  1. 1. Lean Beam Management for New Radio

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

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

    Abstract : 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. READ MORE

  2. 2. Design and optimization of Bandwidth Part selection for massive beamforming

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Juan Guirado Lopez-Puigcerver; [2020]
    Keywords : Mobile communications; 5G; New Radio NR ; Bandwidth Part BWP ; Beamforming; MU-MIMO; Technology and Engineering;

    Abstract : In the last 30 years, a new mobile communications generation has been developed every 7 to 10 years. The last one that is currently under development is the Fifth Generation. This generation aims to fulfill a wide range of requirements for different use cases. To that end, a new radio access technology called New Radio (NR) has been developed. READ MORE

  3. 3. PLL for 5G mmWave

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Daniel Bakic; Jinzhuo Wu; [2020]
    Keywords : PLL; 5G-NR; RFIC; beamforming; 22nm FDSOI; charge pump; vco; loop filter; frequency divider; phase detector; phase noise; jitter; Technology and Engineering;

    Abstract : This paper presents research and implementation of a high frequency Integer-N phase-locked loop for digital beamforming in mobile devices. Multiple topologies investigated whereof two were implemented. The transient phase noise of the PLL is -104dB/-95dB @1MHz. The output frequency range is from 8G-10G. READ MORE
