    Författare :Viktor Minchev Pankov; [2020]
    Nyckelord :;

    Sammanfattning : Positioning technologies are starting to play an important role in commercial,industrial, and civil applications. Emergency caller ID and positioning in industrialenvironments are important use cases. LÄS MER

  3. 22. Reinforcement Learning for Link Adaptation in 5G-NR Networks

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Evagoras Makridis; [2020]
    Nyckelord :;

    Sammanfattning : The Adaptive Modulation and Coding (AMC) scheme in the link adaptation is a core feature in the current cellular networks. In particular, based on Channel Quality Indicator (CQI) measurements that are computed from the Signal-to-Interference-plus-Noise Ratio (SINR) level of User Equipment (UE), the base station (e.g. LÄS MER

  4. 23. Improved Precision Time Protocol with Relative Clock Phase Information

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Avneesh Vyas; [2020]
    Nyckelord :;

    Sammanfattning : A common time reference among nodes is one of the key requirements in telecommunication, distributed control systems and industrial automation systems. For instance, 3GPP LTE TDD standard requires at least ± 1.5 µsec time accuracy among base stations in order to resolve uplink and downlink transmission. LÄS MER

  5. 24. Deployment Strategies for High Accuracy and Availability Indoor Positioning with 5G

    Master-uppsats, Linköpings universitet/Reglerteknik

    Sammanfattning : Indoor positioning is desired in many areas for various reasons, such as positioning products in industrial environments, hospital equipment or firefighters inside a building on fire. One even tougher situation where indoor positioning can be useful is locating a specific object on a shelf in a commercial setting. LÄS MER

  7. 25. Investigation on Positioning Techniques for Indoor Office Scenario

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Yan Shu; Yujie Zhang; [2020]
    Nyckelord :Technology and Engineering;

    Sammanfattning : This master thesis aims to investigate downlink positioning techniques and improve fifth-generation (5G) cellular positioning performance in the indoor office scenario. In the thesis work, we target in the indoor office scenario because it is a typical deployment scenario standardized in 3GPP release 16. LÄS MER
