generator 406 converts the mcs level information and the logical indicator in a format suitable for a radio channel for example if a dpcch transmits the control information the control information generator 406 converts the control information in the transmit format of the dpcch the channel encoder 407 channel encodes the control information received from the control information generator 406 by a channel encoding scheme for example a convolutional coding scheme or a turbo coding scheme the control data transmitter 408 performs modulation and channelization on the channel encoded control information and transmits the resulting control information to the ue on the radio link 0057 fig5 is a block diagram of a receiver for receiving the ovsf code information in the hsdpa communication system according to the embodiment of the present invention in fig5 the receiver receives user data on the hs dsch and control information on a downlink control channel in the ue in correspondence to the channel encoding scheme used in the transmitter the receiver is comprised of a control data receiver 501 a channel decoder 502 a control information interpreter 503 a user data receiver 504 a turbo decoder 505 a reception buffer 506 and an ovsf code information table 507 upon receipt of data on a radio link the data is fed to the control data receiver 501 and.
