摘要： A channel state information compressing apparatus includes a time-to-frequency region converter that converts a region for channel state information which indicates a state of each communication channel from a time region to a frequency region; and an adaptive selector that selects each frequency component to be included in compressed data based on electric power of the frequency component from among frequency region data obtained by the time-to-frequency region converter. The channel state information compressing apparatus outputs the compressed data consisting of each selected frequency component, and information for identifying each frequency component which forms the compressed data.

摘要： A wireless communication system, relay station device, and base station device reduce dead zones in which communication with the base station device is not possible, and enable expansion of service areas. The BS transmits to the RS burst packets and MAP messages including information providing notification of the timing of information transmission and reception. The RS receives the MAP messages and burst packets. The RS stores, in the Preamble Present bits in MAP messages, information providing notification of the preamble transmission timing to control synchronization of reception by the SSs, and transmits the MAP messages to the SSs. The RS transmits burst packets to which preambles are appended to the SSs.

摘要： There is provided a terminal that is capable of not sending a useless probe request to detect a stealth access point. The terminal communicates with a normal access point that reports a network identifier and a stealth access point that does not report a network identifier. The terminal includes an access point information accumulating section 103 for accumulating access point information that indicates whether each access point is a normal access point or a stealth access point, a beacon signal detecting section 101 for listening for and detecting a beacon signal, a probe request sending section 105 for sending a probe request, and an access point finding control section 102 for controlling the beacon signal detecting section 101 to detect the beacon signal with respect to the normal access point, and controlling the probe request sending section 105 to send the probe request with respect to the stealth access point.
