LTE

Coexistence of Wi-fi and Laa-lte in Unlicensed Spectrum

ACKNOWLEDGEMENTS First and foremost, I would like to especially thank my mother, father and families, without whose guidance and support I would not be here. Besides, I would like to present my sincere gratitude to my supervisor, Dr Raghu-pathy Sivakumar. Under his guidance, I got valuable advice and encouragements. I joined in GNAN research group without much research experience. Because of Si...

Adaptive Video Streaming over LTE Unlicensed

In this paper we consider the problem of adaptive video streaming over an LTE-A network that utilizes Licensed Assisted Access (LAA) which is an instance of LTE Unlicensed. With LTE Unlicensed users of the LTE-A network opportunistically access radio resources from unlicensed and licensed carriers through Carrier Aggregation (CA). Our objective is to select the highest possible video quality fo...

Device-to-device (D2D) Meets LTE-Unlicensed

In this article, we look into how the LTE network can efficiently evolve to cater for new data services by utilizing direct communications between mobile devices and extending the direct transmissions to the unlicensed bands, i.e., device-to-device (D2D) communications in conjunction with LTE-Unlicensed. In doing so, it provides an opportunity to solve the main challenge of mutual interference ...

LTE vs. WiMAX

This paper presents the leading technologies for the next generation wireless telecommunication networks, LTE and WiMAX. Furthermore, the used modulation and multiplexing schemes such as QPSK, QAM, OFDM, OFDMA, SC-FDMA and MIMO will be shown. In addition, the network architecture and the basic characteristics of each 4G network approach will be presented. This is followed by a discussion where ...
