1. An apparatus for wireless communication at a network node, comprising:
a memory; and
at least one processor coupled to the memory and, based at least in part on information stored in the memory, the at least one processor is configured to:
transmit a training signal for a user equipment (UE) on a plurality of sub-carriers, the training signal transmitted via multiple in-phase (I) and quadrature (Q) (IQ) modulators and multiple radio frequency (RF) antenna panels;
receive a feedback associated with a frequency dependent residual side band (FDRSB) based on the training signal; and
apply an FDRSB correction filter to at least one signal to be transmitted to the UE, the FDRSB correction filter based on the feedback received from the UE.
