Abstract
An operation method of a first communication node includes generating a plurality of modulation symbols for information bits; determining a symbol mapping pattern based on a number Nof antennas of the first communication node, a number Nof spatial layers multiplexed in a same frequency resource, and a number Nof modulation symbols belonging to one space-frequency grid; mapping the plurality of modulation symbols to a space-frequency domain based on the symbol mapping pattern; and transmitting the plurality of modulation symbols mapped to the space-frequency domain to a second communication node using the antennas.
