Boosted noncoherent modulation

A method for wireless communications at a receiving device, comprising:

• receiving a modulated signal from a transmitting device on a set of subcarriers;
• de-mapping the modulated signal to a first subset of subcarriers and a second subset of subcarriers using a boosting factor applied to the set of subcarriers, wherein the boosting factor is based at least in part on a repetition factor associated with the set of subcarriers;
• and
• decoding the first subset of subcarriers to a first set of data bits and the second subset of subcarriers to a second set of data bits, wherein at least one or both of the first set of data bits and the second set of data bits have been rate matched based at least in part on the boosting factor.

An apparatus for wireless communications, comprising:

• a processor, and
• a memory coupled with the processor, wherein the memory comprises instructions executable by the processor to cause the apparatus to:
• encode a set of data bits to transmit to a receiving device on a set of subcarriers using a boosting factor applied to the set of subcarriers, wherein the boosting factor is based at least in part on a repetition factor associated with the set of subcarriers;
• rate matching the set of encoded data bits based at least in part on the boosting factor;
• map the set of encoded data bits to a resource block comprising a first subset of subcarriers corresponding to the set of encoded data bits and a second subset of subcarriers corresponding to a set of null bits;
• generate a signal comprising the set of encoded data bits based at least in part on the mapping;
• and
• transmit the generated signal to the receiving device.
