Patent ID: 7839776

Claim:
A method, comprising: accessing, at a receiver, first encoded information indicative of a data rate for transmission of a sub-packet and a first sub-packet identifier associated with the sub-packet; accessing, at the receiver, second encoded information indicative of the data rate and a second sub-packet identifier associated with the sub-packet, the second encoded information having been received subsequent to the first encoded information in response to a request to re-transmit the sub-packet; separating, at the receiver, the second encoded information into data rate information indicative of the data rate and sub-packet identifier information indicative of the second sub-packet identifier; forming modified second encoded information by encoding a combination of: the data rate information separated from the second encoded information, and information indicative of the first sub-packet identifier; forming, at the receiver, third encoded information based on the first encoded information and the modified second encoded information; and decoding, at the receiver, the third encoded information to determine the data rate used to decode the sub-packet.
