Solution Overview

Problem

User Equipment (UE) lack a mechanism to inform the network of its capabilities to receive control information from both base stations configured for newer and older mobile communication standards, leading to inefficiencies in communication.

Innovation Solution

The UE transmits a UE capability information message indicating support for both a first and second mobile communication capability, including sets of value pairs related to monitoring occasions for control channels on different component carriers, allowing it to detect control information on multiple mobile communication standards.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the UE transmits detailed capability information for multiple mobile communication standards, then the network can configure communication more effectively, but the complexity of the capability message increases

Engineering Contradiction:
Improvecapability to receive control information from different standardsVSAvoidcapability message structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The capability message is segmented into separate indicator fields for different mobile communication standards. Each standard (e.g., first standard and second standard) has its own capability indicator, allowing the UE to independently signal support for each standard without creating a complex combined structure. This segmentation simplifies the overall message structure while maintaining comprehensive capability information.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The capability information is organized along a new dimension of mobile communication standards rather than listing all capabilities in a single flat structure. By introducing the dimension of standard-specific capability indicators, the message achieves comprehensive coverage of multi-standard support while maintaining a structured and manageable format.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If the network configures communication for both newer and older standards, then compatibility is improved, but the configuration complexity increases

Engineering Contradiction:
Improvecompatibility with different standardsVSAvoidcommunication configuration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The communication configuration is segmented into standard-specific configurations. The network can independently configure parameters for UEs supporting the first mobile communication standard, UEs supporting the second standard, or both. This segmentation allows flexible configuration without requiring complex rule sets to handle all possible standard combinations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The configuration approach is made dynamic by enabling the network to adaptively select which standard(s) to configure based on the UE's indicated capabilities. The network can dynamically adjust the configuration complexity - using simple single-standard configuration when appropriate and more complex multi-standard configuration only when the UE indicates support for multiple standards.

Inventive Principle:
Principle #15Dynamics
