Original Abstract Submitted
Apparatuses and methods for uplink (UL) transmissions and receptions. A method performed by a user equipment (UE). The method includes transmitting capability information about an UL codebook for 3 antenna ports; receiving a configuration indicating a sounding resource signal (SRS) resource set comprising at least one SRS resource with 4 SRS ports, wherein one of the 4 SRS ports is muted; and transmitting a SRS from 3 of the 4 SRS ports. The method further includes receiving an indication indicating a transmit precoding matrix indicator (TPMI) for transmission of a physical uplink shared channel (PUSCH) and transmitting the PUSCH based on the indicated TPMI. The TPMI indicates a precoding matrix from the UL codebook for the 3 antenna ports.
