Abstract
Individualized gain control of remote uplink band paths in a remote unit in a distributed antenna system (DAS) based on combined uplink power level in the remote unit. The combined uplink power of a combined uplink communications signal in a remote unit is measured. If the combined uplink power level exceeds a defined uplink threshold power level for the remote unit, the gain is reduced for individual uplink band paths that provide a higher power contribution to the combined uplink power of combined uplink communications signal in the remote unit. This allows the initial uplink gain of the uplink band paths in a remote unit to be set higher to increase sensitivity, because the gain of the uplink band paths providing higher power contributions to the combined uplink power in the remote unit can be reduced, without reducing gain in other uplink band paths of the remote unit.
