Dynamic Antenna Element Selection for Wireless Beam Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems lack dynamic beam selection capabilities that adapt to varying application contexts, leading to inefficient power usage and network resource allocation.
Innovation Solution
User equipment (UE) dynamically selects antenna elements and forms wireless beams based on the context of data transmission, such as application type, to optimize spatial and performance characteristics for high or low performance requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all antenna elements are activated for data transmission, then transmission performance and reliability are improved, but power consumption and heat generation increase
Solution Approach 1:
The patent segments the antenna array into multiple subsets of antenna elements. Instead of activating all antenna elements simultaneously, the system divides them into groups and selectively activates specific subsets based on transmission requirements, application context, and channel conditions. This segmentation allows the system to maintain transmission reliability through diverse antenna selection while reducing power consumption by keeping only necessary antenna elements active.
Solution Approach 2:
The patent implements dynamic antenna element selection where the subset of active antenna elements changes adaptively based on varying transmission conditions, application types, and channel states. The system dynamically adjusts which antenna elements are activated rather than using a fixed configuration, enabling optimal balance between transmission reliability and power consumption for different operational scenarios.
2Reliability
If a narrow beam profile is used for high-performance applications, then transmission performance is improved, but device complexity and processing requirements increase
Solution Approach 1:
The patent applies different beam profiles (narrow or wide) locally according to specific application requirements and channel conditions rather than using a single uniform beam configuration for all transmissions. The system selects appropriate beam qualities dynamically - narrow beams for applications requiring high precision and reliability, and wide beams for applications prioritizing coverage and simplicity - thereby managing device complexity while maintaining transmission performance where needed.
3Use of energy by moving object
If antenna elements are selectively activated based on application context, then power efficiency is improved, but system complexity for context determination increases
Solution Approach 1:
The patent implements self-service mechanisms where the UE autonomously determines transmission context, selects appropriate antenna subsets, and configures beam profiles without requiring complex external control or coordination. The device uses locally available information such as application identifiers, buffer status, and channel conditions to make intelligent antenna selection decisions, thereby achieving power efficiency through context-aware operation while minimizing the complexity overhead of context determination.

AI summary
In an example method, a user equipment (UE) of a wireless network determines data for transmission between the UE and a base station (BS) of the wireless network; determines a context of the transmission of the data between the UE and the BS; selects, based on the context, one or more antenna elements of an antenna array of the UE; and forms one or more wireless beams using the one or more selected antenna elements. Further, the UE (i) transmits at least a first portion of the data to the BS using the one or more wireless beams, and/or (ii) receives at least a second portion of the data from the BS using the one or more wireless beams.
