Wireless Data Channel Frequency Resource Allocation for Multi-TRP Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently managing bandwidth resources for multi-transmission and reception points (TRPs), leading to suboptimal data transmission and reception due to overlapping frequency resource regions.
Innovation Solution
A method for configuring frequency resource regions for data channels in a wireless communication system using precoding information, where a user equipment (UE) receives configuration information and downlink control information to allocate non-overlapping frequency resource regions for multiple data channels, allowing for efficient MIMO-based data transmission and reception.

Engineering Contradiction Analysis
1Productivity
If overlapping frequency resource regions are used for multiple TRPs, then resource utilization is improved, but interference between TRPs increases and transmission reliability deteriorates
Solution Approach 1:
The frequency resource region is segmented into multiple non-overlapping sub-regions, with each sub-region assigned to a specific TRP. This segmentation eliminates interference between TRPs while maintaining high resource utilization by fully allocating the available frequency spectrum across different TRPs without overlap.
2Reliability
If non-overlapping frequency resource regions are used for multiple TRPs, then interference between TRPs is reduced and transmission reliability is improved, but resource utilization efficiency deteriorates
Solution Approach 1:
The system dynamically changes the allocation parameters of frequency resources by adjusting which non-overlapping sub-regions are assigned to which TRPs based on channel conditions, traffic demands, and QoS requirements. This allows the system to maintain non-overlapping allocation for reliability while optimizing resource utilization efficiency through adaptive parameter adjustment.
3Productivity
If multiple data channels are configured for multiple TRPs, then data transmission capacity is improved, but frequency resource management complexity increases
Solution Approach 1:
The patent introduces a spatial dimension to frequency resource management by associating specific frequency sub-regions with specific TRPs in the spatial domain. This multidimensional approach (frequency + space) allows multiple data channels to be configured for multiple TRPs while simplifying management through clear spatial-frequency mapping relationships, where each TRP has dedicated frequency resources.
