IMPLEMENTING A PHYSICAL LAYER AUTOMATIC REPEAT REQUEST FOR ASUBSCRIBER 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 receivin g 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.
