Abstract

Systems and methodologies are described that facilitate mitigating effects of mismatch errors related to incorrectly decoded acknowledgments indicative of successfully decoded data packets in a wireless network environment. Misinterpretation of a cumulative acknowledgment related to a number of successfully decoded data packets can be identified, and data packet transmission mismatch errors caused thereby can be evaluated to determine an optimal manner in which to decode and acknowledge remaining data packets to alleviate mismatch and restore synchronization between a transmitter of the data packets and a receiver thereof.

Description

[0001] Cross References to Related Applications [0002] Pursuant to 35 U.S.C. §119(e), this application claims provisional patent application Ser. priority, and priority to Provisional Patent Application No. 60 / 688,091, filed June 6, 2005, entitled "Mitigating ACK / NACK errors in MIMO / SIC / HARQ," which are hereby incorporated by reference in their entirety. technical field [0003] The following description relates to wireless communications in general and, in particular, how to reduce acknowledgment signal interpretation errors and the adverse effects associated therewith to improve throughput in a wireless network environment. Background technique [0004] Wireless networking systems have become the primary means by which most people around the world communicate. Wireless communication devices have become smaller and more powerful to meet consumer demands for increased portability and convenience. The improvement of the processing capability of mobile devices such as cell...
