System and method for DL transmission with low peak-to-average-power (PAPR)

A method of wireless communication in a frequency band, the method comprising:

• precoding, in a frequency domain, a plurality of physical channel signals according to predetermined codes with a code length;
• multiplexing the precoded plurality of physical channel signals;
• mapping the multiplexed precoded plurality of physical channel signals to subcarriers in the frequency band;
• generating a time domain waveform based on the mapped multiplexed precoded plurality of physical channel signals;
• and
• transmitting the time domain waveform to a user equipment (UE),
• wherein the code length is selected based on a length of an entire signal of the multiplexed plurality of physical channel signals.

A non-transitory computer-readable media comprising instructions to cause an electronic device, upon execution of the instructions by one or more processors of the electronic device, to perform operations, the operations comprising:

• precoding, in a frequency domain, a plurality of physical channel signals according to predetermined codes with a code length;
• multiplexing the precoded plurality of physical channel signals;
• mapping the multiplexed precoded plurality of physical channel signals to subcarriers in the frequency band;
• generating a time domain waveform based on the mapped multiplexed precoded plurality of physical channel signals;
• and
• transmitting the time domain waveform to a user equipment (UE),
• wherein the code length is selected based on a length of an entire signal of the multiplexed plurality of physical channel signals.
