Frequency modulated continuous wave signal-based positioning in new radio

A method of wireless positioning performed by a network entity, the method comprising:

• identifying a set of transmission/reception points (TRPs) for transmitting frequency modulated continuous wave (FMCW) signals for a positioning measurement, wherein a FMCW signal comprises a signal that starts at a start frequency and changes its frequency over time until it reaches an end frequency, at which time the signal stops, the set comprising at least a first TRP and a second TRP;
• receiving, from a user equipment (UE) that sends and receives orthogonal frequency division multiplexing (OFDM) signals, information identifying a capability of the UE to process FMCW signals;
• and
• sending, to the UE, information identifying the set of TRPs and identifying FMCW signals to be transmitted by each TRP in the set of TRPs.

A user equipment (UE) that sends and receives orthogonal frequency division multiplexing (OFDM) signals, comprising:

• a memory;
• at least one transceiver;
• and
• at least one processor communicatively coupled to the memory and the at least one transceiver, the at least one processor configured to:
• send, via the at least one transceiver, to a network entity, information identifying a capability of the UE to process frequency modulated continuous wave (FMCW) signals, wherein a FMCW signal comprises a signal that starts at a start frequency and changes its frequency over time until it reaches an end frequency, at which time the signal stops;
• receive, via the at least one transceiver, from a network entity, information identifying a set of transmission/reception points (TRPs) for transmitting FMCW signals for a positioning measurement and identifying FMCW signals to be transmitted by each TRP in the set of TRPs, the set comprising at least a first TRP and a second TRP;
• measure a first FMCW signal that was transmitted by the first TRP to determine a first frequency of arrival;
• measure a second FMCW signal that was transmitted by the second TRP to determine a second frequency of arrival;
• and
• determine a location of the UE based on a frequency difference between the first frequency of arrival and the second frequency of arrival.
