Summary:In the context of long term evolution (LTE) Advanced networks so called coordinated multi point transmission (CoMP) - where transmission is done jointly from several cells to user equipment (UE) - has gained a lot of interest lately. To benefit from CoMP by interference mitigation, UEs have to be served user centric to really leverage potential performance gains like increased capacity or spectral efficiency. This leads to a severe challenge how to assign user groups (UG) to cooperation areas (CA) in a user centric way because UGs must be found with an unique set of strongest cells. Here the so called partial CoMP concept is proposed and analyzed, which allows to serve up to 90% of all UEs in a user centric manner by their 3 strongest cells. The main achievement is to reach the significant performance gains of user centric cooperation for a practical and easy to realize system.
