IMPLEMENTING A PHYSICAL LAYER AUTOMATIC REPEAT REQUEST FOR A SUBSCRIBER UNIT

摘要

A subscriber unit implementing physical layer automatic repeat request includes a transmitter 12 and a receiver 16. The transmitter has a physical layer transmitter 12a an acknowledge receiver 12b for receiving the corresponding acknowledgment and an adaptive modulation and coding controller 12c for collecting retransmission statistics and adjusting the particular data encoding/modulation using the collected statistics. The receiver 16 has a physical layer receiver 16a, and an acknowledgment generator 16c for generating an acknowledgment for each packet if that packet has an acceptable error rate.
