PROBLEM TO BE SOLVED: To provide a base station implementing a physical layer automatic repeat demand. SOLUTION: The base station implementing physical layer automatic repeat demand includes a transmitter (38) and a receiver (52). The transmitter has a physical layer transmitter for receiving data, formatting the received data into packets, transmitting the packets and retransmitting packets, in response to failure to receive a corresponding acknowledgment for a given packet, an acknowledgment receiver (56) for receiving the corresponding acknowledgment, and an adaptive modulation and coding controller for collecting retransmission statistics and adjusting the particular data encoding/modulation, by using the collected statistics. The receiver (52) has a physical layer receiver for demodulating the packets, a combiner/decoder (50-1-50-n) for buffering, decoding and detecting packet errors, and an acknowledgment generator for generating an acknowledgment for each packet, if that packet has an acceptable error rate.
