Abstract: A method for using a joint decoding engine in a wireless device is disclosed. A first symbol stream and a second symbol stream in a received multiple input multiple output (MIMO) signal is determined. A scaled channel estimate for a wireless transmission channel and a scaled noise covariance of the MIMO signal are also determined. The scaled channel estimate and the first symbol stream are whitened. Max log maximum a posteriori (MLM) processing is performed on the whitened first symbol stream to produce a first data stream. The first data stream may be de-rate matched and decoded to produce a decoded first data stream.

Abstract: In the processing of a data transmission received on wireless data channel HS-DSCH during HS-SCCH-less (HSL) operation according to 3GPP TS 25.214 V7.7.0, a situation is identified wherein redundancy version information corresponding to the received data transmission cannot be obtained from wireless control channel HS-SCCH. The redundancy version information is normally indicative of an HSL redundancy version that specifies derate matching for the received data transmission. In response to identification of the situation, derate matching is applied to the received data transmission according to an HSL redundancy version other than the HSL redundancy version that is specified by HSL for derate matching in the situation.
