Rapporteur:  Dr. Kim, Laeyoung

The objective of this Technical Report is to identify and evaluate potential architecture enhancements of EPS and 5G System design needed to support advanced V2X services identified in TR 22.886, based on vehicular services requirements defined in TS 22.185 and TS 22.186 and determine which of the solutions can proceed to normative specifications.
