Reporting Achievable Power Per Component Carrier With Multiple Sources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile and wireless telecommunication systems, such as 5G NR, face challenges in efficiently reporting and configuring achievable power per component carrier with multiple power sources, leading to limitations in power aggregation and resource scheduling.
Innovation Solution
The implementation of an apparatus and method that allow user equipment (UE) to report its band combination capabilities, including indication of component carrier groups and their associated power sources, enabling the network to configure power sources independently and optimize resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If user equipment reports band combination capabilities with multiple power sources, then power aggregation and resource scheduling efficiency is improved, but device complexity and signaling overhead increase
Solution Approach 1:
The patent segments the band combination capability reporting into distinct components: component carrier groups are formed by grouping component carriers that share the same power source, and separate reporting structures are created for different power source configurations. This segmentation allows the network to process power capability information in manageable units rather than as a single complex report.
Solution Approach 2:
The patent introduces a new dimension to capability reporting by adding power source identification and power capability parameters to the existing band combination framework. Instead of reporting only frequency band combinations, the system now reports power source associations and achievable power levels per component carrier group, transforming the reporting structure from two-dimensional (band-frequency) to three-dimensional (band-power-source).
2Power
If the network configures power sources independently per component carrier group, then power aggregation efficiency is improved, but configuration complexity and processing overhead increase
Solution Approach 1:
The patent divides the component carriers into distinct groups based on their power source associations. Each component carrier group is configured independently with its own power source parameters, allowing the network to optimize power allocation for each group separately rather than managing all component carriers as a single entity.
Solution Approach 2:
The patent implements preliminary grouping of component carriers by power source before configuration. By pre-organizing component carriers into groups that share the same power source, the network reduces the complexity of power configuration operations and enables more efficient power aggregation without requiring complex real-time calculations.

AI summary
Systems, methods, apparatuses, and computer program products for reporting of achievable power per component carrier with multiple power sources and configuration based on such reporting are provided. For example, a method can include receiving a request to report user equipment band combination capabilities. The method can also include reporting a capability of a user equipment to a network. The capability can include indication of one or more component carrier groups per band combination or per band. The one or more component carrier groups can contain indication of one or more power sources for the component carrier group.
