Abstract: Provided is a radio communication terminal which is capable of measuring quality in communication with a handover destination with high accuracy. The radio communication terminal is capable of communicating with a base station or a relay node, and includes: a receiver which receives control information including information relating to measurement of measuring quality of a neighbor cell; an extractor which extracts information on a subframe where the measurement should be performed, which is a subframe where only transmission of a signal from the relay node connected to the base station is performed, from the information relating to the measurement; a measurement section which performs the measurement, on a subframe basis, based on the extracted information on the subframe where the measurement should be performed; and a transmitter which transmits a result of the measurement to the base station or the relay node.

Abstract: A communication apparatus includes a receiver, a combiner, and a transformer. The receiver receives signals mapped on plural frequency bands. A size of at least one of the frequency bands is a multiple of a product of two or more powers of prime numbers, which are integer numbers greater than 1 and are different from each other. An exponent for at least one of the prime numbers is an integer greater than 1. The combiner combines the received signals into a combined signal. The transformer transforms the combined signal in a frequency domain into a symbol sequence in a time domain with an inverse discrete Fourier transform (IDFT) having a size that is a product of powers of plural values. The values are integer numbers greater than 1 and are different from each other. An exponent for at least one of the values is an integer greater than 1.

Abstract: A communication apparatus includes a Discrete Fourier Transform (DFT) transformer, a mapper, and a signal generator. The DFT transformer transforms a symbol in a time domain into a signal in a frequency domain with a DFT size that is a product of powers of a plurality of values, which are integer numbers greater than 1 and are different from each other. The mapper maps the signal in the frequency domain on a plurality of frequency bands, wherein a vector length corresponding to a size of each of the plurality of frequency bands is a product of two or more powers of prime numbers or a multiple of such product, and wherein the vector length is a number of subcarriers allocated to a corresponding one of the plurality of frequency bands. The signal generator generates a single carrier-frequency division multiple access (SC-FDMA) signal in the time domain from the mapped signal.
