Paging Indication Grouping for 5G UE Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In current 5G wireless communication systems, User Equipment (UE) in RRC_Idle/RRC_Inactive states receive unnecessary power consumption due to false alarms from paging messages not intended for them, as they monitor every paging cycle for potential messages, even if the 5G-S-TMSI is not included, leading to energy wastage.
Innovation Solution
The proposed solution involves grouping paging indication information and splitting it across multiple signals/channels, where large-scale information is carried on one signal/channel and small-scale information on another, allowing UE to skip unnecessary receptions based on partial paging indication, thereby reducing false alarms and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UE monitors every paging cycle for potential messages, then paging reliability is improved, but power consumption increases due to false alarms
Solution Approach 1:
The paging indication information is segmented into two parts: a first part carried on a first signal/channel and a second part carried on a second signal/channel. The UE first receives and processes the first part to perform preliminary judgment, and only if the first part indicates a potential match does the UE proceed to receive and process the second part. This segmentation allows the UE to avoid complete paging message reception when not intended, significantly reducing power consumption while maintaining reliable paging detection.
2Reliability
If UE receives complete paging indication information, then false alarm reduction is improved, but unnecessary receptions increase power consumption
Solution Approach 1:
The UE performs preliminary action by receiving and processing the first part of the paging indication information before committing to receiving the complete paging message. This preliminary judgment based on the first part allows the UE to identify and skip unnecessary paging message receptions, reducing both false alarms and power consumption by avoiding complete reception when the paging message is not intended for the UE.
3Device complexity
If paging indication information is transmitted on a single signal/channel, then transmission simplicity is improved, but UE cannot skip unnecessary receptions
Solution Approach 1:
The paging indication information is divided into two parts transmitted on different signals/channels. The first part is transmitted on a first signal/channel and the second part on a second signal/channel. This segmentation enables the UE to perform incremental processing: first evaluating the first part, and only proceeding to receive the second part if the first part indicates a potential match. This resolves the contradiction by maintaining manageable transmission complexity while enabling power-saving skipping behavior.

AI summary
Techniques are described to perform paging related operation or power saving related operation. An example wireless communication method includes receiving, by a communication device in a low power radio resource control (RRC) state, a first signal that includes a first set of parameters, and performing, by the communication device, a paging related operation based at least on the first set of parameters or a power saving related operation based at least on the first set of parameters.
