Solution Overview

Problem

Existing wireless communications systems face challenges in implementing refined Radio Resource Management (RRM) and interference control due to the exchange of resource status and load information on a cell basis, which limits their effectiveness in managing load balancing and interference.

Innovation Solution

The method involves transmitting resource status information and load information between base stations using service classification identifiers, allowing for precise RRM operations and interference control at a service level by distinguishing between different services such as eMBB, mMTC, and URLLC, enabling more refined network management.

VSEngineering Contradiction Analysis

1Measurement precision

If base stations exchange resource status information and load information on a cell basis, then the existing communication system can perform basic load balancing and interference control, but refined RRM operation and refined interference control cannot be achieved

Engineering Contradiction:

Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments resource status information and load information by service types (eMBB, mMTC, URLLC), dividing the previously unified cell-level information into service-specific components. This segmentation enables refined RRM operations and interference control for different services while maintaining manageable information structures through standardized reporting mechanisms.

Inventive Principle:
Principle #1Segmentation

2Productivity

If base stations deploy multiple base stations with different transmit power or different access types within a geographical range, then the capacity of the wireless communications system increases, but interference between base stations occurs

Engineering Contradiction:

Solution Approach 1:

The patent applies local quality by enabling differentiated interference control for different service types. Base stations can identify and control interference sources specific to each service (eMBB, mMTC, URLLC) based on the service classification identifiers in received information, allowing targeted interference management that preserves system capacity while protecting service-specific performance.

Solution Approach 1:

The patent segments resource status information by service types, enabling load balancing operations to be performed separately for eMBB, mMTC, and URLLC services. This segmentation allows the system to meet refined RRM operation requirements by making service-specific load management decisions based on service-classified resource status information.
