Multi-Panel Uplink Transmission via CORESET Pool Differentiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently supporting simultaneous uplink transmission using multiple panels, particularly in 5G and beyond systems, where different services like eMBB, URLLC, and mMTC require distinct transmission techniques and parameters, leading to complexity and potential interference.
Innovation Solution
The method involves a UE and base station configuration where multiple physical uplink shared channels (PUSCH) can be transmitted simultaneously using overlapping resources, with the UE identifying and utilizing different CORESET pool identifiers to manage these transmissions effectively, allowing for coordinated resource allocation and interference mitigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple PUSCH transmissions are performed simultaneously using multiple panels, then data transmission rate and system productivity are improved, but device complexity and signal interference increase
Solution Approach 1:
The patent segments the uplink transmission by associating each PUSCH with a distinct CORESET pool identifier (0 or 1). This segmentation allows the UE to manage multiple simultaneous transmissions by identifying them through different CORESET pools, thereby reducing transmission management complexity while maintaining high data transmission rates through multi-panel simultaneous operation
Solution Approach 2:
The patent introduces a new dimension for transmission management by using CORESET pool identifiers as an additional classification parameter. This dimensional approach allows the system to distinguish and manage multiple PUSCH transmissions not just by time or frequency resources, but by their associated CORESET pool identity, thereby simplifying the management of complex multi-panel transmissions
2Productivity
If multiple PUSCH transmissions are performed simultaneously using multiple panels, then system productivity is improved, but signal interference increases
Solution Approach 1:
The patent segments simultaneous PUSCH transmissions into distinct groups based on their CORESET pool identifiers. By associating each transmission with a specific CORESET pool (0 or 1), the system can manage and separate interfering signals, allowing high system throughput through simultaneous transmissions while mitigating interference through identifier-based differentiation
Solution Approach 2:
The CORESET pool identifier acts as an intermediary parameter that mediates between multiple simultaneous PUSCH transmissions. This intermediary allows the system to coordinate and manage overlapping transmissions from different panels, enabling high system throughput while reducing harmful interference through structured identification and management
3Adaptability or versatility
If multiple CORESET pools are configured for different services, then adaptability and versatility are improved, but device complexity increases
Solution Approach 1:
The patent implements a universal CORESET pool identifier system that can be applied across different service types (eMBB, URLLC, mMTC). Each service can be associated with a specific CORESET pool, creating a multi-functional framework that enhances adaptability and versatility while maintaining relatively simple configuration through the standardized two-pool structure

AI summary
The disclosure relates to a fifth generation (5G) or sixth generation (6G) communication system for supporting higher data transfer rates. A method performed by a user equipment (UE) in a wireless communication system, the method comprising: receiving configuration information on a resource for transmitting a first physical uplink shared channel (PUSCH) based on a configured grant, the first PUSCH being associated with a first control resource set (CORESET) pool identifier; receiving downlink control information (DCI) including information on a resource for transmitting a second PUSCH based on a dynamic grant (DG), the second PUSCH being associated with a second CORESET pool identifier, wherein the resource for transmitting the first PUSCH overlaps with all or part of the resource for transmitting the second PUSCH in a time domain; identifying whether a value of the first CORESET pool identifier is different from a value of the second CORESET pool identifier; and in case that the value of the first CORESET pool identifier is identified to be different from the value of the second CORESET pool identifier, transmitting the first PUSCH and the second PUSCH.
