A UE scheduled for one PDSCH with DMRS ports in two or more DMRS CDM groups that are associated with two TCI states may be configured for PT-RS using two PT-RS ports. Therefore, rather than limiting PT-RS to a single port, the PT-RS may be transmitted to the UE using two PT-RS ports. The apparatus transmits a capability indication for more than one PT-RS port for receiving a downlink shared channel based on a first TCI and a second TCI. The apparatus receives a configuration for a maximum number of downlink PT-RS ports from a base station."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Phase tracking reference signal for multi-transmit/receive points","description":"A phase tracking reference signal (PT-RS) may be transmitted to enable a receiver to correct phase noise in wireless communication.
