Shared COT Signaling for Service-Specific Power Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in controlling how a base station transmits specific services in a shared Channel Occupancy Time (COT) initiated by a terminal device, as UEs cannot effectively manage power detection thresholds for different service types.
Innovation Solution
Implementing a method where devices send and receive indication information to indicate power detection thresholds or service types, with different thresholds corresponding to different service types, allowing network devices to transmit services accordingly in a shared COT.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single power detection threshold is used for COT sharing, then the system is simple to operate, but the base station cannot transmit different service types efficiently in the shared COT
Solution Approach 1:
The patent segments the single power detection threshold into multiple thresholds corresponding to different service types (e.g., eMBB, URLLC, mMTC). Each service type has its own configured power detection threshold, allowing the base station to distinguish and transmit different services within the shared COT based on their specific requirements.
Solution Approach 2:
The patent introduces dynamic indication information that can be sent from the base station to the UE, allowing the power detection threshold to be adjusted or selected dynamically during COT sharing. This enables the system to adapt to different service types without requiring manual reconfiguration, resolving the contradiction between operational simplicity and service transmission versatility.
2Productivity
If multiple power detection thresholds are configured for different service types, then the base station can transmit specific services efficiently, but the system complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where the base station sends indication information to the UE about which power detection threshold should be used for a particular service type. This feedback approach allows the system to manage multiple thresholds in an organized manner, reducing the complexity burden on the UE while maintaining high service transmission efficiency.
3Loss of time
If the UE initiates COT sharing without service type indication, then the process is simple and fast, but the base station cannot control which services to transmit
Solution Approach 1:
The patent applies preliminary action by having the base station pre-configure multiple power detection thresholds and service type mappings before COT sharing begins. When the UE initiates COT sharing, the base station can quickly send indication information to select the appropriate threshold without requiring lengthy negotiations, thus maintaining speed while enabling service control.
