摘要： Even when terminals having different bandwidths require different amounts of BCH information, a radio base station apparatus in a scalable bandwidth system can transmit the BCH information required by the terminals. 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.

摘要： A despreading and RAKE combining section despreads a data portion using all spreading codes and RAKE combines the despread signal. An average value calculating section calculates RAKE output average power values of all spreading codes from the RAKE combining result. A threshold setting section sets a threshold value based on the RAKE output average values of the plurality of spreading codes allocated to the own station. A spreading code determining section performs threshold determination between a RAKE output average value obtained from the spreading codes, excepting the spreading codes allocated to the own station, and determines the spreading code, which corresponds to the RAKE output average value exceeding the threshold value, as the spreading code multiplexed into the received signal. This makes it possible to accurately estimate the spreading codes multiplexed into the received signal.
摘要翻译：解扩和RAKE组合部分使用所有扩展码解扩数据部分，RAKE组合解扩信号。平均值计算部分从RAKE组合结果计算所有扩展码的RAKE输出平均功率值。阈值设定部基于分配给本台的多个扩频码的RAKE输出平均值来设定阈值。扩展码确定部分除了分配给本站的扩展码之外，从从扩展码获得的RAKE输出平均值之间进行阈值确定，并将对应于超过阈值的RAKE输出平均值的扩展码确定为扩展码复用到接收信号中。这使得可以精确地估计多路复用到接收信号中的扩频码。
