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.
A method comprising:
A system comprising:
The system of claim 17 wherein degree of temporal overlap of the transmission of the master node and a remote node is proportional to distance between the remote node and the master node.
Non transitory media having processor readable code embodied on said media, said processor readable code for programming one or more processors to perform a method including:
Dependencies are inferred from the claim text.
