METHOD FOR PHYSICAL LAYER AUTOMATIC REPEAT REQUEST FOR A BASE STATION

摘要

A physical automatic repeat request method implemented by a base station (30) having a transmitter (38) and a receiver (52). A physical layer, at the transmitter (38) receives data and formats the received data into packets having a particular encoding/data modulation. The physical layer transmits the packets and retransmits packets upon failure to receive a corresponding acknowledgment (56) for a given packet. An adaptive modulation and coding controller in the transmitter collects retransmission statistics (60) and adjusts the particular encoding/data modulation using the collected statistics (62).
