ADJUSTING REPEATER GAINS BASED UPON RECEIVED DOWNLINK POWER LEVEL
First Claim
1. A method of controlling gains within a repeater, comprising:
- determining a power control set point value which controls a transmit power of a mobile station (MS);
receiving a downlink signal from a base station transceiver system (BTS);
measuring a power of the received downlink signal;
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; and
adjusting a gain of at least one amplifier based on the computed power level.

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.
