5G UE Paging Reception on Minimum Bandwidth Part
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The 5G mobile communication system faces inefficiencies in frequency domain resources due to the Frequency Division Multiplexing (FDM) of Synchronization Signal Blocks (SSBs) and paging channels on Band Width Parts (BWPs, particularly in high-frequency bands where UEs have varying bandwidth capabilities.
Innovation Solution
A method and device for receiving paging messages, where a UE receives paging configuration information including a BWP identifier, determining the number of BWPs supported, and configuring the paging message on the minimum bandwidth supported, allowing for efficient reception either through frequency hopping or optimal time-spent receiving modes based on the number of supported BWPs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If FDM of SSB and paging channel is performed on a BWP, then frequency domain resource utilization is improved, but frequency domain resource insufficiency occurs
Solution Approach 1:
The patent divides the BWP into different parts: one part for SSB transmission and another part for paging channel transmission. This segmentation allows both signals to coexist without resource conflict, resolving the contradiction between improving frequency domain resource utilization and ensuring resource sufficiency.
Solution Approach 2:
The patent introduces time domain dimension by configuring paging messages on specific slots and symbols within the BWP. This dimensional change allows frequency resources to be shared between SSB and paging channel while maintaining sufficiency through temporal separation.
2Device complexity
If paging message is configured on minimum band width, then device complexity is reduced, but reception time increases
Solution Approach 1:
The patent configures paging messages to be transmitted periodically on specific slots and symbols within the minimum bandwidth BWP. This periodic action allows UEs to efficiently receive paging messages without continuously monitoring all bandwidths, reducing complexity while maintaining acceptable reception timing.
Solution Approach 2:
The network pre-configures the minimum bandwidth BWP and paging message parameters before UE operation. This preliminary action allows UEs to operate with reduced complexity from the start, knowing exactly which bandwidth to monitor, while the network schedules paging messages at predetermined times to minimize reception delays.

AI summary
Provided are a paging message receiving method and device, a paging configuration method and device, a UE, a base station, and a computer-readable storage medium. The paging message receiving method includes: receiving paging configuration information from a base station, the paging configuration information including a Band Width Part (BWP) identifier of a BWP for receiving, by the UE, the paging message, and being configured on a minimum band width supported by the UE in a BWP corresponding to the BWP identifier; acquiring, according to the paging configuration information, the BWP identifier for receiving the paging message; determining a number of BWP(s)supported by the UE; and receiving, according to the number of BWP(s), the paging message on the BWP corresponding to the acquired BWP identifier, thereby avoiding the insufficiency of frequency domain resources caused by FDM of a SSB and a paging channel on a BWP.
