Ssb transmission in holographic-mimo system

A method of wireless communication at a user equipment (UE), comprising:

• identifying a beam type of at least one of one or more two-dimensional (2D) beams for at least one first synchronization signal block (SSB) of a plurality of SSBs or one or more three-dimensional (3D) beams for at least one second SSB of the plurality of SSBs;
• and
• receiving, from a base station, at least one of the at least one first SSB via the one or more 2D beams or the at least one second SSB via the one or more 3D beams, a beam type of the at least one of the one or more 2D beams or the one or more 3D beams being associated with at least one of one or more frequency resources or one or more primary synchronization signal (PSS) or secondary synchronization signal (SSS) sequences.
