  1. 1. Digital Front End Algorithms for Sub-Band Full Duplex

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

    Författare :Midhat Rizvi; Khaled Al-Khateeb; [2023]
    Nyckelord :Adjacent Channel Leakage Ratio; Bit Error Rate; Clipping and Filtering; Crest Factor Reduction; Digital front end; Digital Pre-Distortion Error Vector Magnitude; Frequency Division Duplex; Power Amplifier; Peak to Average Power Ratio; Peak Cancellation Crest Factor Reduction; Sub Band Full Duplex; Self-Interference Cancellation; Signal-to-Interference Noise Ratio; Signal-to-Noise Ratio; Turbo Clipping; Time Division Duplex; Technology and Engineering;

    Sammanfattning : Sub-band full duplex is a new communication scheme technology, where a single frequency band is partitioned into sub-bands for downlink (DL) and up-link(UL) transmissions, and both can take place simultaneously. The idea behind the sub-band full duplex development is to improve the throughput, and coverage and reduce the latency of the UL communication by allowing the UL reception during the DL transmission.

  3. 2. Machine Learning assisted gNodeB Data Link Layer Capacity Management

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :Adam Axelsson; [2023]
    Nyckelord :machine learning; telecommunications; 5g; packet losses; pacing algorithm;

    Sammanfattning : In the uplink direction of 5G New Radio, signals are sent between Ra-dio Units and Digital Units. The production of these signals is non-deterministic, leading to signals often being produced in bursts. Thesesignal bursts can lead to exceeding the Data Link Layer capacity, whichcauses packet losses. LÄS MER

    Sammanfattning : The Radio Access Network (RAN) plays a vital role in enabling mobile network connectivity using radio waves. Gaining a comprehensive understanding of RAN applications is crucial, and trace analysis provides valuable insights into their operations. LÄS MER

  5. 4. Link Adaptation in 5G Networks : Reinforcement Learning Framework based Approach

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

    Författare :Siva Satya Sri Ganesh Seeram; [2022]
    Nyckelord :Link Adaptation; OLLA; AMC; Reinforcement Learning; DDPG; BLER; Länkanpassning; OLLA; AMC; förstärkningsinlärning; DDPG; BLER;

    Sammanfattning : Link Adaptation is a core feature introduced in gNodeB (gNB) for Adaptive Modulation and Coding (AMC) scheme in new generation cellular networks. The main purpose of this is to correct the estimated Signal-to-Interference-plus-Noise ratio (SINR) at gNB and select the appropriate Modulation and Coding Scheme (MCS) so the User Equipment (UE) can decode the data successfully.

  7. 5. Beamforming router as relay to increase 5G cell coverage

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Jhansi Dunuka; Nikolai Panagiotou; [2021]
    Nyckelord :Beamforming; MIMO; 5G; NR; Direction of Arrival; Relay;

    Sammanfattning : The growing traffic and global bandwidth shortage for broadband cellular communi-cation networks has motivated to explore the underutilized millimeter wave frequencyspectrum for future communications. Fifth generation (5G) is the key to empow-ering new services and use cases for people, businesses, and society at large. LÄS MER
