Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If periodic interference measurements are performed across all beam pairs, then interference management reliability is improved, but resource overhead and latency increase
Solution Approach 1:
The patent segments the beam measurement process into two hierarchical levels: wide beam level and narrow beam level. At the wide beam level, beam relations are established and maintained. At the narrow beam level, interference measurements are performed only on selected beam pairs based on the wide beam relations. This segmentation allows the system to maintain reliability through structured beam management while reducing latency by avoiding exhaustive measurements across all narrow beam pairs.
2Reliability
If periodic interference measurements are performed across all beam pairs, then interference management reliability is improved, but resource overhead increases
Solution Approach 1:
The patent divides the interference measurement resource allocation into hierarchical levels. Wide beam configurations establish spatial relationships that guide narrow beam measurement selections. This segmentation enables the system to maintain reliable interference management through structured beam relations while significantly reducing the quantity of resources required by performing measurements only on relevant narrow beam pairs rather than all possible pairs.
Solution Approach 2:
The patent implements partial action by performing interference measurements only on selected narrow beam pairs that are relevant based on wide beam relations, rather than performing exhaustive measurements on all beam pairs. This partial measurement approach maintains sufficient interference management reliability while reducing resource overhead by avoiding redundant measurements on beam pairs that are unlikely to cause or experience significant interference.
3Productivity
If hierarchical beam relations are implemented, then productivity in beam management is improved, but device complexity increases
Solution Approach 1:
The patent segments beam management into hierarchical levels with clear separation of functions. Wide beam management handles high-level spatial relationships and beam pair selection, while narrow beam management handles detailed interference measurements and channel state information. This segmentation improves productivity by organizing complex beam management tasks into manageable layers, and the structured hierarchy actually reduces perceived device complexity by providing clear procedural guidelines for beam configuration and measurement.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first network entity may transmit, to a second network entity, beam configuration information associated with the first network entity, wherein the beam configuration information indicates hierarchical beam relations between one or more wide beams and a plurality of narrow beams. The first network entity may receive, from the second network entity, an indication of a scheduled interference measurement associated with a narrow beam of the plurality of narrow beams based at least in part on the beam configuration information associated with the first network entity. Numerous other aspects are described.
