Abstract: The present disclosure provides apparatuses, systems, methods, and machine readable storage medium for physical uplink shared channel (PUSCH) transmission between a user equipment (UE) and a base station, based on a robust codebook. In an embodiment, a UE, including circuitry operable to: report a UE capability of the UE to a base station, wherein the UE capability comprises a number of phase tracking reference signal (PT-RS) antenna ports (NPT-RS) supported by the UE; decode control signaling received from the base station, wherein the control signaling comprises at least one parameter to indicate a precoder selected from a codebook based on at least the NPT-RS; and perform physical uplink shared channel (PUSCH) transmission according to the indicated precoder; wherein the codebook is predefined or configured based on different numbers of PT-RS antenna ports and different waveforms, in the UE and the base station.
