Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for further improvements in New Radio (NR) and LTE technology to enhance mobile broadband access, particularly in terms of channel measurement techniques.
Innovation Solution
The method involves determining whether to activate resources on candidate component carriers (CCs) for communication of reference signals based on the signal quality of a serving CC, and then communicating these reference signals and receiving data transmissions on the activated CCs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If channel measurement resources are continuously activated on candidate component carriers, then channel measurement capability is maintained, but system overhead increases
Solution Approach 1:
The patent applies dynamics by transitioning from continuous static activation of channel measurement resources to dynamic conditional activation. Resources are activated only when needed based on serving cell signal quality conditions, allowing the system to adapt its configuration dynamically rather than maintaining a fixed continuous state.
Solution Approach 2:
The patent implements periodic monitoring of signal quality conditions to determine resource activation status. By periodically assessing whether activation conditions are met rather than maintaining continuous activation, the system achieves periodic action that reduces overhead while maintaining measurement capability when required.
2Device complexity
If channel measurement resources are not activated, then system overhead is reduced, but channel measurement accuracy deteriorates
Solution Approach 1:
The patent employs feedback mechanisms where the UE reports signal quality measurements of the serving cell to the network. This feedback information is then used by the network to dynamically determine whether to activate channel measurement resources on candidate cells, creating a closed-loop control system that balances overhead reduction with measurement accuracy needs.
Solution Approach 2:
The patent applies preliminary action by pre-configuring candidate component carriers with available channel measurement resources before actual measurement needs arise. When activation conditions are met, the system can quickly activate these pre-prepared resources without delay, ensuring measurement accuracy is maintained when needed while avoiding continuous activation overhead.
3Productivity
If dynamic activation based on signal quality is implemented, then resource efficiency improves, but control complexity increases
Solution Approach 1:
The patent applies self-service by enabling the UE to autonomously measure and report signal quality of the serving cell without requiring continuous network control. The UE independently determines when activation conditions are met and communicates this information to the network, reducing the control burden on the network while maintaining efficient resource utilization.
Data Source
AI summary
Certain aspects of the present disclosure are generally directed to a method for wireless communication. The method generally includes determining whether to activate resources on one or more candidate component carriers (CCs) to be used for communication of one or more reference signals with a network based on a signal quality of a serving CC, communicating the one or more reference signals with the network if the resources on the one or more candidate CCs are activated based on the determination, and receiving a data transmission on one of the one or more candidate CCs after the communication of the one or more reference signals.
