Relay Beam Capability Reporting for 5G NR Signaling Overhead
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G NR networks lack detailed guidelines for beam capability reporting in relay-type wireless devices, leading to inefficiencies in beam training and increased signaling overhead, as they only report general beam patterns and spatial relationships without specifying the necessary information for beam characteristics like non-overlapped or partially-overlapped beams.
Innovation Solution
Proposing a method where a relay-type wireless device reports beam capability information indicating non-overlapped or partially-overlapped beams to the base station, which determines beam training information based on this data, reducing signaling overhead and enabling hierarchical beam management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If relay-type wireless devices report general beam patterns and spatial relationships without detailed beam characteristics, then device complexity is reduced, but beam training efficiency deteriorates
Solution Approach 1:
The patent applies local quality by differentiating the level of detail reported for different beam characteristics. Instead of reporting all beam parameters with uniform detail, the invention selectively reports specific local characteristics (non-overlapped or partially-overlapped beam information) that are most critical for beam training, while omitting less important details. This resolves the contradiction by providing just enough local detail to maintain efficiency without overall complexity increase.
2Productivity
If relay-type wireless devices report detailed beam capability information including non-overlapped or partially-overlapped beams, then beam training efficiency is improved, but signaling overhead increases
Solution Approach 1:
The patent extracts only the essential beam capability information needed for effective beam training - specifically the number of non-overlapped or partially-overlapped beams - while leaving out unnecessary detailed beam characteristics. This extraction approach maintains beam training efficiency by providing the critical information needed, while minimizing signaling overhead by omitting redundant details that do not contribute to the beam training process.
3Measurement precision
If relay-type wireless devices report comprehensive beam information, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The patent applies partial action by reporting only the necessary portion of beam capability information - specifically the count of non-overlapped or partially-overlapped beams - rather than providing exhaustive details about all beam characteristics. This partial reporting achieves sufficient measurement precision for beam training purposes while significantly reducing the time required for capability reporting, thus resolving the contradiction between precision and time.

AI summary
Examples pertaining to beam capability reporting in a relay-type wireless device are described. An apparatus may serve as a relay between a user equipment (UE) and a wireless node of a wireless network. An apparatus may also report its beam capability information for a wireless link between the apparatus and the UE to the wireless node. The beam capability information may indicate one or more non-overlapped or partially-overlapped beams.
