Assigning carriers to radio ports of a split radio head
Assigning carriers to radio ports communicably coupled to a corresponding plurality of antennae of a radio head, wherein the radio head is split into at least first and second split portions, determining a difference between a first power level available to the first carrier via the first set of radio ports and a second power level available to the second carrier via the second set of radio ports, and changing a split of the radio head such that the difference between the first and second power levels is minimized.
1. A method for assigning carriers to radio ports in a wireless network, the method comprising:
assigning a priority to one or more carriers deployed by an access node;
dividing a radio head coupled to the access node into a plurality of split portions; and
assigning a number of radio ports to each of the split portions based on the priority of each of the one or more carriers and based on respective composite power levels available to each of the one or more carriers,
wherein the composite power level available to a respective carrier corresponds to the number of radio ports included in the split portion to which the respective carrier is assigned, divided by a total number of carriers assigned to the split portion to which the respective carrier is assigned.
2. The method of claim 1 , further comprising assigning the priority based on one or more of frequencies used by each carrier, a throughput of each carrier, and a propagation characteristic of each carrier.
3. The method of claim 2 , wherein the priority is based on requirements of wireless devices attached to the access node.
4. The method of claim 3 , wherein the requirements of the wireless devices are based on a location of the wireless device within a coverage area of the access node.
5. The method of claim 3 , further comprising adjusting a weighted power requirement of each carrier based on the requirements of the wireless devices.
6. The method of claim 2 , further comprising assigning a relatively higher priority to a carrier using a relatively lower frequency.
7. The method of claim 6 , further comprising assigning a relatively lower priority to a carrier using a relatively higher frequency.
8. The method of claim 2 , further comprising assigning a relatively higher priority to a carrier serving a relay node.
9. The method of claim 1 , further comprising assigning a greater number of radio ports to a carrier having relatively higher priority.
10. The method of claim 1 , further comprising determining a difference between a first composite power level available to a first carrier via a first split portion of the plurality of split portions and a second composite power level available to a second carrier via a second split portion of the plurality of split portions; and assigning the number of radio ports to each carrier such that the difference between the first and second composite power levels is minimized.
11. A system for assigning carriers to radio ports in a wireless network, the system comprising:
an access node configured to deploy a plurality of carriers;
a radio head coupled to the access node, the radio head comprising a plurality of radio ports coupled to a corresponding plurality of antennae of the access node, the radio head being divided into a plurality of split portions; and
a processor coupled to the access node, the processor configured to perform operations comprising:
assigning a priority to one or more carriers deployed by the access node; and
assigning a number of radio ports to each of the split portions based on the priority of each of the one or more carriers and based on respective composite power levels available to each of the one or more carriers,
wherein the composite power level available to a respective carrier corresponds to the number of radio ports included in the split portion to which the respective carrier is assigned, divided by a total number of carriers assigned to the split portion to which the respective carrier is assigned.
12. The system of claim 11 , wherein the operations further comprise assigning the priority based on one or more of frequencies used by each carrier, a throughput of each carrier, and a propagation characteristic of each carrier.
13. The system of claim 12 , wherein the priority is based on requirements of wireless devices attached to the access node.
14. The system of claim 13 , wherein the requirements of the wireless devices are based on a location of the wireless device within a coverage area of the access node.
15. The system of claim 13 , wherein the operations further comprise adjusting a weighted power requirement of each carrier based on the requirements of the wireless devices.
16. The system of claim 12 , wherein the operations further comprise assigning a relatively higher priority to a carrier using a relatively lower frequency.
17. The system of claim 16 , wherein the operations further comprise assigning a relatively lower priority to a carrier using a relatively higher frequency.
18. The system of claim 12 , wherein the operations further comprise assigning a relatively higher priority to a carrier serving a relay node.
19. The system of claim 11 , wherein the operations further comprise assigning a greater number of radio ports to a carrier having relatively higher priority.
20. The system of claim 11 , wherein the operations further comprise determining a difference between a first power composite level available to a first carrier via a first split portion of the plurality of split portions and a second power composite level available to a second carrier via a second split portion of the plurality of split portions; and assigning the number of radio ports to each carrier such that the difference between the first and second composite power levels is minimized.
