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.

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.

摘要： There are provided a base station device and a mobile station device for increasing the speed of cell search by introducing identification of TTI timing into the cell search. In the base station device (100), a frame configuration unit (120) forms a frame by arranging a TTI synchronization sequence (SCH1 sequence) used for identifying the frame timing and a TTI synchronization sequence (SCH2 sequence) used for identifying the TTI timing in such a manner that they are not superimposed on the same symbol specified by the frequency and the time. A radio transmission unit (145) sends the frame. The frame configuration unit (120) arranges the frame synchronization sequence at a predetermined position from the frame starting symbol and the TTI synchronization sequence at a predetermined position from the TTI starting symbol. The mobile station device (200) receiving the frame detects the TTI timing by using the TTI synchronization sequence.

摘要： There are provided a base station device transmitting a frame capable of performing cell search without being affected by arrangement of a pilot channel and a mobile station device performing cell search by using the frame. In the base station device (100), a frame formation unit (120) forms a frame by arranging a P-SCH sequence used for synchronization of a frame timing on some symbols of multi-carrier symbols at a predetermined position from the frame head in the frequency direction and arranging an S-SCH sequence corresponding to a base station scrambling code so that it is not overlapped on some of the multi-carrier symbols at a predetermined position from the frame head with the same symbol as the frame synchronization sequence. The frame is received by the mobile station device (200) and the S-SCH is demodulated. Thus, it is possible to directly identify the base station scrambling code without using a pilot channel.

摘要： A scalable bandwidth system wherein even if a terminal does not know the breakdowns of the services in all of the bandwidths, it can perform a correlation processing of synchronous channels (SCH). A base station repetitively transmits a synchronous channel, by unit of the shortest bandwidth (e.g., 1.25 MHz) of a plurality of bandwidths served by the system, over the whole band of the longest bandwidth (e.g., 5 MHz). The terminal calculates the correlation between a synchronous channel sequence signal of the unit of the shortest bandwidth held in advance and the repetitively transmitted synchronous channel, and determines, as a frame timing, a timing at which the maximum correlation value is obtained.

摘要： A MIMO transmitting apparatus for improving the frame timing detection performance in a cell search. In the MIMO transmitting apparatus, a pilot pattern designating part (108) designates a pilot pattern corresponding to a scrambling code and sends the designation to pilot inserting parts (110-1 to 110-4). The pilot inserting parts (110-1 to 110-4) each insert pilot symbols in accordance with the designation of the pilot pattern designating part (108) into predetermined positions of a respective stream. A scrambling pattern designating part (112) designates a scrambling pattern, i.e., a pattern of reversing the signs of the subcarriers of the pilot symbols in each stream and sends the designation to scrambling parts (114-1 to 114-4). The scrambling parts (114-1 to 114-4) reverse the signs of a half number of subcarriers corresponding to the end or front symbols of the streams in accordance with the designation of the scrambling pattern designating part (112).
