Upper Layer Indication is a broadcast that may be received from a 4G tower, indicating that 5G is available. A 5G icon may appear, depending on the phone, even if 5G is actually unavailable. 5G may still work without Upper Layer Indication.

5G is not indicated.

5G is indicated.

Use of 4G with 5G restricted by subscription etc: TRUE / FALSE.

Not restricted.

Restricted.

Counts radio link failures.

Type of failure encountered.

No failure encountered.

It is a failure to decode notifications after repeated attempts. What's considered a failure is up to settings loaded from the tower.

A certain kind of error detection went through the equivalent of 'Could you repeat that? Could you repeat that? Could you repeat that?' until a set limit was reached.

Failed to connect.

Refer to Band, but note the following differences:

In 5G, the search for an important part of the signal can be fine or coarse. The raster depends on the band number, making it one of the differences in n38 vs n41 vs n90.

In 5G, a band defines minimum device capabilities, e.g. that 4Rx is required.

Then it might not be able to use 5G, regardless of its bands.

5G may operate on newer bands. Though 5G may be used for providing a short range & high capacity kind of signal, 5G does not require this. 5G may be used on waves that previously carried 4G/3G/2G (including long range & low capacity kinds of signal), which results in a slight maximum speed gain in the downlink. If a short range & high capacity signal is used, and it is set up well, users in its coverage do not slow down users outside its coverage, so the speed of both those in the short range and those not within the short range improves.

Connected discontinuous reception. While connected, reception is discontinuous if NR_CDRX: Active. Not because the signal is weak, but as a power saving measure. How discontinuous reception cycles work are up to settings, affecting latency and power savings.

Wi-Fi may, basically, be 20, 40, 80, or 160MHz wide, there are many widths 5G may be deployed on too, the width is displayed here. Note that the width may refer to a pair of channels that are not next to each other, one being for uploading, the other for downloading, or it may refer to a single channel phones and towers take turns in. The BW may be lower than 4G's maximum BW. Carriers can't freely change the BW.

Rate of 'Could you repeat that?' while transferring data. A rate of approximately 10 is okay. A rate that's too low is too cautious and counterproductive.

How the resource element grid works. More time and fewer waves (lower SCS) or less time and more waves. A wider SCS takes up more frequencies but uses less time. If there's less time, there's less time to wait out 'echoes' of the signal. If the signal tends to be short-range, there are fewer 'echoes', so a higher value can be used. Short-range kinds of signal get high values, long-range kinds of signal get low values. 15 is the only option in 4G. Raising the value does not improve speeds, but may improve the latency.

Similar to CA, but with 5G instead.

DSS is where 5G operates inside 4G.
