Abstract
A base station PDCCH (Packet Data Control Channel) apparatus for scrambling transmission packet data to prevent other terminals from recognizing the transmission packet data in a base station including a packet data channel device for transmitting packet data to a terminal and a packet data control channel device for transmitting control information needed for demodulation of the packet data to the terminal. In the apparatus, an encoder encodes the control information and generates a coded control information stream comprised of a stream of a plurality of bits. A scrambler generates a scrambling sequence using unique information known to only the terminal and the base station, and scrambles the coded control information stream with the scrambling sequence.
