Cyclic delay and doppler shift

A method of wireless communication performed by a transmitter, comprising:

• applying at least one of an amount of delay or an amount of Doppler shift to a signal transmission including a first signal for transmission from a first antenna and a second signal for transmission from a second antenna, wherein the second signal is shifted, relative to the first signal, in a delay-Doppler domain, by the at least one of the amount of delay or the amount of Doppler shift;
• and
• outputting, in a time-frequency domain, the first signal from the first antenna and the second signal from a second antenna.

A method of wireless communication performed by an apparatus of a user equipment (UE), comprising:

• receiving an indication of at least one of an amount of delay or an amount of Doppler shift, in a delay-Doppler domain, of a signal transmission;
• and
• receiving, in a time-frequency domain, a first signal from a first antenna and a second signal from a second antenna, wherein the second signal is shifted in the delay-Doppler domain, relative to the first signal, by the at least one of the amount of delay or the amount of Doppler shift.
