Abstract
Methods and apparatuses for determining phase tracking reference signal (PT-RS) for single frequency network (SFN) based PDSCH transmission are disclosed. A method comprises determining, for each of two PT-RS ports for SFN based PDSCH transmission, an associated DM-RS port with an indicated TCI state, wherein, one or multiple PDSCH layers are scheduled for the SFN based PDSCH transmission; determining, for each of the two PT-RS ports, an RE index in the RB containing PT-RS resources; and receiving the two PT-RS ports associated with two TCI states.

A method comprising:
- determining, for each of two phase tracking reference signal (PT-RS) ports for single frequency network (SFN) based physical downlink shared channel (PDSCH) transmission, an associated demodulation reference signal (DM-RS) port with an indicated transmission configuration indication (TCI) state, wherein one or multiple PDSCH layers are scheduled for the SFN based PDSCH transmission;
- determining, for each of the two PT-RS ports, resource element (RE) index in a resource block (RB) containing PT-RS resources;
- and
- receiving the two PT-RS ports associated with two TCI states.

A remote unit comprising:
- a processor that determines, for each of two phase tracking reference signal (PT-RS) ports for single frequency network (SFN) based physical downlink shared channel (PDSCH) transmission, an associated demodulation reference signal (DM-RS) port with an indicated transmission configuration indication (TCI) state, wherein one or multiple PDSCH layers are scheduled for the SFN based PDSCH transmission;
- and
- a receiver that receives the two PT-RS ports associated with two TCI states.
