Title: Radio communication method
Inventor: TAKANASHI HITOSHI
IPC: H04L1/22
Filed: 1994-07-25
Abstract: PURPOSE:To decrease the frequency of retransmission and to improve throughput by deciding whether there is any error in a received signal or not, requesting retransmission when there is the error, and performing retransmission when the retransmission request is received. CONSTITUTION:In the case of a frequency f2, time is from 3 to 8, its level is low and any error occurs. Concerning a slot transmitted from a radio station 1 to a radio station 2 at the time 3, there is any error. At time 4, the radio station 2 requests the retransmission to the radio station 1. Since this retransmission is requested at a frequency f1, when the level is high, the transmission is possible without fail. Namely, the radio station on the reception side decides whether there is any error in the received signal or not corresponding to an error detecting code or an error correcting code and when there is the error, the request of retransmission is transmitted to the radio station, where that signal is transmitted, at any frequency different from the error detected slot. When the request of retransmission is received, the retransmission is performed. Thus, the probability to perform retransmission without fail can be increased and throughput can be improved.
