5G CU-DU Parallel Information Exchange to Reduce Interaction Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The interaction time between multiple distributed unit (DU) entities and a centralized unit (CU) entity in 5G systems is excessively long, leading to low efficiency in achieving interaction scenarios.
Innovation Solution
Implementing an interaction method where the CU entity receives and sends information in parallel to and from multiple DU entities, including determining and integrating information before sending, and receiving responses in parallel, to streamline the interaction process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If multiple DU entities interact with the CU entity sequentially, then the interaction process is simple to manage, but the total interaction time becomes excessively long
Solution Approach 1:
The patent segments the interaction process by introducing indication information that identifies which DU entities should interact with the CU entity. This segmentation allows the system to selectively engage only the necessary DU entities (first DU entities) while excluding others (second DU entities), thereby reducing the total interaction time without requiring all DU entities to participate in every interaction scenario.
Solution Approach 2:
The patent implements dynamic interaction by allowing the set of participating DU entities to change based on the interaction scenario. The indication information dynamically determines which DU entities are involved in each interaction, enabling the system to adapt the interaction process to specific scenarios (such as handover or initial access) rather than following a fixed sequential pattern for all cases.
2Reliability
If the CU entity interacts with all DU entities, then comprehensive coverage is achieved, but the interaction time increases significantly
Solution Approach 1:
The patent segments the DU entities into two groups: first DU entities that need to interact with the CU entity based on the indication information, and second DU entities that do not participate in the current interaction. This segmentation ensures that the CU entity interacts only with the necessary DU entities, maintaining reliable coverage for the specific interaction scenario while avoiding unnecessary interactions that would increase time consumption.
Solution Approach 2:
The patent applies partial action by having the CU entity interact only with the subset of DU entities that are relevant to the current scenario, rather than interacting with all DU entities. The indication information enables the CU entity to perform partial interactions (with first DU entities) that are sufficient to achieve the interaction objective without the excessive action of involving all DU entities.

AI summary
The present disclosure provides an interaction method and related device. The method includes: receiving first information sent in parallel by a plurality of first distributed unit entities (DUs) accessed by user equipment (UE); and sending, to each first DU, second information corresponding to the first DUs in parallel.
