Uplink Resource Selection Using Indexed Candidate Resources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems, particularly in 5G, face challenges in achieving low-delay data transmission for extended reality (XR) applications due to complex interaction processes involving SR and BSR reporting, leading to ineffective data transmission solutions.
Innovation Solution
A method where a terminal device selects a first resource from M candidate resources and indicates its index to the network device, reducing transmission delay and network device complexity by avoiding blind detection, while ensuring efficient resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the terminal device performs SR reporting and BSR reporting before data transmission, then the resource allocation can be scheduled, but the transmission delay increases and low-delay requirement cannot be met
Solution Approach 1:
The network device pre-configures M candidate resources for the terminal device before actual data transmission is needed. This preliminary resource preparation eliminates the need for real-time SR and BSR reporting procedures, allowing the terminal to directly use preallocated resources for low-delay transmission.
Solution Approach 2:
The patent extracts and removes the complex SR and BSR reporting procedures from the data transmission process. By separating these scheduling operations from the actual data transmission, the system achieves low-delay performance while maintaining resource allocation effectiveness.
2Measurement precision
If the network device performs blind detection on M candidate resources to find the first resource, then the resource can be accurately identified, but the communication complexity of the network device increases
Solution Approach 1:
The terminal device provides feedback by indicating the index of the selected first resource among the M candidate resources. This feedback mechanism guides the network device to the correct resource without requiring blind detection, significantly reducing network processing complexity while maintaining accurate resource identification.
Solution Approach 2:
The resource index indication acts as an intermediary between the terminal's resource selection and the network's resource identification. Instead of the network performing complex blind detection, the index indication serves as a simple mediator that directly points to the correct resource.
3Adaptability or versatility
If multiple candidate resources are configured for the terminal device, then resource selection flexibility is improved, but the complexity of determining the first resource increases
Solution Approach 1:
The patent segments the resource configuration into M distinct candidate resources, each with a unique index. This segmentation allows the terminal to flexibly select the most appropriate resource while simplifying the determination process through clear index-based identification rather than complex analysis.
Data Source
AI summary
A terminal device receives, from a network device, first configuration information, where the first configuration information is used to configure M candidate resources, and M is an integer greater than 1. The terminal device sends to the network device, indication information, where the indication information carries an index of a first resource in the M candidate resources, and the first resource is used to send uplink information. The terminal device performs uplink transmission by using the first resource in the M candidate resources, so that a transmission delay is reduced. Further, the terminal device indicates the index of the first resource to a network device by using the indication information.
