Abstract:The heterogeneous network (HetNet) architecture unprecedentedly reusing spectrum faces a critical challenge of interference mitigation among cells. For this goal, existing solutions successfully reaching resource orthogonality, however, impose critical assumptions of ubiquitous synchronization among all cells. Lacking of an effective network synchronization scheme, the installation of existing solutions is obstructed. This challenge motivates us to comprehensively study all-embracing solutions including two ca… Show more
