Reconfigurable intelligent surface or repeater assisted synchronization signal block transmission and initial access

A network entity for wireless communication, comprising:

• a memory;
• and
• one or more processors, coupled to the memory, configured to:
• transmit a synchronization signal block (SSB) burst set including a first set of SSBs associated with direct transmission from the network entity and a second set of SSBs associated with a reconfigurable intelligent surface (RIS) or a repeater;
• and
• transmit system information including initial access information that is RIS assisted initial access information or repeater assisted initial access information, the initial access information identifying the second set of SSBs as being associated with the RIS or the repeater and the initial access information identifying a modulation signature associated with the RIS or the repeater.

A method of wireless communication performed by a user equipment (UE), the method comprising:

• receiving a synchronization signal block (SSB) transmitted by a base station;
• receiving system information that includes initial access information that is reconfigurable intelligent surface (RIS) assisted initial access information or repeater assisted initial access information, the initial access information identifying a set of SSBs that are associated with an RIS or a repeater and the initial access information identifying a modulation signature associated with the RIS or the repeater;
• and
• selecting between performing initial access using the SSB and searching for another SSB based at least in part on the initial access information.
