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 (N) 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 N; 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.

Physical uplink shared channel (PUSCH) transmission based on robust codebook

Embodiments of a Generation Node-B (gNB), User Equipment (UE) and methods for communication are generally described herein. The gNB may map data symbols to resource elements (REs) of virtual resource blocks (VRBs). The gNB may interleave the data symbols, on a per-VRB basis, to spatial layers of a multi-layer multiple-input multiple-output (MIMO) transmission. The data symbols may be interleaved based on different interleave patterns of VRB indexes for the spatial layers. The gNB may map the interleaved data symbols of the spatial layers to REs of physical resource blocks (PRBs) for orthogonal frequency division multiplexing (OFDM) transmission.
