Relay Link RRM Measurement Switching for Lower Terminal Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems, terminals in a non-connected state face challenges in reducing power consumption during radio resource management (RRM) measurements, particularly in sidelink scenarios involving relay terminals.
Innovation Solution
A first terminal adjusts RRM measurements of adjacent links based on criteria met by the serving link, with indication information from a serving device, such as a relay terminal, to enable power-saving measures like disabling or relaxing measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal performs RRM measurements on all neighboring cells to ensure mobility support, then the mobility reliability is improved, but the power consumption increases
Solution Approach 1:
The patent changes the measurement parameter configuration dynamically based on terminal state. When in connected state, the terminal performs measurements on all neighboring cells. When in non-connected state, the terminal performs measurements only on a subset of neighboring cells or with relaxed measurement requirements, thus reducing power consumption while maintaining adequate mobility support
Solution Approach 2:
The patent implements dynamic measurement configuration where the measurement behavior adapts to the terminal's connection state. The network can configure different measurement parameters for connected and non-connected states, allowing the system to optimize between mobility reliability and power consumption based on current operational requirements
2Adaptability or versatility
If the terminal performs RRM measurements in non-connected state to support cell reselection, then the cell reselection capability is improved, but the power consumption increases
Solution Approach 1:
The patent applies parameter changes by configuring different measurement parameters for non-connected state. The network can indicate to the terminal whether to perform RRM measurements on serving cell and neighboring cells when in non-connected state, allowing the terminal to adjust its measurement activity and power consumption accordingly
3Adaptability or versatility
If the terminal performs RRM measurements on serving relay terminal and adjacent relay terminals, then the relay selection capability is improved, but the power consumption increases
Solution Approach 1:
The patent extends the parameter changes principle to relay terminal measurements. The network can configure different measurement parameters for relay terminals based on the terminal's connection state, allowing relaxed measurement requirements in non-connected state to reduce power consumption while maintaining relay selection capability
