User Equipment-Initiated Phase Tracking for Fifth Generation New Radio

A user equipment (UE) comprising:

• a radio frequency (RF) transceiver;
• and
• a processor and memory system to implement a phase tracking manager application configured to:
• determine a current operating condition related to a wireless communication link between the UE and a base station;
• based on the determination of the current operating condition, select a configuration for one or more air interface resources selected to transmit a phase-tracking reference signal (PT-RS);
• transmit a request to the base station, using the RF transceiver, the request including the selected configuration for the one or more air interface resources;
• and
• receive, via the wireless communication link and using the RF transceiver, at least some of the one or more air interface resources in the selected configuration, each of the at least some of the one or more air interface resources including the PT-RS.

A system comprising:

• a gNode B (gNB);
• and
• a user equipment (UE) configured to:
• determine a current operating condition related to a wireless communication link between the UE and the gNB;
• based on the determination of the current operating condition, select a configuration for one or more resource elements selected to transmit a phase-tracking reference signal (PT-RS);
• transmit a request to the gNB, the request including the selected configuration for the one or more resource elements;
• and
• receive, from the gNB and via the wireless communication link, at least some of the one or more resource elements in the selected configuration, each of the at least some of the one or more air interface resources element including the PT-RS.
