1. A non-transitory computer-readable medium storing instructions that, when executed by one or more processors of a User Equipment (UE), cause the UE to perform operations comprising:
processing a Downlink (DL) transmission carrying one or more Phase Tracking Reference Signals (PT-RSes); and
generating an Uplink (UL) transmission carrying one or more Layer Indicators (LIs) together with an associated Channel State Information (CSI) based at least on a number of PT-RS Antenna Ports (APs) associated with the one or more PT-RSes, wherein a PT-RS of the one or more PT-RSes is associated with an AP of a Demodulation Reference Signal (DMRS) AP group, wherein a number of the one or more LIs is equal to the number of PT-RS APs, and the number of the one or more LIs is jointly encoded with one or more of a CSI Resource Indicator (CRI), a Rank Indicator (RI), a Precoder Matrix Indicator (PMI), or a Channel Quality Indicator (CQI).
