US 2006/0050677 A1 · System and method for minimizing guard time in a time division duplex communication system

Abstract

Disclosed is a system and method for optimizing capacity in a multi-user time division duplex (“TDD”) communication system such as a broadband wireless radio frequency communication system. More specifically the invention minimizes guard time in duplexed signals to thereby allow for higher data throughput which results in an increase in system communication capacity. Depending upon instantaneous traffic load associated with the subscribers using a particular TDD carrier, guard times may be adjusted to provide a desired level of throughput. As traffic loads demand, the order of assignment of burst periods in either or both the transmit and receive frames of a TDD carrier with respect to the subscriber systems operable thereon are adjusted to accommodate desired guard times.

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 to be implemented in said time division duplex communication environment to minimize a guard time thereof through reference to said stored propagation delay information.
