Beam Measurement Timing for Fast Reception Beam Re-Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in maintaining data transmission reliability and performance due to changes in the direction of a terminal device's reception beam, leading to reduced reliability and performance loss.
Innovation Solution
A beam measurement method where a terminal device actively requests a measurement reporting procedure by sending first request information to a network device, receiving a response, and determining an optimal reception beam based on a measurement reference signal, thereby improving data transmission reliability and performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network device determines whether to initiate measurement reporting procedures, then the system maintains control over measurement timing, but the terminal device cannot quickly re-determine optimal reception beam when rotating or moving
Solution Approach 1:
The patent inverts the traditional control relationship by enabling the terminal device to actively initiate measurement reporting procedures through uplink indication information, rather than having the network device unilaterally control measurement initiation. This inversion allows the terminal device to quickly request beam measurements when it detects rotation or movement, improving responsiveness while maintaining network control through configuration management.
Solution Approach 2:
The terminal device performs self-service by autonomously determining when beam re-evaluation is needed based on its own rotation or movement state, and actively initiating measurement reporting procedures without waiting for network device triggers. This self-service mechanism enables rapid beam optimization responsive to terminal device state changes.
2Reliability
If periodic measurement reporting procedures are used, then beam measurements are performed regularly, but transmission performance is lost when terminal device changes direction between measurements
Solution Approach 1:
The patent introduces dynamic measurement reporting by allowing the terminal device to adaptively trigger measurements based on its real-time rotation or movement state. Instead of fixed periodic measurements, the system dynamically initiates measurements when needed, ensuring beam optimization occurs at critical moments while reducing unnecessary measurements during stable periods.
Solution Approach 2:
The terminal device provides feedback to the network device about its rotation or movement state through uplink indication information. This feedback mechanism enables the network device to understand when the terminal device needs beam re-evaluation, allowing timely measurement reporting that maintains transmission performance during directional changes.
3Ease of operation
If the terminal device actively requests measurement reporting, then beam optimization responsiveness improves, but signaling overhead between terminal device and network device increases
Solution Approach 1:
The patent makes the uplink indication information multi-functional by using it both for its original purpose (triggering scheduling or resource allocation) and additionally for initiating measurement reporting procedures. This universal usage reduces signaling overhead by consolidating multiple control functions into a single information element rather than requiring separate signaling for each function.

AI summary
A beam measurement method and apparatus are provided, to improve data transmission reliability and transmission performance when a terminal device communicates with a network device over a beam. The method includes: A terminal device sends first request information to a network device, receives first response information from the network device, and receives a measurement reference signal from the network device after a first time offset starting from a sending moment or a receiving moment of the first response information. The first request information is for requesting to initiate a measurement reporting procedure, and the first response information indicates that the network device agrees to initiation of a measurement reporting procedure.
