Aperiodic and cross component carrier positioning reference signals

An apparatus for wireless communications by a user equipment (UE), comprising:

• one or more transceivers;
• one or more memory;
• and
• one or more processors electronically coupled to the one or more memory and the one or more transceivers, the one or more processors configured to:
• transmit a capability indicator that indicates the UE is capable of maintaining phase coherence for a positioning reference signal that spans multiple component carriers;
• receive control signaling indicating a plurality of component carriers on which the positioning reference signal is phase coherent based at least in part on the capability indicator;
• generate a timing measurement for the positioning reference signal that spans the plurality of component carriers based at least in part on the control signaling;
• and
• transmit a measurement report that indicates the timing measurement.

An apparatus for wireless communications by a transmission/reception point, comprising:

• one or more transceivers;
• one or more memory;
• and
• one or more processors electronically coupled to the one or more memory and the one or more transceivers, the one or more processors configured to:
• transmit a dynamic trigger that indicates that a user equipment (UE) is to monitor for a downlink positioning reference signal from a transmission/reception point;
• and
• receive a measurement report that indicates a timing measurement for the downlink positioning reference signal.
