Multi-Carrier Beam Update Signaling for Lower Indication Delay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional beam management in high-frequency communication systems incurs significant signaling overheads and delays due to the need for individual beam updates across multiple component carriers, as changes in one carrier require signaling on all carriers.
Innovation Solution
A method for updating beam information across multiple component carriers by associating them with a single beam configuration, allowing a single piece of signaling to update beam information for all carriers, reducing redundant configurations and signaling overheads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beam update information is sent on all component carriers individually, then beam information can be updated accurately, but signaling overheads increase significantly
Solution Approach 1:
The patent merges beam update information for multiple component carriers into a single signaling message. Instead of sending separate beam update indications on each component carrier, the network device sends one unified beam update indication that simultaneously updates beam information across multiple component carriers, thereby reducing signaling overhead while maintaining update accuracy.
Solution Approach 2:
The beam update indication is designed to serve multiple component carriers universally. A single beam update indication message can update beam information for the first component carrier and one or more second component carriers, making the signaling mechanism multi-functional and applicable across different carriers without requiring carrier-specific signaling.
2Adaptability or versatility
If beam update information is sent on all component carriers individually, then each carrier can be managed independently, but delay of beam indication increases
Solution Approach 1:
The patent combines beam update operations for multiple component carriers into a single simultaneous update action. By merging the update process, the system achieves faster beam indication since the update happens in one operation rather than sequentially across multiple carriers, thereby reducing the overall delay while still allowing independent management through the unified indication.
3Stability of the object's composition
If same signaling is sent on all component carriers to notify beam change, then beam consistency is maintained, but resource consumption increases
Solution Approach 1:
The patent merges multiple identical signaling transmissions into a single beam update indication. Instead of consuming resources to send the same beam update signaling on each component carrier separately, the system sends one unified indication that achieves the same beam consistency result across all carriers, thereby significantly reducing resource consumption and energy loss.

AI summary
This application provides methods and apparatuses for updating beam information. One method includes: receiving beam update information of a first component carrier (CC), and updating, based on the beam update information of the first CC, beam information of the first CC and beam information of one or more second CCs associated with the first CC.
