Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems lack a mechanism to effectively signal metrics associated with antenna modules in user equipment (UE), which hinders network optimization and resource allocation, leading to potential interference and reduced performance due to varying antenna configurations and power management.
Innovation Solution
The implementation of a method where UE determines and transmits metrics associated with its antenna modules, such as the number, placement, type, and power consumption, to the base station, enabling the base station to perform network optimizations, resource allocation, and power management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If antenna module metrics are not signaled to the base station, then the system overhead is reduced, but network optimization and resource allocation performance deteriorate
Solution Approach 1:
The patent extracts only the essential antenna module metrics (such as number of antenna elements, antenna configuration type, and power management capabilities) from the complete UE antenna system and signals only these specific parameters to the base station. This selective extraction approach provides sufficient information for network optimization while minimizing signaling overhead compared to transmitting complete antenna system data.
Solution Approach 2:
The patent applies local quality by tailoring the metrics signaling to the specific needs of different antenna module configurations. Different UE devices with different antenna capabilities signal different sets of metrics appropriate to their local characteristics, allowing the base station to optimize resource allocation and interference management for each device's specific antenna configuration without requiring all devices to signal identical comprehensive data.
2Productivity
If detailed antenna module metrics are signaled, then network optimization and resource allocation improve, but system overhead increases
Solution Approach 1:
The patent extracts and signals only the most critical antenna module metrics that directly impact network optimization decisions, such as antenna configuration type, number of antenna elements, and power management capabilities. By filtering out less critical details, the system achieves effective network optimization while minimizing the energy consumed for metric determination and signaling.
Solution Approach 2:
The patent implements partial action by signaling a subset of potentially available antenna metrics - specifically those that are most valuable for base station decisions regarding resource allocation and interference management. This partial signaling approach provides sufficient information for effective network optimization without the excessive energy cost of determining and transmitting complete antenna system characterization data.
3Reliability
If antenna module metrics feedback mechanism is implemented, then interference mitigation and resource allocation accuracy improve, but device complexity increases
Solution Approach 1:
The patent simplifies the UE processing complexity by extracting and signaling only a limited set of predefined antenna module metrics that are directly relevant for interference mitigation and resource allocation. The base station receives these extracted metrics and uses them to make optimized decisions, achieving improved communication reliability without requiring complex UE-side processing for metric generation or interpretation.
Solution Approach 2:
The patent segments the antenna module characterization into distinct, manageable metric categories (such as antenna configuration, number of elements, power management capabilities) that can be independently determined and signaled. This segmentation reduces the overall complexity by breaking down the complex task of antenna characterization into simpler, modular components that are easier to process and transmit.

AI summary
Systems, methods, and devices for wireless communication that support mechanisms for signaling metrics associated with antenna modules of a UE in a wireless communication system. A user equipment (UE) determines one or more metrics associated with at least one antenna module of the UE. The UE transmits a message including the one or more metrics associated with at least one antenna module of the UE (e.g., to a base station or to another sidelink UE). In certain aspects, the message including the one or more metrics is transmitted to the base station during an initial establishment of a communication session between the UE and the base station. In some aspects, the UE transmits the message including the one or more metrics as a broadcast message, in a radio resource control (RRC) message, and/or in a medium access control (MAC)-control element (CE) message.
