WIRELESS COMMUNICATION SYSTEM AND WIRELESS COMMUNICATION METHOD

摘要

A wireless communication system including a base station and a plurality of terminals, the wireless communication system uses a frame including a plurality of sub-frames, the sub-frames including a plurality of data symbols and guard intervals between the data symbols, each sub-frame being transmitted every frame period, and a different guard interval length being available for each sub-frame; configured to insert a guard interval of a fixed length between each of the data symbols in a specified sub-frame of the frame; a placement information determination section configured to determine placement information pertaining to a placement of a sub-frame to which guard intervals different in length from the guard interval of the fixed length are to be applied; and configured to multiplex the placement information determined by the placement information determination section into a transmission; wherein the plurality of terminals is notified of information containing the placement information.
