The present document is intended to capture findings produced in the context of the study on optimizations of UE radio capability signalling. The study is expected to proceed as follows:

• Study the size of UE Radio Capability signaling
• Study mechanisms to optimise the UE Radio Capability signalling over the air while addressing the limitations of radio protocol interface,
  • Solutions using UE capability identity,
  • Solutions using other means (i.e. segmentation, compression).

The study shall consider the possibility to change UE radio capabilities. As part of the study and in coordination with other WGs especially RAN WGs it should be concluded whether to proceed with normative work.
