Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication networks face limitations in performance due to fixed timing relationships in HARQ feedback, which can lead to inefficiencies in data transmission and processing delays.
Innovation Solution
A method is introduced where a radio network node determines a dynamic delay value for data transmission based on the transmission type or the capability of the wireless device, and communicates this delay value to the device, allowing for adjusted scheduling of data transmissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If fixed timing relationships are used in HARQ feedback, then network simplicity is maintained, but transmission efficiency deteriorates due to processing delays
Solution Approach 1:
The patent applies dynamics by transitioning from fixed timing relationships to dynamic delay values for HARQ feedback. The network node determines delay values based on transmission type and device capability, allowing the timing to adapt to different scenarios rather than following a rigid fixed schedule, thereby improving transmission efficiency without excessive complexity
Solution Approach 2:
The patent changes the timing parameter from fixed to variable by introducing dynamic delay values. The delay value becomes a configurable parameter that can be adjusted based on transmission type (e.g., ultra-reliable low-latency communication vs. enhanced mobile broadband) and device processing capability, optimizing transmission efficiency for different service requirements
2Productivity
If dynamic delay values are implemented, then transmission efficiency is improved, but device complexity increases due to capability reporting requirements
Solution Approach 1:
The patent introduces capability indication parameters that allow devices to report their processing capabilities to the network. This enables the network to determine appropriate dynamic delay values matched to the device's actual processing ability, improving overall network performance while keeping the complexity manageable through standardized parameter exchange
Solution Approach 2:
The patent implements a feedback mechanism where devices report their processing capabilities to the network node. This feedback loop enables the network to make informed decisions about delay values, matching the scheduling to actual device capabilities rather than using one-size-fits-all timing, thereby improving network performance
3Loss of time
If processing time is reduced for faster transmission, then latency is decreased, but processing accuracy deteriorates
Solution Approach 1:
The patent applies local quality by differentiating delay requirements based on transmission type and device capability. Different parts of the system (different device types, different transmission scenarios) receive locally optimized delay values rather than a uniform timing approach, allowing each to operate at its optimal processing speed while maintaining required accuracy
Solution Approach 2:
The patent changes the delay parameter dynamically based on the specific transmission scenario and device capability. By adjusting the delay value parameter to match the actual processing requirements of each device and transmission type, the system achieves the minimum necessary processing time without excessive delays, optimizing both latency and reliability

AI summary
Embodiments herein relate to a method performed by a radio network node for handling transmission of data from a wireless device in a wireless communication network. The radio network node determines a delay value for a transmission of data from the wireless device based on a transmission type of data from the wireless device or a capability of the wireless device. The capability is related to a processing time for processing received data from the radio network node, or for processing data for transmission to the radio network node. The radio network node further transmits an indication, to the wireless device, which indication indicates the determined delay value.
