one or more memories coupled with the one or more processors that store instructions that are operable, when executed by the one or more processors, to cause the apparatus to:
transmit, to a base station, a random access preamble to initiate a random access procedure;
receive, from the base station, a downlink message including:
a random access response (RAR) that includes a time domain resource allocation (TDRA) for a physical uplink channel, wherein a number of repetitions associated with transmitting the physical uplink channel is associated with a value of a transmission power control (TPC) command field; or
downlink control information (DCI) that includes a TDRA for retransmitting the physical uplink channel, wherein a number of repetitions associated with retransmitting the physical uplink channel is associated with one or both of a new data indicator field of the DCI or a hybrid automatic repeat request (HARQ) process number field of the DCI; and
