Paging Occasion Indication for Lower-Power 5G UE Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G communication systems face challenges in efficiently transmitting and receiving data, particularly in IoT environments, with a need to reduce power consumption associated with monitoring paging occasions (POs) in user equipment (UEs).
Innovation Solution
A method and apparatus are introduced for a UE and base station to transmit and receive indication information about the presence of paging messages across multiple POs in a paging cycle, allowing the UE to determine which POs to monitor, thereby reducing unnecessary power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE monitors all paging occasions in a paging cycle, then the reliability of receiving paging messages is improved, but the power consumption increases
Solution Approach 1:
The base station performs preliminary action by transmitting indication information before the UE monitors paging occasions. This indication information预先 indicates whether paging messages will be transmitted in upcoming POs, allowing the UE to make informed decisions about monitoring, thus avoiding unnecessary power consumption while ensuring reliable reception when needed
Solution Approach 2:
The UE dynamically adjusts its monitoring behavior based on received indication information. When the indication shows no paging messages, the UE skips monitoring those POs to save power; when paging messages are indicated, the UE monitors accordingly. This dynamic adjustment resolves the contradiction between reliable reception and power consumption
2Use of energy by moving object
If the UE skips monitoring some paging occasions, then the power consumption is reduced, but the reliability of receiving paging messages may deteriorate
Solution Approach 1:
The base station provides feedback through indication information that tells the UE whether paging messages are present in upcoming POs. This feedback mechanism ensures that when the UE skips monitoring, it does so safely without missing actual paging messages, thus maintaining reliability while reducing power consumption
3Adaptability or versatility
If the base station transmits paging messages in multiple paging occasions, then the flexibility of paging transmission is improved, but the signaling overhead increases
Solution Approach 1:
The paging transmission is segmented into multiple POs within a paging cycle, with indication information provided for each PO. This segmentation allows flexible transmission across multiple occasions while the indication information efficiently signals which POs contain paging messages, managing signaling overhead through structured division
Solution Approach 2:
The system uses periodic paging cycles with multiple POs distributed throughout. Indication information is transmitted periodically to indicate which POs will contain paging messages. This periodic structure provides transmission flexibility while managing signaling overhead through regular, predictable patterns

AI summary
A communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method performed by a terminal comprises: receiving, from a base station, information indicating whether at least one paging message is to be transmitted in at least one paging occasion (PO) among a plurality of POs configured with the UE; identifying that the at least one paging message is to be transmitted in the at least one PO based on the information; and monitoring the at least one PO for receiving the at least one paging message.
