As can be seen in RP-111377 the study item was approved in September 2011. The working group with the primary responsibility was RAN3, the secondary one was RAN1 for the study of the impacts on the physical layer.

In RAN#57 (September 2012), RAN3 concluded its study for the architecture aspect. As the result, the overall completion level was estimated at 80% (100% completion for RAN3, 0% for RAN1).

This overall completion level remained stable from September 2012 to September 2014 where it was decided to close the work item.

Due to the work load in RAN1, RAN plenary meeting postponed several times the work on this study item (see for example RP-130133 section 1.2.2 : “This SI will not be treated in RAN1 in 2013 Q1, as decided by RAN#58.”). Similar statements can be found in next status reports until it was decided to close the study item.

This is reflected in the conclusion of the Technical Report associated with this study item: TR 36.836:

 

RAN3 selected Alt.1 and Alt.2 for further work on mobile relays.

The physical layer aspects related to mobile relay have not been studied in the Study Item.
