Dynamic Polarization Configuration for Multi-Polarized Antenna Link Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication systems using multi-polarized antennas have static polarization configurations, which fail to adapt to runtime changes, leading to reduced link reliability and data rate due to lack of de-correlation between spatial streams, and rely on unnecessary data rate reduction or modulation and coding scheme changes.
Innovation Solution
Implementing a framework within network devices to dynamically modify antenna properties, such as polarization configurations, based on feedback information to maintain optimal de-correlation and link reliability, rather than reducing data rates, by selecting alternative polarization configurations or beam patterns to ensure acceptable quality of service.

Engineering Contradiction Analysis
1Reliability
If conventional static polarization configuration is used, then device complexity is reduced, but link reliability deteriorates due to lack of de-correlation between spatial streams
Solution Approach 1:
The patent applies dynamics by transitioning from static polarization configuration to dynamic run-time modification. The system now adjusts antenna polarization configurations based on feedback information about link quality, allowing the antenna properties to change adaptively over time to maintain optimal de-correlation between spatial streams, thereby improving link reliability without requiring complex manual reconfiguration.
Solution Approach 2:
The patent changes the polarization parameter of antennas at run-time based on feedback information. By modifying antenna properties such as polarization configuration dynamically, the system optimizes de-correlation between spatial streams to enhance link reliability while avoiding unnecessary data rate reduction or MCS changes.
2Reliability
If data rate is reduced to maintain QoS, then quality of service is maintained, but productivity deteriorates
Solution Approach 1:
Instead of reducing data rate to maintain QoS, the patent changes antenna polarization parameters dynamically. This alternative approach maintains the current data rate and QoS by improving link reliability through enhanced de-correlation, thereby avoiding productivity loss while still ensuring acceptable service quality.
3Reliability
If conventional rate control schemes are used, then quality of service is maintained through MCS switching, but adaptability deteriorates because failures due to lack of de-correlation are not addressed
Solution Approach 1:
The patent implements feedback mechanisms that monitor link quality and provide information about transmission failures. This feedback is used to dynamically adjust antenna polarization configurations, enabling the system to adapt specifically to de-correlation issues rather than relying solely on generic MCS switching, thereby improving both reliability and adaptability.
Solution Approach 2:
The system adapts by changing antenna polarization parameters in response to feedback about link failures. This provides targeted adaptability to address de-correlation issues specifically, rather than relying only on MCS switching, enhancing the system's versatility in handling different failure modes.

AI summary
According to one embodiment of the disclosure, a non-transitory computer-readable medium comprising instructions which, when executed by one or more hardware processors, causes performance of operations. One of these operations comprises transmitting, from a first device to a second device, a first plurality of frames using a first polarization configuration for a first antenna corresponding to the first device. Based on feedback information associated with the first plurality of frames, a second polarization configuration, which is different than the first polarization configuration, is selected for transmitting a second plurality of frames. Thereafter, the second plurality of frames is transmitted from the first device to the second device using the second polarization configuration for the first antenna.
