Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is currently no solution for selecting a baseband processing combination (BPC) capability used by user equipment (UE) in a serving base station with a centralized unit (CU) and distributed unit (DU) architecture.
Innovation Solution
A method and device for configuring BPC capability, where a second network element of a base station selects a BPC for a UE during the access process, utilizing a configuration module to determine the appropriate BPC based on the current radio resource situation and other factors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the BPC capability selection is performed in a separated base station architecture with CU and DU, then the system can support distributed deployment and improved scalability, but there is no existing solution for selecting the appropriate BPC capability for UE
Solution Approach 1:
The patent introduces an intermediary mechanism where the network element responsible for scheduling UE communications acts as a mediator to select the BPC capability. This mediator coordinates between the separated CU and DU components, utilizing available information about radio resources and network environment to make an informed BPC selection, thus resolving the contradiction between architectural separation and reliable capability selection.
2Device complexity
If the BPC selection is made without knowledge of underlying radio resources, then the system architecture remains simple and modular, but incorrect BPC selection may occur leading to performance degradation
Solution Approach 1:
The patent applies preliminary action by having the network element gather necessary information about radio resources and network environment conditions before making the BPC capability selection. This advance preparation ensures that when the BPC selection is made, it is based on accurate and relevant information, thereby improving configuration accuracy without significantly increasing overall system complexity.
3Productivity
If the BPC capability is selected to maximize UE performance, then the system can achieve optimal communication efficiency, but the selected BPC may exceed the UE's actual capability range causing system failures
Solution Approach 1:
The patent implements a feedback mechanism where the network element that selects the BPC capability is also responsible for monitoring whether the selected capability is appropriate for the UE's actual performance. This feedback loop allows the system to adjust and refine BPC selections over time, ensuring that high communication efficiency is achieved while maintaining compliance with UE capability limits and preventing system failures.

AI summary
Disclosed are a baseband processing combination (BPC) capability configuration method and device, a base station and a computer storage medium. The base station includes a network element and a second network element connected to the first network element. The first network element and the second network element are separately deployed, the first network element is responsible for radio resource management, and the second network element is responsible for underlying radio transmission management. In the process of a UE accessing the second network element of the base station, the second network element of the base station selects a BPC for the UE, and the base station can then schedule the UE according to the BPC selected by the second network element for the UE and perform necessary radio resource configuration.
