Dynamic channel allocation in macrocells with deterministic exclusion for allowing underlaying autonomous microcells

摘要

Co-Existence Dynamic Channel Assignment (DCA) techniques for overlay macrocellular systems facilitate the coexistence of embedded autonomous underlay microcellular (e.g., indoor) systems. The co-existence of the two systems without excessive mutual interference is achieved through systematic deterministic exclusion of predefined subsets of the universal channel set from the dynamic assignment to the overlay macrocells. The sets of channels are made available to the underlay systems. The exclusion is done with minimal DCA performance degradation. Multiple deterministic exclusions methods are described.
