Abstract
A wireless terminal receives a first broadcast signal transmitted from a wireless base station; detects whether a part of a wireless terminal ID of the own wireless terminal is included in the first broadcast signal received in the broadcast signal reception or not and determines that the second broadcast signal is to be continuously received when the part of the wireless terminal ID is included; and receives the second broadcast signal when it is determined in the broadcast signal determination that the second broadcast signal is to be received, stops receiving data transmitted from the wireless base station when assignment information to be transmitted to the own wireless terminal is not present in the received second broadcast signal, and receives data transmitted from the wireless base station to the own wireless terminal based on the information on the assignment position of the wireless slot included in the second broadcast signal when the assignment information to be transmitted to the own wireless terminal is present in the received second broadcast signal.
