Integrated Sensing Communication Resource Grouping

Solution Overview

Problem

Current integrated sensing and communication systems in mobile communication face challenges in efficiently utilizing resources for both communication and sensing purposes, particularly in optimizing resources for different objectives such as received signal strength and sensing accuracy.

Innovation Solution

The system employs an apparatus that broadcasts reference signals using multiple resources as part of a beam sweeping algorithm, receives information on preferred resources for communication and sensing from communication nodes and objects respectively, and forms groups based on these optimal resources. It then defines resources for each group to maximize either communication or sensing objectives while meeting the other's requirements.

1Productivity

If resources are allocated to maximize communication objectives (data transfer), then communication performance is improved, but sensing performance deteriorates

Engineering Contradiction:

Improvedata transfer rateVSAvoidsensing accuracy

Core Design Contradiction:

ProductivityVSMeasurement precision

Solution Approach 1:

The system segments communication nodes and objects into different groups based on their resource preferences. Communication nodes are grouped with objects that share similar optimal resource characteristics, allowing dedicated resource allocation for each group. This segmentation enables simultaneous optimization of communication and sensing for different groups without mutual interference.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system changes resource parameters (time-frequency resources, beam directions) based on the specific group being served. By dynamically adjusting resource allocation parameters according to group characteristics and objectives, the system can maximize data transfer for communication groups while maintaining adequate sensing performance for sensing groups.
