Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, particularly in supporting Extended Reality (XR) services, determining whether a PUSCH is transmitted in a target radio resource pool is a key issue, and existing methods face challenges in improving UCI feedback performance, transmission efficiency, and reducing detection complexity.
Innovation Solution
A method involving a first node that receives signaling to determine a target radio resource pool and transmits information indicating whether a PUSCH is transmitted, based on conditions related to resource overlap and specific UCI characteristics, ensuring accurate transmission and reception of PUSCH in the target pool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing methods are used to determine PUSCH transmission in target radio resource pool, then system operation is maintained, but UCI feedback performance is insufficient and detection complexity is high
Solution Approach 1:
The patent segments the determination of PUSCH transmission into distinct conditions: checking whether the target radio resource pool overlaps with characteristic resources, and evaluating the first information indicating PUSCH transmission. This segmentation allows the base station to process each condition independently, reducing detection complexity while improving feedback performance.
Solution Approach 2:
The patent performs preliminary checks before PUSCH transmission determination by first identifying overlapping between target radio resource pool and characteristic resources, and preparing the first information about UCI multiplexing. This preliminary action enables the base station to make informed decisions without complex real-time analysis, reducing detection complexity.
2Productivity
If PUSCH transmission is determined without considering resource overlap and UCI characteristics, then transmission process is simple, but transmission performance and resource utilization are poor
Solution Approach 1:
The patent introduces dynamic determination of PUSCH transmission based on multiple factors: the overlap between target radio resource pool and characteristic resources, and the first information about UCI multiplexing. This dynamic approach allows the system to adapt transmission decisions to current resource conditions, improving transmission efficiency without requiring overly complex static designs.
Solution Approach 2:
The patent changes the parameters used for PUSCH transmission determination from simple on/off decisions to multi-parameter evaluation including resource pool overlap characteristics and UCI multiplexing status. This parameter expansion enables more efficient resource utilization while maintaining manageable system complexity through structured evaluation criteria.
3Ease of operation
If communication parties use different criteria to determine PUSCH transmission, then individual decision-making is simple, but inconsistent understanding occurs between communication parties
Solution Approach 1:
The patent establishes a universal determination criterion that both user equipment and base station apply: check for overlap between target radio resource pool and characteristic resources, and evaluate the first information about UCI multiplexing. This universal approach ensures consistent understanding between communication parties while keeping individual decision-making simple through standardized evaluation steps.
Solution Approach 2:
The patent uses the first information as feedback from user equipment to the base station regarding UCI multiplexing status. This feedback mechanism ensures both parties have consistent information for determination, preventing inconsistent understanding while maintaining simple decision-making through clear information exchange protocols.
4Measurement precision
If delayed PUSCH transmission determination is performed, then comprehensive analysis is possible, but delay requirements of services cannot be met
Solution Approach 1:
The patent performs preliminary identification of resource pool overlaps and prepares first information about UCI multiplexing before PUSCH transmission decisions are required. This preliminary action enables comprehensive analysis to be completed in advance, ensuring both accurate determination and timely service delivery without compromising either analysis accuracy or meeting delay requirements.
