Uplink Control Resource Selection for Variable XR Frame Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for uplink data transmission in 5G communication systems do not adequately consider the varying frame sizes of XR video frames, leading to inefficiencies in resource allocation and reliability of control information transmission.
Innovation Solution
Determine a resource for transmitting control information based on a first parameter that includes the number of bits of the control information, allowing for improved reliability of uplink data transmission by optimizing the use of physical uplink shared channels in configured grant periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed uplink scheduling resource is used for transmitting XR video frames, then the resource allocation is simple, but the reliability of control information transmission deteriorates due to varying frame sizes
Solution Approach 1:
The patent applies dynamics by making the resource allocation adaptive rather than fixed. The terminal device dynamically determines the first resource for transmitting control information based on the number of bits of the control information, allowing the system to adapt to varying XR video frame sizes while maintaining simple overall resource allocation mechanisms
Solution Approach 2:
The patent changes the parameter of resource selection based on the number of bits of control information. By selecting resources according to the bit length parameter, the system optimizes transmission reliability without significantly increasing allocation complexity, resolving the contradiction between simplicity and reliability
2Reliability
If the number of bits of control information is increased to improve transmission reliability, then the reliability improves, but the resource consumption increases
Solution Approach 1:
The patent optimizes the parameter of control information bit length and selects resources accordingly. By adjusting the number of bits based on actual transmission needs and matching it with appropriate resources, the system achieves reliable transmission without excessive resource consumption
Solution Approach 2:
The patent applies partial action by transmitting only the necessary control information bits required for reliable transmission. The terminal device determines the appropriate number of bits and selects corresponding resources, avoiding excessive resource consumption while ensuring sufficient reliability
3Reliability
If rate matching solution is implemented for UCI indicating information about uplink transmission, then the reliability improves, but the device complexity increases
Solution Approach 1:
The patent segments the control information transmission into two parts: first control information (UCI) and second control information (HARQ feedback). This segmentation allows the system to handle different types of control information separately, improving reliability without significantly increasing overall complexity
Solution Approach 2:
The patent makes the resource allocation dynamic by having the terminal device determine the first resource based on the number of bits of the first control information. This dynamic approach allows the system to adapt to different transmission scenarios while maintaining manageable complexity through structured decision-making
