Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beam management technologies in cellular networks struggle to efficiently identify and utilize secondary usable-angular power areas (SU-APAs) by User Equipments (UEs), leading to suboptimal power alignment and potential losses between UEs and access nodes.
Innovation Solution
The implementation of a User Equipment (UE) that reports Primary-Angular Power Areas (P-APAs) and indicates the availability of Secondary Useable-Angular Power Areas (SU-APAs) to a node apparatus, allowing for dynamic adjustment of transmission configurations and threshold settings based on received power levels.

Engineering Contradiction Analysis
1Use of energy by moving object
If beam management uses only Primary-Angular Power Area (P-APA) for power alignment, then the system complexity is low, but the power efficiency and communication performance are suboptimal due to inability to utilize secondary usable areas
Solution Approach 1:
The patent segments the angular power areas into Primary-Angular Power Area (P-APA) and Secondary Useable-Angular Power Areas (SU-APAs). This segmentation allows the system to identify and utilize multiple distinct angular regions for beam transmission, improving power efficiency by selecting the most suitable APA while maintaining manageable system complexity through structured classification.
Solution Approach 2:
The patent implements dynamic selection and reporting of APAs based on received power levels. The UE dynamically identifies P-APA and SU-APAs, reports them to the gNB, and enables the gNB to dynamically adjust transmission configurations. This dynamic approach optimizes power efficiency while the standardized reporting mechanisms keep system complexity controlled.
2Measurement precision
If the UE reports multiple Angular Power Areas (P-APA and SU-APAs), then the beam alignment accuracy is improved, but the signaling overhead and measurement complexity increase
Solution Approach 1:
The patent applies partial action by having the UE report only the most relevant APAs (P-APA and up to a limited number of SU-APAs) rather than all possible angular areas. The gNB requests APA information only when needed for beam management decisions. This approach maintains high beam alignment accuracy while minimizing signaling overhead by avoiding unnecessary reporting of all angular regions.
3Productivity
If the system dynamically adjusts transmission configurations based on SU-APA availability, then the communication performance is optimized, but the processing complexity and computational requirements increase
Solution Approach 1:
The patent implements preliminary action by having the UE pre-identify and report P-APA and SU-APAs before actual data transmission. The gNB uses this pre-reported information to select optimal transmission configurations. This preliminary identification and reporting simplifies the real-time processing complexity during actual communication while still enabling optimized performance through advance preparation of APA information.

AI summary
Examples of the disclosure beam management within networks comprising User Equipments (UEs) that can be configured to receive power from different beams. The UEs can be configured to report at least one Primary-Angular Power Area (P-APA) and an indication of the availability of at least one Secondary Useable-Angular Power Area (SU-APA) for the UE. An Angular Power Area comprises a range of angular directions from which the UE is receiving power from a node apparatus and the SU-APA comprises a different area to the P-APA.
