Beam Reporting Preference Selection for Wireless Beam Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, configuring all beams for beam reporting by a base station as Set A, when the number of beams of Set A is greater than those of Set B, leads to inefficient signaling overhead and potential exclusion of preferred UE beams without specific criteria, resulting in reduced reporting accuracy.
Innovation Solution
A method involving a user equipment (UE) that receives configuration information and downlink reference signals (DL RS), determines UE preferences based on measurements, and transmits information related to a second set of beams, optimizing beam reporting to reduce signaling overhead and maintain accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If all beams are configured as Set A for beam reporting, then beam reporting completeness is improved, but signaling overhead increases
Solution Approach 1:
The patent extracts only the necessary beam information by having the UE determine a reduced Set A from the full set of beams. Instead of reporting all configured beams, the UE selects and reports only the most relevant beams based on measurement criteria, thereby reducing signaling overhead while maintaining reporting accuracy for beam management decisions.
2Quantity of substance
If the number of beams in Set A is reduced to lower signaling overhead, then signaling efficiency is improved, but beam reporting accuracy deteriorates
Solution Approach 1:
The patent applies local quality by differentiating beams based on their individual characteristics and measurement results. Each beam is evaluated based on its specific properties (such as signal strength, quality metrics) and is selectively included in Set A accordingly. This ensures that beams with superior characteristics are prioritized for reporting, maintaining accuracy while reducing overall signaling overhead.
Solution Approach 2:
The patent utilizes parameter changes by dynamically adjusting the composition of Set A based on measurement parameters and UE preferences. The UE modifies the beam selection criteria and Set A configuration according to real-time measurement results, ensuring that the reduced set maintains representative accuracy for beam management operations.
3Measurement precision
If UE determines Set A based on measurement for Set B, then beam selection accuracy is improved, but device complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring the measurement framework and evaluation criteria before beam selection occurs. The network provides pre-defined measurement parameters and beam configuration templates, enabling the UE to perform systematic beam evaluation without complex real-time calculations. This prepares the necessary measurement infrastructure in advance, reducing processing complexity during actual beam selection.

AI summary
A method according to one embodiment of the present specification comprises the steps of: receiving configuration information including information related to at least one downlink-reference signal (DL RS); receiving the at least one DL RS; and transmitting information related to a terminal preference (UE preference) determined on the basis of a measurement of the at least one DL RS. The at least one DL RS is based on a plurality of DL RSs related to i) a first set of beams and/or ii) a second set of beams related to the first set. The information related to the UE preference is related to i) a configuration of the second set and/or ii) an attribute related to the second set of beams.
