Indication of a repetition factor for a third message of a random access procedure

An apparatus for wireless communication at a base station, comprising:

• a memory;
• and
• one or more processors, coupled to the memory, configured to cause the apparatus to:
• receive, from a user equipment (UE), a first message of a random access procedure;
• transmit, to the UE, a second message of the random access procedure that indicates information for an uplink grant for a third message of the random access procedure, the information including a modulation and coding scheme (MCS) indication and a transmit power control (TPC) indication;
• and
• receive, from the UE, one or more repetitions of a physical uplink shared channel (PUSCH) carrying the third message, wherein a repetition factor for the one or more repetitions is indicated by at least one of the MCS indication or the TPC indication;
• wherein the repetition factor for the one or more repetitions is indicated by the MCS indication if the repetition factor for the one or more repetitions satisfies a threshold, and the repetition factor for the one or more repetitions is indicated by the TPC indication if the repetition factor for the one or more repetitions does not satisfy the threshold.

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

• transmitting, to a base station, a first message of a random access procedure;
• receiving, from the base station, a second message of the random access procedure that indicates information for an uplink grant for a third message of the random access procedure, the information including a modulation and coding scheme (MCS) indication and a transmit power control (TPC) indication;
• and
• transmitting, to the base station, one or more repetitions of a physical uplink shared channel (PUSCH) carrying the third message, wherein a repetition factor for the one or more repetitions is indicated by at least one of the MCS indication or the TPC indication;
• wherein the repetition factor for the one or more repetitions is indicated by the MCS indication if the repetition factor for the one or more repetitions satisfies a threshold, and the repetition factor for the one or more repetitions is indicated by the TPC indication if the repetition factor for the one or more repetitions does not satisfy the threshold.
