This document is related to the technical report for the study item "Study on CoMP for LTE with Non-Ideal Backhaul" [1]. The purpose of this TR is to help TSG RAN WG1 to assess the performance benefits of CoMP operation involving multiple eNBs with non-ideal backhaul and the required specification support for the inter-eNB operation. This activity involves the Radio Access work area of the 3GPP studies and has potential impacts both on the Mobile Equipment and Access Network of the 3GPP systems. This document is intended to gather all information and draw a conclusion on way forward. This document is a 'living' document, i.e. it is permanently updated and presented to TSG-RAN meetings.
