Techniques for pre- and decoding a multicarrier signal based on a mapping function with respect to inband and out-of-band subcarriers

A reception device, comprising:

• a receiver configured to receive a multicarrier signal that is based on a combination of data symbols and reference symbols, wherein the multicarrier signal comprises a first plurality of inband subcarriers and a second plurality of out-of band (OOB) subcarriers;
• and
• a processor configured to decode the multicarrier signal based on a mapping function with respect to the first plurality of inband subcarriers and the second plurality of OOB subcarriers, wherein the mapping function is configured to mitigate the OOB subcarriers,
• wherein the mapping function is based on a frequency offset (FO) between an oscillator of a transmitter transmitting the multicarrier signal and an oscillator of the receiver receiving the multicarrier signal, and
• wherein the transmitter transmitting the multicarrier signal precodes the multicarrier signal based on the mapping function prior to transmitting the multicarrier signal to the receiver.

A transmission method performed by a transmission device, comprising:

• generating, by a processor of the transmission device, a multicarrier signal based on a combination of data symbols and reference symbols, wherein the multicarrier signal comprises a first plurality of inband subcarriers and a second plurality of out-of band (OOB) subcarriers;
• and
• precoding, by the processor, the multicarrier signal based on a mapping function with respect to the first plurality of inband subcarriers and the second plurality of OOB subcarriers, wherein the mapping function is configured to mitigate the second plurality of OOB subcarriers, and
• wherein the mapping function is based on a frequency offset (FO) between an oscillator of a transmitter of the transmission device transmitting the precoded multicarrier signal and an oscillator of a receiver receiving the precoded multicarrier signal.
