Multi-cell Configuration via Service Information Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-cell configuration methods in 3GPP New Radio communication systems lead to increased cell resource overhead and resource waste due to inefficient resumption or activation of multi-cell operations, particularly when switching from RRC inactive to RRC connected states.
Innovation Solution
A method where a terminal and base station exchange service configuration information, including radio bearer and cell measurement report thresholds, to determine and activate multi-cell operations only when necessary, reducing unnecessary resource allocation and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multi-cell operations are configured for UE in RRC inactive state, then data transmission capability is improved, but cell resource overhead increases and resource waste occurs
Solution Approach 1:
The network pre-configures measurement parameters and candidate cell information for the UE in RRC inactive state, enabling the UE to perform measurements and report results without establishing full RRC connection. This preliminary action allows the network to quickly determine whether multi-cell configuration is needed, avoiding unnecessary resource allocation while maintaining the capability for rapid data transmission when required.
2Speed
If multi-cell configuration information is transmitted to UE, then data transmission speed is improved, but transmission overhead increases
Solution Approach 1:
Instead of transmitting complete multi-cell configuration information to the UE in RRC inactive state, the patent transmits only partial configuration information including measurement parameters and candidate cell lists. The full configuration is only established when the UE reports measurement results indicating suitable candidate cells, thus achieving fast data transmission capability while minimizing transmission overhead.
3Productivity
If UE switches to RRC connected state for data transmission, then data transmission capability is improved, but switching time increases
Solution Approach 1:
The patent enables UE in RRC inactive state to perform cell measurements and report results to the network without switching to RRC connected state. The network uses these measurement reports to determine whether multi-cell configuration should be activated, making the state switching decision based on pre-collected measurement data rather than after switching, thus reducing switching time while maintaining data transmission capability.
4Speed
If complete configuration information is reserved for UE, then configuration resumption speed is improved, but memory resources are wasted
Solution Approach 1:
Instead of reserving complete multi-cell configuration information in the UE, the patent reserves only essential configuration elements such as measurement parameters and candidate cell identifiers. The full configuration information is retrieved or established on-demand based on measurement reports, optimizing the balance between configuration resumption speed and memory resource consumption.
