BASE STATION IMPLEMENTING A PHYSICAL LAYER AUTOMATIC REPEAT REQUEST

摘要

1. Technical Result Improvement of communication in wireless communication systems. 2. Essence A base station includes a transmitter 38 and a receiver 52. The transmitter has a physical layer transmitter for receiving data, formats the received data into packets transmitting the packets and retransmitting packets in response to failure to receive a corresponding acknowledgment for a given packet; an acknowledgment receiver 56 for receiving the corresponding acknowledgment; and an adaptive modulation and coding controller for collecting retransmission statistics and adjusting the particular data encoding/modulation using the collected statistics. The receiver 52 has a physical layer receiver for demodulating the packets; a combiner/decoder (50-1-50-n) for buffering, decoding and detecting packet errors; and an acknowledgment generator for generating an acknowledgment for each packet if that packet has an acceptable error rate. 3. Field of Application Wireless communication systems.
