Ssb specific prach configuration

An apparatus comprising:

• at least one processor;
• and
• at least one non-transitory memory including computer program code;
• the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:
• determine that a repeater is present in a cell of the apparatus;
• transmit, to a user equipment, information comprising at least:
• an indication of a first physical random access channel configuration, wherein the first physical random access channel configuration is associated with an identifier of at least one first radio beam, and
• an indication of a second physical random access channel configuration, wherein the second physical random access configuration is at least partially different from the first physical random access channel configuration, wherein the second physical random access channel configuration is associated with an identifier of at least one second radio beam, wherein the at least one second radio beam comprises, at least, a radio beam for communicating via the repeater;
• and
• receive, from the user equipment, a radio access preamble on a radio beam according to a physical random access channel configuration indicated with the transmitted information.

An apparatus comprising:

• at least one processor;
• and
• at least one non-transitory memory including computer program code;
• the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:
• receive, from a user equipment, a radio access preamble on a radio beam according to a physical random access channel configuration, wherein the physical random access channel configuration comprises at least one of:
• a first physical random access channel configuration, wherein the first physical random access channel configuration is associated with an identifier of at least one first radio beam, or
• a second physical random access channel configuration, wherein the second physical random access configuration is at least partially different from the first physical random access channel configuration, wherein the second physical random access channel configuration is associated with an identifier of at least one second radio beam, wherein the at least one second radio beam comprises a radio beam for communicating via the apparatus;
• and
• transmit the received radio access preamble to a network node.
