Paging Record Delivery Rule for Bandwidth Part Selection in 5G
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G communication systems face inefficiencies in paging message transmission due to the need to deliver the same paging records to all initial bandwidth parts (BWPs), leading to increased bandwidth and power consumption, especially when dealing with a large number of UEs that select different SSBs.
Innovation Solution
A method where UEs receive a paging record delivery rule, determine a specific BWP based on this rule, and re-select a cell to receive paging messages through that BWP, allowing for differentiated paging record transmission across BWPs, reducing the need for all BWPs to receive identical messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the same paging records are transmitted to all initial BWPs to ensure all UEs receive paging messages, then the reliability of paging delivery is improved, but the bandwidth consumption and power consumption increase
Solution Approach 1:
The patent segments the paging record transmission by dividing initial BWPs into different groups (first group and second group). Different paging records are transmitted to different BWP groups based on UE camped states, rather than transmitting identical paging records to all BWPs. This segmentation allows the system to maintain reliable paging delivery to relevant UEs while reducing unnecessary bandwidth and power consumption associated with transmitting duplicate paging records across all BWPs.
2Reliability
If the same paging records are transmitted to all initial BWPs to ensure all UEs receive paging messages, then the reliability of paging delivery is improved, but the bandwidth consumption increases
Solution Approach 1:
The patent segments the paging record transmission by dividing initial BWPs into different groups (first group and second group). Different paging records are transmitted to different BWP groups based on UE camped states, rather than transmitting identical paging records to all BWPs. This segmentation allows the system to maintain reliable paging delivery to relevant UEs while reducing unnecessary bandwidth consumption associated with transmitting duplicate paging records across all BWPs.
3Adaptability or versatility
If multiple CD-SSBs are transmitted within a wideband carrier to distribute UEs and reduce power consumption, then the adaptability of the system is improved, but the complexity of paging message management increases
Solution Approach 1:
The patent segments initial BWPs into different groups and associates each group with specific camped states. This segmentation provides a systematic framework for managing paging messages across multiple CD-SSBs, reducing the complexity of tracking which UEs are camped on which BWPs and ensuring paging messages are delivered to the appropriate groups.
Solution Approach 2:
The patent applies different paging record transmission strategies to different BWP groups based on their association with specific camped states. This local quality approach allows the system to optimize paging message management for each BWP group individually, rather than applying a uniform management strategy across all BWPs, thereby reducing overall system complexity.

AI summary
The disclosure provides a method and an apparatus for receiving a paging message in an environment of a 5G communication system. In an aspect, the disclosure is directed to a method of receiving a paging message for a UE compatible with a 5G communication system. The method would include not limited to: receiving a paging record (PR) delivery rule; entering into a power saving mode; determining a bandwidth part (BWP) according to the PR delivery rule; re-selecting to a cell which corresponds to the BWP which has been determined; and receiving a paging message transmitted through the BWP by the cell.
