Service-Based Resource Status Exchange for Refined Interference Control
Find Innovative SolutionsGenerate Solutions
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.
Engineering Contradictions & Design Principles
Engineering 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
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.
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
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.
3Productivity
If base stations perform load balancing or load control operations, then the load of the cell can be reduced, but the requirement for refined RRM operation cannot be met with cell-level information
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.

AI summary
Embodiments of the present invention disclose an information transmission method and a radio access network device, and relate to the communications field, to resolve a problem that a refined RRM operation and refined interference control are difficult to implement when resource status information and load information are exchanged on a cell basis. A specific solution is as follows: A first base station receives resource status information from a second base station, where the resource status information includes a service classification identifier and a resource status corresponding to the service classification identifier; or the first base station receives load information from the second base station, where the load information includes a service classification identifier and a load corresponding to the service classification identifier, and the service classification identifier is a service type identifier or slice identification information. The embodiments of the present invention are used in an information transmission process.
