Power control for transmissions with time-based artificial noise

An apparatus for wireless communication at a user equipment (UE), comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive a first reference signal from a network entity over a first time interval;
• apply a first pseudo-noise signal to a first repetition of a first signal to obtain a second signal, wherein the first pseudo-noise signal is based at least in part on a first estimated channel state information corresponding to the first reference signal, a first gain parameter, and a first phase parameter, and wherein the first gain parameter and the first phase parameter are based at least in part on a second gain parameter and a second phase parameter of a second pseudo-noise signal applied to a second repetition of the first signal to obtain a third signal that is transmitted to the network entity over a second time interval occurring prior to the first time interval;
• and
• transmit the second signal to the network entity over a third time interval occurring after the first time interval.
