Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing New Radio (NR) systems lack flexibility in time resource allocation, as terminal devices always use a single type of time unit for transmitting uplink information, such as periodic CSI, which restricts system performance.
Innovation Solution
A method where a terminal device determines and uses different transmission manners for target uplink information in different time units, allowing for varied preprocessing methods, transmission modes, frequency-domain resources, transmit power, and resource indices, thereby enhancing flexibility in time resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a terminal device always adopts a single type of time unit to transmit uplink information, then the transmission process is simple and stable, but the flexibility of time resource allocation in the system deteriorates
Solution Approach 1:
The patent applies dynamics by enabling the terminal device to dynamically select between different transmission manners (first transmission manner with longer time duration and second transmission manner with shorter time duration) based on real-time channel conditions and service requirements. This dynamic adaptation allows the system to flexibly allocate time resources while managing complexity through condition-based selection rules
Solution Approach 2:
The patent changes the transmission parameters by introducing multiple transmission manners with different time durations. The terminal device can switch between the first transmission manner (longer duration, better coverage) and the second transmission manner (shorter duration, higher efficiency) by changing transmission parameters such as time duration, preprocessing methods, and resource allocation based on channel quality and service type
2Productivity
If different transmission manners are used in different time units, then the flexibility of time resource allocation is improved, but the complexity of determining transmission manners increases
Solution Approach 1:
The patent applies local quality by allowing different transmission manners to be applied in different time units based on local channel conditions and service requirements. Each time unit can independently select the appropriate transmission manner (first or second) according to its specific needs, optimizing system performance locally while contributing to overall productivity
Solution Approach 2:
The system dynamically adjusts transmission manners in different time units based on real-time conditions. The terminal device determines whether to use the first transmission manner (with longer duration and enhanced coverage) or the second transmission manner (with shorter duration and higher efficiency) based on channel quality, service type, and other time-varying parameters
3Reliability
If a longer time length is used for transmission, then the transmission coverage is improved, but the transmission efficiency deteriorates
Solution Approach 1:
The patent resolves this contradiction by making the transmission time length dynamic. The terminal device can select the first transmission manner with longer time duration when coverage is the priority (poor channel conditions), and switch to the second transmission manner with shorter time duration when efficiency is the priority (good channel conditions), thus adapting to different operational requirements
Solution Approach 2:
The patent changes the transmission parameter of time duration by introducing two distinct transmission manners. The first transmission manner uses a longer time length to improve coverage and reliability, while the second transmission manner uses a shorter time length to improve efficiency. The system changes between these parameter configurations based on channel conditions and service requirements
