Solution Overview
Problem
There is no clear solution in existing technologies for performing long NR-PUCCH transmission in multiple slots within the 5G NR system, which is necessary for improving uplink coverage.
Innovation Solution
A method for determining the total transmission length and structure of the uplink control channel (PUCCH) to be transmitted in multiple slots, where the transmission structure is determined based on the total transmission length, allowing the PUCCH to be transmitted effectively across multiple slots, with the base station receiving the PUCCH according to this structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If long NR-PUCCH is transmitted in multiple slots, then uplink coverage is improved, but there is no clear solution or standard for how to perform the transmission
Solution Approach 1:
The patent segments the long NR-PUCCH transmission into multiple slots, where each slot contains a specific number of symbols configured for PUCCH transmission. This segmentation allows the uplink control channel to be distributed across multiple time slots, improving coverage while providing a structured approach to manage the complexity of multi-slot transmission.
2Adaptability or versatility
If the number of uplink symbols in a slot changes, then slot structure flexibility is improved, but it becomes difficult to determine the total transmission length of PUCCH across multiple slots
Solution Approach 1:
The patent applies preliminary action by configuring the number of symbols for PUCCH transmission in advance through RRC signaling or other pre-configuration methods. This allows the terminal to know beforehand how many symbols are allocated for PUCCH in each slot, enabling accurate determination of the total transmission length across multiple slots despite variations in slot structures.
3Reliability
If long NR-PUCCH transmission in multiple slots is implemented, then uplink coverage is improved, but the transmission structure and resource allocation become uncertain
Solution Approach 1:
The patent incorporates feedback mechanisms where the network configures PUCCH transmission parameters through RRC signaling, and the terminal provides feedback regarding the configured parameters. This feedback loop ensures that both the network and terminal have consistent understanding of the transmission structure, making multi-slot long PUCCH transmission operations straightforward and reliable.
