ABSTRACT:
Systems and methodologies are described that facilitate reliably receiving a sequence of data packets in a wireless communications environment. In particular, mechanisms are provided that enhance hybrid automatic repeat request protocols through validation of acknowledgment message detection by re-decoding. A transmitter sends a data packet from a sequence of packets in one or more data transmissions. A receiver acknowledges the data packet upon obtaining sufficient transmissions to decode the packet. The receiver re-decodes a successive data transmission in combination with previously received transmissions to validate if the transmitter detected the acknowledgment.
