In a method for determining channel quality information in a high speed packet access communication system with closed loop transmit diversity, power and variance related to a common pilot channel (CPICH) are determined for a rake receiver to obtain a closed loop transmit gain adjustment and to determine the CPICH signal-to-noise ratio. Thereafter, a high speed downlink shared channel (HS-DSCH) signal-to-noise ratio is determined from the CPICH signal-to-noise ratio and is mapped to derive channel quality information.
