1Productivity
If advanced technologies such as THz communication, large-scale MIMO, integrated sensing and communication, and non-terrestrial networks are implemented, then data rate and connectivity reliability are improved, but device complexity and system configuration difficulty increase
Solution Approach 1:
The patent segments the positioning functionality into separate network entities (LMF, positioning management function) and dedicated signal types (positioning reference signals). This allows the complex integrated sensing and communication system to be divided into manageable components, where positioning, communication, and sensing can operate semi-independently, reducing overall system complexity while maintaining high data rates through advanced technologies like THz and large-scale MIMO.
2Measurement precision
If resource allocation for positioning is performed separately from communication resources, then positioning precision is improved, but resource utilization efficiency deteriorates
Solution Approach 1:
The patent merges positioning resources with communication resources by allowing positioning reference signals to be transmitted on physical uplink shared channels (PUSCH) and physical uplink control channels (PUCCH) that are already allocated for communication. This resource sharing approach maintains positioning precision through dedicated signal structures while improving resource utilization efficiency by eliminating separate resource allocations.
Solution Approach 2:
The patent implements multi-functionality by designing positioning reference signals that can be transmitted using existing communication channel structures (PUSCH, PUCCH). These channels serve dual purposes: carrying communication data and transmitting positioning reference signals, thereby achieving both precise positioning and efficient resource utilization through a universal resource allocation framework.
3Productivity
If positioning reference signals are transmitted using existing communication channels, then resource utilization is improved, but positioning signal quality may deteriorate
Solution Approach 1:
The patent applies local quality by configuring positioning reference signals with specific parameters (sequence patterns, resource element mappings, power levels) that are optimized for positioning functionality within the shared communication channels. This allows the positioning signals to maintain high quality and measurement precision while utilizing the same physical channels as communication signals, resolving the conflict between resource utilization and signal quality.
