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.
