1. An integrated circuit to control a process, the process comprising: transmitting, to a mobile station, control information related to a sequence in one of multiple groups, into which sequences for each of multiple sequence lengths having at least two different lengths are divided; and receiving a reference signal, which is generated using the sequence in one of the multiple groups based on the control information and which is transmitted from the mobile station, wherein a first respective predefined number of sequence(s) contained in a first group of the multiple groups into which sequences having a first sequence length are divided is less than a second respective predefined number of sequences contained in a second group of the multiple groups into which sequences having a second sequence length are divided where the first sequence length is less than a threshold value and the second sequence length is greater than or equal to the threshold value.
