Wireless Paging Groups for Explicit Time-Domain Resource Location
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems lack an explicit solution for determining the time domain resource location for a terminal group to receive paging indication information, leading to inefficiencies in power consumption and network overheads.
Innovation Solution
A method is provided where a corresponding PO group is set for a terminal group, enabling the network device to send paging indication information on specific time domain resources, allowing terminals to specify the location for receiving this information, thereby optimizing power saving and reducing network overheads.

1Use of energy by moving object
If a terminal group is used to transmit paging early indication (PEI) to reduce terminal power consumption and network overheads, then power consumption and network overheads are reduced, but there is no explicit solution for determining the time domain resource location corresponding to the terminal group
Solution Approach 1:
The paging occasion (PO) resources are segmented into multiple PO groups, where each PO group corresponds to a specific terminal group. This segmentation allows terminals to identify their designated PO group and determine the time domain resource location based on group-specific configuration, resolving the ambiguity of resource location determination while maintaining power saving benefits
Solution Approach 2:
The network device pre-configures the correspondence between terminal groups and PO groups, and pre-determines the time domain resource locations for each PO group before actual paging operations. This preliminary configuration eliminates the need for complex real-time determination, reducing both power consumption and operational complexity
2Loss of substance
If paging indication information is transmitted without specifying time domain resource locations for terminal groups, then network overheads are reduced, but resource utilization efficiency deteriorates
Solution Approach 1:
Different PO groups are assigned to different terminal groups with specific time domain resource locations, creating local optimization where each terminal group receives paging indications at dedicated resources. This local quality assignment improves resource utilization efficiency without increasing overall network overheads, as the configuration is done once and reused

AI summary
The present application provides a wireless communication method, a terminal, and a network device. One example method includes: receiving, by a terminal in a first terminal group, PEI sent by a network device, wherein terminal belongs to a terminal group, the PEI indicates whether at least one terminal in the terminal group is to receive paging indication information, and the terminal group corresponds to a paging occasion (PO) group.
