4G/LTE - RRC |

As the functionalities of LTE evolves and start interplay with other radio technologies (e.g, wlan, V2X, NR etc), the list of SIB is getting longer and longer. We first started with around 12 SIBs and now (as of Jan 2020. Release 15), the largest SIB Type number is SIB24. Followings are the whole SIB list as of now. This page is just a summary or point to each SIB with not much of the description, and I wrote separate notes for some SIBs that has critical functionalties. Follow the links in the description of each SIBs. Regarding how these SIBs are scheduled, refer to SIB scheduling page. Some of the SIBs are critical for the initial attach and should be detected/decoded before you attempt to attach to a cell. Often the contents of SIB get modified depending on the situation and UE should be able to get updated with the modified SIB based on SIB modification process.
NOTE : As readers knows, sharetechnote is a static sites with no places for you to exchange your ideas dynamically. I think it is worth visiting telecomHall where you exchange ideas other engineers and learn from each other.
