Paging Occasion Determination in 5G Wireless Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wireless communication systems face challenges in efficiently determining paging occasions (PO) for transmitting and receiving paging messages, particularly in 5G communication systems where multiple POs are required within a single paging DRX cycle.
Innovation Solution
The proposed solution involves a method and apparatus for determining POs, where a terminal receives information from a base station about the number of paging frames in a discontinuous reception (DRX) cycle and the number of POs for a paging frame. The terminal then identifies a paging frame and an index of a PO based on this information and monitors paging messages in one or more physical downlink control channels (PDCCH) according to the identified index.

1Productivity
If multiple POs are configured within a single paging DRX cycle in 5G systems, then the flexibility and efficiency of paging message management is improved, but the device complexity and difficulty of determining paging occasions increases
Solution Approach 1:
The paging DRX cycle is segmented into multiple paging frames (PF), and each PF is further segmented into multiple paging occasions (PO). This hierarchical segmentation allows the system to distribute paging messages across multiple time resources, improving management efficiency while providing structured methods for determining each PO's location.
Solution Approach 2:
The patent introduces dynamic parameters including variable numbers of POs per PF (Ns), configurable offsets between POs within a PF, and flexible DRX cycle lengths. These dynamic configurations allow the system to adapt to different traffic patterns and device requirements, improving overall efficiency while maintaining manageable complexity through standardized determination procedures.
2Quantity of substance
If the number of POs per paging frame is increased, then the capacity for handling multiple paging messages is improved, but the complexity of identifying and monitoring specific POs increases
Solution Approach 1:
The patent employs feedback mechanisms where the network configures parameters (Ns, offsets, PF indices) that are transmitted to UEs, enabling them to independently determine PO locations. This feedback loop allows the system to handle multiple paging messages efficiently while UEs can accurately identify their specific POs using the provided configuration information and standardized formulas.
Solution Approach 2:
Each UE autonomously determines its paging occasions using standardized formulas based on network-provided parameters and its own identity. This self-service approach allows UEs to independently calculate PO locations without complex centralized coordination, enabling high paging message capacity while keeping individual UE complexity manageable.
3Adaptability or versatility
If flexible configuration of POs is implemented, then the adaptability to different network scenarios is improved, but the device complexity for configuration and monitoring increases
Solution Approach 1:
The patent creates a universal paging framework that can adapt to various network scenarios through configurable parameters. The same basic structure (DRX cycle → paging frames → paging occasions) serves multiple purposes: supporting different traffic loads, accommodating various device types, and working across different frequency bands. This multi-functionality improves adaptability while maintaining consistent determination procedures that limit complexity growth.
