In one aspect, a UE is configured to receive a data or voice frame from a base station. The UE selects one or more quality metrics for determining decoding boundary of the received frame and computes the selected one or more quality metrics.

If the early decoding of the frame was successful, the UE may terminate reception of the frame. If the early decoding of the frame was unsuccessful, the UE may adjust the decoding boundary and decodes the frame at the adjusted boundary.
