Abstract:
In an adaptive hybrid automatic repeat request coding system, a method of transmitting a plurality of data packets, said method comprising the steps of:receiving a first batch of data from a data source, said first batch of data containing therein received data and error correction data, the amount of error correction data in said first batch varying between at least a first and a second mode, the amount of error correction data in a given batch in said first mode exceeding the amount of error correction data in said given batch in said second mode; incrementing a packet number by an increment factor, said increment factor being associated with a ratio of (1) the difference between a packet data capacity number and the amount of error correction data in said second mode, and (2) the difference between said packet data capacity number and the amount of error correction data in said first mode; assembling at least a portion of said received data, error correction data corresponding to said at least a portion of said received data, and said packet number into a given packet; and transmitting said given packet to a receiver.
