Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automated allocation and configuration of reference signal resources is implemented, then device complexity and error rate are reduced, but implementation complexity of the automation system increases
Solution Approach 1:
The system performs self-configuration of reference signal resources by automatically determining orthogonality relationships between adjacent cells and configuring resources accordingly, eliminating the need for manual operator intervention and reducing operational complexity
Solution Approach 2:
The system pre-configures reference signal resources during network setup or reconfiguration events, determining orthogonality relationships in advance and establishing resource allocations before actual data transmission begins, thereby simplifying ongoing operations
2Manufacturing precision
If deep understanding of 3GPP standards is required for resource allocation, then configuration accuracy can be maintained, but ease of operation deteriorates
Solution Approach 1:
The system automatically determines orthogonality relationships between reference signal resources of adjacent cells using standardized algorithms, eliminating the need for operators to manually understand complex 3GPP standard requirements while maintaining configuration accuracy
Solution Approach 2:
The system incorporates feedback mechanisms that monitor configuration outcomes and adjust resource allocations to maintain orthogonality, ensuring compliance with 3GPP standards through automated validation and correction rather than relying on operator expertise

AI summary
Automated allocation and configuration of reference signal resources relating to channel state information on a radio access network (RAN) can be performed. An allocator can allocate respective reference signal profiles associated with respective profile index values to respective cells of RAN based on respective profile index values associated with a profile type determined, from a group of profile types, based on cell relation topology information, wherein allocation can be performed to result in respective zero power reference signal (ZP-RS) resources, associated with respective reference signal profiles allocated to respective adjacent cells, being orthogonal with respect to each other. In each reference signal profile, ZP-RS resource can be orthogonal to non-zero power reference signal (NZP-RS) resource. Based on respective reference signal profiles, a configurator can configure respective parameters of respective resources, comprising respective ZP-RS resources and respective NZP-RS resources, associated with respective reference signal profiles on respective cells.
