Solution Overview

Problem

Current wireless communication networks lack flexibility in handling frequent changes of supported capabilities by user equipment (UE) due to static capability indication methods, which can lead to difficulties in combining certain capabilities, especially when UE is used as a relaying station.

Innovation Solution

A method where a wireless communication device dynamically indicates a set of capabilities and their combinations to the network, allowing for real-time adjustments based on operational conditions, using preconfigured bitmaps and limitations to signal supported combinations without interrupting connectivity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If UE capabilities are indicated in a static manner to the network, then the capability indication process is simple, but the network cannot handle frequent changes of supported capabilities

Engineering Contradiction:

Improvenetwork flexibility in handling capability changesVSAvoidcapability indication mechanism complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent transforms the static capability indication mechanism into a dynamic one by enabling UEs to periodically or event-triggered update their capability information without re-registering. The network stores capability profiles and actively monitors for updates, allowing real-time adaptation to changing operational conditions while maintaining connection continuity.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent pre-configures multiple capability profiles for a UE, where each profile defines a set of supported capabilities. The UE can switch between these pre-defined profiles based on current operational conditions, avoiding the need to re-indicate all capabilities from scratch and reducing signaling overhead.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If UE re-registers to update capability information, then the network has up-to-date capability information, but connectivity is interrupted

Engineering Contradiction:

Improvecapability information accuracyVSAvoidconnection continuity

Core Design Contradiction:

ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The patent implements a feedback mechanism where the UE periodically or event-triggered sends capability update information to the network without disconnecting. The network stores these updated profiles and uses them for subsequent resource allocation decisions, maintaining continuous connectivity while keeping capability information current.

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If multiple capability profiles are configured for a UE, then the UE can adapt to different operational conditions, but the signaling overhead increases

Engineering Contradiction:

ImproveUE adaptability to operational conditionsVSAvoidsignaling overhead

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent segments capability information into separate, manageable profiles. Each profile contains a specific set of capabilities relevant to particular operational conditions, allowing the network to request and process only the necessary profile information rather than handling all possible capability combinations at once.

Inventive Principle:

Principle #1Segmentation

AI summary

A wireless communication device (100) provides a first indication to the wireless communication network. The first indication indicates a set of at least two capabilities of the wireless communication device (100). Further, the wireless communication device (100) determines whether the wireless communication device (100) supports a combination of two or more of the capabilities and provides a second indication to the wireless communication network. The second indication indicates whether the combination of capabilities is supported by the wireless communication device (100).
