This TR summarizes the work done under the study item "Improvement of the Multimedia Broadcast Multicast Service (MBMS) in UTRAN" by listing technical concepts addressing the objectives of the study item, analysing these technical concepts and recommending a way forward of the study item.
The objective of this study item is to analyse the feasibility and merits of potential improvement of MBMS in the Release 7 RAN specifications. It is the intention that the introduction of MBMS based on Release 6 due to these enhancements should not be delayed, and that these improvements should be able to be integrated on top of the Rel6 functionalities smoothly. The study should progress based on the current framework of Release 6 MBMS in backward compatible ways.
The potential improvements of MBMS described in this technical report are as follows:
Support for a dual receiver UE receiving simultaneously MBMS and dedicated services on separate carriers.
SFN operation of MBMS in the physical layer.
