The basic concept of carrier aggregation and the process of establishing carrier aggregaion in NR is almost same as LTE carrier aggregation. So I would not explain much of the basic concept on carrier aggregation in this note, please refer to LTE carrier aggregation page for the concept and process of establishing CA(carrier aggregation). In this page, I will only put some examples of establishing carrier aggregation in NR.
If you are already familiar with the concept of Carrier aggregation from LTE, the only thing I want you to refresh your memory is following sequence. This is how CA is established in protocol sequence and I will try to provide several examples of this establishment process in this page.
Example 01 > NR SA 2CC CA : n78 (20Mhz) + n78(20 Mhz)This example is from the log captured by Amarisoft Callbox(gNB) and UE Simulator. Overall procedure captured in this log is as follows.
