Original Abstract Submitted

Apparatuses and methods for multiple transmissions of a physical random access channel (PRACH). A method for includes identifying a set of numbers of repetitions for the PRACH preamble transmission and a first mapping among values of a PRACH mask index and a set of groups of PRACH occasions and receiving a downlink control information (DCI) format for a physical downlink control channel (PDCCH) order that indicates: a first value for a PRACH preamble index, a second value for a synchronization signal and physical broadcast channel (SS/PBCH) block index, and a third value for the PRACH mask index. The method further includes determining a number of repetitions from the set of numbers of repetitions and based on the third value and the first mapping, a group of PRACH occasions and transmitting the PRACH preamble with the number of repetitions over the group of PRACH occasions.
