Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently configuring and managing slot-level operations in open radio access networks (O-RAN), particularly in managing slot-level configurations and beamforming for multiple endpoints, which can lead to inefficiencies and interference.
Innovation Solution
Implementing a control plane message with a common section header and section type commands for slot-level configuration, enabling radio frequency configuration and time domain beamforming for groups of endpoints, thereby optimizing slot-level operations.

1Productivity
If traditional control messages are used for slot-level configuration in O-RAN, then compatibility with existing systems is maintained, but configuration efficiency and coordination for multiple endpoints deteriorates
Solution Approach 1:
The control message is segmented into a common section header (containing common configuration information applicable to multiple endpoints) and multiple section type commands (each targeting specific endpoints or endpoint groups). This segmentation allows efficient distribution of configuration data while maintaining a structured, manageable message format that doesn't overwhelm the system with complexity.
Solution Approach 2:
The message structure introduces a new dimensional organization by separating common configurations (applicable to all endpoints) from specific configurations (applicable to individual endpoints or groups). This dimensional separation enables the system to handle multiple endpoints efficiently without linearly increasing message complexity, as common settings are defined once and reused across multiple section type commands.
2Ease of operation
If separate control messages are sent to each endpoint for slot-level configuration, then individual endpoint control is achieved, but signaling overhead and network resource consumption increases
Solution Approach 1:
Multiple configuration operations for multiple endpoints are merged into a single control message. The common section header contains configuration information that applies to multiple endpoints, eliminating the need to send separate messages to each endpoint. This merging significantly reduces signaling overhead and network resource consumption while still allowing individual endpoint control through the section type commands.
Solution Approach 2:
The common section header serves a universal function by containing configuration information that can be applied to multiple endpoints simultaneously. This multi-functional design allows a single message to perform what would traditionally require multiple separate messages, reducing network resource consumption while maintaining the ability to control individual endpoints through the associated section type commands.
3Manufacturing precision
If detailed slot-level configuration is provided for each endpoint, then configuration precision is improved, but message size and processing time increases
Solution Approach 1:
Common configuration information is prepared in advance in the common section header, which applies to multiple endpoints. This preliminary preparation eliminates the need to repeat the same configuration data for each endpoint, significantly reducing message size and processing time while maintaining precise control over slot-level operations for each endpoint through the section type commands.
Solution Approach 2:
The message structure applies local quality by providing detailed, precise configuration information only where needed. The common section header provides general configuration applicable to multiple endpoints, while section type commands provide endpoint-specific details. This approach maintains configuration precision for each endpoint without unnecessarily increasing overall message size or processing time.
4Adaptability or versatility
If slot-level configuration is implemented without a standardized message structure, then implementation flexibility is maintained, but system reliability and interoperability deteriorates
Solution Approach 1:
The message structure uses parameterized section type commands that can be configured to match different endpoint requirements. The common section header and section type commands work together with configurable parameters to provide standardized yet flexible configuration. This parameterized approach ensures reliable interoperability across different implementations while maintaining the adaptability needed for various endpoint configurations.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a radio unit (RU) may receive, from a distributed unit (DU), a control plane message associated with a section type that is dedicated for slot level configuration information. The control plane message may include a common section header that identifies a group of one or more endpoints, and one or more section type commands that include information associated with a slot level common configuration for the group of one or more endpoints. The RU may perform at least one of radio frequency configuration or time domain beamforming for the group of one or more endpoints based at least in part on the information included in the one or more section type commands. Numerous other aspects are described.
