摘要： Some embodiments of this disclosure include apparatuses and methods for reporting channel state information (CSI) for multiple spatial layers. The apparatuses and methods can include at least: determining, by a user equipment (UE), a precoding matrix indicator (PMI) for a set of precoding matrixes, wherein the PMI is determined based on a combination of digital Fourier transformation (DFT) spatial domain (SD) vectors, or based on DFT-based frequency domain (FD) compression; and transmitting, by the UE, the PMI to a next-generation NodeB (gNB).

摘要： Described is an apparatus of a User Equipment (UE) operable to communicate with an Evolved Node-B (eNB) on a wireless network. The apparatus may comprise a first circuitry and a second circuitry. The first circuitry may be operable to process a Downlink (DL) transmission carrying one or more Phase Tracking Reference Signal (PT-RSes). The second circuitry may be operable to generate an Uplink (UL) transmission carrying a Layer Indicator (LI) based at least on a number of PT-RS Antenna Ports (APs) associated with the PT-RSes.
