Inter-layer radio resource management for hierarchical cell structures in FRAMES project

Hierarchical cell structures (HCS) provide flexibility in handling non-homogenous traffic, but raises several problems to be efficiently deployed. We show when and how resources can be shared between layers (e.g., TDMA frame partitioning between layers). As an application of the proposed concepts, we consider the Future Radio Wideband Multiple Access System (FRAMES) and UMTS Terrestrial Radio Access (UTRA) multiple access modes. We also provide several algorithms for inter-layer resource management (handover, admission control, congestion/load control).
