Uplink noise minimization
First Claim
1. A method of controlling uplink signal power in a distributed antenna system having a master unit and a plurality of remote units and coupled with a base station, the method comprising:
- monitoring at least one of a noise condition or uplink signal condition of the distributed antenna system including monitoring at least one remote unit and determining if the at least one remote unit is active status or mute status;
for at least one active status remote unit in the distributed antenna system, dynamically adjusting an uplink gain that is applied to uplink signals to a base station, based on the monitored condition.

Abstract
A method and apparatus for controlling uplink signal power in a distributed antenna system 10 having a master unit 22 and a plurality of remote units 14 and coupled with a base station 12 includes monitoring a noise condition of the distributed antenna system. The invention dynamically adjusts an uplink gain within the distributed antenna system 10 that is applied to uplink signals to a base station 12, based on the monitored noise condition. Monitoring the noise condition in the distributed antenna system 10 includes monitoring one or more remote units 14 of the plurality of remote units and determining if the remote unit is active status or mute status and then. The uplink gain is increased in response to a decrease in the number of remote units that are active status and decreased in response to an increase in the number of remote units that are active status.
