5G New Radio

6UE Features

The 5G New Radio specification encountered the challenge of providing a unified design across all the carrier frequencies and keeping such design as optimal as possible. However, technical components had to be tailored to specific deployments where needed, like for example the choice of waveform for UL or the utilization of beams in higher carriers. Another dimension making the design more complex was the need to address all the main development cases.

All the UE functionalities used by the 3GPP 5G specifications are defined as UE features and these are being mandatory and optional, or mandatory with optional capability. These UE features are subject to UE capability signaling and are captured in TS 38.306 [49], while features that do not have capability signaling and corresponding capability definition in TS 38.306 are by definition mandatory.

In the following we are trying to give a glimpse of some of the mandatory physical layer parameters. We are keeping the parameter names as defined by the TS 38.306 [49]. While most of the parameters are applicable to both FR1 and FR2, there are situations in which parameters are applicable only to one of the frequency ranges, this is mentioned explicitly.

There is a set of mandatory without capability signaling features [50], which provide basic functionality of the UE.
