COMMUNICATION TERMINAL DEVICE, COMMUNICATIONS SYSTEM AND POWER CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To attain power saving and signal collision avoidance of a communications terminal in a wireless network.

SOLUTION: 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 own signal. Each station sets its transmission timing, such that it will not overlap the transmission timing of the other stations, by referring to data elements contained in a beacon signal. The transmission timing in the stations is determined for each transmission.
