Abstract
Aspects of the subject disclosure may include, for example, polarization adaptation in panel MIMO antennas to improve isolation between downlink beams so as to reduce or minimize beam interference, which improves antenna performance and/or reduces antenna size requirements. Other embodiments are disclosed.
Claims20
A method, comprising:
- forming multiple beams associated with subarrays of an antenna, the antenna being part of a communications system;
- and
- performing different polarization rotations of signals associated with beams of the multiple beams that at least partially overlap so as to reduce interference imposed by those signals on one another by electronically rotating signals associated with a row or column of the subarrays of the antenna differently from signals associated with one or more neighboring rows or columns of the subarrays of the antenna so as to increase beam isolation in a direction of elevation, azimuth or both.
A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processing system including a processor and associated with an antenna of a communications system, facilitate performance of operations, the operations comprising:
- forming multiple beams associated with subarrays of the antenna;
- and
- performing polarization rotations of signals associated with beams of the multiple beams that at least partially overlap so as to mitigate interference imposed by those signals on one another by electronically rotating signals associated with one row or column of the subarrays of the antenna differently from signals associated with one or more neighboring rows or columns of the subarrays of the antenna so as to increase beam isolation in a direction of elevation, azimuth or both.
A device, comprising:
- a processing system including a processor;
- and
- a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, the operations comprising:
- forming a beam using subarrays of one or more antennas;
- and
- performing one or more polarization rotations of one or more signals associated with the beam to reduce interference caused by an overlap of the beam with another beam associated with another device by electronically rotating signals associated with one row or column of the subarrays of the antennas differently from signals associated with one or more neighboring rows or columns of the subarrays of the antennas so as to increase beam isolation in a direction of elevation, azimuth or both.
