Paging Power-Saving Signal Configuration for NR-Lite Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing discontinuous reception (DRX) mechanisms struggle to meet low power consumption requirements for low-cost and low-power terminals, such as New Radio Lite (NR-Lite) terminals, necessitating a more effective power-saving mechanism, particularly in idle and inactive states.
Innovation Solution
Configuring a power-saving signal for terminals to monitor paging messages in idle or inactive states, allowing them to selectively skip monitoring periods based on the detection of the power-saving signal, and adjusting configurations based on terminal capabilities through auxiliary information reporting.

1Use of energy by moving object
If traditional DRX mechanism is used for low-cost terminals, then device complexity is reduced, but power consumption requirements cannot be met
Solution Approach 1:
A power-saving signal is introduced as an intermediary between the network device and the terminal. The network device sends power-saving signal configuration information to the terminal, which then uses this signal to determine whether to monitor paging messages during idle or inactive states. This intermediary mechanism enables fine-grained power control without requiring complex terminal-side decision-making algorithms.
Solution Approach 2:
The monitoring behavior of the terminal is made dynamic through the power-saving signal. Instead of fixed periodic monitoring, the terminal dynamically adjusts its paging message monitoring based on the power-saving signal received from the network. The terminal can switch between monitoring and non-monitoring states, allowing adaptive power consumption adjustment according to actual network conditions and terminal battery status.
2Reliability
If terminals continuously monitor paging messages, then message reception reliability is improved, but power consumption increases
Solution Approach 1:
The terminal monitors paging messages periodically rather than continuously, based on the power-saving signal configuration. The network device controls when the terminal should wake up to monitor paging messages by sending power-saving signals at specific intervals. This periodic monitoring approach maintains reliable message reception while significantly reducing power consumption compared to continuous monitoring.
Solution Approach 2:
The network device provides feedback to the terminal through power-saving signal configuration information, indicating whether the terminal should monitor paging messages in idle or inactive states. This feedback mechanism allows the network to control terminal power consumption based on actual data transmission needs, ensuring messages are received reliably only when necessary while saving power during periods without data activity.
