The specification describes an apparatus comprising a sensing management function (SeMF) that receives sensing service requests from clients, selects between monostatic and multi-static sensing methods, and configures radio access network nodes accordingly to perform sensing operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If monostatic sensing is used with a single radio access network node for transmission and reception, then device complexity is reduced, but sensing accuracy and coverage are limited
Solution Approach 1:
The patent combines multiple radio access network nodes into a coordinated sensing system. Multiple nodes work together in a multi-static sensing configuration where some nodes transmit sensing signals and others receive them, creating a distributed sensing network that improves accuracy while managing complexity through coordination protocols
2Measurement precision
If multi-static sensing with multiple radio access network nodes is used, then sensing accuracy and coverage are improved, but device complexity increases
Solution Approach 1:
The patent introduces a sensing management function as an intermediary that coordinates between multiple radio access network nodes. This mediator manages the complexity by handling signal coordination, resource allocation, and data fusion, allowing multiple nodes to work together effectively without requiring complex peer-to-peer interactions between all nodes
3Adaptability or versatility
If sensing services are added to wireless communication systems, then functionality and versatility are improved, but resource management complexity increases
Solution Approach 1:
The patent implements a universal sensing management function that handles multiple sensing service types and configurations through a single standardized interface. This multi-functional approach allows the system to support diverse sensing applications (object detection, tracking, classification) while managing resources through unified protocols, reducing the complexity that would arise from separate specialized systems

AI summary
A method, apparatus and computer program is described comprising: receiving, from a sensing client of a wireless communication system, a sensing service request including information related to a sensing service, requested by the sensing client, to be provided by the sensing management function; selecting, based, at least in part, on the information related to the sensing service, one of: monostatic sensing for the sensing service, in which a first selected radio access network node is used for transmission and reception of radio signals used for sensing, and multi-static sensing, in which one selected radio access network node is used for transmission of radio signals for sensing and one or more other selected radio access nodes are used for reception of radio signals used for sensing.
