ABSTRACT:
In the channel quality information (CQI) coding method of the present invention, first basis sequences for generating sub-codes of 32 bits are created, and second basis sequences for generating codewords of 20 bits are created using the first basis sequences, the second basis sequence maximizing system throughput such that five information bits are coded into CQI code using the second basis sequences. Also, since HSDPA system has been designed in order to increase the system throughput, the CQI coding method of the present invention, which shows the best system throughput in the simulation, can be the optimum CQI coding scheme for HS-DPCCH.
