Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently selecting and managing resource pools for transmitting reference signals, particularly in advanced systems like 6G, which require high data rates, low latency, and reliable connectivity, leading to inefficiencies in resource allocation and positioning operations.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If sensing is performed in a single resource pool, then the device complexity is reduced, but the positioning accuracy and resource allocation efficiency deteriorate
Solution Approach 1:
The patent divides the resource pool into two distinct types: a first resource pool for transmitting first control information and a second resource pool for transmitting the first reference signal. This segmentation allows the device to perform sensing and resource selection separately for each pool type, improving positioning accuracy while managing complexity through structured division of resources.
Solution Approach 2:
The patent introduces a dual-resource-pool dimension to the traditional single-resource-pool approach. By adding this dimensional separation between control information resources and reference signal resources, the system achieves better positioning accuracy and resource allocation efficiency without overwhelming device complexity, as each dimension can be optimized independently.
2Productivity
If resource selection is optimized for high data rates, then the productivity increases, but the latency increases
Solution Approach 1:
The patent performs sensing operations in advance within defined resource selection windows before actual transmission. By conducting preliminary sensing and resource selection ahead of time, the system prepares candidate resource sets that can be quickly selected for transmission, thereby achieving high data rates while minimizing latency through pre-planned resource allocation.
Solution Approach 2:
The patent implements dynamic resource selection where candidate resource sets are determined based on real-time sensing results. The system can adaptively adjust resource allocation between the first and second resource pools based on channel conditions and traffic requirements, optimizing both productivity and latency through flexible, dynamic resource management rather than static allocation.
