Aperiodic and cross component carrier positioning reference signals

Abstract:

Methods, systems, and devices for wireless communications are described. The described techniques relate to improved methods, systems, devices, and apparatuses that support aperiodic and cross component carrier positioning reference signals (PRSs). Generally, the described techniques provide for receiving a dynamic trigger indicating that a user equipment (UE) is to monitor for one or more downlink PRSs. The UE may generate a timing measurement for the downlink PRSs, and may transmit a measurement report that indicates the timing measurement to a transmission/reception point. A UE may also transmit a capability indicator, indicating that the UE is capable of maintaining phase coherence for a PRS that spans multiple component carriers, receive control signaling that indicates multiple component carries on which the PRS is phase coherent, generate a timing measurement for the PRS based on the control signaling, and transmit a measurement report that indicates the timing measurement to the transmission/reception point.
