Patent ID: 8503389

Claim:
A transmitting apparatus which is capable of performing transmission at both a first frequency and a second frequency, the transmitting apparatus comprising: a generator which generates a signal to be used by a receiving apparatus for measuring communication quality; and a transmitter which transmits the signal in a first frequency band in a given portion of a first time period, and transmits the signal in a second frequency band in a given portion of a second time period coming after the first time period, the first frequency band not including the first frequency, the second frequency band not including the second frequency, wherein: each of the first time period and the second time period includes a first sub-time period including the given portion used for transmission of the signal and a second sub-time period not including the given portion for transmission of the signal; and when performing both the signal transmission and data transmission in the first time period, the transmitter performs the data transmission at the second frequency in the first sub-time period of the first time period except for the given portion used for the signal transmission, and performs the data transmission at the first frequency in the second sub-time period of the first time period, and when performing both the signal transmission and the data transmission in the second time period, the transmitter performs the data transmission at the first frequency in the first sub-time period of the second time period except for the given portion used for the signal transmission, and performs the data transmission at the second frequency in the second sub-time period of the second time period.
