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.
Techniques d'affection dynamique de canaux (DCA) en coexistence pour systèmes macrocellulaires sans fil, facilitant la coexistence de systèmes microcellulaires autonomes intégrés (p. ex. d'intérieur). La coexistence des deux systèmes sans brouillage mutuel excessif est obtenue par exclusion déterministe systématique de sous-ensembles prédéfinis de l'ensemble de canaux de référence, par rapport à l'affectation dynamique aux macrocellules. Les ensembles de canaux sont mis à la disposition des systèmes microcellulaires. L'exclusion est effectuée avec une dégradation minimale de la performance DCA. De nombreuses méthodes d'exclusion déterministe sont présentées.
