Abstract
A wireless communication network (100) employs a method and apparatus for reliably communicating information packets in the network. A first wireless device (101) in the network transmits an information packet to a second wireless device (e.g., 102) in the network over a first wireless communication channel (403, 404). The first device then determines whether the information packet was successfully received (e.g., received without errors) by the second device. If the information packet was not successfully received, the first device retransmits the information packet to the second device over a second wireless communication channel (405, 406). In addition, and preferably substantially contemporaneous with retransmission of the first information packet, the first device transmits a second information packet to the second device over the first channel in an effort to communicate an information sequence to the second device without delays typically associated with use of a reliable protocol.
