Terminal Measurement Control with LP-WUS Offloading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems, particularly those using higher frequency bands like New Radio (NR), excessive continuous measurement operations by terminals lead to increased power consumption and potential degradation of user-perceived data rates.
Innovation Solution
A method and apparatus for controlling measurement operations based on measurement results and predictions, utilizing low-power wake-up receivers (LP-WUR) and main receivers (MR) to perform measurement offloading, with criteria defined by measurement thresholds and prediction, reducing unnecessary measurements and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the terminal continuously performs measurement operations for downlink signals, then the measurement accuracy and mobility management quality are improved, but the power consumption increases
Solution Approach 1:
The terminal performs measurement prediction operations in advance to forecast whether continuous measurement will be needed. By predicting future measurement requirements based on current downlink signal conditions, the terminal can avoid unnecessary continuous measurements and reduce power consumption while maintaining measurement accuracy when needed
Solution Approach 2:
The measurement operation mode is dynamically adjusted based on prediction results. When prediction indicates good downlink signal conditions, the terminal switches to discontinuous measurement mode to save power. When conditions deteriorate, the terminal transitions to continuous measurement mode to maintain accuracy, creating a flexible adaptive measurement system
2Reliability
If the terminal performs excessive continuous measurement operations, then the mobility management and radio connection quality are improved, but the user-perceived data rates deteriorate
Solution Approach 1:
The terminal uses measurement prediction to anticipate future measurement needs before they arise. By predicting whether continuous measurement will be necessary based on current signal conditions and historical patterns, the terminal can avoid unnecessary measurements that would consume processing resources and degrade user-perceived data rates
Solution Approach 2:
Instead of performing continuous measurements regardless of conditions, the terminal performs measurements selectively based on prediction results. When prediction indicates stable conditions, the terminal performs partial or reduced measurements, avoiding excessive operations that would harm user experience while maintaining sufficient measurement quality for radio connection management

AI summary
Disclosed are a measurement control method and apparatus in a communication system. A method of a terminal may comprise: receiving measurement offloading configuration information from a base station; performing a first measurement operation for downlink (DL) signals; determining whether the terminal is located within a potential low-power wake up signal (LP-WUS) reception coverage based on the measurement offloading configuration information and a first result of the first measurement operation; in response to determining that the terminal is located within the potential LP-WUS reception coverage, performing a second measurement operation for LP-WUS; and performing the first measurement operation or the second measurement operation based on a second result of the second measurement operation.
