RRC ConnectionReconfiguration in DetailAs in LTE, RRC Reconfiguration is the most important steps in establishing Radio Connection between UE and Network. Understanding every details of RRC Reconfiguration would imply understanding almost everything in NR Radio Stack. I would take around an year to get the understandings on the details of this single message to a certain degree and you would need to keep learning further details and new things throughout the whole life cycles of 5G/NR. So.. don't be too hurry trying to understand everything at a time and read / think on small pieces and analyze the protocol log when available whenever you have chance. This page also will be updated piece by piece and linked to many other pages for the details.
Overall Sequence of RRC Reconfiguration for NRFollowing sequence shows what triggers NR RRC Reconfiguration on UE. As you see here, this can be triggered by LTE (in NSA(Non-Standalone) deployment) or by NR (in SA(Standalone) deployment).
Purpose (Function) of RRC ReconfigurationAs you can guess from the word itself, the major functionality of RrcReconfiguration is to setup or modify RRC configuration. This imply that there should have already been some RRC Configuration process before this message. It is true. In LTE, there is a step RrcConnectionSetup message before RrcConnectionReconfiguration and in NR there is RRC Setup message before RrcReconfiguration. The major functionality of RRC Reconfiguration are to configure following RRC Components/Functions
For each of the RRC Component/Functions, RrcReconfiguration message can do following operations
What should UE do when it gets RRCReconfiguration message ?What should a UE do when it gets RrcReconfiguration message ? The answer is simple. Do whatever the message tell you to do. I know this is not the answer you want to hear :). Like in LTE, RRCReconfiguration is the most complicated message in NR. Understanding this message in full detail is like understanding the full protocol stack of NR. You will see a good framework or starting point of understanding this message in 3GPP 38.331 - 5.3.5.3 Reception of an RRCReconfiguration by the UE. Followings are some of the highest level IE(Information Elements) that you may start with.
Since this message carries too many parameters (Information Elements), you would easily get lost if you try to go through each and every items from the beginning. I would suggest you to pick up any one of the high level items from the items listed above and try to understand the overall functionality of the high level item ,and then move to next item and get an overview and so on. When you have overall understandings on every items listed above, then move down to next level (one-step down) in each section. RRC Reconfiguration Message structureFollowings are RRC Reconfiguration Message structure from 38.331. (

< RadioBearerConfig >The radio bearer configuration process allows the network to establish, modify, and release radio bearers for the UE. the radio bearer configuration procedure allows the network to control the radio bearers used by the UE to meet the QoS and service requirements. It is a key part of RRC connection establishment, reconfiguration, and mobility procedures. Here is a brief overview of what radio bearer configuration does:
Here goes a little bit detailed summary based on 38.331-5.3.5.6 The UE performs actions to configure radio bearers based on the RadioBearerConfig IE received from the network. This includes SRB release, SRB addition/modification, DRB release, DRB addition/modification, multicast MRB release, and multicast MRB addition/modification. Followings are summary based on each sections under 38.331-5.3.5.6

The term "spCell" refers to a specific or primary cell in a defined group within a cellular network. "spCell" is used to refer to a special cell for a defined group, making it the primary cell of that particular group. It's often mentioned in the context of Master Cell Group (MCG) and Secondary Cell Group (SCG), where it denotes the primary cell of these groups. In the context of NSA, spCell is the first NR cell added as SCG(Secondary Cell Group) to LTE anchor.
