Group of SSBs is called SSB Burst. SSB burst is transmitted within the half frame of total frame. again this SSB burst repeats with a periodicity which is signaled by higher layer parameter ssb-periodicityServingCell.
The size of SSB burst can be 4/ 8/ 64 SSBs based on the frequency and Sub Carrier Spacing.

So max size of SSB burst possible in NR is 64 for frequency > 6Ghz and SCS = 120kHz/240 Khz.

Hi,

Is there any relation between SSB burst and number of Beam's

commented Sep 20, 2019 by Jaganathan

Hi,

Yes, Number of Beams is same as number of SSBs.
So if 'N' number of SSBs are configured per SSB burst , 'N' number of Beams gets transmitted per SSB burst.
