    Abstract: A method of controlling gains within a repeater may include determining a power control set point value which controls a transmit power of a mobile station (MS) and receiving a downlink signal from a base station transceiver system (BTS). The method may further include measuring a power of the received downlink signal and computing a power level of a signal expected at the uplink of the repeater wherein the computing is based on the measured downlink power and the power control set point value. Finally the method may further include adjusting a gain of at least one amplifier based on the computed power level. An apparatus for controlling gains in a repeater may include a baseband processor for performing the above method.

    Abstract: In one embodiment, a device for constructing a pilot signal for use in a wireless repeater where the pilot signal is added to a transmit signal includes one or more pilot generators. Each pilot generator generates a carrier pilot signal associated with a single carrier of the transmit signal and the carrier pilot signals generated by the one or more pilot generators are summed to generate the pilot signal. Each of the one or more pilot generators includes a pilot symbol unit providing multiple data symbols having a predetermined data structure as the carrier pilot signal, a pilot scrambler, a filter, a pilot power determination unit, and a cyclic prefix insertion unit for inserting a cyclic prefix to the carrier pilot signal. In another embodiment, the pilot symbol unit providing multiple data symbols in frequency domain as the carrier pilot signal.
