PUCCH Overlap Handling via Deterministic Priority Checking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication technologies, determining the correct PUCCH to transmit in overlapping time domain units is challenging due to varying priority levels, leading to inconsistent checking results and potential missed receptions, affecting communication quality between user devices and base stations.
Innovation Solution
Preset characteristic parameters are used to determine a checking order for PUCCHs, ensuring a deterministic checking result, which allows user devices and base stations to accurately identify the target PUCCH for transmission, thereby ensuring reliable communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple groups of overlapping PUCCHs are handled by determining priority levels based on different orders, then the flexibility in handling overlapping PUCCHs increases, but the checking results become inconsistent and unreliable
Solution Approach 1:
The patent applies parameter changes by establishing a deterministic checking order based on PUCCH group indices and priority levels. Instead of using different orders for different groups, the system uses a consistent parameter (group index combined with priority level) to determine the checking sequence, ensuring that the same input always produces the same output while maintaining the ability to handle multiple overlapping groups.
2Reliability
If a deterministic checking order is established for all PUCCH groups, then the checking results become consistent and reliable, but the complexity of determining the checking order increases
Solution Approach 1:
The patent segments the PUCCH groups and applies a systematic checking approach by dividing them into individual groups with specific indices. Each group is processed independently with a determined checking order, which simplifies the overall complexity while ensuring consistency. The segmentation allows the system to handle multiple groups without requiring a single complex global ordering mechanism.
Solution Approach 2:
The patent applies preliminary action by pre-determining the checking order for each PUCCH group based on their indices and priority levels before actual transmission occurs. This advance determination ensures that both the user device and base station have the same understanding of which PUCCH to transmit and receive, eliminating ambiguity without requiring complex real-time decision-making during transmission.
3Measurement precision
If the base station uses the same checking order as the user device, then the base station can accurately determine which PUCCH to receive, but requires knowledge of the user device's determination process
Solution Approach 1:
The patent applies universality by establishing a standardized checking order mechanism that serves both the user device and base station. The same rules and parameters (PUCCH group indices, priority levels, and checking sequences) are applied at both ends, making the system self-sufficient. The base station independently determines the checking order using the same criteria as the user device, eliminating the need for explicit information exchange about the checking process while ensuring accurate PUCCH identification.

AI summary
An embodiment of the present disclosure provides a method for determining a PUCCH requiring transmission, the method comprising: determining multiple PUCCHs coinciding in a me-domain unit; determining an identification order of the PUCCHs according to a pre-determined feature parameter of the PUCCHs; identifying the multiple PUCCHs one by one according to the identification order, and identifying a relationship between the priority levels of other PUCCHs coinciding with a current PUCCH undergoing identification in the time-domain unit and a priority level of said current PUCCH undergoing identification; and determining a target PUCCH requiring transmission in the time-domain unit according to an identification result, and ignoring other PUCCHs coinciding with the target PUCCH. The embodiment of the present disclosure guarantees that a PUCCH transmitted by a user equipment unit can be correctly received by a base station, thereby ensuring excellent communication quality between the user equipment unit and the base station.
