A mobile communication unit which can perform a high-bit rate information transmission by allocating a plurality of channel numbers to a user who carries out a high-bit rate communication. The mobile communication unit includes a set of units at the transmitter side 21 and a set of units at the receiver side 22, to carry out communications by allocating spread codes to channels within the same cell. A plurality of channel numbers are allocated to one user. The transmitter side units include the separating unit 23 for separating the user information, the spread modulator 30 for spread processing the separated information by using the spread codes corresponding to the respective channel numbers, and the combining unit 31 for combining the diffused information and outputting the combined information to the receiver side unit. The receiver side units include the despreader 32 for despread the diffused information by using the spread codes of the respective channel numbers allocated to the user, and the multiplexing unit 33 for combining the despreaded information of the plurality of channels. Thus, a high-bit rate transmission service is provided.
