Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radio communication systems, particularly in future 5G and beyond generations, face challenges in effectively transmitting data over multiple slots using multi-TRP configurations, leading to potential degradation in communication throughput and quality unless a clear method is defined.
Innovation Solution
A terminal and radio communication method that includes a receiving section for parameters from multiple TRPs and a control section to manage the transmission of a transport block over multiple slots, applying appropriate parameters to each slot, ensuring efficient data transmission in multi-TRP configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multi-TRP configuration is implemented for data transmission over multiple slots, then communication throughput and quality can be enhanced, but the system complexity and parameter management difficulty increase
Solution Approach 1:
The patent segments the parameter application process by associating different parameters with different TRPs and applying them to different slots. Each TRP has its own set of parameters (first parameter for first TRP, second parameter for second TRP) that are applied to specific slots in the transmission sequence, enabling independent optimization of each transmission path while maintaining overall system management.
2Reliability
If multiple parameters are applied to multiple slots in multi-TRP mode, then transmission quality improves, but the control and scheduling complexity increases
Solution Approach 1:
The patent applies local quality by assigning specific parameters to specific TRPs and slots. The first parameter is applied to the first TRP for specific slots, and the second parameter is applied to the second TRP for specific slots. This localized parameter application allows optimization of transmission quality for each TRP-slot combination while maintaining clear control boundaries.
3Quantity of substance
If data is transmitted over multiple slots with multi-TRP, then communication capacity increases, but the difficulty of detecting and measuring transmission parameters increases
Solution Approach 1:
The patent segments the transmission process into distinct time slots with associated TRPs and parameters. By dividing the transmission into discrete units (first slot with first parameter, second slot with second parameter), the system makes it easier to detect and measure parameters for each segment rather than dealing with a complex integrated transmission across multiple TRPs and slots.

AI summary
A terminal according to one aspect of the present disclosure includes: a receiving section that receives a first parameter for transmission to a first transmission/reception point (TRP) and a second parameter for transmission to a second TRP; and a control section that controls transmission of one transport block over N slots and applies N parameters to the N respective slots, the N parameters including at least one of the first parameter and the second parameter, N being an integer equal to or greater than two. According to one aspect of the present disclosure, it is possible to appropriately carry out transmission of data over a plurality of slots in a case where multi-TRP is configured/indicated.
