1. One or more non-transitory computer-readable media having instructions that, when executed by one or more processors, cause an apparatus to:
process scheduling information to determine a schedule of a physical uplink shared channel (PUSCH) transmission with a plurality of repetitions, wherein the plurality of repetitions include at least two repetition sets to be respectively transmitted with at least two transmit beams;
determine a number of phase tracking reference signal (PTRS) ports to be used for transmitting PTRSs associated with each of the at least two repetition sets;
cause the PUSCH transmission to be transmitted with the plurality of repetitions using the at least two transmit beams; and
cause the PTRSs to be transmitted by the number of PTRS ports.
