Latest Patents

One of his latest patents is titled "Apparatus and method for scrambling a packet data channel and a packet data control channel in a mobile communication system for high-speed packet transmission." This invention involves a base station PDCCH (Packet Data Control Channel) apparatus designed to scramble transmission packet data. It prevents unauthorized terminals from recognizing the transmission packet data. The apparatus includes a packet data channel device for transmitting packet data and a packet data control channel device for sending control information necessary for demodulation. An encoder encodes the control information, generating a coded control information stream. A scrambler then uses unique information known only to the terminal and the base station to scramble this stream.

Another notable patent is "Apparatus and method for communicating packet data control channel in a mobile communication system." This invention pertains to a base station transmission apparatus that transmits MAC (Medium Access Control) ID information. It indicates which terminal is to receive the transmission packet data and includes length information about the data. The apparatus features an encoder that generates coded symbols from the MAC ID information. It also includes a Walsh cover section that applies a Walsh code based on the length information, along with a Walsh spreader for further processing the symbols.
