Pilot signal transmission method and radio communication apparatus |
摘要 |
In a radio communication system, transmission of CAZAC sequences as the pilot signal sequences by using code division multiplexing as at least one of user multiplexing schemes, is done by dividing a system band as a frequency band usable in the system into frequency blocks B1 and B2 having bandwidths W1 and W2, generating the pilot signals of the frequency blocks B1 and B2 with a single carrier, using the pilot signal sequences having sequence lengths L1 and L2 corresponding to frequency blocks B1 and B2 respectively; and, transmitting the generated pilot signals as the pilot signals corresponding individual users, with multicarriers using an arbitrary number of frequency blocks among the plural frequency blocks. |

1. A user equipment comprising:
a reference signal generator configured to generate a first reference signal including a sequence having a first sequence length corresponding to a first bandwidth assigned for data transmission and a second reference signal including a sequence having a second sequence length corresponding to a second bandwidth assigned for data transmission; and a transmitter configured to transmit, in a radio communication system, from the user equipment, the first reference signal using the first bandwidth and the second reference signal using the second bandwidth. |
