摘要
Embodiments of a User Equipment (UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. The UE may receive an information element (IE) that includes: a higher layer parameter that indicates a plurality of modulation and coding scheme (MCS) thresholds; and another higher layer parameter that includes a plurality of resource block (RB) thresholds. The UE may determine a time density of phase tracking reference signal (PT-RS) to be transmitted by the UE based at least partly on a comparison between a MCS and the plurality of MCS thresholds. The UE may determine a frequency density of the PT-RS based at least partly on a comparison between a scheduled bandwidth and the plurality of RB thresholds. The UE may encode the PT-RS for transmission in accordance with the determined time density and the determined frequency density.
