Dynamic L1 Resource Allocation in Wireless BBU Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing indoor distribution systems for mobile communication waste L1 processing resources due to fixed allocation based on physical cells, leading to underutilization when data processing demands are low.
Innovation Solution
A data processing method where a BBU dynamically configures L1 processing resources based on the total amount of user data in a logical cell, decoupling them from physical cells, and adjusts pRRU usage based on signal quality to optimize resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If L1 processing resources are fixedly configured based on physical cells, then each physical cell has dedicated processing resources, but L1 processing resources are wasted when data processing demands are low
Solution Approach 1:
The patent implements dynamic L1 processing resource allocation by allowing L1 processing resources to be flexibly assigned across multiple physical cells based on real-time data processing demands. Instead of fixed one-to-one mapping, the system dynamically adjusts which L1 processing resources serve which physical cells, enabling resources to be activated or deactivated according to actual traffic needs and thereby reducing resource waste while maintaining reliable processing capability.
Solution Approach 2:
The patent makes L1 processing resources universal by enabling a single L1 processing resource to serve multiple physical cells rather than being dedicated to one cell. This multi-functional approach allows the same processing resource to be shared across different physical cells depending on demand, improving resource utilization efficiency while maintaining the ability to provide dedicated processing when needed.
2Productivity
If more L1 processing resources are configured to handle larger quantities of physical cells, then processing capacity increases, but resource utilization decreases when some cells have low data traffic
Solution Approach 1:
The system dynamically adjusts L1 processing resource allocation based on real-time data processing demands across multiple physical cells. When traffic demand is low in certain cells, their dedicated L1 processing resources can be deactivated or reassigned to other cells with higher demand, thereby maintaining adequate processing capacity while improving overall resource utilization efficiency and reducing energy consumption from idle resources.
Solution Approach 2:
The patent merges the processing capabilities across multiple physical cells by allowing L1 processing resources to be shared and consolidated. Instead of maintaining separate dedicated resources for each cell, the system combines processing capabilities into a pool that can be dynamically allocated, enabling efficient handling of varying traffic loads across cells while improving overall resource utilization.

AI summary
Disclosed are a data processing method and apparatus, which relate to the field of wireless communication technologies. In one example, a BBU determines an amount of user data in a logical cell covered by the BBU, where the amount of the user data in the logical cell covered by the BBU is a total amount of to-be-processed data in the logical cell covered by the BBU; and the BBU configures, based on the amount of the user data in the logical cell covered by the BBU, M L1 processing resources whose data processing capacity meets the amount of the user data in the logical cell covered by the BBU, and processes the to-be-processed data by using the M L1 processing resources.
