Systems and methods are presented that offer significant improvements in the performance of time division duplex (TDD) systems by utilizing an adaptive synchronous protocol. Conventional TDD systems are limited because data is transmitted during discreet and limited intervals of time, and because TDD transceivers may not simultaneously transmit and receive for reasons of insufficiently separated frequencies and limited receiver selectivity. Typically, TDD systems have significant latency due to the time to change from transmission to reception and the propagation delay time. By synchronizing the master nodes and the one or more remotes and by scheduling the traffic loads between these nodes, remote nodes may begin transmitting before the master node is finished with its transmission, and vice versa. This method reduces latency and improves the frame efficiency. Further, the frame efficiency may improve as the distance from the master node to the remote node increases. |

1. A method comprising:
transmitting from a master node to one or more remote nodes, a synchronization signal, said synchronization signal operable to cause the one or more remote nodes to transmit according to a predetermined timing; receiving at the master node a response to the synchronization signal, said response providing propagation time information; generating schedule information, said schedule information effectuating a desired frame efficiency, and transmitting, from the master node to the remote nodes, the schedule information, wherein at least one of the remote nodes to transmit information to the master node while the master node is transmitting on substantially the same channel. |
