Classification: CPC H | IPC H

Claim 0:
1. A user equipment comprising:
a transceiver configured to transmit and receive signals between a first transmission-reception point (TRP) and a second TRP: and
one or more processors configured to:
receive reference signals from a plurality of TRPs via the transceiver, each reference signal including an identifier;
determine an originating TRP as being one of the first TRP or the second TRP based on the identifier;
calculate Doppler shifts associated with each of the first TRP and the second TRP based on the determining;
coherently combine the plurality of reference signals based on the calculating; and
transmit an uplink signal via the transceiver to at least one of the first TRP or the second TRP based on the combined plurality of reference signals; and
generate and transmit a reporting signal based on the calculated Doppler shifts, the reporting signal including 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 absolute second Doppler shift associated with the second TRP, together with the signs of the absolute first Doppler shift and the absolute second Doppler shift.
