摘要： It is possible to improve the CQI reception performance even when a delay is caused in a propagation path, a transmission timing error is caused, or a residual interference is generated between cyclic shift amounts of different ZC sequences. For the second symbol and the sixth symbol of the ACK/NACK signal which are multiplexed by RS of CQI, (+, +) or (−, −) is applied to a partial sequence of the Walsh sequence. For RS of CQI transmitted from a mobile station, + is added as an RS phase of the second symbol and − is added as an RS phase of the sixth symbol. A base station (100) receives multiplexed signals of ACK/NACK signals and CQI signals transmitted from a plurality of mobile stations. An RS synthesis unit (119) performs synthesis by aligning the RS phase of CQI.

摘要： Provided is a radio communication mobile station device capable of preventing a transmission delay when a transmission data amount is increased in a radio communication system where persistent scheduling is performed. In this device, an MCS selection unit (104) selects a first MCS if the transmission data amount accumulated in a buffer of a data control unit (105) is smaller than a threshold value and selects a second MCS having a higher MCS level than the first MCS if the transmission data amount is not smaller than the threshold value. Thus, in a mobile station (100), data encoded and modulated according to the first MCS is transmitted during a normal state when the transmission data amount is small, and data encoded and modulated according to the second MCS having a higher MCS level than the first MCS is transmitted when the transmission data amount is increased to a large amount.

摘要： Signals received from antennas are input to weighting factor calculation sections 105 and 106. Weighting factor calculation section 105 calculates weighting factors so as to eliminate an interference signal using the antenna reception signals and known signals of a desired signal. Weighting factor calculation section 106 sequentially updates weighting factors so as to minimize the difference between a combined signal and its reference signal using the weighting factors calculated by weighting factor calculation section 105 as the initial values. On the other hand, reception quality measurement section 108 measures the reception quality of the combined signal and outputs the measurement result to weighting factor switching section 107. After receiving the measurement result, weighting factor switching section 107 switches weighting factors to be used for combination at the time the reception quality changes.

摘要： A radio transmission device and a radio communication method employ sequence length decision units which hold a correspondence in which one basic sequence length is set for a plurality of transmission bandwidths. The sequence length decision units acquire transmission bandwidth information and decide a sequence length corresponding to the acquired transmission bandwidth information. A decision is made as to which of the cyclic extension process or the truncation process is to be executed on a Zadoff-Chu sequence according to the sizes of the acquired transmission bandwidth information and the basic sequence length. Then, a difference between the transmission bandwidth and the basic sequence length, i.e., the number of possible cyclic extension/truncation symbols, is obtained.
