摘要

A METHOD FOR PHYSICAL AUTOMATIC REPEAT REQUEST BY A SUBSCRIBER UNIT (16). A PHYSICAL LAYER AT THE TRANSMITTER (12A) RECEIVES DATA AND FORMATS THE RECEIVED DATA INTO PACKETS HAVING A PARTICULAR ENCODING/DATA MODULATION. THE PHYSICAL LAYER CONTAINS N CHANNELS WHICH TRANSMIT THE PACKETS AND RETRANSMITS PACKETS UPON FAILURE TO RECEIVE A CORRESPONDING ACKNOWLEDGMENT FOR A GIVEN PACKET. AN ADAPTIVE MODULATION AND CODING CONTROLLER (12C) IN THE TRANSMITTER (12A) COLLECTS RETRANSMISSION STATISTICS AND ADJUSTS THE PARTICULAR ENCODING/DATA MODULATIONS USING THE COLLECTED STATISTICS.
