Patent

CA 2663694

Space division multiple access channelization is provided that includes scheduling transmission for two or more terminals and utilizing different code offsets that correspond to different sub-trees. The transmissions can be scheduled on overlapping frequency resources for overlapping time periods on different spatial resources. The pilot code offsets provide different pilot signatures so that the pilot transmissions do not overlap. The overlapping frequency resources can partially overlap or completely overlap.

L'invention porte sur un procédé de mise en canaux à division spatiale et accès multiple consistant: à programmer la transmission de deux ou plus de deux terminaux et à utiliser les décalages de codes différents correspondant aux différents sous-arbres. Les transmissions peuvent être prévues sur des ressources de fréquence se chevauchant pendant des périodes de chevauchement de différentes ressources spatiales. Les décalages des codes de pilotes peuvent avoir différentes signatures de pilotes pour éviter le chevauchement des transmissions de pilotes. Le chevauchement des ressources de fréquence peut être partiel ou total.
