L-Shaped Antenna Module Dynamic Element Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems with L-shaped antenna modules face sub-optimal performance due to static antenna configurations and power consumption issues, particularly in scenarios with blockages or varying signal angles, as they rely on static combinations of horizontal and vertical polarizations across the 'L' shape.
Innovation Solution
Implement a dynamic selection mechanism for antenna elements within the L-shaped antenna module, allowing users to switch between co-polarization and cross-polarization configurations based on measurement feedback from reference signals, enabling optimal performance and power management by adjusting antenna configurations dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If static antenna configurations are used in L-shaped antenna modules, then device complexity is reduced and ease of operation is improved, but communication performance deteriorates in scenarios with blockages or varying signal angles
Solution Approach 1:
The patent implements dynamic antenna configuration selection by enabling the wireless device to switch between different antenna element configurations (e.g., first configuration using horizontal polarizations, second configuration using vertical polarizations) based on measured signal conditions. This dynamic adaptation resolves the contradiction by allowing the system to maintain simple operation while achieving reliable communication performance through real-time configuration changes based on blockage detection and signal angle variations.
Solution Approach 2:
The patent changes the operational parameters of the antenna module by switching between different polarization configurations (horizontal vs. vertical) and different antenna element combinations. These parameter changes enable the system to adapt to varying signal conditions and blockages, improving communication reliability without requiring complex manual intervention, thus resolving the contradiction between performance and complexity.
2Reliability
If dynamic selection of antenna elements is implemented, then communication performance and power efficiency are enhanced, but device complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where the wireless device measures reference signals from the network device, evaluates different antenna element configurations based on these measurements, and selects the optimal configuration accordingly. This feedback-driven approach enhances communication performance and power efficiency by making informed selection decisions, while the automated nature of the process prevents excessive complexity increase through systematic rather than ad-hoc complexity management.
3Reliability
If all antenna elements are continuously activated, then communication coverage and signal quality are improved, but power consumption increases
Solution Approach 1:
The patent dynamically activates or deactivates specific antenna elements based on the selected configuration. For example, when the first configuration is selected, only antenna elements associated with horizontal polarizations are activated, while elements for vertical polarizations are deactivated, and vice versa. This dynamic activation strategy maintains signal quality by ensuring the active elements are optimally suited for current propagation conditions while significantly reducing power consumption by keeping unnecessary elements inactive.
Solution Approach 2:
The patent applies partial action by activating only the necessary subset of antenna elements required for the current communication scenario rather than all elements continuously. By selecting and activating only the relevant antenna elements (either horizontal or vertical polarization elements based on conditions), the system achieves adequate signal quality with reduced power consumption, avoiding the excessive action of keeping all elements active at all times.

AI summary
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may include an L shaped antenna module, which may include a first array of antenna elements in one dimension and a second array of antenna elements in a second dimension. In an L shaped antenna module, antenna element configurations may be used that combine antenna elements across the two sides of the “L”. In some aspects, a UE may dynamically select a configuration of antenna elements of an L shaped antenna module to enhance performance and power consumption. In some aspects, the UE may select whether to use a cross-polarization configuration or a co-polar configuration for the L shaped antenna module.
