Optimizing power allocation in signal distribution systems using variable and static gains
First Claim
1. A method comprising:
- receiving, by a unit of a distributed antenna system, downlink signals from one or more base stations;
determining, for each downlink signal, whether applying a variable gain or a static gain to the downlink signal would provide more effective coverage in the distributed antenna system;
grouping, by the unit, the downlink signals into a first set of downlink signals to apply a static gain and a second set of downlink signals to apply a variable gain, based on the results of the determinations as to whether applying a variable gain or a static gain would provide more effective coverage;
applying the static gain to the first set of downlink signals;
determining a gain for at least some signals from the second set of downlink signals that is sufficient to achieve a specified metric indicative of a performance level of the distributed antenna system; and
applying the determined gain to the at least some signals from the second set of downlink signals.

Abstract
Systems and methods are provided for optimizing power allocation in distributed antenna systems and other signal distribution systems using variable and static gains. A power optimization sub-system can receive downlink signals from one or more base stations. The power optimization sub-system can group the downlink signals into a first set of downlink signals for which a static gain is to be applied and a second set of downlink signals for which a variable gain is to be applied. The power optimization sub-system can determine a gain for at least some of the signals to which a variable gain is to be applied. The determined gain can be sufficient to achieve a target metric. The power optimization sub-system can apply the static gain to the first set of signals and apply the determined gain to the second set of signals.
