The SSB (Synchronization Signal Block) in 5G contains the Primary Synchronization Signal (PSS), Secondary Synchronization Signal (SSS), and the Physical Broadcast Channel (PBCH). The PSS and SSS are used by devices to achieve time and frequency synchronization with the cell. The PBCH carries essential system information that the device needs to access the network, such as the Master Information Block (MIB). These signals and channels are crucial for initial cell search and identification processes, allowing devices to establish and maintain connection with the network
