METHOD FOR PHYSICAL LAYER AUTOMATIC REPEAT REQUEST FOR 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.
