Project RAN Evolution: CoMP Evaluation and Enhancement

In existing commercial and trial LTE networks, testing results show that the inter-cell interference is very severe. CoMP is an important feature to cope with the inter-cell interference from operators’ point of view. In this white paper, CoMP field trial testing results are shared and different enhanced CoMP schemes are compared. Moreover, a recommendation and a guideline from operators’ point of view are required to drive 3GPP to further enhance CoMP air-interface and network standardization.
