Abstract:
1. A radio transmitting apparatus comprising: a hopping pattern setting section configured to set a hopping pattern by varying a switching cycle to switch a sequence number of a code sequence to be used as a reference signal or a number of time slots to use for looping back to the sequence number of the code sequence in accordance with a transmission bandwidth or a sequence length of the reference signal; a sequence generator configured to generate the code sequence based on the set hopping pattern; and a transmitter configured to transmit the generated code sequence, wherein: the hopping pattern setting section sets the hopping pattern such that the switching cycle to switch the sequence number of the code sequence becomes shorter when the transmission bandwidth becomes narrower or when the sequence length becomes shorter, and the switching cycle to switch the sequence number of the code sequence becomes longer when the transmission bandwidth becomes wider or the sequence length becomes longer.
