1Measurement precision
If sensing tasks are performed on a target UE in sidelink with assistance from another UE, then sensing capability is enhanced, but the method for achieving this sensing task with assistance is unclear
Solution Approach 1:
The patent introduces a network element as an intermediary to coordinate the sensing task between the target UE and the assisting UE. The network element receives sensing task information from the target UE, selects an appropriate assisting UE based on capability matching, and manages the sensing process, thereby making the complex sensing operation clear and manageable.
Solution Approach 2:
The assisting UE autonomously performs sensing measurements and reports results back to the target UE or network element without requiring continuous direct control from the target UE. This self-service mechanism simplifies the overall operation by allowing the assisting UE to independently execute the sensing task once selected.
2Productivity
If another UE is selected to perform sensing task, then sensing task execution is enabled, but connection establishment between assisting UE and network element is unclear
Solution Approach 1:
The network element performs preliminary actions by pre-establishing connection management procedures and selecting the assisting UE before the actual sensing task begins. The network element receives capability information from UEs in advance, pre-evaluates which UE can assist, and prepares the connection framework, thereby simplifying the execution phase.
Solution Approach 2:
The system implements feedback mechanisms where the assisting UE reports sensing results and capability information back to the network element and target UE. This feedback loop enables the network element to adjust connection management dynamically and ensures that the assisting UE remains appropriately connected throughout the sensing task execution.
