1 Scope p. 6
The purpose of the present document is to help the TSG RAN WG3 group to study aspects of improving CRNC access to UE measurements in preparation for a WI on this topic, as proposed in [1].
As requested by TSG-RAN, the document describes the consequences of the CRNC not having access to UE measurements in the case that the serving RNC does not match the controlling RNC, additionally it studies the complexity of the proposed solutions so that an evaluation of the incremental gain of a solution can be weighed against its additional complexity.
