SSB Position plays a vital role in 5G

Did you know that 5G SSB Frequency domain position can influence and impact many KPIs, including Access time, UE Battery consumption, Handovers, and Interference?

Let`s discuss in this article, How SSB frequency domain position can impact above mentioned KPIs!

1- What main concerns and recommendations need to be considered when configuring the SSB Frequency position?

1- In case you have different Bandwidth configurations operating under the same frequency band. Locate SSB at the exact Frequency location for all sites. As this will reduce the unnecessary inter-frequency handovers and will also mitigate the interference caused by SSB <--> PDSCH

Example: n78 operating with 80Mhz at Site A and with 60Mhz at Site B

2- It`s recommended to configure the SSB frequency domain position at the bottom/start of the band, especially in 5G Standalone, to reduce the cell search time and, accordingly will, improve the access delay and UE Battery consumption.
