Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless network technologies, such as those defined in 3GPP TSs, do not support simultaneous multi-panel transmission for spatial division multiplexing (SDM) or frequency division multiplexing (FDM) in New Radio (NR) Release 17, limiting the capability for simultaneous PUSCH transmissions across multiple antenna panels.
Innovation Solution
The implementation of a configured grant (CG) and dynamic grant (DG) simultaneous multi-panel transmission scheme, where the user equipment (UE) can transmit PUSCH signals across multiple panels using different transmission schemes like FDM-A, FDM-B, SDM, or SFN, with specific resource allocation and beam indication mechanisms, allowing for simultaneous CG+CG or CG+DG transmissions based on UE capability and priority.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If simultaneous multi-panel transmission is implemented, then uplink transmission capacity and reliability are improved, but system complexity and resource management difficulty increase
Solution Approach 1:
The patent segments the uplink transmission system into multiple independent panels, each capable of simultaneous transmission. This allows the system to increase overall capacity by dividing the transmission function across multiple panels while managing complexity through modular design, where each panel operates semi-independently with its own resource allocation.
Solution Approach 2:
The patent introduces spatial dimensionality by enabling transmissions from multiple panels simultaneously in different spatial directions. This transforms the traditional single-dimension time-frequency resource allocation into multi-dimensional resource management, allowing parallel transmissions that increase capacity while the standardized panel interface helps manage the resulting system complexity.
2Adaptability or versatility
If multiple transmission schemes (FDM, SDM) are supported simultaneously, then transmission flexibility and adaptability are improved, but resource allocation complexity increases
Solution Approach 1:
The patent implements a universal resource allocation framework that supports multiple transmission schemes (FDM, SDM, and hybrid schemes) through a common standardized interface. This multi-functional design allows the system to adapt to different channel conditions and traffic requirements while managing complexity through unified resource management procedures that work across all transmission modes.
Solution Approach 2:
The patent enables dynamic selection and switching between different transmission schemes based on real-time channel conditions, traffic requirements, and panel availability. This dynamic adaptability allows the system to optimize performance by selecting the most appropriate transmission mode while the standardized resource allocation framework helps manage the complexity of handling multiple schemes simultaneously.
3Reliability
If simultaneous CG+CG or CG+DG transmissions are enabled, then uplink reliability and throughput are improved, but scheduling and coordination difficulty increase
Solution Approach 1:
The patent employs preliminary resource allocation and panel assignment for configured grant (CG) transmissions, where resources are pre-configured and assigned to specific panels in advance. This preliminary action simplifies the scheduling of simultaneous CG+CG or CG+DG transmissions by establishing resource allocations before the actual transmission occurs, reducing the coordination complexity during real-time operation while maintaining high reliability through pre-planned resource distribution.
4Reliability
If multiple antenna panels are used for simultaneous transmission, then signal diversity and connection reliability are improved, but device hardware complexity increases
Solution Approach 1:
The patent segments the antenna system into multiple independent panels, each with its own transmit and receive capabilities. This segmentation provides signal diversity and improved connection reliability by allowing simultaneous transmissions from multiple spatially separated panels, while the modular panel design helps manage hardware complexity through standardized interfaces and independent panel operation.
