Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently managing inter-device physical feedback channels, particularly in the context of 6G systems, which require high data rates, low latency, and reliable connectivity, necessitating improved methods for determining when to drop such channels based on measurement values and threshold criteria.
Innovation Solution
A method and apparatus for wireless communication involving a first device that receives a reference signal related to a first beam, obtains a measurement value, and determines whether to drop an inter-device physical feedback channel based on this measurement value and a threshold, utilizing transceivers, processors, and memory to execute these operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If inter-device physical feedback channel transmission is continuously maintained, then communication reliability is improved, but system resource consumption and latency increase
Solution Approach 1:
The patent implements dynamic adaptation of feedback channel transmission by allowing UEs to adjust their feedback transmission behavior based on real-time beam measurement values and thresholds. The system transitions from static continuous feedback to dynamic conditional feedback, where the feedback channel is activated or dropped based on whether beam quality meets threshold requirements, thereby reducing latency while maintaining reliability only when necessary
Solution Approach 2:
The patent changes the operational parameters of the feedback channel based on measured beam quality metrics. By comparing measurement values against configurable thresholds, the system adjusts the feedback transmission state (transmit or drop), effectively using parameter-based control to balance reliability and latency requirements in different channel conditions
2Reliability
If beam-based communication is implemented for high data rates, then spectral efficiency is improved, but system complexity increases
Solution Approach 1:
The patent segments the feedback handling process into distinct measurement and decision stages. UEs separately perform beam measurement, compare against thresholds, and then make independent feedback transmission decisions. This segmentation simplifies the overall system complexity by breaking down the complex beam management task into manageable, standardized operations that can be executed autonomously by each UE
Solution Approach 2:
The patent enables UEs to autonomously manage their own feedback channel transmission based on local beam measurements and threshold comparisons. Each UE independently determines whether to transmit or drop feedback without requiring complex centralized coordination, thereby reducing overall system complexity while maintaining high spectral efficiency through beam-based communication

AI summary
Proposed is an operating method of a first device (100) in a wireless communication system. The method may comprise the steps of: receiving, from a second device (200), a reference signal related to a first beam used for reception of an inter-device physical shared channel; obtaining a measurement value for the reference signal; and determining, on the basis of the measurement value and a threshold value, whether to drop transmission of an inter-device physical feedback channel related to reception of the inter-device physical shared channel.
