User equipment, base station and method

A base station, comprising:

• transmission circuitry configured to transmit, to a user equipment (UE), one or plurality of synchronization signal and physical broadcasting channel blocks (SSBs), and to send system information including a first parameter indicating a first reference signal received power (RSRP) threshold and a second parameter indicating second RSRP thresholds, wherein each of the second RSRP thresholds is associated with a certain number of multiple physical random access channel (PRACH) transmissions;
• and
• reception circuitry configured to receive, from the UE, one or plurality of PRACH transmissions on one or plurality of PRACH occasions which are associated with a first SSB selected by the UE among the one or plurality of SSBs based on the first RSRP threshold and the second RSRP thresholds.

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

• receiving, from a base station, one or plurality of synchronization signal and physical broadcasting channel blocks (SSBs);
• selecting a first SSB from the one or plurality of SSBs based on a first reference signal received power (RSRP) threshold and determining whether to perform multiple physical random access channel (PRACH) transmissions based on second RSRP thresholds, wherein each of the second RSRP thresholds is associated with a certain number of multiple physical random access channel (PRACH) transmissions;
• and
