Unifying Message for Downlink Beam Management Over Multiple Groups
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-frequency wireless communications, such as millimeter Wave (mmW) signals, face high free-space path loss, requiring effective beam management techniques to adapt beam directions due to user equipment mobility, but existing methods lack a unified approach for managing beams across multiple groups of paired links.
Innovation Solution
A unifying message for downlink beam management is introduced, which includes configuration parameters like beam settings, spreading sequence settings, and beam management protocols, allowing for efficient evaluation and selection of transmit and receive beams, and their respective groups, to optimize beam pairing and signal transmission/reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beam management techniques are used to identify and adapt beam directions for high-frequency wireless communications, then signal quality is improved, but the complexity of managing multiple groups of beam paired links increases
Solution Approach 1:
The patent segments beam management by introducing a unified message structure that separately configures multiple groups of beam paired links (MGBPL). Each group can be independently managed with its own beam settings, spreading sequence settings, and protocol parameters, allowing complex beam management to be divided into manageable segments while maintaining overall system coordination
Solution Approach 2:
The unified message structure serves multiple functions simultaneously: it configures beam settings, assigns spreading sequences, defines beam management protocols, and manages multiple groups of beam paired links all through a single standardized message format. This multi-functional approach reduces the number of separate management procedures needed
2Productivity
If multiple beams are simultaneously evaluated and adapted during beam management procedure, then beam management efficiency is improved, but the configuration complexity increases
Solution Approach 1:
The patent divides the beam management configuration into distinct segments within the unified message: beam settings segment, spreading sequence settings segment, and protocol parameters segment. This segmentation allows efficient simultaneous evaluation of multiple beams while keeping configuration organized and manageable through structured sections
Solution Approach 2:
The unified message structure performs preliminary configuration actions by pre-defining beam settings, spreading sequences, and protocol parameters before the actual beam management procedure begins. This advance configuration enables efficient real-time beam evaluation and adaptation during the procedure without adding configuration complexity during execution

AI summary
A transmit-receive-point (TRP) may send a beam management configuration message to a user equipment (UE) that includes downlink beam management configuration parameters to use for an ensuing beam management procedure between the TRP and the UE. The beam management configuration message may specify various parameters associated with TRP/UE beams that are to be evaluated during the beam management procedure, directional transmission/reception capabilities of the TRP (e.g., how many transmit-beams and/or receive-beams the TRP is capable of using for simultaneous direction reception/transmission, etc.), spreading sequence parameters (e.g., which spreading sequence, or spreading sequence group, is to be used during the beam management procedure), and/or beam management protocol information.
