Network-Controlled Repeater Idle Mode for Selective Paging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network-controlled repeaters (NCRs) consume excessive power and resources by unconditionally forwarding all paging occasions, even when no messages are sent, leading to inefficiencies and increased operational costs.
Innovation Solution
The NCRs enter an idle mode, periodically waking up to monitor paging frames for PEI or DCI, and selectively forward PDSCH based on successful decoding, reducing unnecessary transmissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If NCR unconditionally forwards all paging occasions, then all paging messages are reliably transmitted to UEs, but power consumption and resource usage increase excessively
Solution Approach 1:
The NCR dynamically adjusts its forwarding behavior based on real-time conditions. It transitions between active forwarding state and idle state, monitoring paging occasions conditionally rather than unconditionally. This dynamic state adjustment allows the NCR to maintain reliability when needed while reducing power consumption during idle periods.
Solution Approach 2:
The NCR implements periodic monitoring of paging occasions instead of continuous forwarding. It wakes up at scheduled intervals to check for paging messages and only forwards when necessary. This periodic action pattern reduces overall power consumption while maintaining reliable message delivery when paging occasions actually occur.
2Use of energy by moving object
If NCR enters idle mode to save power, then power consumption decreases, but ability to forward messages promptly increases
Solution Approach 1:
The NCR performs preliminary actions by pre-configuring monitoring schedules and maintaining minimal listening capability during idle mode. It prepares to quickly transition to active state when paging occasions are detected, ensuring that while power consumption is reduced, the system remains ready to forward messages promptly when needed.
Solution Approach 2:
The NCR implements feedback mechanisms by monitoring paging occasion indicators and using this information to determine when to wake from idle mode. This feedback-driven approach ensures that the NCR only becomes active when there is actual paging traffic, balancing power savings with prompt message forwarding capability.
3Reliability
If NCR monitors every paging occasion, then no paging messages are missed, but resource utilization efficiency decreases
Solution Approach 1:
The NCR applies partial monitoring action by selectively monitoring only certain paging occasions based on configured patterns and indicators. Instead of monitoring every single paging occasion, it uses a subset of monitoring points that are sufficient to detect relevant paging messages while improving resource utilization efficiency.
Solution Approach 2:
The NCR extracts and monitors only the essential paging occasion indicators rather than processing every paging occasion in full. It takes out the critical monitoring elements (PEI, DCI) from the complete paging occasion set, achieving reliable detection with reduced resource consumption by focusing on key indicators only.

AI summary
Methods, systems, and devices for wireless communications are described. A network-controlled repeater (NCR) may enter an idle mode at a first radio (e.g., an NCR mobile termination (NCR-MT)) associated with the NCR. The NCR may forward, via a second radio (e.g., an NCR forwarder (NCR-FWD)) associated with the NCR, one or more transmissions of a downlink control information (DCI), a paging early indication (PEI), or both during a paging occasion of a paging frame while the first radio is in the idle mode. The NCR may selectively forward, via the second radio associated with the NCR, one or more paging messages or physical downlink shared channel (PDSCH) transmissions during a set quantity of symbols of the paging frame subsequent to the paging occasion while the first radio is in the idle mode. The selective forwarding may be based on successfully decoding the DCI or the PEI at the NCR.
