Solution Overview
Problem
The complexity of system design and scheduling flexibility are compromised in scenarios where PUSCH and PUCCH overlap, necessitating a solution to enhance system optimization.
Innovation Solution
A method involving the use of coresetPoolIndex values to differentiate or maintain consistency based on whether the target physical uplink channel is a PUCCH or PUSCH, thereby reducing system design complexity and improving scheduling flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the system allows flexible scheduling of overlapping PUSCH and PUCCH channels, then scheduling flexibility is improved, but system design complexity increases
Solution Approach 1:
The patent changes the parameter coresetPoolIndex to differentiate between PUCCH and PUSCH handling. When coresetPoolIndex values differ, the system allows PUSCH transmission to overlap with PUCCH, providing scheduling flexibility. When coresetPoolIndex values are the same, the system prohibits overlap, reducing design complexity. This parameter-based approach resolves the contradiction by dynamically adjusting system behavior based on channel type.
2Device complexity
If the system prohibits PUSCH transmission when overlapping with PUCCH, then system design complexity is reduced, but uplink transmission efficiency deteriorates
Solution Approach 1:
The patent applies local quality by treating PUCCH and PUSCH differently based on their coresetPoolIndex values. Instead of a blanket prohibition, the system allows PUSCH transmission when coresetPoolIndex differs from the PUCCH's index, while maintaining prohibition when indices are the same. This localized differentiation reduces unnecessary restrictions on uplink transmission efficiency while keeping system design manageable.
3Adaptability or versatility
If the system allows PUSCH transmission when coresetPoolIndex values differ, then scheduling flexibility is improved, but the risk of interference between channels increases
Solution Approach 1:
The coresetPoolIndex acts as an intermediary parameter that mediates between PUCCH and PUSCH transmissions. By using this index as a differentiator, the system can safely allow overlapping transmissions when indices differ, implying that the intermediary parameter ensures proper resource separation and prevents harmful interference while maintaining scheduling flexibility.
