Terminal Rate Matching via Multi-Cell Reference Signal Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In future radio communication systems, particularly in inter-cell mobility and multi-TRP scenarios, the challenge lies in appropriately controlling rate matching based on CRS patterns of cells other than the serving cell, which can lead to reduced throughput and deteriorated communication quality if not properly managed.
Innovation Solution
A terminal is equipped with a receiving section to gather information on reference signal patterns from both the serving cell and other cells, and a control section that uses this information to manage the reception of downlink channels, enabling appropriate rate matching across multiple cells and transmission/reception points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rate matching is controlled based on CRS pattern information from the serving cell only, then the reception processing is simple, but the communication quality deteriorates in inter-cell mobility and multi-TRP scenarios
Solution Approach 1:
The patent segments the CRS pattern information into multiple separate configurations: first CRS pattern information for the serving cell and second CRS pattern information for non-serving cells. This segmentation allows the terminal to handle different cell types with their respective CRS patterns independently, improving communication quality in inter-cell mobility and multi-TRP scenarios while maintaining manageable processing complexity through structured organization.
Solution Approach 2:
The patent introduces additional parameters (second CRS pattern information) to the existing system. By changing the parameter set from single-cell CRS pattern to multi-cell CRS pattern information, the system adapts to inter-cell mobility and multi-TRP scenarios, enabling appropriate rate matching control across multiple cells and transmission points.
2Productivity
If rate matching is controlled based on CRS patterns of multiple cells, then the throughput and communication quality improve, but the reception processing complexity increases
Solution Approach 1:
The patent segments CRS pattern information by cell type (serving cell vs. non-serving cell), organizing multiple CRS patterns into structured groups. This segmentation enables the terminal to efficiently process multiple cell configurations without overwhelming complexity, as each segment can be handled with specific processing rules.
Solution Approach 2:
The patent performs preliminary configuration of CRS pattern information for multiple cells before actual data reception. By pre-configuring the first and second CRS pattern information, the terminal prepares rate matching parameters in advance, enabling efficient throughput performance during actual communication without real-time processing overhead.

AI summary
Reception processing can be appropriately performed in inter-cell mobility/inter-multi-TRP mobility. A terminal according to an aspect of the present disclosure includes: a receiving section that receives first information regarding a first reference signal pattern corresponding to a serving cell and second information regarding a second reference signal pattern corresponding to one or more other cells different from the serving cell; and a control section that controls reception of a DL channel on the basis of at least one of the first information and the second information.
