Patent ID: 7227854

Claim:
A method for transmitting, by a user equipment (UE) located in a soft handover region, channel quality indicator (CQI) information bits for informing a Node B of a quality of a downlink channel through a CQI field and a high speed pilot (HS-Pilot) field constituting a subframe of an uplink secondary dedicated physical control channel (DPCCH) in a code division multiple access (CDMA) communication system, the method comprising the steps of: outputting a codeword of length 20 by coding the CQI information bits with a code of length 20 , which is used when a high speed downlink packet access (HSDPA) service is not supported; and permuting 15 coded bits that are coded by the code as a code of length 15 , which is used when the HSDPA service is supported, among the 20 coded bits constituting the codeword, thereby locating the 15 coded bits in the CQI field, and permuting the 5 remaining coded bits to be located in the HS-Pilot field.
