Frame structure suitable for terahertz-band-based communication environment

A method performed by a terminal of a communication system, the method comprising:

• identifying a subcarrier spacing for a communication between a base station and the terminal;
• receiving, from the base station, a signal including information indicating at least one of whether an additional symbol is allocated or a number of additional symbols, wherein the number of additional symbols is based on the subcarrier spacing;
• receiving, from the base station, data allocation information for mapped data;
• and
• receiving, from the base station, the mapped data on the additional symbol based on the data allocation information,
• wherein the additional symbol is allocated to a predetermined part of a first slot for every 0.5 ms boundary, wherein in case that the subcarrier spacing is 15×2n kHz and n is 8, the number of the additional symbols is at most 1,
• wherein in case that the subcarrier spacing is 15×2n kHz and n is 9, the number of the additional symbols is at most 3, and
• wherein in case that the subcarrier spacing is 15×2n kHz and n is 10, the number of the additional symbols is at most 7.

A base station of a communication system, the base station comprising:

• a transceiver;
• and
• a controller configured to:
• identify a subcarrier spacing for a communication between the base station and a terminal,
• transmit, to the terminal, a signal including information indicating at least one of whether an additional symbol is allocated or a number of additional symbols, wherein the number of additional symbols is based on the subcarrier spacing,
• generate data allocation information for mapping data based on the allocation of the additional symbol, and
• transmit, to the terminal, the data allocation information and the mapped data,
• wherein the additional symbol is allocated to a predetermined part of a first slot for every 0.5 ms boundary,
• wherein in case that the subcarrier spacing is 15×2n kHz and n is 8, the number of the additional symbols is at most 1,
• wherein in case that the subcarrier spacing is 15×2n kHz and n is 9, the number of the additional symbols is at most 3, and
• wherein in case that the subcarrier spacing is 15×2n kHz and n is 10, the number of the additional symbols is at most 7.
