5. 8. Feasibility and Performance of Dynamic TDD in Dense and Ultra-Dense Wireless Access Networks

   Author : Haris Celik; Ki Won Sung; Jens Zander; Mehdi Bennis; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Informations- och kommunikationsteknik; Information and Communication Technology;

   Abstract : Meeting the seemingly never-ending increase in traffic over wireless networks presents a major challenge for future mobile network design. Given that much of the traffic is expected to be more time-varying and unpredictable, time division duplexing (TDD) is gaining increasing favorability in part thanks to its ability to better accommodate network-wide traffic variations.

6. 9. On the Performance of Dynamic TDD in Ultra-Dense Wireless Access Networks

   Author : Haris Celik; Ki Won Sung; Jens Zander; Gustav Wikström; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Informations- och kommunikationsteknik; Information and Communication Technology;

   Abstract : The appetite for wireless high-data rate services is expected to continue for many years to come and drive the need for more capacity. Ultra-dense networks (UDNs) represent a paradigm shift where each base station (BS) serves only a few user equipments (UEs). READ MORE

7. 10. Mobility Management and Localizability for Cellular Connected UAVs

   Author : Irshad Ahmad Meer; Cicek Cavdar; Mustafa Ozger; Ki Won Sung; Halim Yanikomeroglu; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Unmanned aerial vehicles; Localization; Service availability; Air-to-ground channel; Mobility; Handover; Unmanned aerial vehicles; Localization; Service availability; Air-to-ground channel; Mobility; Handover;

   Abstract : Unmanned Aerial Vehicles (UAVs) connected to cellular networks present novel challenges and opportunities in mobility management and localization, distinct from those faced by terrestrial users. This thesis presents an integrated approach, combining two key aspects essential for the integration of UAVs with cellular networks. READ MORE
