Abstract :
The D-TxAA scheme was adopted by 3GPP as standard for HSDPA MIMO. The link adaptation in HSDPA is performed on base of channel quality indicator (CQI) reports, which are the quantized estimates of the received signal SINR. However, the method of the SINR estimation used in non-MIMO HSDPA is not possible to use directly for D-TxAA scheme. In this paper the method of SINR calculation for D-TxAA scheme is proposed.
