Inter-Frequency Reference Signal Spatial Mapping for Beam Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently managing beams across different frequency ranges, particularly in transitioning from lower frequency ranges to higher frequency ranges, which affects communication quality and efficiency.
Innovation Solution
The method involves receiving reference signals via a beam of a first frequency range associated with a set of beams of a second frequency range, and performing beam management based on these signals to optimize communication via the second frequency range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If beam management is performed independently for each frequency range, then beam management precision is maintained, but system complexity and resource consumption increase
Solution Approach 1:
The patent applies universality by using reference signals from the first frequency range to perform beam management for the second frequency range. The same reference signal infrastructure serves multiple frequency ranges simultaneously, reducing system complexity while maintaining beam management precision through spatial mapping relationships between frequency ranges.
2Productivity
If spatial mapping is used to associate beams between frequency ranges, then communication efficiency improves, but implementation complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-establishing spatial mapping relationships between beams of different frequency ranges using reference signals. This preliminary spatial association enables more efficient communication by allowing the system to leverage known spatial relationships rather than performing complete beam management procedures for each frequency range.
3Reliability
If reference signals are transmitted across multiple frequency ranges, then beam management effectiveness improves, but signal interference increases
Solution Approach 1:
The patent uses reference signals as an intermediary to establish spatial mapping relationships between frequency ranges. Rather than directly managing beams across frequency ranges which would cause interference, the reference signals serve as a mediator that carries spatial information, enabling indirect beam management that maintains effectiveness while reducing direct signal interference.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive one or more reference signals (RSs) via a beam of a first frequency range, the beam of the first frequency range being associated with a set of beams of a second frequency range. The UE may perform, based at least in part on the one or more RSs, beam management for communication via the second frequency range. Numerous other aspects are described.
