Bidirectional Latency Correlation for XRM Service Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication networks lack an effective mechanism to coordinate and adjust latency parameters of uplink and downlink transmissions for extended reality multimedia (XRM) services, failing to meet the bidirectional latency requirements and ensuring successful service transmission.
Innovation Solution
A correlation identifier (ID) is used to correlate the transmission latency parameters of uplink and downlink transmissions, enabling network elements to adjust and coordinate latency parameters based on real-time network conditions, thereby improving the efficiency and success rate of XRM service delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate latency parameters are used for uplink and downlink transmissions, then each direction can be independently controlled, but the bidirectional latency coordination fails and service transmission success rate decreases
Solution Approach 1:
The patent merges separate uplink and downlink latency parameters into a unified bidirectional latency management framework by introducing a correlation identifier that links latency parameters of both directions. This allows the network to coordinate and adjust latency parameters jointly, ensuring that bidirectional latency requirements are met while maintaining the ability to independently control each direction when needed.
2Device complexity
If no correlation mechanism is introduced, then system complexity remains low, but latency parameter coordination between uplink and downlink cannot be achieved
Solution Approach 1:
The patent introduces a correlation identifier as an intermediary element that connects uplink and downlink latency parameters without significantly increasing system complexity. This correlation identifier acts as a mediator that enables precise coordination of latency parameters by providing a reference link between the two directions, allowing the network to achieve accurate latency coordination with minimal additional complexity.
3Reliability
If real-time latency monitoring and adjustment is implemented, then bidirectional latency requirements can be met, but network control complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where the network monitors latency parameters of uplink and downlink transmissions in real-time and uses the correlation identifier to coordinate adjustments. When latency deviations are detected, the network can trigger re-adjustment of latency parameters based on the correlated relationship, ensuring bidirectional latency requirements are met while managing control complexity through structured feedback loops.

AI summary
Embodiments of the present disclosure relate to an information transmission method and apparatus, a communication device, and a storage medium. A policy control function (PCF) determines and sends an association identifier of a predetermined service, the association identifier being used for associating a transmission delay parameter for uplink transmission and a transmission delay parameter for downlink transmission of a predetermined service data stream.
