Uplink Data Transmission QoS Alignment in Wireless Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, the inconsistency between the Quality of Service (QoS) level of uplink data scheduled by a UL grant and the QoS level of data transmitted by User Equipment (UE) leads to reduced data transmission rate and reliability, affecting efficiency.
Innovation Solution
The UE determines the target QoS level indicated by the UL grant and acquires corresponding data to ensure that the transmitted data has a consistent QoS level, aligning it with the scheduled QoS, and transmits it through the allocated resource.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If UE transmits multiple pieces of UL data in sequence from high to low QoS levels based on UL grant, then all UL data can be transmitted using the allocated resource, but the data transmission rate and reliability are reduced when QoS levels are inconsistent
Solution Approach 1:
The patent segments the transmission process into two distinct parts: first transmitting data with QoS level matching the scheduled QoS level, then transmitting remaining data with lower QoS levels. This segmentation ensures that critical data meeting the scheduled QoS requirements is transmitted with appropriate reliability guarantees, while non-critical data utilizes remaining resources, thereby resolving the contradiction between transmission rate and reliability.
Solution Approach 2:
The patent applies different transmission qualities to different portions of data based on their QoS requirements. The first part of data (matching scheduled QoS) receives full quality treatment with appropriate modulation and coding schemes, while the second part (lower QoS) uses simplified transmission. This local quality differentiation maintains high reliability for critical data while improving overall transmission efficiency.
2Productivity
If UE transmits data with QoS level inconsistent with scheduled QoS level, then transmission resource can be fully utilized, but the data transmission efficiency is affected
Solution Approach 1:
The patent performs preliminary action by first identifying and transmitting data whose QoS level matches the scheduled QoS level before transmitting other data. This preliminary sorting and selective transmission ensures that data requiring specific QoS guarantees is handled first with appropriate transmission parameters, thereby maintaining QoS level consistency while improving overall transmission efficiency.
Solution Approach 2:
The patent introduces dynamic adaptation by adjusting transmission parameters based on the QoS level of each data portion. The first data portion uses transmission parameters matched to the scheduled QoS level, while the second portion uses parameters optimized for its lower QoS requirements. This dynamic parameter adjustment resolves the contradiction between efficiency and QoS consistency.
