Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Maintaining a stable radio connection is challenging due to power imbalances and misalignments in transmission and reception beams, leading to compromised uplink throughput and increased power consumption in wireless communication systems.
Innovation Solution
The apparatus autonomously provides and adjusts single-polarized radio beams in different directions based on feedback, allowing for reconfiguration of transmission to maintain and strengthen the radio connection by aligning transmission and reception powers.

Engineering Contradiction Analysis
1Productivity
If traditional radio beam transmission is used, then the radio connection can be maintained, but power imbalance and misalignment occur leading to compromised uplink throughput
Solution Approach 1:
The patent segments the radio beam transmission into separate polarization components (first polarization and second polarization) transmitted through different antenna ports. This segmentation allows independent optimization of each polarization path, enabling the system to address power imbalance and misalignment issues by adjusting individual polarization beams rather than treating the transmission as a single unified beam, thereby improving both uplink throughput and connection stability.
Solution Approach 2:
The patent applies local quality by providing different polarization characteristics to different spatial directions. The first polarization is transmitted in a first direction while the second polarization is transmitted in a second direction, allowing each direction to be optimized for its specific requirements. This enables the system to compensate for misalignment and power imbalance by locally adjusting polarization properties in different spatial regions.
2Reliability
If radio beam transmission is used to maintain connection, then connectivity is preserved, but power consumption increases
Solution Approach 1:
The patent implements feedback mechanisms where the terminal device provides feedback information about the received polarized radio beams to the network side. This feedback enables the system to monitor power consumption and connection quality in real-time, allowing dynamic adjustment of transmission parameters. By using feedback, the system can maintain reliable radio connections while optimizing power consumption by adjusting polarization transmission based on actual channel conditions and device requirements.
3Reliability
If single-polarized radio beams are provided in different directions, then power balance and alignment are improved, but system complexity increases
Solution Approach 1:
The patent applies universality by using the same antenna ports for both transmitting and receiving radio beams, making the antenna system multi-functional. The antenna ports serve dual purposes: transmitting polarized radio beams and receiving feedback signals. This multi-functionality reduces the need for separate dedicated transmission and reception antenna systems, thereby managing device complexity while still providing improved power balance and alignment through polarization diversity.
