PUCCH Resource Determination via Feedback Index
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G New Radio systems, base stations face challenges in accurately determining the Physical Uplink Control Channel (PUCCH) resource set used by terminals for feedback transmission, leading to comprehension differences between the base station and the terminal.
Innovation Solution
The method involves determining a target channel resource set based on the bit lengths of feedback information, where the first part of information has an invariable bit length and the second part has a variable bit length, allowing the terminal to select the appropriate PUCCH resource set for transmitting feedback information, and enabling the base station to align with the terminal's selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the base station configures multiple PUCCH resource sets through high-layer signaling, then the terminal can select appropriate resources for different feedback information sizes, but the base station cannot accurately learn which PUCCH resource set the terminal uses for feedback transmission
Solution Approach 1:
The patent applies feedback by having the terminal report the index of the determined PUCCH resource set to the base station. This feedback mechanism allows the base station to learn which resource set the terminal is using, resolving the information asymmetry while maintaining the adaptability of multiple resource sets.
Solution Approach 2:
The patent introduces an intermediary parameter (PUCCH resource set index) that bridges the terminal's resource selection and the base station's knowledge. By reporting this index, the terminal enables the base station to identify the selected resource set without directly exposing the selection logic.
2Quantity of substance
If the terminal determines PUCCH resource set based on feedback information bit length, then appropriate resources can be allocated for different feedback sizes, but different comprehension occurs between base station and terminal
Solution Approach 1:
The terminal provides feedback by reporting the PUCCH resource set index to the base station. This feedback ensures that the base station can accurately determine which resource set the terminal is using, aligning their comprehension despite different determination approaches.
Solution Approach 2:
The patent changes the parameter from direct resource set determination to index reporting. By using an index parameter that the terminal reports to the base station, the system maintains flexibility in determination methods while ensuring consistent understanding of the selected resource set.
