After I wrote about the 5G Icon Display back in February, I received lots of other useful and related materials, mostly from 3GPP standards delegates. Based on this updated information, I created a presentation and video called 'The 5G Icon Story'. Only recently did I realize that I didn't add it to the blog. So here it is.
And for people who are impatient and directly want to jump to the main point, it's UpperLayerIndication in SIB 2 as can be seen above.
The slides and video is embedded below.

Based on my observation with Xioami Mi Mix3 5G and Network Signal Guru, in Romania only E/// radio uses PLMN-InfoList-r15, Huawei not .

Thank you Mihai, you have lots of valuable information on your blog. I think GSMA has added upperLayerIndication-r15 just as a mechanism for showing 5G. Different vendors (network & devices) and operators use it in a way they feel right.
ReplyDeleteIn Huawei, the transmission of upperLayerIndication-r15 in SIB 2 is controlled by a parameter called "Upper Layer Indication Switch".
ReplyDeleteThank you Faisal.
