Abstract
A wireless communicating method for a system having a plurality of communicating stations and a controlling station for controlling an accessing operation of the communicating stations in which the controlling station is disposed between the communicating stations, a communication signal is transmitted and received between each of the communicating stations and the controlling station, as the communication signal has a control area and a data area structured as a frame on a time division basis. The method includes the steps of causing a communicating station to transmit a communicating station state change request signal to the control station, causing the control station to transmit a communicating station state signal to the communicating station so as to enter the relevant communicating station into a sleep state, and causing a communicating station in the sleep state to receive a start command signal that causes the relevant communicating station to cancel the sleep state.
