Development of 5G NR RedCap devices
Theoretical and Natural Science, 2023The subject of this paper is the RedCap technology. RedCap devices (known as Reduced Capability devices) are a new technology that is being studied by 3GPP in the R17 phase of 5G. RedCap can be defined as a lightweight version of 5G technology. The IoT application scenarios are extremely complex and diverse, and different scenarios have different ...

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 ...

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.

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 Overview and Physical Layer
2020This text deals primarily with the physical layer. However, to better understand its operation, it is helpful to stand back a bit and study, at a high level, its surrounding architecture and protocols. To this end, we review in this chapter the main architecture options for connection to the core network followed by the Radio Access Network (RAN ...

3GPP 5G NR Millimeter Wave Standards
Proceedings of the 1st ACM Workshop on Millimeter-Wave Networks and Sensing Systems 2017, 2017The cellular industry will see a drastic growth in the wireless data traffic and emergence of new services in the next few years, where the amount of data handled by wireless networks is expected to exceed 500 exabytes by 2020. The 5G cellular system is expected to meet this demand by significantly improving certain key performance indicators ...
