5G NR radio evolution is carried out with a drive from a multitude of key stakeholders from the traditional commercial cellular industry, a wide variety of industry verticals and the non-terrestrial access ecosystem. The Release-17 work program is a testament that 3GPP is committed to serving all of these key stakeholders.

A major achievement of the RAN plenary meeting was the approval of the content for Release-17 – both in terms of the list of features included and the detailed functionality within each feature. This decision addresses the work in RAN1, RAN2, and RAN3: physical layer, radio protocol and radio architecture enhancements. Further decisions will be made at RAN#88, in June next year, on the RAN4 work for Release-17.

For Release-17 the physical layer work in RAN1 will start at the beginning of next year, whilst radio protocol and architecture work in RAN2 and RAN3, respectively, will start in the 2nd quarter.

• WR waveguide system:   EIA designation (Standard US) using a WR designator to indicate the size. The designator for a size consists of the letters WR followed by numerals indicating the lowest frequency for which they were designed for use. The letters WR stand for Waveguide Rectangular.
• WG waveguide system:   RCSC Designation (Standard UK). The waveguides types are given designators which comprise the letters WG followed by one or two numerals, e.g. WG10.

Both systems are in widespread use and enable the waveguide sizes to be matched and known.

任意功率P(mW)與xdBm換算的公式如下：

{ x=10\log _{10}(P/(1\ \mathrm {mW} ))\,}

以及

{ P=(1\ \mathrm {mW} )10^{(x/10)}\,}。

例如，1毫瓦(1 mW)換算成分貝毫瓦為0dBm。1瓦特(1 Watt)換算成分貝毫瓦則為30dBm。
