The performance goals of 5G are high data rate, low latency, energy saving, low cost, high system capacity and large-scale equipment connection. The first phase of the 5G specification in Release- 15 is to adapt to the early commercial deployment. The second phase of Release- 16 will be completed in April 2020 and submitted to the International Telecommunication Union (ITU) as a candidate for IMT-2020 technology.
The ITU IMT-2020 specification requires a speed of up to 20? Gbit/s can realize MIMO with wide channel bandwidth and large capacity. 3rd generation partnership project (3GPP) will submit 5G NR (New Radio) as its proposal for 5G communication standard. 5G NR may include low frequency (FR 1), lower than 6 GHz and higher frequency (FR2), higher than 24 GHz and millimeter wave range.
