Classification: CPC H | IPC H

Claim 7:
8. A user equipment for reporting Doppler shift to a transmission-reception point (TRP), the user equipment comprising:
a transceiver configured to transmit and receive signals with a first TRP and a second TRP; and
one or more processors configured to:
receive a reference signal from at least one the first TRP and the second TRP;
estimate a Doppler shift associated with each of the first TRP and the second TRP based on the received reference signal;
generate a reporting signal based on the estimated Doppler shift; and
transmit the reporting signal to a gNB via the transceiver,
wherein the reporting signal includes an absolute first Doppler shift associated with the first TRP, and a difference value corresponding to a difference between the absolute first Doppler shift and an second Doppler shift associated with the second TRP, together with the signs of the absolute first Doppler shift and the absolute second Doppler shift.
