Csi report with cqi values

A method performed by a user equipment (UE), the method comprising:

• transmitting a set of parameters corresponding to an antenna configuration of the UE, wherein the antenna configuration comprises information on at an antenna grouping or a coherence grouping across antenna ports of the UE;
• transmitting a set of sounding reference signals (SRSs) over the antenna ports based on the antenna configuration;
• and
• receiving at least one transmit precoding matrix indicator (TPMI) based on the set of SRSs, the TPMI corresponding to an uplink (UL) codebook-based transmission.

A base station for wireless communication, comprising:

• at least one memory;
• and
• at least one processor coupled with the at least one memory and configured to cause the base station to:
• receive a set of parameters corresponding to an antenna configuration of a user equipment (UE), wherein the antenna configuration comprises information on an antenna grouping or a coherence grouping across antenna ports of the UE;
• receive a set of sounding reference signals (SRSs) over antenna ports of the base station, based on the antenna configuration;
• and
• transmit at least one transmit precoding matrix indicator (TPMI) based on the set of SRSs, the TPMI corresponding to an uplink (UL) codebook-based transmission.
