A method of wireless communication performed by a user equipment, UE, comprising: determining that a phase tracking reference signal, PTRS, port is to be shared among a plurality of physical downlink shared channels, PDSCHs, transmitted by a plurality of transmit receive points, TRPs; receiving PTRS pilot signals on one or more PDSCHs of the plurality of PDSCHs; and using the PTRS pilot signals for phase tracking estimation for the plurality of PDSCHs based at least in part on the determination that the PTRS port is to be shared among the plurality of PDSCHs; characterized in that the determination that the PTRS port is to be shared among the plurality of PDSCHs is based at least in part on: a determination that the plurality of PDSCHs are scheduled by the same downlink control information, a determination that the plurality of PDSCHs carry the same transport block, an indication that one or more PTRS ports or one or more demodulation reference signal, DMRS, ports associated with the plurality of PDSCHs are quasi co-located with respect to Doppler shift, a determination that the plurality of PDSCHs are scheduled to completely overlap in a time domain, a determination that the plurality of PDSCHs belong to the same component carrier or the same bandwidth part of the component carrier, or a combination thereof. determining that a phase tracking reference signal, PTRS, port is to be shared among a plurality of physical downlink shared channels, PDSCHs, transmitted by a plurality of transmit receive points, TRPs; receiving PTRS pilot signals on one or more PDSCHs of the plurality of PDSCHs; and using the PTRS pilot signals for phase tracking estimation for the plurality of PDSCHs based at least in part on the determination that the PTRS port is to be shared among the plurality of PDSCHs; characterized in that the determination that the PTRS port is to be shared among the plurality of PDSCHs is based at least in part on: a determination that the plurality of PDSCHs are scheduled by the same downlink control information, a determination that the plurality of PDSCHs carry the same transport block, an indication that one or more PTRS ports or one or more demodulation reference signal, DMRS, ports associated with the plurality of PDSCHs are quasi co-located with respect to Doppler shift, a determination that the plurality of PDSCHs are scheduled to completely overlap in a time domain, a determination that the plurality of PDSCHs belong to the same component carrier or the same bandwidth part of the component carrier, or a combination thereof. a determination that the plurality of PDSCHs are scheduled by the same downlink control information, a determination that the plurality of PDSCHs carry the same transport block, an indication that one or more PTRS ports or one or more demodulation reference signal, DMRS, ports associated with the plurality of PDSCHs are quasi co-located with respect to Doppler shift, a determination that the plurality of PDSCHs are scheduled to completely overlap in a time domain, a determination that the plurality of PDSCHs belong to the same component carrier or the same bandwidth part of the component carrier, or a combination thereof. <EOS>
