Power management for remote antenna units in distributed antenna systems
First Claim
1. A wireless communication system, comprising:
- a plurality of remote antenna units (RAU), each RAU comprising a radio frequency (RF) communications module having at least one antenna configured to provide RF communications services to a coverage area,wherein at least one of the RAUs is configured to provide power to at least one external power-consuming device connected to at least one powered port; and
a head-end unit (HEU) comprising a remote controller communicatively coupled to the plurality of RAUs, wherein the remote controller is configured to;
communicate with the at least one RAU to determine an available power budget for the at least one powered port; and
communicate the available power budget for the at least one powered port in the at least one RAU to the at least one RAU.

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 external power-consuming devices. Depending on the configuration of the RAU, the power-consuming RAU modules and/or external 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.

9. A method of managing power consumed at a remote antenna unit (RAU) in a wireless communication system comprising a plurality of RAUs, the method comprising:
-
receiving an available power budget for at least one powered port configured to provide power to at least one external power-consuming device connected to the at least one powered port based on power required by at least one power-consuming RAU module; enabling power for the at least one powered port if the available power budget is sufficient to power the at least one external power-consuming device connected to the at least one powered port; and disabling the at least one powered port if the available power budget is not sufficient to power the at least one external power-consuming device connected to the at least one powered port. - View Dependent Claims (10, 11)

12. A method of managing power consumed at a remote antenna unit (RAU) in a wireless communication system, the method comprising:
-
receiving an available power budget for at least one powered port configured to provide power to at least one external power-consuming device connected to the at least one powered port based on power required by at least one power-consuming RAU module; determining a device class of the at least one external 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 external power-consuming device of the device class connected to the at least one powered port; and disabling power for the at least one powered port if the available power budget is not sufficient to power the at least one external power-consuming device of the device class. - View Dependent Claims (13)
