Solution Overview

Problem

Current radio frequency communication technologies face a bottleneck in capability signaling due to the increasing number of supported band combinations, leading to excessive signaling size and inefficiency in indicating UE capabilities for carrier aggregation and dual connectivity.

Innovation Solution

The method involves transmitting information about operating band combinations using either a supported or unsupported indicator, optimizing signaling by using positive or negative indications based on the number of supported combinations, and employing indexes or bitmaps to reduce signaling size, allowing the network to request specific capabilities as needed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the number of supported band combinations is increased to support more carrier aggregation and dual connectivity options, then the adaptability and versatility of the system is improved, but the signaling size and complexity increase excessively

Engineering Contradiction:
Improvenumber of supported band combinationsVSAvoidsignaling size
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the capability signaling into two parts: a compact indication of supported band combination categories (using bitmaps or indices) and detailed capability information that is only exchanged when needed. This segmentation reduces the baseline signaling size while preserving the ability to support many band combinations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies partial action by transmitting only the essential capability information (band combination support categories) in the initial signaling, rather than transmitting all possible detailed capability parameters. The network can then request additional detailed information selectively based on actual needs, reducing unnecessary signaling overhead.

Inventive Principle:
Principle #16Partial or excessive action

2Loss of information

If detailed capability information is transmitted for all possible band combinations, then the completeness of capability information is improved, but the signaling efficiency deteriorates

Engineering Contradiction:
Improvecompleteness of capability informationVSAvoidsignaling efficiency
Core Design Contradiction:
Loss of informationVSProductivity

Solution Approach 1:

The patent extracts and transmits only the most essential capability information (support for band combination categories) in the initial signaling message. Detailed capability parameters are extracted and transmitted separately only when the network actually needs them for specific configurations, thereby maintaining information completeness while improving signaling efficiency.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent performs preliminary action by establishing a framework of supported band combination categories in advance. This preliminary information allows the network to make initial decisions about which band combinations to use, and only then request detailed capability parameters if needed, avoiding unnecessary transmission of all possible detailed information upfront.

Inventive Principle:
Principle #10Preliminary action

AI summary

A method includes transmitting information from an apparatus regarding at least one operating band combination. The information regarding the at least one operating band combination may comprise at least one of an index comprising a plurality of operating band combinations, and a bitmap relating to the index of operating band combinations. The method also includes selecting by the apparatus either a supported indicator or an unsupported indicator regarding the information. The method further includes transmitting, by the apparatus, the selected indicator.
