Dynamic Resource Indication for XR Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Extended reality (XR) services, such as augmented reality (AR), virtual reality (VR), and cloud gaming (CG), require ultra reliability and low latency, but they often result in resource waste during data transmission due to their pseudo-periodic nature, variable packet sizes, and non-integer service periods.
Innovation Solution
A data transmission method where a first device sends indication information to a second device to determine whether to use a target resource for data transmission, allowing the second device to properly schedule transmission resources based on the indication information, thereby optimizing resource utilization.

Engineering Contradiction Analysis
1Reliability
If resources are allocated for XR services with pseudo-periodic nature and variable packet sizes, then ultra reliability and low latency are achieved, but resource waste occurs
Solution Approach 1:
The patent implements dynamic resource allocation by allowing the first device to send indication information that dynamically adjusts whether the second device uses target resources for data transmission. This dynamic adjustment mechanism enables resources to be allocated based on actual service needs rather than fixed periodic allocation, achieving ultra reliability when needed while avoiding resource waste during low-traffic periods.
Solution Approach 2:
The patent changes the parameter of resource allocation from static periodic allocation to dynamic allocation based on indication information. By modifying the allocation parameter according to actual service requirements (variable packet sizes and arrival times), the system achieves both high reliability for critical transmissions and efficient resource utilization by avoiding allocation during unnecessary periods.
2Productivity
If resources are allocated based on fixed periodic intervals, then resource scheduling is simplified, but resource utilization efficiency decreases due to variable packet sizes and non-integer periods
Solution Approach 1:
The patent applies preliminary action by having the first device send indication information in advance to inform the second device about upcoming data transmission needs. This advance notification allows the second device to prepare and allocate resources appropriately before actual transmission occurs, improving resource utilization efficiency while maintaining manageable scheduling complexity through predetermined indication mechanisms.

AI summary
This application relates to a data transmission method and apparatus, a computer device, and a storage medium. A first device (01) sends indication information to a second device (02), so that the first device (01) informs the second device (02) of a usage status of a target resource in time, and after receiving the indication information, the second device (02) may determine, based on the indication information, which resources to use, which resources to receive or decode, which resources not to receive or decode, which resources to terminate, and the like.
