Solution Overview

Problem

Existing communication systems face large signaling overheads due to terminals directly reporting direct current locations, including CC and BWP information, which is inefficient.

Innovation Solution

Terminals determine and report first information to network devices, which includes direct current location algorithm information, reducing the need to report CC and BWP details explicitly, allowing network devices to calculate direct current locations based on reported parameters.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If terminals directly report possible direct current locations including CC information, BWP information, and direct current location, then the network device can obtain accurate DC location information, but the signaling overhead becomes large

Engineering Contradiction:
ImproveDC location reporting accuracyVSAvoidsignaling overhead
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The patent extracts only the essential information needed for DC location determination (CC index and BWP index) from the complete DC location information, and reports these extracted parameters to the network device. The network device then uses pre-configured algorithms to reconstruct the full DC location information, thereby reducing signaling overhead while maintaining reporting accuracy.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of the terminal calculating and reporting complete DC location information directly, the patent inverts the process by having the terminal report only parameters (CC index, BWP index) and letting the network device perform the calculation using pre-configured algorithms. This inversion shifts the computational burden from the terminal to the network device, reducing uplink signaling overhead.

Inventive Principle:
Principle #13The other way round (Inversion)

2Measurement precision

If terminals report detailed CC and BWP information for each DC location, then the network device can precisely identify the DC location, but the complexity of the reporting mechanism increases

Engineering Contradiction:
ImproveDC location identification precisionVSAvoidreporting mechanism complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments the DC location information into distinct components: CC index, BWP index, and DC location offset. Each component is reported separately or used independently by the network device with pre-configured algorithms, simplifying the reporting mechanism while maintaining precise DC location identification capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent creates a universal reporting mechanism where the terminal reports parameters (CC index, BWP index) that can be used with pre-configured algorithms to determine DC locations for multiple BWPs and CCs. This multi-functional approach allows the same reporting mechanism to serve various DC location determination scenarios without increasing complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)
