Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If time and frequency resources are mapped to beams of a network node, then spectral efficiency is improved, but device complexity increases
Solution Approach 1:
The patent segments the time and frequency resources into distinct portions, each mapped to specific beams of the network node. This segmentation allows for targeted resource allocation to different spatial directions, improving spectral efficiency by avoiding interference between beams while managing complexity through structured resource division.
Solution Approach 2:
The patent applies local quality by allocating specific time and frequency resources to specific beams based on their individual characteristics and requirements. Each beam receives customized resource allocation optimized for its spatial direction and service requirements, thereby improving overall spectral efficiency while maintaining manageable device complexity through localized optimization.
2Productivity
If resource allocation is aligned with beam-specific characteristics, then communication efficiency is improved, but system complexity increases
Solution Approach 1:
The patent implements local quality by tailoring resource allocation to match beam-specific characteristics such as spatial direction, channel conditions, and service requirements. This localized resource optimization improves communication efficiency by ensuring each beam receives appropriate resources while the systematic approach to beam management keeps complexity manageable.
Solution Approach 2:
The patent utilizes parameter changes by dynamically adjusting time and frequency resource allocations based on beam characteristics and network conditions. This allows the system to optimize communication efficiency for each beam while adapting to changing conditions, managing complexity through parameter-based control rather than structural complexity.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may receive, from a parent network node, an indication of a mapping of time and frequency resources to a set of beams of the network node. The network node may receive one or more communications for forwarding via the set of beams using a set of time and frequency resources. The network node may forward the one or more communications via one or more beams of the set of beams based at least in part on the one or more communications being associated with the set of time and frequency resources, the set of time and frequency resources being mapped to the one or more beams according to the mapping of the time and frequency resources to the set of beams of the network node. Numerous other aspects are described.
