Power management for remote antenna units in distributed antenna systems
First Claim
1. A method of operating a remote unit in a wireless communications system, the method comprising:
- receiving downlink optical communications signals at the remote unit;
receiving an available power budget for at least one powered port configured to provide power to at least one power-consuming device connected to the at least one powered port based on power required by at least one power-consuming remote unit module;
determining a device class of the at least one power-consuming device connected to the at least one powered port;
enabling power for the at least one powered port if the available power budget is sufficient to power the at least one power-consuming device of the device class connected to the at least one powered port;
disabling power for the at least one powered port if the available power budget is not sufficient to power the at least one power-consuming device of the device class; and
transmitting radio frequency (RF) downlink signals into a coverage area.

Abstract
Power management for a remote antenna unit(s) (RAUs) in a distributed antenna system. Power can be managed for an RAU configured to power modules and devices that may require more power to operate than power available to the RAU. For example, the RAU may be configured to include power-consuming RAU modules to provide distributed antenna system-related services. As another example, the RAU may be configured to provide power through powered ports in the RAU to power-consuming devices. Depending on the configuration of the RAU, the power-consuming RAU modules and/or power-consuming devices may demand more power than is available at the RAU. In this instance, the power available at the RAU can be distributed to the power-consuming modules and devices based on the priority of services desired to be provided by the RAU.
