Multiplexing Control Information on Common Transmission Resource
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern wireless communication systems face challenges in efficiently managing uplink transmission resources, particularly when handling multiplexed transmissions with different priorities or qualities, such as URLLC and eMBB, which can lead to self-interference and inefficient resource utilization.
Innovation Solution
A method and device for multiplexing control information on a common transmission resource, selecting it based on payload size and transmission quality, to avoid multiple transmissions and optimize resource usage, while prioritizing urgent control information for quick demodulation and decoding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate transmissions are used for different control information, then each transmission can be optimized for its specific requirements, but self-interference increases and resource utilization becomes inefficient
Solution Approach 1:
The patent combines multiple control information transmissions into a single multiplexed transmission on a common resource. Different control information items are multiplexed in the time domain within the same time resource, allowing multiple transmissions to occur simultaneously without causing self-interference while improving resource utilization efficiency.
2Reliability
If multiple separate transmissions are used for different control information, then transmission requirements can be met individually, but resource utilization becomes inefficient
Solution Approach 1:
The patent merges multiple control information items onto a single common transmission resource, combining what would otherwise be separate transmissions into one unified transmission event. This reduces the total number of transmissions required and improves resource utilization efficiency while maintaining the ability to meet individual transmission quality requirements through multiplexing.
Solution Approach 2:
The common transmission resource serves multiple functions by accommodating different control information items simultaneously. The single resource structure can carry multiple control information types with different priorities and requirements, making the system more versatile and efficient.
3Productivity
If control information is multiplexed on a common resource, then resource utilization improves and self-interference reduces, but additional control signaling overhead may be required
Solution Approach 1:
The patent employs self-service mechanisms where the control information items themselves carry indicators that enable the receiver to identify and process the different control information types without requiring additional external signaling. The multiplexed transmission structure inherently provides the necessary identification information through the transmission characteristics and resource allocation patterns.
