Implementing 5G NR Features in FPGA
2018 European Conference on Networks and Communications (EuCNC), 2018A set of physical layer features defined in the 3GPP 38 series standards (5G) were implemented in commercial off the shelf SDR products. The system created an over-the-air link operating at 3.5GHz, having 40MHz channel width and using 256QAM. The PHY layer was executed in the FPGA of the SDR transceiver; higher layers executed in the host PC ...

Historically, the main driver for location-based services has been requirements from regulatory authorities (e.g. emergency caller location requirements). However, today, many public and private entities demand delivery of location information to enable commercially motivated location-based services, which often require higher location accuracy and ...

Non-Linear Precoding for 5G NR
2018 IEEE Conference on Standards for Communications and Networking (CSCN), 2018Non-linear precoding gained attention recently in 3GPP (the third generation partnership project) as a possible technique to improve the performance of multi-user multiple input multiple output (MIMO). In this paper, research and standardization activities related non-linear precoding for 3GPP are described.

5G NR PDCCH: Design and Performance
2018 IEEE 5G World Forum (5GWF), 2018This paper analyzes physical downlink control channel (PDCCH) for 5G New Radio (NR) technology defined as part of Rel-15 3GPP physical layer specifications. The particular combination of design elements makes NR PDCCH unique compared to the PDCCH or EPDCCH designs in LTE.

Cost of Increased Bandwidth Efficiency in 5G NR
2017 IEEE 86th Vehicular Technology Conference (VTC-Fall), 2017In this paper, subband filtered CP-OFDM and windowed CP-OFDM waveforms proposed for 5G new radio (NR) are compared to LTE-like downlink and uplink waveforms under different power amplifier (PA) models. The effects of subband filtering or windowing are evaluated in terms of out-of-band and inband emissions, average error vector magnitude (EVM) and ...

Learning based Network Adaptation in 5G NR
2019 11th International Conference on Communication Systems & Networks (COMSNETS), 2019In this paper, we propose a novel terrain sensing algorithm which helps the user traversing across various terrains to adapt its connectivity to the network. For example, this algorithm enables dynamic switching between Sub-6 GHz (FR1) and mmWave (FR2) in 5G NR Networks.
