Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The introduction of bandwidth part (BWP) technology in 5G communication systems causes inconsistent cognitions between layer 1 and layer 2 regarding resource block positions, requiring modifications to existing network architectures like nFAPI for accurate resource allocation.
Innovation Solution
A master base station and resource allocation indicating method that convert BWP configurations to common configurations, establishing a corresponding relation between local and common resource units, enabling correct resource unit positioning for distributed base stations using the layer 1-layer 2 split technology.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If BWP technology is introduced to increase system capacity and coverage, then resource allocation flexibility is improved, but inconsistency between layer 1 and layer 2 cognitions of resource block positions occurs
Solution Approach 1:
The patent introduces a correspondence relationship as an intermediary between BWP configuration and common configuration. This intermediary maps local resource unit identifiers in BWP to common resource unit identifiers, enabling consistent cognition between layer 1 and layer 2 while preserving BWP flexibility. The correspondence relationship acts as a translation layer that resolves the认知 inconsistency without sacrificing resource allocation adaptability.
Solution Approach 2:
The patent changes the parameter representation by introducing a mapping mechanism that transforms local resource identifiers to common resource identifiers. By modifying how resource positions are identified and communicated between layers, the system maintains both BWP configuration flexibility and cognition consistency. The parameter transformation occurs through the correspondence relationship that links different identifier systems.
2Manufacturing precision
If BWP configuration with independent parameter settings is used, then resource allocation precision is improved, but device complexity increases due to multiple configuration mappings
Solution Approach 1:
The patent applies preliminary action by pre-establishing the correspondence relationship between BWP configuration and common configuration before resource allocation occurs. The mapping table is prepared in advance, containing the relationships between local and common resource unit identifiers. This preliminary setup enables precise resource allocation without requiring complex real-time calculations, thereby reducing operational complexity while maintaining high allocation precision.
3Device complexity
If existing nFAPI architecture is used without modification, then system simplicity is maintained, but resource allocation accuracy deteriorates due to inconsistent resource block position cognition
Solution Approach 1:
The patent introduces a correspondence relationship as an intermediary layer within the existing nFAPI architecture. This intermediary does not fundamentally change the system architecture but adds a mapping mechanism that translates between different resource identifier systems. The approach maintains architectural simplicity while significantly improving resource block position accuracy by resolving the cognition inconsistency between layers.

AI summary
A master base station and a resource allocation indicating method are provided. The master base station and a distributed base station are based on a layer 1-layer 2 split technology. A bandwidth part (BWP) configuration is enabled. Different BWP configurations have different configurations in a frequency domain. The BWP configuration corresponds to continuous and part of the common resource units, and corresponds to a common configuration to generate a corresponding relation, which is related to a corresponding situation between identifications of the local resource units and the common resource units. The identifications of the local resource units are used in the BWP configuration to identify the local resource units, and the identifications of the common resource units are used in the common configuration to identify the common resource units. The corresponding relation is transmitted. Accordingly, the BWP can be applied to a transmission interface of layer 1-layer 2 split technology.
