NR - The New 5G Radio-Access Technology

2018 IEEE 87th Vehicular Technology Conference (VTC Spring), 2018
This paper provides a detailed overview of the key technology features of the new 5G/NR radio-access technology, the first release of which has recently been published by 3GPP release 15, of the NR specifications finalized by the end of 2017. This first release is limited to non-standalone NR operation, implying that NR devices rely on LTE for initial ...

Research on Beamforming in 5G NR Carrier Aggregation

2021 International Wireless Communications and Mobile Computing (IWCMC), 2021
Carrier 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).

Learning based Beam Tracking in 5G NR

2020 International Conference on COMmunication Systems & NETworkS (COMSNETS), 2020
We 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 ...

Decoding Latency of LDPC Codes in 5G NR

2019 29th International Telecommunication Networks and Applications Conference (ITNAC), 2019
Fifth generation (5G) new radio (NR) is the next generation of mobile network beyond the fourth generation (4G) long term evolution (LTE). In order to meet high throughput and low latency requirements, low-density parity-check (LDPC) codes are adopted by the 5G NR standard for data channels.

A Bound on the Actual Code Rate in 5G NR

2020 International Conference on Information Networking (ICOIN), 2020
In fifth generation (5G) new radio (NR), the transport block size (TBS) is determined by using a formula. There may be a large deviation between the actual code rate and the target code rate. As a result, the radio link quality should be aligned with the actual code rate instead of the target code rate.

NR: The New 5G Radio Access Technology

IEEE Communications Standards Magazine, 2017
This article provides an overview of the technology components and capabilities of the New Radio (NR) radio interface standard currently under development by 3GPP. NR will enable new use cases, requiring further enhanced data rates, latency, coverage, capacity, and reliability.

NOMA based 5G NR for PTM Communications

2019 IEEE International Symposium on Broadband Multimedia Systems and Broadcasting (BMSB), 2019
Recent advances in broadband communications have led to the first standardization phase of 5G (Rel’ 15). Several works present this novel standard as the main solution in order to cover all the new requirements that have arisen in the multimedia delivery industry.

5G NR Cell Search and Random Access

2021
Before a UE can properly communicate within a network, it must carry out cell search to find, synchronize, and identify a cell. Then, it can acquire basic system information and perform random access to access the cell. This chapter introduces the fundamental concepts of 5G NR cell search and random access.

3GPP 5G NR Millimeter Wave Standards

Proceedings of the 1st ACM Workshop on Millimeter-Wave Networks and Sensing Systems 2017, 2017
The 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 ...
