Paging Time Unit Determination for Bandwidth Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, particularly in LTE and 5G networks, determining the correct paging time unit for terminals is challenging due to varying time-frequency resource configurations and bandwidth requirements, leading to potential missed paging messages when the minimum bandwidth is exceeded.
Innovation Solution
A method and device for determining paging time units by receiving paging configuration information, identifying the type of paging time unit based on time-frequency resource information, SS block information, or preset bandwidth, and selecting appropriate time units to ensure the terminal can receive paging messages within the available bandwidth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the network uses varying time-frequency resource configurations for paging messages, then the system can support different bandwidth requirements, but terminals may miss paging messages when minimum bandwidth is exceeded
Solution Approach 1:
The paging time unit is segmented into multiple candidate time units with different bandwidth characteristics. The terminal segments the search space into multiple monitoring opportunities, allowing it to find at least one candidate that fits its bandwidth capability while maintaining reliable paging message reception.
Solution Approach 2:
The system dynamically adapts the paging message transmission to match terminal bandwidth capabilities. Different terminals receive paging messages in time units with appropriately configured bandwidth, allowing the system to maintain reliability across devices with varying bandwidth support.
2Reliability
If the terminal monitors all possible paging time units, then no paging messages are missed, but the terminal consumes excessive power
Solution Approach 1:
Instead of uniformly monitoring all paging time units, the terminal applies local quality by monitoring only those candidate time units whose bandwidth characteristics match its own capabilities. This selective monitoring reduces power consumption while maintaining reliable paging message reception.
Solution Approach 2:
The terminal autonomously determines its own bandwidth capability and selects appropriate candidate time units for monitoring based on self-assessment. This self-service approach allows the terminal to optimize its power consumption without external control while ensuring it monitors the correct paging opportunities.
3Measurement precision
If the paging configuration information includes detailed time-frequency resource information, then the terminal can accurately determine paging time units, but the signaling overhead increases
Solution Approach 1:
The network provides partial information in the paging configuration - specifically the SSB index - rather than complete time-frequency resource details. The terminal uses this partial information combined with its own bandwidth capability to derive the complete paging time unit identification, reducing signaling overhead while maintaining determination accuracy.
