Synchronization Signal Block System Information Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the context of 5G wireless communication systems, there is a challenge in efficiently receiving system information when it does not exist in the synchronization raster from which a synchronization signal block is detected, leading to increased overhead and reduced communication efficiency.
Innovation Solution
The method involves detecting a first synchronization signal block configured with PSS, SSS, and PBCH at a specific frequency position, determining the presence or absence of system information within a first synchronization raster, and if system information is absent, determining a second synchronization raster with existing system information based on a system information indicator in the PBCH.

Engineering Contradiction Analysis
1Reliability
If the base station transmits system information on all frequency bands, then the user equipment can receive system information, but the overhead increases and communication efficiency decreases
Solution Approach 1:
The patent applies local quality by differentiating the transmission of system information across different frequency bands. Instead of uniformly transmitting system information on all bands, the base station transmits system information only on specific bands where it is needed, while omitting it from other bands. This selective transmission approach reduces overhead in bands where system information is not required, while maintaining reliable reception in bands where it is necessary.
Solution Approach 2:
The patent implements partial action by having the base station transmit system information only on a subset of frequency bands rather than all available bands. The base station determines which frequency bands require system information transmission based on network conditions and user equipment requirements, thereby avoiding excessive transmission on bands where system information is not needed.
2Reliability
If the base station transmits system information on all frequency bands, then the user equipment can access the network, but the time required for system information acquisition increases
Solution Approach 1:
The patent applies local quality by transmitting system information only on specific frequency bands where network access is actually needed. This localized transmission approach allows user equipment to quickly identify and acquire system information from the appropriate bands without wasting time searching through all frequency bands, thereby reducing the overall time required for system information acquisition while maintaining reliable network access.
Solution Approach 2:
The base station performs preliminary determination of which frequency bands require system information transmission before actually transmitting the information. This preliminary action allows the system to prepare and transmit system information only when and where needed, reducing the time user equipment spends acquiring system information by avoiding unnecessary transmissions on irrelevant bands.

AI summary
The present invention discloses a method for a user equipment to receive system information in a wireless communication system. Particularly, the method is characterized in detecting a first synchronization signal block configured with a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS) and a Physical Broadcasting Channel (PBCH) at a specific frequency position, determining a presence or non-presence of system information corresponding to the first synchronization signal block within a first synchronization raster corresponding to a specific frequency position based on a system information indicator included in the PBCH, and if the system information corresponding to the first synchronization signal block is determined as not existing, determining a second synchronization raster having system information exist therein based on the system information indicator.
