Reception Beam Adjustment via Motion Sensor Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In advanced wireless communication systems, especially those using millimeter wave (mmWave) technology like 5G NR, beam alignment between transmitter and receiver is challenging due to environmental factors, leading to misalignment and interference, which requires time-consuming beam forming protocol processes to re-establish alignment, disrupting communication.
Innovation Solution
The method involves user equipment (UE) and base stations using motion sensors to determine angular movement and adjust beam directions dynamically based on received beam direction change information, allowing for active adjustment of reception beams to maintain alignment without interrupting communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beam forming protocol process is used to re-establish beam alignment, then beam alignment reliability is improved, but communication continuity deteriorates due to interruption
Solution Approach 1:
The system performs preliminary beam alignment establishment during initial connection, storing beam direction information for future use. When relative motion occurs, the pre-established beam parameters serve as a starting point for quick adjustment, avoiding complete re-alignment protocols and maintaining communication continuity while ensuring alignment reliability.
2Measurement precision
If traditional beam forming protocol is executed to realign beams, then beam alignment accuracy is improved, but time consumption increases
Solution Approach 1:
The system dynamically adjusts beam directions based on real-time relative motion detection between UE and base station. By continuously monitoring motion state and actively updating beam parameters, the system maintains accurate beam alignment without requiring time-consuming periodic re-alignment protocols, thus improving alignment accuracy while reducing time consumption.
3Device complexity
If beam direction is fixed, then device complexity is reduced, but adaptability to environmental changes deteriorates
Solution Approach 1:
The system implements feedback mechanisms where the base station detects relative motion between UE and base station, determines beam direction changes, and sends control signals to adjust UE beam directions. This closed-loop feedback enables the system to adapt to environmental changes and maintain optimal beam alignment without requiring complex manual configuration, achieving both simplicity and adaptability.

AI summary
A user equipment (UE) is configured to perform a method for adjusting a reception beam. The UE performs receiving first communication signals from a base station using the reception beam having the first reception beam direction, wherein the first communication signals comprise beam direction change information; adjusting the reception beam from the first reception beam direction to a second reception beam direction in accordance with the beam direction change information; and receiving second communication signals from the base station based on the reception beam having the second reception beam direction. Through the method, the UE may actively adjust the reception beam direction based on relative movement between base station beam and itself.
