Abstract

This paper firstly presents the system structure and mathematical signal model for multi-point coordinating downlink transmission, and then gives a detailed discussion on dynamical cell-clustering strategies and scheduling utility metric in forming cooperation cluster of cells based on detected system parameters, where the user is serviced by a cluster selected from a set of clusters. Some simulation results are given to show that dynamical cell-clustering strategies are beneficial to user performance improvement owing to fairness across all the UEs comparing to static cell-clustering method.
