Network-Controlled Repeater ON/OFF Control via Beam Indications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for appropriate control mechanisms in communication apparatuses, particularly Network-controlled Repeaters (NCRs), to manage the on-off operations effectively to prevent deterioration in communication quality, interference, and excessive power consumption.
Innovation Solution
The proposed solution involves implicit and explicit ON/OFF indication methods for NCRs, where the ON/OFF state is controlled based on beam indications or other communication control indications, ensuring coordinated operation with base stations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If explicit ON/OFF indication is used for NCR operation control, then control precision is improved, but signaling overhead increases
Solution Approach 1:
The patent combines the ON/OFF indication with beam indication by using the same DCI format and resource allocation mechanism. The NCR operation state is indicated through the beam indication field, merging two control functions into a single signaling structure, thereby reducing overhead while maintaining control precision
Solution Approach 2:
The beam indication mechanism is designed to serve multiple functions: it indicates both the beam direction for communication and the operational state (ON/OFF) of the NCR. This multi-functional approach eliminates the need for separate signaling for ON/OFF control, reducing overall signaling overhead
2Reliability
If NCR operation is continuously maintained, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic ON/OFF control of NCR operations based on scheduled beam indications. The NCR is activated only during specific time periods when beam indication signals are received, creating a periodic operation pattern that reduces power consumption while maintaining communication reliability during active periods
Solution Approach 2:
The system uses feedback mechanisms where the base station monitors communication conditions and sends beam indication signals to activate NCR only when needed. This feedback-based control ensures NCR operates reliably when communication quality requires it while remaining inactive during good conditions to save power
3Adaptability or versatility
If NCR operation is frequently switched, then adaptability to communication conditions is improved, but control complexity increases
Solution Approach 1:
By merging ON/OFF control with beam indication in the same DCI signaling structure, the patent simplifies the control mechanism. The NCR device only needs to monitor beam indication signals to determine operation state, reducing control complexity while maintaining adaptability to changing communication conditions through the beam management process
