Random access PUSCH enhancements

1. A method for wireless communication performed by a user equipment (UE), comprising:

determining a first repetition level for an initial transmission of a Physical Uplink Shared Channel (PUSCH) transmission in a random access procedure and a second repetition level for a retransmission of the PUSCH transmission based at least in part on:

identifying, when the UE does not receive the single transmission, the plurality of values from a technical specification; and

transmitting, as part of the random access procedure, the initial transmission of the PUSCH transmission, according to a first quantity of repetitions associated with the first repetition level, and the retransmission of the PUSCH transmission, according to a second quantity of repetitions associated with the second repetition level,

wherein the first quantity of repetitions is a same or different as the second quantity of repetitions.

determine a first repetition level for an initial transmission of a Physical Uplink Shared Channel (PUSCH) transmission in a random access procedure and a second repetition level for a retransmission of the PUSCH transmission based at least in part on:

receiving, in a single transmission before a start of the random access procedure, a plurality of values that are each associated with a different repetition level of a plurality of repetition levels that includes the first repetition level and the second repetition level, wherein at least one of the plurality of values is associated with the initial transmission of the PUSCH transmission and the retransmission of the PUSCH transmission, or

identifying, when the apparatus does not receive the single transmission, the plurality of values from a technical specification; and

transmit, as part of the random access procedure, the initial transmission of the PUSCH transmission, according to a first quantity of repetitions associated with the first repetition level, and the retransmission of the PUSCH transmission, according to a second quantity of repetitions associated with the second repetition level,

wherein the first quantity of repetitions is a same or different as the second quantity of repetitions.

12. The apparatus of claim 11 , wherein the instructions, operable to cause the apparatus to transmit at least one of the initial transmission of the PUSCH transmission or the retransmission of the PUSCH transmission, are operable to cause the apparatus to:

transmit the initial transmission of the PUSCH transmission with a same symbol allocation in each slot where the initial transmission of the PUSCH transmission is transmitted according to the first repetition level, or

transmit the retransmission of the PUSCH transmission with the same symbol allocation in each slot where the retransmission of the PUSCH transmission is transmitted according to the second repetition level.

13. The apparatus of claim 11 , wherein the first repetition level and the second repetition level are further based at least in part on a random access response message.

14. The apparatus of claim 11 , wherein the first repetition level and the second repetition level are further based at least in part on downlink control information (DCI) scrambled by a temporary cell random network temporary identifier (TC-RNTI).

15. The apparatus of claim 11 , further comprising instructions operable to cause the apparatus to identify, when the apparatus does not receive the single transmission, the plurality of values from the technical specification.

16. The apparatus of claim 11 , wherein at least one of the plurality of values is for all apparatuses in a cell.

17. The apparatus of claim 11 , wherein at least one of:

a first value is for a first type of apparatus, or
