Fig. 5From: Rotating cluster mechanism for coordinated heterogeneous MIMO cellular networksAverage achievable sum rate vs. K c with maximum throughput (MT) and proportionally fair (PF) scheduling metrics over the area of a macrocell in an arbitrary cluster, comparing proposed rotating clustering scheme and fixed clustering for six-cell layout, using simulated annealing scheduling and SZF-DPC precoding.
