Beam Management Capability Reporting in Multi-Carrier Aggregation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in managing beams effectively due to limitations in reporting beam management capabilities, particularly in multi-carrier aggregation scenarios, where terminals may support both independent beam management (IBM) and common beam management (CBM), but existing signaling formats do not adequately reserve extension bits to configure these modes according to network scheduling requirements.
Innovation Solution
A method and apparatus for reporting beam management capability information, where a terminal and base station use specific signalings to indicate support for IBM and CBM modes, allowing the base station to select the appropriate beam management mode for flexible management, by using signalings like supportedBandCombinationList-v1630 and beamManagementType-r16 to convey the terminal's capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing signaling formats are used to report beam management capability information, then the terminal can indicate support for beam management modes, but the signaling formats do not adequately reserve extension bits to configure both IBM and CBM modes according to network scheduling requirements
Solution Approach 1:
The capability information is segmented into multiple independent indication fields: first indication information for IBM mode support and second indication information for CBM mode support. This segmentation allows each beam management mode to be indicated independently, enabling complete and flexible capability reporting without requiring extensive extension bits in the signaling format.
2Adaptability or versatility
If the terminal reports detailed beam management capability information for both IBM and CBM modes, then the base station can select appropriate modes for flexible management, but the signaling complexity increases
Solution Approach 1:
The patent applies partial action by introducing optional third indication information that specifies whether the first and second indication information indicate the same beam management mode or different modes. This optional element provides enhanced flexibility only when needed, rather than requiring a complex signaling format to handle all possible scenarios explicitly.
3Adaptability or versatility
If the signaling format reserves extension bits for future configurations, then more beam management modes can be supported, but the current signaling structure becomes less efficient
Solution Approach 1:
The first and second indication information fields are designed with universal applicability, where each field can independently indicate support for different beam management modes. The optional third indication information provides an additional layer of universality by enabling the representation of relationships between the first and second indications, making the signaling format adaptable to various configuration scenarios without requiring format changes.
