  1. 1. LEO Satellite Connectivity for flying vehicles

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Jinxuan Chen; [2023]
    Keywords : LEO satellite network; satellite connectivity strategy; Nash-SAC; flying vehicles; LEO:s satellitnät; Strategi för satellitanslutning; Nash-SAC; flygande fordon;

    Abstract : Compared with the terrestrial network (TN), which can only support limited covered areas, satellite communication (SC) can provide global coverage and high survivability in case of an emergency like an earthquake. Especially low-earth orbit (LEO) satellites, as a promising technology, which is integral to achieving the goal of global seamless coverage and reliable communication, catering to 6G’s communication requirements.

  3. 2. Performance and optimization of mobility between terrestrial networks and non-terrestrial networks

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Gabriel Lorentzson; [2022]
    Keywords : Non-terrestrial networks; mobility performance; handover; 5G in space;

    Abstract : The 3rd generation partnership program (3GPP) has in recent years started working on integratingnon-terrestrial networks (NTN) into the 5G eco-system. This thesis focuses on the mobility between NTN and TN, which is of great importance if 5G NTN is to provide seamless and limitless connectivity. READ MORE

  4. 3. Reinforcement Learning-based Handover in Millimeter-wave Networks

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Jiarui Yang; [2021]
    Keywords : Wireless communications; mmWave networks; reinforcement learning; handover; Trådlös kommunikation; mmWave-nätverk; Reinforcement Learning; överlämning;

    Abstract : Millimeter Wave (mmWave) is a key technology to meet the challenge of data rates and the lack of bandwidth in sub-6GHz networks. Due to a high operation frequency, the mmWave network has unique channel characteristics and a relatively high pathloss. READ MORE

  5. 4. Reinforcement Learning for 5G Handover

    University essay from Linköpings universitet/Statistik och maskininlärning

    Author : Maxime Bonneau; [2017]
    Keywords : ;

    Abstract : The development of the 5G network is in progress, and one part of the process that needs to be optimised is the handover. This operation, consisting of changing the base station (BS) providing data to a user equipment (UE), needs to be efficient enough to be a seamless operation. READ MORE

  6. 5. Energy-efficient enhancements for IEEE 802.11 WLANs : On the way to enable Cellular/Wi-Fi networks interworking

    University essay from KTH/Radio Systems Laboratory (RS Lab)
