Uplink Channel Multiplexing for Priority-Based Latency Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for high data throughput and communication capacity in wireless communication systems, particularly due to the rise of M2M communication and high-density user equipment, poses challenges in efficiently managing limited radio resources and reducing latency in next-generation communication systems.
Innovation Solution
A method for determining and transmitting uplink channels with different priorities in a wireless communication system, where channels that do not satisfy a multiplexing timeline condition are identified, and only the highest priority non-overlapping channel is transmitted, optimizing resource usage and reducing latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple uplink channels with different priorities are transmitted simultaneously, then communication capacity increases, but resource collision and interference occur
Solution Approach 1:
The patent segments uplink channels by priority levels (first priority and second priority channels) and applies different transmission rules to each segment. High-priority channels are transmitted without multiplexing checks, while low-priority channels are subject to multiplexing timeline conditions, resolving the contradiction by allowing high productivity for urgent traffic while maintaining reliability for standard traffic.
Solution Approach 2:
The patent changes the parameter of multiplexing timeline condition satisfaction based on channel priority. When a high-priority channel is detected, the system adjusts the multiplexing condition parameter to be less restrictive, allowing transmission without checking timeline conditions. This dynamic parameter adjustment enables simultaneous transmission of multiple channels while maintaining resource allocation reliability through priority-based differentiation.
2Reliability
If uplink channels are multiplexed according to strict timeline conditions, then resource allocation reliability improves, but transmission latency increases
Solution Approach 1:
The patent implements dynamic transmission rules where the multiplexing timeline condition check is applied selectively based on channel priority and timing. For high-priority channels or when timing constraints are tight, the system dynamically bypasses the multiplexing check to reduce latency. This dynamic approach maintains reliability for non-urgent traffic while minimizing time loss for urgent transmissions.
3Productivity
If all overlapping uplink channels are transmitted, then data throughput increases, but resource collision and interference increase
Solution Approach 1:
The patent applies different transmission qualities and rules to different priority channels. High-priority channels receive preferential treatment with relaxed multiplexing conditions, while low-priority channels undergo strict multiplexing timeline checks. This local quality differentiation allows the system to maximize throughput for critical data while preventing resource collisions through controlled transmission of non-critical data.

AI summary
A UE may comprise: determining that uplink channels with different priorities overlap with respect to time; determining whether the uplink channels with the different priorities satisfy multiplexing timeline conditions; determining, on the basis of the non-satisfaction of the multiplexing timeline conditions by the uplink channels with different priorities, an uplink channel to be multiplexed, for uplink channels with the highest priority, that satisfy the multiplexing timeline conditions, from among the different priorities; and transmitting the uplink channel to be multiplexed.
