1Speed
If existing methods for activating or deactivating radio resource configurations are used, then the configuration can be changed, but it takes a long time affecting transmission efficiency
Solution Approach 1:
The patent pre-configures multiple CORESET and QCL parameter sets in advance (e.g., CORESET1-QCL1, CORESET2-QCL2 pairs) and stores them in the UE. When activation/deactivation is needed, the network simply indicates which pre-configured set to use, avoiding time-consuming real-time configuration establishment and enabling rapid switching.
Solution Approach 2:
The patent implements dynamic activation and deactivation of radio resource configurations through MAC CE signaling. The network can flexibly activate or deactivate specific CORESET-QCL configurations based on current transmission needs, allowing the system to adapt quickly to changing conditions without reconfiguring all parameters.
2Productivity
If radio resource configuration is activated or deactivated, then resource utilization can be optimized, but the process is time-consuming
Solution Approach 1:
Multiple radio resource configurations are prepared in advance at the UE side, including different CORESET and QCL parameter sets. When the network needs to switch configurations, it only needs to indicate which pre-configured set to activate, enabling rapid resource optimization without time-consuming configuration establishment.
Solution Approach 2:
The patent divides the radio resource configuration into separate, independently controllable components (CORESET configurations and QCL configurations). Each can be activated or deactivated independently through separate MAC CE signaling, allowing fine-grained resource optimization and reducing the time needed to adjust specific configurations.
3Productivity
If rapid activation or deactivation of radio resource configuration is implemented, then transmission efficiency improves, but timing consistency between network-side and user-side devices must be ensured
Solution Approach 1:
The patent incorporates feedback mechanisms where the UE confirms receipt and execution of activation/deactivation commands from the network. This ensures that both network-side and user-side devices have consistent understanding of the current configuration state, maintaining reliability while enabling rapid changes.
Solution Approach 2:
The network and UE both pre-configure the same set of radio resource configurations in advance with identical parameters. When activation/deactivation occurs, both sides already have the configuration data ready, ensuring timing consistency without requiring lengthy configuration transfer or verification processes.
