Abstract
A method and apparatus for transmitting a signal whereby it is determined if a Bandwidth Expansion Factor (BEF) Q is an integer, the BEF being determined as N/M according to a number N of subcarriers of a system band and a number M of subcarriers of an allocated band, an input signal to be transmitted Q times in a time domain when the Q is an integer is expanded, a Single Carrier Frequency Division Multiplexing Access (SC-FDMA) signal is generated, and the SC-FDMA signal is transmitted.
Claims22
A method for transmitting a signal of a transmitter in a Single Carrier-Frequency Division Multiplexing Access (SC-FDMA) communication system, the method comprising:
- determining if a Bandwidth Expansion Factor (BEF) Q is an integer, the BEF being determined as N/M according to a number N of subcarriers of a system band and a number M of subcarriers of an allocated band;
- expanding Q times, in a time domain, an input signal to be transmitted, when the Q is the integer;
- generating an SC-FDMA signal;
- and
- transmitting the SC-FDMA signal.
An apparatus for transmitting a signal in a Single Carrier-Frequency Division Multiplexing Access (SC-FDMA) communication system, the apparatus comprising:
- a controller for determining if a Bandwidth Expansion Factor (BEF) Q is an integer, the BEF being determined as N/M according to a number N of subcarriers of a system band and a number NM of subcarriers of an allocated band;
- and
- a multiplier for generating an SC-FDMA signal through use of an input signal to be transmitted, which is expanded Q times in a time domain, when the Q is the integer.
