Aspects of the disclosure are directed to a method, apparatus, and computer software for wireless communication. In various examples, a method of wireless communication performed by a user equipment (UE) includes measuring channel quality over a measurement period associated with a voice call corresponding to a first subscription supported by the user equipment, determining whether the channel quality is sufficient to enable an adaptive multi-rate (AMR) decoder to ignore one or more bursts of a plurality of bursts carrying a block of data received at the user equipment, and causing the adaptive multi-rate decoder to decode the block of data without the one or more bursts when the channel quality is determined to be sufficient to enable the adaptive multi-rate decoder to ignore the one or more bursts. The channel quality may be measured by measuring a bit error rate for a transmission on a slow associated control channel (SACCH).
