1Productivity
If traditional resource allocation methods are used in heterogeneous wireless networks, then system complexity is reduced, but resource allocation efficiency for sensing services deteriorates
Solution Approach 1:
The patent segments resource allocation by introducing separate QoS parameter sets for sensing services versus traditional communication services. The network node divides resource allocation into distinct categories: sensing-specific parameters (sensing QoS parameters) and communication parameters (communication QoS parameters), allowing optimized allocation for sensing without complicating the overall system architecture.
Solution Approach 2:
The patent implements a universal resource allocation framework where the network node handles both sensing and communication services through a single, unified interface. The same network node and signaling mechanisms (RRC connection, system information blocks) serve dual purposes, enabling multi-functionality without requiring separate dedicated systems for sensing services.
2Reliability
If generic resource allocation is applied to all services, then system operation is simplified, but sensing service performance deteriorates
Solution Approach 1:
The patent applies local quality by introducing sensing-specific QoS parameters that are tailored to the particular requirements of sensing services. Instead of uniform resource allocation, the system implements location-specific and service-specific parameter sets (e.g., sensing priority, sensing resource allocation) that optimize performance for sensing operations while maintaining simplicity in other areas.
Solution Approach 2:
The patent changes key parameters by introducing a dedicated sensing QoS parameter set that differs from traditional communication parameters. This includes modifying resource allocation parameters, priority levels, and QoS metrics specifically for sensing services, allowing the system to optimize sensing performance without fundamentally altering the overall operational framework.
3Reliability
If separate resource allocation mechanisms are created for sensing services, then sensing service quality is improved, but interference management deteriorates
Solution Approach 1:
The patent merges sensing service resource allocation with the existing communication resource allocation framework. By combining sensing QoS parameters with communication QoS parameters in a unified allocation mechanism, the system improves sensing service quality while maintaining coordinated interference management through the same network node that handles both service types.
Solution Approach 2:
The network node acts as an intermediary that coordinates resource allocation between sensing and communication services. It mediates potential interference by managing the interaction between sensing-specific parameters and communication parameters, ensuring that sensing service quality is enhanced while interference is controlled through centralized coordination.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a network node, a first request associated with establishing a sensing service, the first request including information indicating one or more requested sensing session parameters associated with the sensing service. The UE may receive, from the network node and based at least in part on the first request, a resource allocation for a virtual communication session, the resource allocation indicating one or more resources for the sensing service. Numerous other aspects are described.
