CQI coding method using various basis sequences

The present invention is a channel quality indicator for transmitting to inform a channel status of the forward connection (High Speed ​​Downlink Packet Access) HSDPA: transmitting to inform a channel status in a mobile communication system according to the (CQI Channel Quality Indicator) coding method, channel quality indicator: in the coding method of the (CQI channel quality indicator) code, comprising: making a base sequence to that encoding a predetermined input information bits into a code word of 32 bit length; The step of dropping the bits of a particular sequence from the code word of 32 bit length of the base sequence; There a wide range of CQI encoding method using a base sequence comprising the steps of creating a base sequence of 20-bit length of the bits in a particular order of the bits is decreased by repeating a predetermined number of code words to provide.
