5G Paging Beam Segmentation for UE Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G communication systems face inefficiencies in transmitting synchronization signals, system information, and paging messages due to the need for beam sweeping across multiple radiation directions, leading to increased power consumption and resource wastage in UE devices.
Innovation Solution
The base station sends synchronization signals and paging indication information through a single beam, allowing UE devices to determine if they are paged without needing to monitor multiple beams, thereby reducing monitoring duration and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beam sweeping is used to send synchronization signal and paging message through multiple beams, then coverage and reliability are improved, but UE power consumption increases due to needing to monitor multiple beams
Solution Approach 1:
The patent segments the beam monitoring process into two distinct phases: a first beam for acquiring SSB and paging indication information, and a second beam for receiving paging messages. This segmentation allows UE to limit initial monitoring to just the first beam, reducing power consumption while maintaining reliable paging delivery through the structured two-phase approach
Solution Approach 2:
The patent implements preliminary action by having the base station send paging indication information through the first beam before the UE needs to monitor the second beam. This preliminary indication allows UE to determine in advance whether paging is intended for them, avoiding the need to continuously monitor multiple beams and thereby reducing power consumption while ensuring reliable message delivery
2Reliability
If UE monitors multiple beams to acquire SSB and paging information, then information acquisition reliability is improved, but monitoring duration and resource usage increase
Solution Approach 1:
The patent divides the information acquisition process into segmented stages where different beams serve different purposes. The first beam handles SSB and paging indication acquisition, while the second beam handles paging message reception. This segmentation allows UE to complete critical information acquisition faster by focusing initial monitoring on the first beam only
Solution Approach 2:
The base station performs preliminary action by transmitting paging indication information through the first beam before requiring UE to monitor the second beam. This preliminary indication enables UE to make informed decisions about whether to continue monitoring, thereby reducing overall monitoring duration while maintaining reliable information acquisition
3Area of stationary object
If beam sweeping is implemented for system information transmission, then system coverage is improved, but network resource consumption increases
Solution Approach 1:
The patent segments the beam usage strategy so that the first beam is dedicated to transmitting SSB and paging indication information, while the second beam transmits paging messages. This segmentation optimizes network resource consumption by assigning specific functions to specific beams, avoiding redundant transmissions across all beams while maintaining comprehensive cell coverage

AI summary
The present disclosure provides an information transmission method and apparatus, and a computer-readable storage medium, and belongs to the field of communication. The method includes: sending a synchronization signal block (SSB) and paging indication information through a first beam, wherein the paging indication information is configured to identify user equipment (UE) paged by a base station in a cell served by the base station; and sending a first control resource set (CORSET) through a second beam, wherein the first CORSET includes a plurality of physical downlink control channels (PDCCHs), and the plurality of PDCCHs comprised in the first CORSET carry first downlink control information (DCI) configured to instruct the UE paged by the base station to acquire a paging message according to the first DCI. A technical solution of the present disclosure can reduce monitoring duration of the first UE, thereby reducing power consumption of the first UE.
