Abstract

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 are asymmetrically adjusted as forward and reverse channels 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.
