ABSTRACT:
An information communication system which includes a master station and a plurality of slave stations and enables reduction of the processing time of the whole system. When transmitting a response signal to the master station, each slave station generates not only a time slot number but also a time delay number. If a slave station detects a transmission of a response signal by another slave station having been performed prior to the time of the determined time delay number within the same time slot, the slave station does not transmit the response signal.
