First Claim
Patent Images
1. A repeater comprising:
- a forward link circuitry configured to receive communication signals received at the repeater from a base station, the forward link circuitry configured to amplify a first portion of the received communication signals to transmit the amplified communication signals to mobile stations;
a repeater phone including a first input coupled to the forward link circuitry to receive a second portion of the received communication signals received at the repeater from the base station, wherein the repeater phone includes a power control circuitry configured to generate a gain control signal in response to the received second portion of the received communication signals received at the repeater from the base station, the repeater phone further including a first output configured to transmit the gain control signal;
a controller in communication with the repeater phone and a variable gain element, wherein the controller is configured to receive the gain control signal and generate information indicative of the gain control signal;
a reverse link circuitry including the variable gain element, wherein the variable gain element is configured to receive the information indicative of the gain control signal and to adjust reverse link gain of the repeater based on the information indicative of the gain control signal.

Abstract
The invention provides a mechanism for automatically setting reverse link gain or power for a repeater (120) used in a communication system (100) through the use of the reverse link power control of a built-in wireless communications device. By embedding a wireless communication device (430, 630, 700) inside the repeater and injecting reverse link signals of the embedded device into the reverse link of the repeater (124A, 124B), the gain of the repeater is maintained relatively constant. The embedded WCD can also be activated on a periodic basis to make calls and utilize reverse link power-control to calibrate or re-calibrate the gain of the repeater, making it a power-controlled repeater.
