摘要： A base station, a mobile station and a retransmission control method for enabling communication to be more efficiently performed. In a communication system comprising a base station (100) and a mobile station (200), a time period required for the retransmission of a transport packet to complete is determined, and a retransmission control is performed, based on the required time period, to change the order of executing the retransmission of the transport packet and a handover. In this way, when it is estimated that the retransmission will complete soon, the retransmission is caused to complete in a handover source system, thereby avoiding waste of communication resources used in the preceding transmission and retransmission processes. When it is estimated that the retransmission will continue for a while, the communication resources used in the preceding transmission and retransmission processes are wasted, but a more appropriate MCS can be assigned, in a handover destination system, so as to perform a retransmission, thereby enabling communication to be efficiently performed.

A base station (100) comprises a frame generating part (150) that generates a frame in which only common information directed to all of the terminals is placed in a band, which is assigned within a band having the largest one of the bandwidths supported by the base station (100) and has the smallest one of the supported bandwidths, and in which additional information different from the common information is placed in a band which is located within the band having the largest supported bandwidth and which is different from the band in which the common information is placed; and an RF transmitting part (180) that transmits the frame via a broad channel. In this way, even when terminals having different bandwidths require different amounts of BCH information, it is possible to transmit the BCH information requested by the respective terminals.

摘要： Provided are a base station device and a mobile station device, which can lighten a cell-search processing. The base station device (100) includes a frame constitution unit (130) for forming a frame, in which a pilot symbol multiplied by a base station scrambling code assigned to that device and a plurality of sequences contained in the corresponding sequence set is arranged in at least the head or tail, and a radio transmission unit (155) for sending the formed frame. On the receiving side of the frame, the frame timing can be detected from the position of a pilot symbol contained in that frame. Since the base station scrambling code and the sequence set containing the sequences are made to correspond to each other, candidates can be narrowed to at most the base station scrambling codes of the number of the combinations of the sequences contained in the sequence set, by detecting the sequences multiplied by the pilot symbol, so that the cell search processing can be lightened.
