Abstract
Aspects of the subject disclosure may include, for example, performing, by an adjusting mechanism associated with a communications system, polarization adjusting for an uplink of the communications system, and performing, by the adjusting mechanism, polarization adjusting for a downlink of the communications system, wherein a first polarization of the uplink and a second polarization of the downlink are different. Other embodiments are disclosed.
Claims20
A device, comprising:
- a processing system associated with a time-division duplexing (TDD) communications system and including a processor;
- and
- a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, the operations comprising:
- performing polarization adjusting for an uplink of the TDD communications system to mitigate passive intermodulation interference (PIM) in an intermediate-field region of an antenna that partially overlaps a near-field region of the antenna and a far-field region of the antenna responsive to receiving PIM information, wherein the polarization adjusting causes an elimination in a use of a guard band;
- and
- performing polarization adjusting for a downlink of the TDD communications system in the intermediate-field region, wherein a first polarization of the uplink and a second polarization of the downlink are different, wherein the polarization adjusting for the uplink, the downlink, or both are performed by physically rotating, or altering a physical property of, one or more radiating elements of the antenna without adjusting or moving a housing of the antenna, and wherein the one or more radiating elements convert radio frequency electrical current into a radiating electromagnetic wave.
A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processing system associated with a frequency-division duplexing (FDD) communications system and including a processor, facilitate performance of operations, the operations comprising:
- performing polarization adjusting for an uplink of the FDD communications system to mitigate passive intermodulation interference (PIM) in an intermediate-field region of an antenna that partially overlaps a near-field region of the antenna and a far-field region of the antenna responsive to receiving PIM information, wherein the polarization adjusting causes an elimination in a use of a guard band;
- and
- performing polarization adjusting for a downlink of the FDD communications system in the intermediate-field region, wherein a first polarization of the uplink and a second polarization of the downlink are different, wherein the polarization adjusting for the uplink, the downlink, or both are performed by physically rotating, or altering a physical property of, one or more radiating elements of the antenna without adjusting or moving a housing of the antenna, and wherein the one or more radiating elements convert radio frequency electrical current into a radiating electromagnetic wave.
