Methods and apparatuses for prach repetition

A base station (BS), comprising:

• at least one memory;
• and
• at least one processor coupled with the at least one memory and configured to cause the base station to:
• transmit configuration information indicating a set of physical random access channel (PRACH) repetition numbers;
• or
• obtain the configuration information;
• and
• for each PRACH repetition number in the set of PRACH repetition numbers, determine at least one time period for PRACH repetition based on a corresponding PRACH repetition number, wherein each time period of the at least one time period includes a set of random access channel (RACH) occasions (ROs) for PRACH repetition.

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

• obtaining configuration information indicating a set of physical random access channel (PRACH) repetition numbers;
• determining a PRACH repetition number from the set of PRACH repetition numbers;
• and
• determining at least one time period for PRACH repetition based on the determined PRACH repetition number, wherein each time period of the at least one time period includes a set of random access channel (RACH) occasions (ROs) for PRACH repetition.

A processor for wireless communication, comprising:

• at least one controller coupled with at least one memory and configured to cause the processor to:
• obtain configuration information indicating a set of physical random access channel (PRACH) repetition numbers;
• select a PRACH repetition number from the set of PRACH repetition numbers;
• and
• determine at least one time period for PRACH repetition based on the selected PRACH repetition number, wherein each time period of the at least one time period includes a set of random access channel (RACH) occasions (ROs) for PRACH repetition.
