PUCCH Transmission with Dynamic Activation Parameter Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G mobile communications systems, the lack of clarity on which activation parameter to use for PUCCH transmission on a PUCCH resource configured by the network device leads to inefficiencies and potential miscommunication, as conventional technologies allow only a single activation parameter per resource, unclear in usage.
Innovation Solution
A method for determining a target parameter for PUCCH transmission by selecting one of multiple activation parameters based on specific conditions or network device indications, ensuring consistent and reliable communication by reducing network resource overheads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If one PUCCH resource is configured with multiple activation parameters, then the adaptability and versatility of the resource are improved, but the device complexity and difficulty of parameter selection increase
Solution Approach 1:
The patent implements dynamic parameter selection where the target activation parameter is determined based on real-time conditions such as the type of downlink control information, the serving cell index, or network device indications. This allows the system to adaptively choose the appropriate activation parameter (first or second) at the time of PUCCH transmission, resolving the contradiction by making the parameter selection process dynamic rather than static, thus improving adaptability while managing complexity through structured selection criteria.
Solution Approach 2:
The patent changes the state of the PUCCH resource configuration from having a single fixed activation parameter to having multiple activation parameters (first and second activation parameters) that can be selectively applied. This parameter change enables the system to handle different transmission scenarios with appropriate parameters, improving versatility while the structured selection mechanism based on DCI type or network indication manages the complexity of having multiple parameters.
2Reliability
If multiple activation parameters are allowed per PUCCH resource, then communication reliability is improved through better parameter matching, but the loss of information increases due to ambiguity in parameter selection
Solution Approach 1:
The patent incorporates feedback mechanisms where the network device can provide indications to the terminal device about which activation parameter to use. This feedback loop ensures that both the network and terminal have consistent understanding of the parameter selection, preventing information loss and ambiguity. The feedback may come in the form of DCI content analysis, serving cell index information, or explicit network device indications, ensuring reliable parameter usage.
Solution Approach 2:
The patent establishes predetermined rules and criteria for selecting between the first and second activation parameters before actual PUCCH transmission occurs. These preliminary actions include defining selection based on DCI type, serving cell index, or other pre-agreed criteria, which eliminates ambiguity at the time of transmission. By having the selection logic prepared in advance, the system maintains clear parameter usage understanding while enabling reliable transmission.
3Ease of operation
If a single activation parameter is used per PUCCH resource, then the ease of operation is maintained, but the productivity and efficiency of resource utilization decrease
Solution Approach 1:
The patent segments the activation parameter selection into distinct cases or categories, such as different DCI types (first type vs. second type), different serving cell indices, or different PUCCH resource types. This segmentation allows the system to maintain simple operation within each segment while achieving high overall efficiency through appropriate parameter selection for each segment. The segmentation approach keeps the operation easy by providing clear decision boundaries while maximizing productivity through optimized parameter usage for different scenarios.
