Wireless Measurement Report Type Selection for Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, determining the appropriate report type for measurement results based on downlink reception time or uplink transmission time is challenging, leading to issues with power consumption, accuracy, and signaling overhead, especially when cells enter or leave power-saving states.
Innovation Solution
A method where a first node receives signaling configurations indicating both a first and a second report type, using a parameter set to determine whether to report measurement results according to either type, thereby optimizing report types based on downlink or uplink times and conserving power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the network modifies the report type of each node in a dedicated way when changing downlink reception time or uplink transmission time, then the measurement accuracy is improved, but the signaling overhead increases
Solution Approach 1:
The UE automatically determines the appropriate report type (first or second) based on whether the first parameter set is indicated, without requiring dedicated network signaling for each modification. This self-service mechanism resolves the contradiction by eliminating the need for continuous dedicated signaling while maintaining accurate measurement reporting adapted to current timing conditions
2Loss of information
If the UE reports measurement results using a fixed report type, then the signaling overhead is reduced, but the power consumption increases due to unnecessary measurements during power-saving states
Solution Approach 1:
The report type is made dynamic and adaptable based on the parameter set indication status. When the first parameter set is indicated, the UE uses the first report type; when not indicated, it uses the second report type. This dynamic adaptation allows the system to reduce power consumption by selecting appropriate measurement and reporting behaviors matched to the current operational state, avoiding unnecessary measurements during power-saving conditions
3Loss of information
If the UE determines the report type automatically based on parameter set indication, then the signaling overhead is minimized, but the complexity of the UE increases
Solution Approach 1:
The UE monitors changes in the indication status of the first parameter set and automatically adjusts the report type accordingly. This parameter-based control mechanism resolves the contradiction by implementing a simple binary decision logic (parameter set indicated or not) that minimizes signaling overhead while avoiding complex algorithms or multiple configuration options, thus keeping UE complexity low
4Use of energy by moving object
If the network indicates different downlink reception time and uplink transmission time for power-saving states, then the power conservation is improved, but the measurement accuracy deteriorates due to timing misalignment
Solution Approach 1:
The system prepares two distinct report types in advance - a first report type for when the parameter set is indicated and a second report type for when it is not. This preliminary preparation allows the UE to immediately switch to the appropriate report type based on timing conditions without requiring real-time adjustments, thus maintaining measurement accuracy even when operating under different downlink and uplink timing configurations for power-saving states
