1. A power management subsystem comprising:
- a measurement module configured for monitoring a utilization metric for a remote unit in a telecommunication system, wherein the utilization metric comprises data indicative of one or more terminal devices being available for communication with the remote unit; and
an optimization module configured for;
determining whether the remote unit is underutilized based on the monitored utilization metric; and
configuring the remote unit for a low-power operation in response to determining that the remote unit is underutilized to manage power consumption in the telecommunication system;
wherein the optimization module is configured for configuring the remote unit for the low-power operation by performing operations comprising;
configuring a first set of remote units including the remote unit for low-power operation during a first plurality of time periods; and
configuring a second set of remote units including the remote unit for low-power operation during a second plurality of time periods, wherein each of the first plurality of time periods alternates with a respective one of the second plurality of time periods.

Abstract
Certain aspects involve power management subsystems for a distributed antenna system (“DAS”) or other telecommunication system. The power management subsystem can include a measurement module and an optimization module. The measurement module can monitor a utilization metric for a remote unit in the DAS or other telecommunication system. The power optimization module can determine whether the remote unit is underutilized based on the monitored utilization metric. The power optimization module can configure the remote unit for a low-power operation in response to determining that the remote unit is underutilized.

7. A power management subsystem comprising:
-
a measurement module configured for monitoring a utilization metric for a remote unit in a telecommunication system, wherein the utilization metric comprises data indicative of one or more terminal devices being available for communication with the remote unit; and an optimization module configured for; determining whether the remote unit is underutilized based on the monitored utilization metric; and configuring the remote unit for a low-power operation in response to determining that the remote unit is underutilized to manage power consumption in the telecommunication system; wherein the optimization module is further configured for; identifying an additional remote unit designated for operating in a high-power mode simultaneously with the remote unit being configured for the low-power operation; determining, subsequent to configuring the remote unit for the low-power operation, that an additional utilization metric for the additional remote unit has a value greater than a threshold utilization used for determining that the remote unit is underutilized; and configuring the remote unit for a high-power operation in response to determining that the additional utilization metric has the value greater than the threshold utilization. - View Dependent Claims (8, 9, 10)
