Abstract

Aspects of the subject disclosure may include, for example, receiving, via an antenna, a communication signal generated by a communication device, and detecting interference in the communication signal, wherein the interference is generated by one or more interference sources, wherein the interference is detected by monitoring a near field region of the antenna, an intermediate field region of the antenna, a far field region of the antenna, or any combinations thereof, wherein the monitoring excludes monitoring only the far field region of the antenna. Other embodiments are disclosed.

First claim

What is claimed is:

1. A method, comprising:
detecting interference in a communication signal received by an antenna system that includes a first set of radiating elements associated with a first band and a second set of radiating elements associated with a second band, wherein the interference is generated by one or more interference sources, and wherein the interference is detected by monitoring a near field region of the antenna system, an intermediate field region of the antenna system, a far field region of the antenna system, or any combinations thereof; and
based on the detecting, performing polarization adjusting for the first set of radiating elements, by a first adjustment amount and for the second set of radiating elements by a second adjustment amount different from the first adjustment amount.

2. The method of claim 1 , wherein the intermediate field region comprises a region that spans a portion of the near field region of the antenna system and a portion of the far field region of the antenna system.

3. The method of claim 1 , further comprising:
identifying an antenna resource for mitigating the interference; and
performing, by the antenna resource, conditioning on the communication signal to reduce the interference.

4. The method of claim 1 , wherein the first and second bands mix and interfere together.

5. The method of claim 4 , wherein the interference detected includes mixing and interference of the first and second bands, and wherein the interference detected comprises passive intermodulation (PIM) interference.

6. The method of claim 1 , wherein the interference comprises inter-cell interference.

7. The method of claim 1 , wherein the interference is generated from dynamic spectrum sharing between transmitters.

8. The method of claim 1 , wherein the interference comprises leakage interference generated by another base station.

9. The method of claim 1 , wherein a polarization of the interference enables detection of the interference.

10. The method of claim 9 , wherein the polarization of the interference is detectable separately from other signals received by the antenna system.

11. The method of claim 1 , wherein the antenna system is integrated with a remote radio head.

12. The method of claim 1 , wherein the antenna system operates in a communication system utilizing time division multiple access.

13. The method of claim 1 , wherein the antenna system operates in a communication system utilizing frequency division multiple access.

14. The method of claim 1 , wherein a signaling protocol used by one or more transmitters unassociated with the antenna system comprises an orthogonal frequency-division multiple access protocol.

15. The method of claim 14 , wherein the interference is further detected by detecting the signaling protocol used by the one or more transmitters.

16. A device, comprising:
a circuit coupled to an antenna system that includes a first set of radiating elements associated with a first band and a second set of radiating elements associated with a second band, the circuit facilitating operations including:
detecting interference in a signal received via the antenna system, wherein the interference is generated by one or more sources, and wherein the interference is detected by monitoring an intermediate field region of the antenna system that spans a portion of a near field region of the antenna system and a portion of a far field region of the antenna system; and
based on the detecting, causing polarization adjusting to be performed for the first set of radiating elements, by a first adjustment amount and for the second set of radiating elements by a second adjustment amount different from the first adjustment amount.

17. The device of claim 16 , wherein the operations further include identifying a resource for mitigating the interference.

18. The device of claim 16 , wherein the circuit is configured to detect a polarization of the interference.

19. A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processing system including a processor, facilitate performance of operations, the operations comprising:
detecting interference in a communication signal received by an antenna system that includes a first set of radiating elements associated with a first band and a second set of radiating elements associated with a second band, wherein the interference is detected by monitoring an intermediate field region of the antenna system that spans a portion of a near field region of the antenna system and a portion of a far field region of the antenna system; and
based on the detecting, performing polarization adjusting for the first set of radiating elements, by a first adjustment amount and for the second set of radiating elements by a second adjustment amount different from the first adjustment amount.

20. The non-transitory machine-readable medium of claim 19 , wherein the operations further comprise controlling, by a remote radio unit, the antenna system to perform one or more actions for mitigating or cancelling the interference.
