1. A method for rate adaptation using a two-loop operation distinguishing between a retry packet and a new packet, comprising:
determining whether to transmit the retry packet or the new packet;
reducing a maximum rate in response to determining to transmit the retry packet;
transmitting the retry packet based on the reduced maximum rate;
determining a number of transmitted packets in response to determining to transmit the new packet;
determining a packet error rate (PER) accumulated over the determined number of transmitted packets in response to determining to transmit the new packet;
selecting the maximum rate based on the PER; and
transmitting the new packet based on the selected maximum rate.
