    摘要: In a radio communication method non-contiguously using a frequency, notification information is reduced, while suppressing an effect on performance. In a communication apparatus which switches between a communication method contiguously using a frequency and a communication method non-contiguously using the frequency, sets a parameter corresponding to each communication method, and performs radio communication, the communication apparatus sets a same parameter to an entire frequency band in the communication method contiguously using the frequency, while dividing a frequency band into a plurality of frequency bands and setting a different parameter for each divided frequency band in the communication method non-contiguously using the frequency. The communication method contiguously using the frequency and the communication method non-contiguously using the frequency mutually have different PAPR (Peak to Average Power Ratio) characteristics.
