Evaluating the capacity gains from Coordinated MultiPoint Transmission and Reception

Abstract : This paper evaluates and compares different Coordinated MultiPoint (CoMP) Joint Processing (JP) schemes. We consider the LTE-Advanced codebook-based schemes, where the serving beams are taken from a pre-determined codebook. We namely consider Single User Joint Processing (SUJP) and Multiple Users Joint Processing (MUJP) with two variants: Least Interfering Beams (MUJPLIB) andMost Interfering Beams (MUJPMIB). We follow a cross-layer approach where both PHY and MAC layers mechanisms are taken into account by a realistic system-level simulator, whereas the higher level performance is assessed by a Markovian analysis. This latter considers the coupling between the different cells and derives the flow level capacities of the different solutions. Our results show that, globally, MUJP achieves the best performance for low to medium traffic, while all JP schemes do not perform well for large loads.
