Release 15
In early 2017, the industry agreed to a plan to accelerate the 5G standardization schedule by dividing release 15 that specifies 5G into two phases:
The NSA and SA versions share the same physical layer specifications and, therefore, NSA hardware is expected to be compliant with the SA standard.
The 5G NR (New Radio) enables a significant increase in data rates due to the incorporation of new technologies, such as the massive MIMO.
Release 16
Release 16 was concluded by 3GPP in Jun/20. It goes further in detailing the 5G specifications on items like Massive MIMO, Enhanced ultra-reliable low-latency communication (eURLLC), and Cellular-vehicle-to-everything (C-V2X).
Release 17
Release 17 had its deadline postponed to 2022 due to Covid-19. It detailed items such as NR-Light for IoT, Non-Terrestrial Communication (Satellites), Use of Unlicensed/Licensed Spectrum at 60 GHz, and Positioning.
Release 18
Os releases 18, 19 and 20 will develop the specification of the 5.5G.
5G: Objectives
5G objective is to enable the following applications:
Increase capacity to lower the cost per bit of mobile broadband.
To meet these applications, 5G technology will have to enable:
It will also have to enable the existence of virtual networks (Network Slicing) in order to offer different performance and SLA characteristics for the various applications.

Frequencies
5G will use the carrier aggregation that will allow dynamic allocation of frequencies.
In addition to the current frequencies at 700 MHz 800 MHz, 900 MHz, 1700/1800 MHz, 1900/2100 MHze 2500 MHz, the following additional bands are being considered:
The use of these frequencies for 5G will be defined by ITU in 2019 (WRC 19).
