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;
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;
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 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.

10. A power optimization sub-system comprising:
-
a receiving module of a unit of a distributed antenna system, the receiving module being configured for receiving downlink signals from one or more base stations; a grouping module communicatively coupled to the receiving module, the grouping module being configured for grouping 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; and a variable gain module configured for (i) 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, (ii) providing the first set of downlink signals to a first signal path that is unaffected by the variable gain module, and (ii) providing the second set of downlink signals to a second signal path that is communicatively coupled to the variable gain module. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
