Abstract
Abstract A method and apparatus for assigning communication resources for at least one communication site in a time division communication system having multiple reuse patterns in the time domain. A first plurality of communication sites communicate using a first portion of a time frame corresponding to a first reuse pattern. A second plurality of communication sites communicate using a second portion of said time frame corresponding to a second reuse pattern.
