Method for physical layer automatic repeat requestfor a subscriber unit

摘要

A method and apparatus for physical automatic repeat request by a subscriber unit 38. A physical layer at the transmitter receives data 34a and at the transmitters 42 formats the received data into packets having a particular encoding/data modulation. The physical layer contains n channels 41 which transmit the packets and retransmits packets upon failure to receive a corresponding acknowledgment for a given packet at an acknowledgement receiver 56. The subscriber unite 38 collects retransmission statistics and adjusts the particular encoding/data modulation at the transmitters 42 using the collected statistics.
