SSB Indication Method for 5G Network Power Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G systems, dynamic changes to SSBs on the network side lead to unnecessary resource waste as user equipment (UE) continues to perform measurements and access based on outdated SSB patterns.
Innovation Solution
An SSB indication method where the network side device sends first indication information to UE, indicating the current state and configuration of SSBs, allowing UE to perform targeted operations related to the transmission state of SSBs.

Engineering Contradiction Analysis
1Use of energy by stationary object
If the network side dynamically disables/enables SSBs to save power, then network power consumption is reduced, but user equipment continues to perform measurements and access based on outdated SSB patterns causing resource waste
Solution Approach 1:
The network side sends indication information to UE to provide feedback about the current SSB transmission state. This feedback mechanism ensures UE receives real-time updates about which SSBs are enabled or disabled, allowing UE to adjust its measurement and access operations accordingly, thereby eliminating resource waste while maintaining network power saving benefits
Solution Approach 2:
Indication information acts as an intermediary between the network side and UE. This intermediary carries the state of SSB transmission from the network side to the UE, enabling the UE to understand and adapt to dynamic SSB changes without direct intervention in the SSB transmission itself
2Ease of operation
If UE continues to perform measurements based on pre-change SSB pattern, then measurement operations are simplified, but resource waste increases due to outdated SSB information
Solution Approach 1:
The network side sends indication information about SSB state changes to UE in advance, before UE performs measurement operations. This preliminary action ensures UE has the latest SSB configuration information, allowing UE to perform measurements efficiently without wasting resources on disabled SSBs

AI summary
An SSB indication method includes UE receives first indication information sent by a network side device, where the first indication information is used to indicate related information of an SSB of the network side device. UE performs a target-related operation based on the first indication information, where the target-related operation is an operation related to a transmission state of the SSB. The related information of the SSB includes at least one of the following that the SSB is in a disabled state or an enabled state, a disabled time or an enabled time of the SSB, a disabled pattern or an enabled pattern of the SSB, validity of an RACH occasion corresponding to the SSB, or a state mask of the SSB on an RACH occasion corresponding to the SSB.
