Transmitting signals with delays

A user equipment (UE), comprising:

• at least one memory;
• and
• at least one processor coupled with the at least one memory and configured to cause the UE to:
• determine a first transmit signal based on a set of modulation symbols;
• determine a second transmit signal based on the first transmit signal, wherein the second transmit signal is a delayed copy of the first transmit signal that is delayed by a delay, and the delay is less than a maximum value;
• transmit, to a network device, the first transmit signal from a first antenna of the UE;
• transmit, to the network device, the second transmit signal from a second antenna of the UE;
• and
• transmit information indicating the delay to the network device.

An apparatus for performing a network function, the apparatus comprising:

• at least one memory;
• and
• at least one processor coupled with the at least one memory and configured to cause the apparatus to:
• indicate, to a user equipment (UE), to transmit a set of modulation symbols;
• receive, from the UE, a receive signal comprising a first signal based on the set of modulation symbols, and a second signal from a second antenna of the user equipment, wherein the second signal is based on the first signal, and the second signal is a delayed copy of the first signal that is delayed by a delay, and the delay is less than a maximum value;
• receive, from the UE, information indicating the delay;
• and
• demodulate the received signal to determine the set of modulation symbols.

A method performed by a network function, the method comprising:

• indicating, to a user equipment (UE), to transmit a set of modulation symbols;
• receiving, from the UE, a receive signal comprising a first signal based on the set of modulation symbols, and a second signal, wherein the second signal is based on the first signal, and the second signal is a delayed copy of the first signal that is delayed by a delay, and the delay is less than a maximum value;
• receiving, from the UE, information indicating the delay;
• and
• demodulating the received signal to determine the set of modulation symbols.
