Fig. 6From: Energy-efficient transmission strategies for CoMP downlink—overview, extension, and numerical comparisonAveraged EE versus transmit power budget Pb. For SWEE and WPEE schemes, we use two sets of priority parameters, i.e., ω1=[0.7,0.5,0.3] and ω2=[0.3,0.5,0.7]. a Sum EE. b Maximum EE. c Minimum EE. d Fairness indexBack to article page
