A communication system forms a frame format such that each of a plurality of base stations is assigned with one of a plurality of frequency bands, which are orthogonally frequency divided. In accordance with the frame format, the plurality of the base stations transmit a frame signal including a preamble signal, a broadcast signal that allows the plurality of the terminal apparatuses to commonly recognize information indicating an area of presence of transmission data disposed within the assigned frequency band, and the transmission data disposed within the assigned frequency band, periodically in a downlink frame period. Each of the plurality of the terminal apparatuses detects a path with the maximum level from the preamble signal in the received frame signal to establish synchronization with the base station based on the detected path to acquire the transmission data in the frequency band recognized based on the broadcast signal. In this way, properties of WiMAX (IEEE 802.16) and IEEE 802.11 communication schemes can be combined.
