Multi-PUSCH Configured Grant FDRA Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face limitations in communication capacity, speed, flexibility, and efficiency, particularly in the configuration and transmission of multiple Physical Uplink Shared Channels (PUSCHs) with configured grants.
Innovation Solution
The system enhances multi-PUSCH configured grant transmission by allowing the user equipment (UE) to receive a list of frequency domain resource allocations (FDRAs) and determine an FDRA index for each configured grant PUSCH transmission, with the UE transmitting a frequency domain resource allocation-uplink control information (FDRA-UCI) to indicate the used FDRA.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple PUSCHs with configured grants are transmitted using fixed resource allocations, then device complexity is reduced and ease of operation is improved, but communication flexibility and resource utilization efficiency deteriorate
Solution Approach 1:
The patent applies dynamics by enabling the UE to dynamically select frequency domain resource allocations from a pre-configured list of FDRAs for each PUSCH transmission occasion. This allows the system to maintain the simplicity of configured grant transmission while introducing flexibility through dynamic resource selection based on current traffic conditions and channel state, directly resolving the contradiction between ease of operation and communication flexibility.
2Device complexity
If fixed frequency domain resource allocations are used for configured grant PUSCH transmissions, then device complexity is reduced, but resource utilization efficiency and adaptability to traffic conditions deteriorate
Solution Approach 1:
The patent applies preliminary action by pre-configuring a list of frequency domain resource allocations (FDRAs) through higher layer signaling before transmission occurs. The UE then selects from this pre-prepared list based on current conditions, avoiding complex real-time resource allocation calculations while maintaining high resource utilization efficiency. This resolves the contradiction by performing complex work in advance rather than during transmission.
3Adaptability or versatility
If dynamic resource selection is implemented for each PUSCH transmission occasion, then communication flexibility and resource utilization are improved, but device complexity and signaling overhead increase
Solution Approach 1:
The patent applies segmentation by dividing the frequency domain resources into multiple pre-defined allocation options (list of FDRAs) that are configured separately through higher layer signaling. The UE simply selects from this segmented list based on transmission needs, avoiding the complexity of continuous resource calculation while maintaining flexibility. This resolves the contradiction by segmenting the resource space into manageable discrete options.

AI summary
A user equipment (UE) is described. The UE includes receiving circuitry configured to receive a list of frequency domain resource allocations (FDRAs) for a configured grant (CG) with multiple physical uplink shared channel (PUSCH) transmission occasions (TOs). The UE also includes transmitting circuitry configured to determine an FDRA index for a CG PUSCH transmission, and transmit a frequency domain resource allocation-uplink control information (FDRA-UCI) to indicate the FDRA used in the CG PUSCH transmission.
