EP1587242A3

Advanced power saving in communication terminal, communication system and power control method

Abstract

Each station makes a transition to a power saving state autonomously in response to the reception of signals from the other stations in the same group and the transmission of its own signal. Each station sets its transmission timing such that it does not overlap the transmission timing of the other stations, by referring to data elements included in a beacon signal. The transmission timing in the stations is determined for each transmission.
