Abstract:
1. A method of transmitting at least one subpacket of an encoder packet in a communication system, the method comprising: setting a plurality of combinations of transmission variables for transmitting a subpacket of an encoder packet; defining a plurality of predetermined modulation order product code rates (MPRs), each predetermined MPR corresponds to each combination of numbers of available encoder packet bits and of numbers of available slots; selecting an arbitrary combination of transmission variables from the plurality of combinations of transmission variables based on a number of currently available Walsh codes; determining an arbitrary MPR based on a number of available encoder packet bits, a number of available slots, and the number of currently available Walsh codes, wherein the arbitrary MPR corresponds to the selected arbitrary combination of transmission variables; selecting as a final MPR one of the plurality of predetermined MPRs, which corresponds to the number of available encoder packet bits and the number of available slots, that is greater than or equal to the arbitrary MPR and has a smallest difference; calculating a final number of Walsh codes based on the number of available encoder packet bits, the number of available slots, and the selected final MPR; determining available combinations of transmission variables from the plurality of combinations of transmission variables based on the numbers of available encoder packet bits, the numbers of available slots, and the final number of Walsh codes; and transmitting the subpacket of the encoder packet using one of the determined combination of transmission variables.
