Apparatus and method for symbol mapping in wireless communication system using multi tone frequency quadrature amplitude modulation

A method of operating a terminal in a wireless communication system, the method comprising:

• identifying channel quality information of a first region of a signal;
• identifying non-Gaussian information of a second region of the signal;
• and
• transmitting, to a base station, the channel quality information of the first region and the non-Gaussian information of the second region,
• wherein the non-Gaussian information indicates whether the base station uses a modulation scheme related to a non-Gaussian distribution or not.

A base station apparatus in a wireless communication system, the base station apparatus comprising:

• a Radio Frequency (RF) processor configured to transmit data;
• and a modem configured to:
• identify a modulation scheme based on a type of resource blocks, wherein the resource blocks are used for data to be transmitted to a terminal, and
• modulate the data according to the identified modulation scheme,
• wherein, if the type of the resource blocks is continuous resource block (CRB), the modulation scheme is identified as a first modulation scheme, and
• wherein, if the type of the resource blocks is distributed resource block (DRB), the modulation scheme is identified as a second modulation scheme.

A terminal apparatus comprising:

• a Radio Frequency (RF) processor configured to receive a signal from a base station;
• and
• a modem configured to:
• identify channel quality information of a first region of the signal, and
• identify non-Gaussian information of a second region of the signal via the RF processor,
• wherein the non-Gaussian information indicates whether the base station uses a modulation scheme related to a non-Gaussian distribution or not.
