 UE Capability Information

 

UE Capability Information is an RRC message that UE sents to Network (in most case during initial registration process). It informs on all the details of its capabilities. As LTE release goes higher and more features are added, UE Capability Information has become the longest and most complicated Radio Message.

 

 

If the UE is in a 5G area, there are 2 ueCapabilityEnquiry sent by the NW :

1. NW to UE: ueCapabilityEnquiry : eutra, utra, geran,
   
2. UE to NW: ueCapabilityInformation
   
3. NW to UE: ueCapabilityEnquiry : nr, eutra-nr
   
4. UE to NW: ueCapabilityInformation
