Solution Overview

Problem

Existing UE technologies autonomously select panel activation or deactivation, leading to increased complexity and potential inefficiency in wireless communications.

Innovation Solution

A base station initiates panel activation or deactivation at a UE through configuration messages, allowing the UE to select panels based on these instructions for uplink transmissions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If UE autonomously selects panels for uplink transmissions, then UE has flexibility in panel selection, but UE complexity increases

Engineering Contradiction:

Improvepanel selection flexibilityVSAvoidUE complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The base station acts as an intermediary that provides panel activation configurations to the UE through control messages. The UE does not autonomously decide which panels to activate, but rather follows network instructions, thereby reducing UE complexity while maintaining adaptability through network-controlled panel selection

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

Instead of the UE making autonomous panel selection decisions (bottom-up approach), the base station makes the decisions and instructs the UE (top-down approach). This inversion of the decision-making hierarchy reduces UE complexity while preserving system flexibility through network intelligence

Inventive Principle:

Principle #13The other way round (Inversion)

2Extent of automation

If UE autonomously manages panel activation, then UE can independently optimize transmissions, but power management efficiency decreases

Engineering Contradiction:

Improveautonomous panel managementVSAvoidpower management efficiency

Core Design Contradiction:

Extent of automationVSUse of energy by moving object

Solution Approach 1:

The base station serves as an intelligent mediator that receives information about UE panel capabilities and transmission requirements, then optimizes panel activation configurations to balance power consumption with transmission performance, achieving better power management efficiency than autonomous UE decisions

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If UE autonomously selects panels, then UE can adapt to channel conditions, but interference management capability is reduced

Engineering Contradiction:

Improvechannel condition adaptationVSAvoidinterference management

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The base station receives feedback about UE panel capabilities and channel conditions, then uses this information to make informed panel activation decisions that simultaneously adapt to channel conditions and manage interference effectively, combining local knowledge with network-wide perspective

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The base station acts as an intermediary that coordinates panel selections across multiple UEs to manage interference, while still allowing each UE to adapt to its own channel conditions through network-provided activation configurations

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

Methods, systems, and devices for wireless communications are described. In some example, a base station may facilitate panel activation or deactivation at a user equipment (UE). For example, a UE including a set of panels may establish a connection with a base station. The base station may transmit an activation configuration message activating or deactivating a subset of panels at the UE. Based on the activation configuration message, the UE may select one or more panels from the set of panels and transmit an uplink transmission to the base station using the selected one or more panels.
