AI Technical Summary
Technical Problem
The high radio resource consumption in mmWave beam sweeping for sensing in Integrated Sensing and Communication (ISAC) systems, primarily due to wide bandwidth, multiple OFDM symbols, periodic transmission, and sharp sensing beams, leads to inefficiencies and resource overhead.
Method used
A multi-stage beam sweeping procedure with adaptive sensing resource allocation, including an initial wide-area search for qualitative detection and follow-up refined stages to optimize resource usage based on historical data and environmental conditions.
Benefits of technology
This approach reduces sensing overhead while maintaining accuracy by efficiently allocating resources where needed, balancing the need for precise sensing with resource limitations.

Abstract
A method and a device for improved object sensing are disclosed. The method for object sensing includes: triggering a first object sensing procedure; determining whether or not one or more sensing requirements for an object sensed in the first object sensing procedure are met; and triggering a second object sensing procedure for the object in response to determining that the one or more sensing requirements are not met.
