摘要： A mobile terminal includes circuitry, a transmitter and a receiver. The circuitry, in operation, generates a CQI for each subcarrier (SC) group of multiple subcarrier groups, a plurality of subcarriers consecutive in a frequency domain being grouped into the multiple subcarrier groups. The transmitter, in operation, reports first respective CQIs of the multiple SC groups in inconsecutive time resources based on a first period, and reports, based on a second period, second respective CQIs of the multiple SC groups in inconsecutive time resources based on the first period, the second period being longer than the first period. The receiver, in operation, receives information indicative of the first period.

摘要： In order to reduce interference between cells through hopping and use frequencies in a good propagation situation, a scheduler section carries out scheduling for determining to which user data should be sent using CQI from each communication terminal apparatus, selects a user signal to be sent in the next frame and determines in which subcarrier block the data should be sent. An MCS decision section selects a modulation scheme and coding method from the CQI of the selected user signal. A subcarrier block selection section selects a subcarrier block instructed by the scheduler section 102 for each user signal. For the respective subcarrier blocks, FH sequence selection sections select hopping patterns. A subcarrier mapping section maps the user signal and control data to subcarriers according to the selected hopping pattern.

摘要： A radio communication apparatus receives control information on one or more control channel elements (CCEs) with consecutive CCE number(s). The radio communication apparatus first-spreads a response signal with a sequence defined by a cyclic shift value that is determined among a plurality of cyclic shift values from an index of physical uplink control channel (PUCCH), which is associated with a first CCE number of the one or more CCEs, and second-spreads the first-spread response signal with an orthogonal sequence that is determined among a plurality of orthogonal sequences from the index. One of cyclic shift values used for an orthogonal sequence is determined from an index of the PUCCH, which is associated with an odd CCE number, and another one of the cyclic shift values used for the same orthogonal sequence is determined from an index of the PUCCH, which is associated with an even CCE number.

摘要： A radio communication apparatus is disclosed that enables the influence of the feedback information on the channel capacity to be kept to the minimum without reducing the transmission efficiency of information by transmission of pilot symbol. In the apparatus, a delay dispersion measuring section generates a delay profile using the received signal, and measures delay dispersion indicative of dispersion of delayed versions. A moving speed estimating section estimates moving speed of a mobile station apparatus that transmits a pilot symbol based on the variation in reception power of the pilot symbol. An other-cell interference measuring section measures other-cell interference caused by signals transmitted in cells except the cell to which the apparatus belongs. Corresponding to the delay dispersion, moving speed and other-cell interference, a pilot pattern information generating section selects a pilot pattern such that placement of pilot symbol is optimal in a frame, and generates the pilot pattern information.
