Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies struggle to determine remaining delay information of data in services like extended reality (XR) and cloud gaming, leading to reduced service capacity due to unsuccessful data transmission within required delay ranges.
Innovation Solution
A delay information management method that determines remaining delay information of data packets based on thresholds and parameters, allowing timely resource allocation to ensure data is transmitted within specified delay ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data transmission is attempted without accurate remaining delay information, then transmission may proceed, but service capacity is reduced due to unsuccessful transmissions outside delay ranges
Solution Approach 1:
The patent calculates remaining delay information in advance before data transmission occurs. By determining the remaining delay buffer time ahead of time, the system can proactively identify which data packets are at risk of exceeding delay requirements, allowing for preemptive resource allocation or packet prioritization to ensure timely delivery.
Solution Approach 2:
The patent establishes a feedback mechanism where the access network device receives remaining delay information from the terminal, processes this information to determine current delay status, and uses this feedback to dynamically adjust resource allocation. This closed-loop feedback enables continuous optimization of transmission timing to meet delay requirements.
2Reliability
If remaining delay information is accurately determined and used for resource allocation, then data transmission within delay ranges succeeds, but system complexity increases
Solution Approach 1:
The terminal device autonomously calculates its own remaining delay information based on local timing parameters and buffer status, then reports this information to the access network device. This self-service approach eliminates the need for complex centralized delay calculation mechanisms, reducing overall system complexity while maintaining accurate delay awareness.
Solution Approach 2:
The patent divides delay information management into distinct functional segments: the terminal calculates remaining delay based on local parameters (buffer status, transmission timing), the access network device receives and processes this segmented information, and each entity operates with clearly defined responsibilities. This segmentation simplifies the overall system architecture by avoiding the need for a single complex delay management mechanism.
3Speed
If resource allocation is delayed without timely delay information, then resource allocation is simpler, but data transmission fails to meet delay requirements
Solution Approach 1:
The system calculates remaining delay information in advance before resource allocation decisions are made. By knowing the remaining delay buffer time ahead of time, the access network device can proactively allocate resources to data packets that are approaching their delay deadlines, ensuring high-speed transmission before the delay buffer is exhausted.
Solution Approach 2:
The feedback loop provides real-time delay status information to the resource allocation mechanism, enabling dynamic adjustment of transmission priority and resource assignment. This feedback ensures that data packets with shrinking delay buffers receive timely resource allocation to maintain transmission speed within acceptable delay ranges.

AI summary
This application provides a delay information management method and a related apparatus, and relates to the wireless communication field. The method includes: obtaining first delay information of a first granularity, and reporting the first delay information. The first delay information is used for indicating a remaining sending delay of the first granularity or a remaining sending delay of a data packet of the first granularity. In this way, an access network device can sense remaining delay information of a specified service on a terminal, to allocate a resource to data with a small remaining delay in a timely manner, so that the data can be transmitted to the access network device within a required delay range.
