Title:
BASE STATION DEVICE AND PACKET TRANSMITTING METHOD
Document Type and Number:
Japanese Patent JP3530177
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent drop in transmission efficiency by transmitting other packets by a time slot assigned packet for retransmission when a packet transmitted is correctly demodulated.
SOLUTION: A first scheduler 152 executes scheduling for determining a destination unit based on a radio line quality prediction result from a radio line quality predicting part 107. A second scheduler 153 executes scheduling for the time slot that the first schedule 152 is assigned packet for retransmission based on the radio line quality prediction result from the radio line quality predicting part 107 and the scheduling result of the first scheduler 152. A transmission control unit 155 controls a transmission queue 156, an error correction encoding part 158, and a modulation unit 159 corresponding to the scheduling result of the first scheduler 152 when ACK signal is inputted, and corresponding to the scheduling result of the second scheduler 153 when NACK signal is inputted.
