Abstract:
1. A system for controlling scheduling of information communication in a time division duplex communication environment, said system comprising: a memory storing propagation delay information for a plurality of nodes in communication with a hub; and a controller in communication with said memory and operable under control of an instruction set to determine a time slot assignment having a determination of an order of ones of said plurality of nodes to be provided communications in a communications frame, said time slot assignment to be implemented in said time division duplex communication environment to minimize a guard time thereof through reference to said stored propagation delay information, and said order of ones of said plurality of nodes is determined at least in part from a hierarchy of said stored propagation delay information, wherein minimization of said guard time by said controller includes determining said timeslot assignment based at least in part on the greatest of a first guard time determined from a propagation delay associated with a first node of said determined order and guard times determined from a propagation delay minus the sum of any preceding time slot durations associated with each succeeding nodes of said determined order.
