Abstract
Background. Deploying of 5G mobile networks opens up wide opportunities for the development of IoT, high-speed access to Internet services, industrial automation, telemedicine and other modern services. Peak transmission rate, latency, and spectral efficiency are important indicators for network performance. These indicators are primarily determined by the 5G-NR radio subsystem, which is built using modern technologies such as OFDM, interference-resistant LDPC coding and massive MIMO antenna systems. In addition, frames and time-frequency resource distribution in 5G-NR are improved for both Downlink and Uplink. All of these are described in various 3GPPP documents, but to evaluate these indicators, it is necessary to create an appropriate methodology and perform calculations.
 Objective. The purpose of the research is to create a methodology and estimate the potential values of peak transmission rate, latency and spectral efficiency of 5G-NR radio channels.
 Method. Analytical calculation methods based on recommendations and source data of 3GPP documents are used.
 Results. Analytical studies show that 5G-NR radio channels can potentially provide a peak transmission up to 37 Gbps, latency less than 0.5ms, and spectral efficiency up to 46 bps/Hz rate in the Downlink direction using 50 MHz FR1 frequency band, QAM256 modulation and MIMO 8 x 8-antenna system.
 Conclusions. The researched 5G-NR radio channels efficiency indicators meet current and future services requirements.
