<p>A communication device employs a method and apparatus for transmitting and receiving information packets using multiple layers of error detection (404-406). A sending communication device constructs an information packet to include user information divided into multiple data blocks, a primary error detection code for each data block, and at least a portion of a secondary protection code (407). The secondary protection code provides error protection for the entire information packet. The secondary protection code is selected such that it can be incrementally determined by a receiving device as data blocks are received and accepted by the receiving device, regardless of order of reception of the data blocks. Since the secondary protection code is incrementally determined, processor utilization is better regulated and delays associated with sending acknowledgments are minimized.</p> |
