Abstract

In one embodiment, a TDD repeater system comprises: a master unit comprising separate uplink and downlink signal paths defined therein, and configured to couple in an uplink direction to a base station and in a downlink direction to at least one remote antenna unit, wherein the uplink path communicates uplink communication signals, wherein the downlink path communicates downlink communication signals; a switch configured to change direction of signal transmissions within the master unit between the uplink communication signals and the downlink communication signals; a synchronizing unit is configured to receive via the downlink signal path a clock signal from the downlink communication signals, wherein the synchronizing unit supplies a control signal to the switch corresponding to the clock signal; wherein the switch swaps the direction of signal transmissions within the master unit between the uplink communication signals and the downlink communication signals in response to the control signal.
