Figure 4From: Dynamic Resource Partitioning for Downlink Femto-to-Macro-Cell Interference AvoidanceFour apartment blocks and ten macro UEs per macro sector. Macro UEs are denoted by red dots, femto UEs by blue diamonds, HeNBs by green crosses and eNBs by filled green circles, each denoted with a number. The close-up shows a few marked macro UEs undergoing potentially severe downlink interference from nearby active femto-cells.Back to article page
