Solution Overview

Problem

Current wireless communication systems lack sufficient information about the number of antenna panels in user equipment (UEs) with multiple antenna panels, leading to sub-optimal network decisions regarding power consumption and thermal overhead, which affects communication efficiency.

Innovation Solution

The system provides UE assistance information, including the number of antenna panels, relative power consumption, and thermal overhead, allowing network units to make informed decisions for beam selection and resource allocation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If network entities make decisions without sufficient UE antenna panel information, then device complexity is reduced, but communication efficiency and resource allocation quality deteriorate

Engineering Contradiction:
Improvecommunication efficiencyVSAvoidantenna panel information
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The patent applies preliminary action by having the UE transmit antenna panel information (number of panels, power consumption indicators, thermal overhead indicators) before the network entity makes beam selection or resource allocation decisions. This advance provision of information enables the network to optimize communications based on actual UE capabilities and conditions.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback by establishing a communication loop where the UE provides information about its antenna panel state to the network entity. This feedback mechanism allows the network to adapt its decisions (beam selection, resource allocation) based on real-time UE conditions, improving overall communication efficiency.

Inventive Principle:
Principle #23Feedback

2Productivity

If UE transmits detailed assistance information about antenna panels, power consumption, and thermal overhead, then resource allocation quality improves, but signaling overhead and processing complexity increase

Engineering Contradiction:
Improveresource allocation qualityVSAvoidinformation processing complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the UE assistance information into distinct, manageable components: number of antenna panels, power consumption indicators, and thermal overhead indicators. This segmentation allows the network entity to process each type of information separately and makes the overall system more manageable despite the increased information volume.

Inventive Principle:
Principle #1Segmentation

3Productivity

If network entities optimize beam selection without considering UE power consumption and thermal conditions, then communication performance is maximized, but UE power consumption and thermal overhead increase

Engineering Contradiction:
Improvecommunication performanceVSAvoidUE power consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent applies dynamics by enabling the network entity to adapt beam selection decisions based on dynamic UE conditions (power consumption indicators, thermal overhead indicators). Rather than using static optimization, the system dynamically adjusts communications to balance performance with UE energy and thermal constraints.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements parameter changes by allowing the network entity to modify communication parameters (beam selection, resource allocation) based on UE-provided information about power consumption and thermal conditions. This enables optimization that accounts for varying UE operational states.

Inventive Principle:
Principle #35Parameter changes

AI summary

Systems and methods for wireless communication with devices equipped with multiple antenna panels are provided. A UE may transmit UE assistance information (UAI) to a wireless communication device associated with other network information such as rank indicator (RI). The UAI may include an indication of a quantity of antenna panels in use, a relative power consumption indicator, and/or a thermal overhead indicator. This information may be used by the wireless communication device to determine a network configuration which reduces the power consumption and/or thermal overhead of the UE.
