Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack an efficient solution for data transmission between multiple TRPs and a terminal, particularly in multi-TRP transmission scenarios, where resource collisions and interference are significant due to differing transmission parameters.
Innovation Solution
A configuration information transmission method and device that transmit multiple sets of data channel, control channel resource, and measurement reference signal configuration information for a single frequency domain bandwidth, along with determining correspondence between control channel resources and transmission parameter sets, and determining timing advance information for accurate signal transmission.

Engineering Contradiction Analysis
1Productivity
If multiple TRPs transmit data using independent transmission parameters, then data transmission capability is improved, but resource collisions and interference increase
Solution Approach 1:
The patent segments the transmission system into multiple independent TRP units, each with its own transmission parameters. This allows parallel data transmission from multiple TRPs to a terminal, improving overall data transmission capability while maintaining independent control over each TRP's resources to avoid collisions and interference.
2Adaptability or versatility
If multiple sets of configuration information are configured for multiple TRPs, then transmission flexibility is improved, but signaling complexity increases
Solution Approach 1:
The patent implements a unified configuration management mechanism where a single configuration information structure can serve multiple TRPs. The configuration information includes parameters that can be universally applied across multiple TRPs while allowing specific TRP-specific adjustments, thereby providing transmission flexibility without proportionally increasing signaling complexity.

AI summary
Provided are configuration information transmission method and device. The method includes: transmitting configuration information, where the configuration information includes at least one of the following: configuring N sets of data channel configuration information for one frequency domain bandwidth, configuring M sets of control channel resource configuration information for one frequency domain bandwidth, or configuring C sets of measurement reference signal configuration information for one frequency domain bandwidth, where N, M, and C are integers greater than or equal to 1. The above solution resolves the issue of the lack of data transmission between multiple TRPs and a terminal in the related art. Multiple sets of configuration information are configured for one frequency domain bandwidth, such that different configuration information can be used in multi-TRP transmission, thereby realizing data transmission between multiple TRPs and a terminal.
