Fig. 7From: Joint trajectory and CoMP clustering optimization in UAV-assisted cellular systems: a coalition formation game approachSum rate comparison with different sizes of clusters when \({C}_{l}^{\mathrm{BH}}=20\) Mbps and \(K=70\) users: This figure represents the sum rate versus different values of the maximum cluster size that changed from 3 to 7 for all CoMP scenarios when the number of users is 70Back to article page
