Wireless Network Measurement Delays for Idle-State Battery Savings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies face challenges in optimizing network performance due to inefficiencies in early measurements, battery consumption, and mobility failures, particularly in scenarios involving dormant bandwidth parts and dual connectivity, without adequate reporting mechanisms for UE assistant information and quality of service adjustments.
Innovation Solution
Introduce delay times for early measurements based on UE states, report PSCell state during SCG failures, enhance mobility reporting with DAPS, CPAC, and CHO failure information, and adjust UE assistant information usage, along with dynamic QoS parameter mapping for XR services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If early measurements are performed immediately upon entering idle or inactive state, then measurement speed is improved, but battery consumption increases
Solution Approach 1:
The system performs preliminary actions by pre-configuring measurement parameters and delay values before the UE enters idle or inactive state. The network node provides delay values in advance, and the UE prepares measurement configurations beforehand, so that when the state transition occurs, measurements can start quickly without immediate full activation, thus balancing speed and energy consumption.
2Measurement precision
If delay values are configured for all UE states, then measurement accuracy is improved, but device complexity increases
Solution Approach 1:
Different delay values are configured for different UE states (idle state versus inactive state). The network node provides a first delay value specifically for idle state and a second delay value specifically for inactive state. This localized configuration approach ensures that each state receives the appropriate delay setting for its specific characteristics, improving measurement accuracy while avoiding the need for a single complex universal configuration.
3Reliability
If comprehensive reporting mechanisms are implemented for SCG failures and mobility events, then network reliability is improved, but signaling overhead increases
Solution Approach 1:
The patent extracts and reports only the most critical information elements related to SCG failures and mobility events. Instead of comprehensive reporting of all possible parameters, the system focuses on extracting key failure causes, specific event triggers, and essential measurement results. This selective extraction approach maintains network reliability by reporting necessary failure information while reducing signaling overhead by omitting redundant data.

AI summary
Techniques are described to improve performance of a wireless network and/or devices within the wireless network. For example, a wireless communication method comprises receiving, by a communication node at a first time, one or more delay values, where each delay value is indicative of amount of time by which a measurement is to be delayed, and performing the measurement at or after a third time, where the third time is based on a delay value from the one or more delay values and a second time when the communication node enters an idle state or an inactive state, where the first time precedes the second time in time, and where the second time precedes the third time in time.
