Simultaneous Beam Update Across Multiple Component Carriers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in beam management when performing carrier aggregation, as they often require individual beam updates for each component carrier, leading to latency and overhead, especially since not all user equipment (UEs) universally support simultaneous beam updates across multiple component carriers.
Innovation Solution
A method where a UE transmits its capability to support simultaneous beam updates across multiple component carriers to a base station, allowing the base station to send a beam update command that can be applied to multiple component carriers based on this capability, enabling efficient simultaneous updates of transmission configuration indicator (TCI) states and spatial relations across multiple carriers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual beam updates are performed for each component carrier, then compatibility with all UEs is maintained, but overhead and latency increase
Solution Approach 1:
The system dynamically adapts beam update behavior based on UE capability. UEs that support simultaneous beam updates receive single-command updates across multiple component carriers, while UEs that do not support this feature receive individual carrier updates. This dynamic adaptation resolves the contradiction by optimizing performance for capable UEs while maintaining compatibility for others.
Solution Approach 2:
The patent introduces a capability parameter that indicates whether a UE supports simultaneous beam updates across multiple component carriers. This parameter change enables the network to differentiate between UE types and apply appropriate beam update strategies, thereby reducing latency for capable UEs without compromising compatibility.
2Adaptability or versatility
If individual beam updates are performed for each component carrier, then UE capability requirements are simplified, but beam management overhead increases
Solution Approach 1:
The patent segments UEs into two groups based on their beam update capability: UEs that support simultaneous beam updates across multiple component carriers, and UEs that do not. This segmentation allows the network to apply optimized beam update procedures only to capable UEs, reducing overall overhead while maintaining broad compatibility.
Solution Approach 2:
The solution provides a universal beam update mechanism that works for all UEs through individual carrier updates, while simultaneously enabling an optimized multi-carrier update mode for capable UEs. This multi-functionality approach reduces overhead for advanced UEs without sacrificing compatibility with legacy devices.
3Productivity
If simultaneous beam updates across multiple component carriers are implemented, then communication efficiency improves, but device complexity increases
Solution Approach 1:
The system dynamically selects the beam update mode based on UE capability indication. Capable UEs receive simultaneous multi-carrier beam updates that improve efficiency, while other UEs receive traditional individual carrier updates. This dynamic selection allows efficiency improvements without forcing complexity on all devices.
Solution Approach 2:
The patent introduces a capability parameter that UEs can set to indicate support for simultaneous beam updates. This parameter change enables capable devices to utilize optimized procedures while maintaining backward compatibility, allowing productivity improvements without universally increasing device complexity.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, information indicating a capability of the UE to support a simultaneous beam update across multiple component carriers. The UE may receive, from the base station, a beam update command identifying a component carrier configured for the UE based at least in part on the capability of the UE to support the simultaneous beam update across multiple component carriers. The UE may apply the beam update command to one or more component carriers based at least in part on the component carrier identified in the beam update command. Numerous other aspects are provided.
