Systems and methods for efficiently utilizing spectrum in a time division duplex system are shown. In the preferred embodiment fractions of a time division duplex frame (702) are asymmetrically adjusted as forward and reverse channels (703) according to communication demands/requests. Particular groups of resources for which independent asynchronous operation would result in undesired consequences are preferably operated in lockstep to thereby avoid the undesired consequences. Accordingly, a most preferred embodiment of the present invention provides for lockstep asymmetric adaptive time division duplexing among multiple carriers of a hub and multiple node wireless communication system.

L'invention concerne des systèmes et des procédés permettant d'utiliser efficacement un spectre dans un système en mode duplex à répartition dans le temps. Selon un mode de réalisation préféré, des fractions de trame en mode duplex par répartition dans le temps sont réglées asymmétriquement sous forme de canaux aller et retour en fonction de demandes/exigences de communication. Des groupes de ressources particuliers, pour lesquels une opération asynchrone indépendante produirait des conséquences non désirées, fonctionnent de préférence de manière synchrone, ce qui évite des conséquences indésirables. En conséquence, selon un mode de réalisation idéal, l'invention produit un duplexage adaptatif asymétrique synchrone à répartition dans le temps dans plusieurs porteuses de réseau et dans un système de communications sans fil à plusieurs noeuds.
