Claim:
1. A method of deciding a target set of transmission rates of a wireless communication device, which transmits data packets according to a plurality of transmission rates of the target set of transmission rates, comprising: providing a plurality of candidate sets of transmission rates; transmitting a plurality of data packets according to a primary set of transmission rates; counting retry times of the data packets in a predetermined time period and generating a counting result accordingly; and selecting one of the candidate sets of transmission rates to be the target set of transmission rates according to the counting result; wherein the counting result is relevant to probability of the data packets encountering collision, the candidate sets of transmission rates comprise at least a candidate set of high transmission rates and a candidate set of low transmission rates, an average of the transmission rates of the candidate set of high transmission rates is larger than an average of the transmission rates of the candidate set of low transmission rates, and the step of selecting one of the candidate sets of transmission rates to be the target set of transmission rates according to the counting result comprises:
