  1. 1. Beam refinement and beam tracking using Machine Learning Techniques in 5G NR RAN

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Harshal Patel; [2021]
    Nyckelord :;

    Sammanfattning : Abstract: Growing needs of communication, demands a higher data transmission rate in 5G NR. In the 3rd generation partnership project (3GPP), frames are used to schedule the data to be transferred between the cellular base station (gNB) and user equipment (UE). LÄS MER

  3. 2. Lean Beam Management for New Radio

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

    Författare :Nawanit Kumar; [2020]
    Nyckelord :5G; NR; MIMO; Beam management; CSI-RS; Technology and Engineering;

    Sammanfattning : The use of millimetre-wave frequencies in Fifth generation New Radio has lead to high path loss due to radio propagation environment. Simultaneously, high data rates is a must for current products due to high market demand. This requirement accounts for efficient tracking of the best beam for the user equipment to stay connected to it. LÄS MER

  4. 3. Optimization of 5G New Radio for Fixed Wireless Access

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Jonathan Palm; [2019]
    Nyckelord :;

    Sammanfattning : With the advent of new 5G networks, the interest in connecting house-hold to the Internet via mobile networks has increased. One such way toconnect users is using completely stationary antennas. This use-case iscalled Fixed Wireless Access (FWA) and is seen as promising, cost-efficient means of expanding internet connectivity. LÄS MER

    Sammanfattning : Long Term Evolution (LTE) known in the market as 4G LTE, it is an evolution of the GSM/UMTS standard. The overall aim of LTE was to provide a new radio access technology focusing on packet-switched data only. LTE has provided a new peak download rates, low data transfer latencies, and improved the support for mobility. LÄS MER
