Coordinated multi-point (CoMP) transmission and reception was first introduced in 3GPP Rel-11and enhanced during the following releases. It is considered as a tool to improve the coverage of high data rates, the cell-edge throughput, and also to increase system throughput.
Inter-eNB support for CoMP based on X2 signaling was introduced in 3GPP Rel-12 and Rel-13. The preceding studies [3, 4] dealt with operability of CoMP itself based on the assumption that the CoMP cooperating sets (CoMP sets), determining the coordination areas, are determined and established as such. This study therefore addresses the question of creation of CoMP sets and management of these sets based on user and network traffic (including signalling) conditions.
This Technical Report covers the outcome of the study item "Study on SON for eCoMP for LTE" .
The present document provides use-case descriptions, possible solutions relative to the described use cases, and analysis of these solutions. The document is intended to gather all information and draw a conclusion on way forward.
This activity involves the Radio Access work area of the 3GPP studies and has potential impact on the E-UTRAN.
