Wireless Measurement Object Configuration for Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, improper configuration of measurement objects for synchronization signals and channel state information-reference signals leads to inaccurate measurements and power wastage, and reconfiguring these for each user is inefficient, especially when transitioning between power saving states, resulting in high signaling overhead.
Innovation Solution
A method where a first node receives signaling to configure both a first and a second measurement object, with the option to perform measurements based on either, depending on the indication of a parameter set, which determines the downlink reception or uplink transmission time, allowing for adaptive measurement performance and reduced signaling overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measurement objects are reconfigured for each user separately, then measurement accuracy is improved, but signaling overhead increases
Solution Approach 1:
The patent divides measurement objects into two types: first measurement objects for power saving states and second measurement objects for normal operation. This segmentation allows the system to use different measurement configurations based on the user equipment's power state, reducing signaling overhead while maintaining measurement accuracy when needed.
Solution Approach 2:
The patent implements dynamic switching between first and second measurement objects based on power saving state indications. The network device can dynamically indicate whether to use the first or second measurement object, allowing adaptive measurement configuration that responds to changing power requirements without requiring full reconfiguration signaling.
2Measurement precision
If measurement objects are reconfigured for each user separately, then measurement accuracy is improved, but power consumption increases
Solution Approach 1:
The patent segments measurement objects into power-saving oriented first measurement objects and accuracy-oriented second measurement objects. User equipment in power saving states uses the first measurement objects with reduced measurement requirements, while maintaining the ability to switch to second measurement objects when accuracy is needed, thus balancing power consumption and measurement accuracy.
Solution Approach 2:
The patent changes measurement parameters based on power saving state indications. When in power saving state, the system uses first measurement objects with relaxed measurement parameters (e.g., less frequent measurements, reduced precision requirements). When exiting power saving state, the system switches to second measurement objects with stricter parameters, adapting measurement behavior to power availability.
3Use of energy by moving object
If downlink reception time or uplink transmission time is adjusted for power saving, then power consumption is reduced, but measurement accuracy deteriorates
Solution Approach 1:
The patent implements dynamic adjustment of measurement object usage based on power saving state transitions. When power saving is activated, the system dynamically switches to first measurement objects that are configured to work with adjusted downlink reception or uplink transmission times. When power saving is deactivated, the system dynamically switches to second measurement objects for accurate measurements, allowing the system to adapt measurement behavior to timing adjustments without permanent accuracy loss.
