Abstract
Methods and apparatuses for phase tracking reference signal are disclosed. A method comprises configuring a PT-RS with N PT-RS antenna ports when a ‘Transmission Configuration Indication (TCI)’ field in DCI indicates N TCI states, wherein N is 2 or more; associating each PT-RS antenna port with one DM-RS antenna port; and transmitting the PT-RS with the N PT-RS antenna ports.
