Terminal Beam Measurement for Adaptive Reception Reliability
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, receives a response, and determines an optimal reception beam using a measurement reference signal, thereby improving data transmission reliability and performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network device initiates measurement reporting procedures (periodic, semi-persistent, or aperiodic), then beam measurement can be performed, but the terminal device cannot actively respond to beam direction changes, causing reduced reliability and transmission performance loss
Solution Approach 1:
The patent inverts the traditional measurement initiation pattern by enabling the terminal device to actively request and trigger beam measurement procedures instead of passively waiting for network device initiation. The terminal sends first request information to the network device, receives first response information, and then receives measurement reference signals to actively determine optimal reception beams, thus resolving the contradiction between reliability and operational passivity
Solution Approach 2:
The terminal device performs self-service by autonomously initiating beam measurement procedures based on its own needs. The terminal sends requests for measurement reporting procedures (aperiodic, periodic, or semi-persistent) and independently determines optimal reception beams using received measurement reference signals, without requiring continuous network device control, thereby improving both reliability and operational independence
2Productivity
If the terminal device uses a fixed reception beam configuration, then the communication setup is simple, but the terminal cannot adapt to beam direction changes, causing transmission performance loss
Solution Approach 1:
The patent introduces dynamic beam measurement capabilities that allow the terminal device to adapt its reception beam configuration based on real-time needs. The terminal can request and perform aperiodic, periodic, or semi-persistent measurement procedures, dynamically determining optimal reception beams rather than using fixed configurations, thus improving transmission performance while managing complexity through structured procedures
3Loss of time
If the network device sends measurement reference signals immediately after receiving terminal requests, then the beam measurement response time is reduced, but the network device processing load increases
Solution Approach 1:
The network device performs preliminary actions by pre-configuring and preparing measurement reference signals and related parameters before receiving terminal device requests. This allows the network to quickly respond to measurement requests without immediate heavy processing, reducing response time while managing processing load through advance preparation of measurement resources

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. 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.
