1. A method for decoding a message transmitted in a wireless communication system supporting packet data transmission, wherein a packet is divided into a number of subpackets, the method comprising:
- determining a set of hypotheses for decoding the message, wherein the set of hypotheses includes a plurality of hypotheses that is determined from all combinations of available data rate and the number of subpackets;
using historical transmission information to reduce the number of hypotheses comprising the plurality of hypotheses within the set of hypotheses, wherein the number of hypotheses is reduced by limiting the combinations of available data rates and the number of subpackets based on the historical transmission information; and
decoding the message using each of the hypotheses of the reduced number of hypotheses comprising the plurality of hypotheses within the set of hypotheses.
