Radio Unit Batch Numbering for Carrier Reconfiguration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face performance issues due to unpredictable carrier configurations and interference, leading to increased latency and resource inefficiencies when multiple configuration changes are made, often requiring temporary disabling of carriers or reassignment to other base stations.
Innovation Solution
Implementing batch numbering for configuration commands allows radio units to store and execute multiple configuration changes at a common time, avoiding intermediate states and reducing the need for temporary carrier disabling or reassignment, thereby enhancing resource availability and performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple configuration commands are executed sequentially to change carrier configuration, then the carrier can be reconfigured from first configuration to second configuration, but unpredictable intermediate states occur leading to performance degradation
Solution Approach 1:
The system stores multiple configuration commands in a buffer before execution, preparing them in advance. This preliminary storage allows the system to execute all configuration changes atomically at a trigger event, preventing unpredictable intermediate states that would occur with sequential execution.
Solution Approach 2:
Multiple configuration commands are merged into a single batch operation. Instead of executing commands one by one, the system combines them into a unified reconfiguration event that transitions the carrier directly from the first configuration to the second configuration, eliminating intermediate states.
2Reliability
If the carrier is temporarily disabled during configuration changes, then configuration reconfiguration can be performed without interference, but wireless communication resource availability decreases and latency increases
Solution Approach 1:
The carrier remains enabled and continues to serve wireless communications throughout the configuration reconfiguration process. By using batch numbering and trigger-based execution, the system maintains continuous carrier operation without temporary disabling, thus avoiding service disruption and reducing latency.
3Reliability
If the carrier is reassigned to another base station during configuration changes, then configuration can be modified without service disruption, but processing resources and wireless resources are consumed for scheduling and implementation
Solution Approach 1:
The base station performs configuration reconfiguration itself without requiring carrier reassignment to another base station. The system uses internal batch buffering and trigger mechanisms to handle configuration changes autonomously, eliminating the need for external scheduling and reducing processing resource consumption.
4Adaptability or versatility
If multiple configuration commands are executed in sequence, then detailed configuration changes can be applied, but resource utilization efficiency decreases due to repeated processing
Solution Approach 1:
Multiple configuration commands are merged into a single batch operation that executes all changes simultaneously. This approach maintains the flexibility to apply detailed configuration changes while improving resource utilization efficiency by eliminating repeated processing overhead associated with sequential execution.

AI summary
An apparatus for wireless communication by a network entity includes a memory and one or more processors coupled to the memory. The one or more processors are configured to receive one or more configuration commands associated with a carrier having a first configuration. The one or more configuration commands each indicate a batch number. The one or more processors are further configured to store the one or more configuration commands and, based on detection of a trigger event, to perform a reconfiguration of the carrier from the first configuration to a second configuration that is based on the one or more configuration commands.
