1. A method for wireless communications at a user equipment (UE), comprising:
receiving, from a first wireless node via a first channel, a first transmission comprising a first artificial noise (AN) signal combined with a first data signal, wherein the first AN signal is generated based on channel state information (CSI) of the first channel;
receiving, from a second wireless node via a second channel, a second transmission comprising a second AN signal combined with a second data signal, wherein the second AN signal is generated based on CSI of the second channel and is different from the first AN signal, and wherein the first AN signal and the second AN signal are generated using a same pseudo-random noise and a same rotation angle; and
determining a data message based on the first transmission and the second transmission.
