Terminal Antenna Modules for Fixed-Shield Beam Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies fail to accurately measure communication quality due to the shielding effect of a user's body, particularly in high frequency bands, which affects beam selection and communication quality.
Innovation Solution
A terminal apparatus with antenna modules and a control unit that changes the receivable direction of the antenna modules while fixing the shield state, allowing for accurate measurement of downlink communication quality by eliminating the shielding effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beam sweeping is performed to select optimum beams for communication, then communication quality can be improved, but measurement accuracy deteriorates due to shielding effect of user body
Solution Approach 1:
The patent applies preliminary action by having the user hold the terminal in a predetermined position before measurement begins. The control unit instructs the user to assume a specific posture (e.g., holding the terminal with both hands in front of the body) before beam sweeping starts, ensuring the shield state is fixed in advance. This preliminary positioning eliminates shielding effects during the measurement process, allowing accurate measurement of communication quality without distortion from user body interference.
2Productivity
If high frequency band is used to achieve large-capacity communication, then throughput is improved, but coverage deteriorates due to increased propagation attenuation
Solution Approach 1:
The patent applies parameter changes by measuring communication quality across multiple frequency bands (including both high and low frequency bands) and selecting the appropriate band based on measurement results. The control unit obtains measurement results for downlink communication in different frequency bands and uses these results to determine the optimal frequency band for communication. This allows the system to adaptively choose between high frequency bands for throughput and low frequency bands for coverage based on actual propagation conditions.
3Ease of operation
If measurement is performed without fixing shield state, then ease of operation is improved, but measurement precision deteriorates due to variable shielding effects
Solution Approach 1:
The patent applies self-service by having the user actively participate in establishing the measurement conditions. The control unit provides instructions to the user about the predetermined holding posture, and the user performs the action of holding the terminal in the specified position. This self-service approach ensures the shield state is consistently reproduced during measurement without requiring complex automated positioning systems, maintaining ease of operation while achieving measurement precision.

AI summary
A terminal apparatus including one or more antenna modules, and a control unit that controls a process for changing a receivable direction of the antenna module used for measurement while fixing a shield state of the antenna module as a state produced by a shield, and a process for measuring downlink communication quality according to the change of the receivable direction of the antenna module used for the measurement.
