Patent ID: 8452231

Claim:
A repeater system that mediates traffic between a network transceiver and a user transceiver in a wireless communication system, the repeater system comprising: a network unit that maintains a network link with the network transceiver; a user unit that is physically separated by a distance from the network unit and that maintains a user link with the user transceiver; a two-way wireless communication pathway in the distance between the network unit and the user unit adapted to communicate signals between the network transceiver and the user transceiver in autonomous repeater hops between the network transceiver and the network unit, between the user transceiver and the user unit, and in the two-way communication pathway between the network unit and the user unit including downlink transmission from the network unit to the user unit and uplink transmission from the user unit to the network unit; and wherein both the network unit and the user unit have a detection unit, the detection unit of the network unit being adapted to detect frame timing of downlink transmissions by detecting a preamble sequence of downlink transmissions, and the detection unit of the user unit being adapted to detect frame timing of uplink transmissions by detecting a preamble sequence of uplink transmissions; and wherein the detection unit of the network unit is adapted to detect start of frame timing of a downlink asymmetric Time Division Duplex (TDD) transmission and pass the frame timing to the user unit while the frame is being delayed; and the network unit being adapted to detect a change in transmission pattern and send information to the user unit whereby both the network unit and the user unit switch to receive mode for detecting a preamble of an incoming frame.
