Assignee: QUALCOMM INCORPORATED
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 9:
10. An apparatus for wireless communication at a user equipment (UE), 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:
receive a training signal from a network node on a plurality of sub-carriers from multiple in-phase (I) and quadrature (Q) (IQ) modulators and multiple radio frequency (RF) antenna panels; and
transmit a feedback associated with a frequency dependent residual side band (FDRSB) based on the training signal to the network node,

wherein the at least one processor is configured to receive at least one tone of the training signal on a first subset of sub-carriers of the plurality of sub-carriers, the first subset of sub-carriers being configured symmetric to a second subset of sub-carriers with respect to a center frequency of the plurality of sub-carriers, and the second subset of sub-carriers being free of the at least one tone of the training signal.
