POWER MANAGEMENT FOR REMOTE ANTENNA UNITS IN DISTRIBUTED ANTENNA SYSTEMS

摘要

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.

1. A computer-readable medium storing one or more programs, the one or more programs comprising instructions, which when executed by a remote unit controller in at least one remote unit configured to provide wireless communications and provided in a distributed communications system, cause the remote unit controller to:
receive an available power budget from a remote unit controller for at least one powered port in a remote unit provided in the distributed communications system, the remote unit 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 remote unit module; determine a device class of the at least one external power-consuming device connected to the at least one powered port; enable 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 disable 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.
