Paging PDCCH Repeat Transmission for Low-Capability NR Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of implementing repeat transmission for the paging Physical Downlink Control Channel (PDCCH) in low-capability NR terminals has not been addressed in existing technologies, which is necessary to improve reception performance in scenarios where coverage may be compromised due to reduced terminal complexity.
Innovation Solution
A method is introduced for low-capability NR terminals to determine PDCCH monitoring occasions and perform blind detection on candidate PDCCH sets with multiple retransmissions, utilizing a network device's configuration to enhance reception by combining multiple transmissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network side transmits paging messages continuously until the terminal responds, then the terminal can be successfully paged, but the network resources are wasted when the terminal is lost or unavailable
Solution Approach 1:
The terminal performs preliminary actions by actively monitoring and detecting paging messages during idle and inactive states, and by proactively sending response messages or notification messages before the network needs to transmit paging messages, thereby reducing unnecessary network resource consumption while ensuring reliable communication establishment
2Speed
If the terminal monitors paging messages frequently to respond quickly, then the response speed is improved, but the terminal's power consumption increases
Solution Approach 1:
The terminal dynamically adjusts its paging monitoring behavior based on its current state (idle or inactive) and the actual need for communication, rather than continuously monitoring at fixed intervals, thereby achieving fast response when needed while conserving energy during periods when communication is not required
Solution Approach 2:
The terminal serves itself by autonomously detecting paging messages and determining when to send response or notification messages without requiring continuous network prompting, thereby reducing power consumption while maintaining responsive communication

AI summary
Disclosed in the present application is a repeat transmission paging method, comprising: a terminal device determines physical downlink control channel (PDCCH) monitoring occasions on at least one synchronization signal block (SSB) beam, the maximum number of the PDCCH monitoring occasions being a product of the number of SSB beams of a paging PDCCH transmitted by a network device and the maximum number of retransmissions of the paging PDCCH on each SSB beam, and receives first indication information, the first indication information being used for determining channel state indication reference signal resource information, and the channel state indication reference signal resource information being used for the terminal device in an unconnected state to perform downlink synchronization. Also disclosed in the present application are another repeat transmission paging method, an electronic device, and a storage medium.
