Solution Overview

Problem

Existing communication technologies for multi-carrier cells (SCOMX) lack practical implementations for resource configuration and scheduling, leading to inefficiencies in throughput and increased common signaling overhead.

Innovation Solution

The method involves determining configuration information for multiple resource blocks within a cell or bandwidth part, and receiving scheduling information to perform data transmission and/or reception on these blocks, including parameters such as resource starting location, width, and subcarrier spacing, to optimize resource utilization and reduce overlap.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple carriers are configured for a serving cell (SCOMX), then data transmission throughput is improved, but device complexity and scheduling difficulty increase

Engineering Contradiction:
Improvedata transmission throughputVSAvoidscheduling complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the multiple carriers into multiple resource block groups, where each group is associated with a specific carrier. This segmentation allows the terminal to process and schedule resources carrier by carrier, reducing the overall scheduling complexity while maintaining the throughput benefits of multi-carrier operation. The segmentation is implemented through configuration information that divides resource blocks into distinct groups corresponding to different carriers.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a new dimension of organization by grouping resource blocks according to carrier association rather than treating all resource blocks uniformly. This dimensional change in resource organization allows the system to manage multiple carriers more efficiently by adding a carrier-dimension to the resource scheduling structure, thereby reducing complexity.

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

2Adaptability or versatility

If configuration information is provided for multiple resource blocks across multiple carriers, then resource utilization flexibility is improved, but signaling overhead increases

Engineering Contradiction:
Improveresource configuration flexibilityVSAvoidcommon signaling overhead
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent merges the configuration information for multiple resource blocks by introducing a unified resource block group indication mechanism. Instead of providing separate configuration information for each resource block, the system combines them into groups that can be indicated more efficiently. This merging reduces the amount of common signaling overhead while preserving the flexibility to configure multiple resource blocks across different carriers.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If resource blocks are allocated without carrier association, then scheduling simplicity is maintained, but resource overlap and interference increase

Engineering Contradiction:
Improvescheduling simplicityVSAvoidresource overlap and interference
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The patent applies local quality by associating specific resource block groups with specific carriers, creating a localized relationship between resources and carriers. This ensures that resource blocks are allocated in a carrier-specific manner, preventing overlap and interference between carriers while maintaining scheduling simplicity through the grouped structure. Each resource block group has the local quality of being tied to a specific carrier's characteristics.

Inventive Principle:
Principle #3Local quality
