Precoder prediction for scell using pcell csi

A method of a base station (BS) in a wireless communication system, the method comprising:

• receiving an uplink (UL) sounding reference signal (SRS) on a primary cell (PCell);
• identifying, based on the UL SRS, spatial information associated with a frequency within a center frequency gap between a UL and a downlink (DL);
• identifying, based on the spatial information, one or more wideband (WB) precoders for at least one user equipment (UE) camping in a secondary cell (SCell);
• and
• transmitting, to the UE, a signal based on the one or more WB precoders.

A non-transitory computer-readable medium comprising program code, that when executed by at least one processor, causes an electronic device to:

• receive an uplink (UL) sounding reference signal (SRS) on a primary cell (PCell);
• identify, based on the UL SRS, spatial information associated with a frequency within a center frequency gap between a UL and a downlink (DL);
• identify, based on the spatial information, one or more wideband (WB) precoders for at least one user equipment (UE) camping in a secondary cell (SCell);
• and
• transmit, to the UE, a signal based on the one or more WB precoders.
