摘要： There are disclosed a radio communication device and others capable of generating in a short time a secret key common to a base station and a mobile station in a radio communication system using the MIMO technique and starting the encrypted communication at an early stage. In this device, in ST545, when a channel coincidence judgment unit (105) and a channel coincidence judgment processing unit (205) respectively judge that the channel matrix generated by the base station completely coincides with the channel matrix generated by the mobile station or they do not coincide completely but they can coincide finally by error correction of the secret key or the like, according to the judgment result indicated in the channel coincidence judgment signal generated in ST540-2, ST545 is followed by ST550. On the other hand, when the channel matrix generated by the base station does not coincide completely with the channel matrix generated by the mobile station and they do not coincide finally even after error correction of the secret key, ST510 is again executed after ST545.

摘要： A link adaptation method and others wherein feedback information amount can be reduced. According to this method, a receiving apparatus (100) calculates, based on a channel matrix, a capacity (C) and a stream ratio (r) that is a ratio of the reception qualities of streams, and then transmits, as feedback information, the calculated capacity (C) and stream ratio (r) to a transmitting apparatus. In the transmitting apparatus (200), the number of transmittable streams, the modulation scheme and the fed-back capacity (C) are used to calculate the encoding ratio (R) and sequence length (S) of spatial multiplexed symbols. Then, the modulation scheme (M1-Mn) of each stream is decided based on the fed-back stream ratio (r) and the sequence length (S) of spatial multiplexed symbols.

摘要： A MIMO transmitting apparatus that achieves a flexible control in accordance with variation of a propagation environment to reduce the number of retransmissions. A buffer (104) temporarily stores transport bits, which have been interleaved, in preparation for retransmission. An intra-code-word interleaver (105) performs an interleave process by all of the bits included in the symbols to be simultaneously transmitted from a plurality of transmitting antennas. When performing an intra-code-word interleave process, the intra-code-word interleaver (105) performs the interleave process in accordance with an interleave pattern notified from an interleave pattern table (107). A counter (106) counts retransmission requests, and outputs the number of retransmissions to the interleave pattern table (107). The interleave pattern table (107) stores interleave patterns to be used for intra-code-word interleave process for the respective numbers of retransmissions, and notifies the intra-code-word interleaver (105) of an interleave pattern in accordance with a number of retransmissions.
