PUCCH Frequency Hopping Interval Configuration via Time Domain Window
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems, such as those in the 3GPP's LTE and New Radio (NR) standards, face inefficiencies in managing PUCCH transmission and reception, particularly in configuring frequency hopping intervals and time domain windows, which affect overall communication performance.
Innovation Solution
The implementation of a terminal apparatus and base station apparatus that configure PUCCH formats with higher layer parameters for frequency hopping, where the hopping interval is determined based on a time domain window, and defaults to one slot if no window is configured, optimizing communication efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If frequency hopping is configured for PUCCH transmission, then communication reliability is improved through frequency diversity, but device complexity increases due to additional configuration parameters and processing
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the frequency hopping interval based on the time domain window configuration. When a time domain window is configured, the hopping interval is set to match this window; otherwise, it defaults to one slot. This adaptive parameter adjustment optimizes frequency diversity gains while managing device complexity through conditional configuration rather than fixed complex mechanisms.
2Productivity
If a time domain window is configured for PUCCH format, then communication efficiency is improved through optimized resource allocation, but device complexity increases due to additional configuration management
Solution Approach 1:
The patent implements dynamics by making the frequency hopping interval adaptive rather than fixed. The hopping interval dynamically adjusts based on whether a time domain window is configured and what its duration is. This dynamic behavior allows the system to optimize communication efficiency under different configuration scenarios while avoiding the need for permanently complex device logic for all possible cases.

AI summary
A terminal apparatus includes a receiver configured to receive a PDCCH including a DCI format indicating transmission of a PUCCH, and a transmitter configured to transmit the PUCCH. In a case that a higher layer parameter InterSlotFrequencyHopping is configured for a PUCCH format corresponding to the PUCCH to perform frequency hopping and a length of a time domain window is configured by a higher layer parameter, a hopping interval for the frequency hopping is the same as the length of the time domain window.
