Adaptive battery power distribution to remote radio heads in long term evolution (LTE) networks
View Patent ↗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.
1. 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.
2. The method of claim 1 , wherein connecting the group of power buses to the power distribution unit comprises integrating the group of power buses into the power distribution unit.
3. The method of claim 2 , wherein receiving the DC power comprises receiving the DC power from a least one of a set of batteries or a rectifier connected to the set of batteries.
4. The method of claim 3 , wherein changing the DC power to each unique power bus comprises allocating unique DC power from the set of batteries to each unique power bus.
5. The method of claim 4 , further comprising receiving instructions from an evolved node B (eNodeB) to change the DC power sent to a particular power bus connected to a particular remote radio head, wherein the instructions are created based on operational measurement of the cell site collected by the eNodeB.
6. The method of claim 5 , wherein the operational measurements include remote radio connections and access attempts of mobile device.
7. 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.
8. The system of claim 7 , wherein the set of power buses are integrated into the power distribution unit.
9. The system of claim 7 , further comprising the power distribution unit is connected to an evolved node B (eNodeB) to receive operational instructions to change the portion of the DC power sent to each power bus.
10. The system of claim 9 , wherein for the cell site, the DC power is uniquely allocated to each remote radio head through each power bus based on an operational performance of each cell site sector in the cell site.
11. The system of claim 10 , wherein the operational performance of each cell site sector includes remote radio connections and access attempts of mobile devices.
12. 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.
13. The system of claim 12 , wherein the group of power buses is integrated into the power distribution unit.
14. The system of claim 13 , wherein the power bus receives the DC power from a least one of a set of batteries or a rectifier connected to the set of batteries.
15. The system of claim 14 , wherein the power bus receives the change in the DC power comprises the power bus receives an allocation of the DC power from the set of batteries.
16. The system of claim 15 , further comprising a particular power bus connected to a particular remote radio head receives instructions from an evolved node B (eNodeB) to change the DC power, wherein the instructions are created based on operational measurement of the cell site collected by the eNodeB.
17. The system of claim 16 , wherein the operational measurements include remote radio connections and access attempts of mobile device.
