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.

Accelerated Detection Schemes for PSS in 5G-NR
2020 IEEE 3rd 5G World Forum (5GWF), 2020Future generation networks are expected to support high data rate with very low latency so as to enable key services such as massive machine type communications, internet of things (IoTs) etc. Apart from the specific requirements set by different standard bodies in fulfilling these key services, there are key enabling features and processes that need ...

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 ...

Impact of Imperfect Channel Estimation on 5G-NR
2021 IEEE International Black Sea Conference on Communications and Networking (BlackSeaCom), 2021In 5G new radio (5G-NR), newly defined channel state information reference signal (CSI-RS) and demodulated reference signal (DMRS) are used together in the front-load transmission to improve the performance of channel estimation for the Physical Downlink Shared Channel (PDSCH).

Learning based Beam Tracking in 5G NR
2020 International Conference on COMmunication Systems & NETworkS (COMSNETS), 2020We propose a beamforming framework model which contains multiple mobile users in a 5G NR setting. The base station (BS) synchronizes with the user equipment (UE) using Synchronization Signal Bursts (SSB) that are beamformed in different directions. After establishing connection with the UE and determining the UE's location, it is important to keep ...

Research on Beamforming in 5G NR Carrier Aggregation
2021 International Wireless Communications and Mobile Computing (IWCMC), 2021Carrier aggregation is one of the important areas in 5G stand-alone (SA) networking deployment plan, which is of great value for improving user experience. In 5G SA networking deployment, there are technical and implementation challenges when carrier aggregation is combined with Massive MIMO (Multiple-Input Multiple Output).
