Abstract
A base station for transmitting data in an OFDM system is provided. The base station is configured to convert data or a signal into a wireless band and transmit the converted data or signal to a terminal, down-convert a signal and output the down-converted signal, and generate a message for requesting terminal capability information for a sub-carrier spacing and transmit the message to the terminal accessing the base station, generate information on sub-bands of groups available to the terminal in response to receiving a terminal capability response message from the terminal and transmit the information on the sub-bands of groups available to the terminal, allocate a resource by selecting sub-bands of one group of the sub-bands of the groups available to the terminal in response to receiving a scheduling request message from the terminal and generate and transmit a resource allocation message, and transmit the data using the allocated resource.
