Abstract
A method and system are provided for adjusting power distribution to remote radio heads in a telecommunication network. Multiple buses are implemented in a configuration to individually distribute power to remote radio heads. Each bus is connected to a remote radio heads allowing the remote radio head to receive power on an individual basis and different from other remote radio heads. An eNodeB collects operational measurements from a cell site which are used to provide instructions to adjust the power to each bus and corresponding remote radio head.

A method for adjusting power distribution to remote radio heads in a telecommunication network, comprising:
- connecting each unique power bus to each remote radio head, wherein each remote radio head transmits in a sector in a cell site and is a member of a group of remote radio heads assigned to the cell site, and wherein each unique power bus is a member of a group of power buses;
- connecting the group of power buses to a power distribution unit;
- receiving direct current (DC) power into the group of power buses;
- and
- changing the DC power to each unique power bus, where each unique power bus is respectively connected to each remote radio head, and wherein the DC power provided to a first remote radio head is different from the DC power provided to a second remote radio head.
A system for adjusting power distribution to remote radio heads in a telecommunication network, comprising:
- a power distribution unit operable to receive direct current (DC) power from a set of batteries or rectifier when there is a loss of alternating current (AC) power;
- the power distribution unit transmits the DC power to a set of power buses where each power bus is connected to a unique remote radio head, wherein a set of remote radio heads are assigned to a cell site and each remote radio head covers a cell site sector for wireless transmission;
- and
- the power distribution unit individually alters a portion of the DC power to each power bus in the set of power buses and causes a change in the portion of the DC power received at each unique remote radio head.
A system for adjusting power distribution to remote radio heads in a telecommunication network, comprising:
- a power bus connects to a remote radio head, wherein the remote radio head transmits in a sector in a cell site and is a member of a group of remote radio heads assigned to the cell site, and wherein the power bus is a member of a group of power buses;
- the group of power buses connects to a power distribution unit and receives direct current (DC) power;
- and
- the power bus receives a change in the DC power, wherein the power bus in the group of power buses is respectively connected to the remote radio head in the group of remote radio heads, and wherein the DC power provided to a first remote radio head is different from the DC power provided to a second remote radio head.
