摘要： In order to perform appropriate reception quality control on each mobile station in a multimedia broadcast/multicast service, a layered coding section 101 encodes input data by dividing the input data into two layers and obtains a first layer code string and a second layer code string. The first layer code string is input to a CRC code addition section 102 and a CRC code for an error inspection is added thereto at every predetermined block. On the other hand, the second layer code string is input to a CRC code addition section 103 and a CRC code for an error inspection is added thereto at every predetermined block. The first layer code string and the second layer code string with the CRC codes added are input to a layered modulation section 104 and the layered modulation section 104 modulates a plurality of code strings coded by being divided into a plurality of layers in such away that error rates differ hierarchically among the plurality of code strings and a radio section 105 sends the modulated symbol.

摘要： It is possible to use a frequency of a preferable propagation condition while reducing the other cell interference by hopping. A scheduler section (102) performs scheduling for deciding a user to whom data is transmitted, by using the CQI from each communication terminal device, selects a user signal to be transmitted in the next frame, and decides a sub-carrier block by which the transmission is performed. An MCS judgment section (103) selects a modulation method and a coding method from the CQI of the user signal selected. A sub-carrier block selection section (110) selects a sub-carrier block specified by the scheduler section (102) for each user signal. For each of the sub-carrier blocks, the hopping pattern is selected by FH-sequence selection sections (111-1 to 111-n). A sub-carrier mapping section (112) maps the user signal and the control data to the sub-carrier according to the hopping pattern selected.

摘要： It is possible to provide a radio communication device and a CQI generation method capable of reducing the total number of CQI when reporting CQI for each level in a hierarchized RB. In the device and the method, the RB hierarchy is made as follows: a plurality of groups each consisting of the same number of RB are made to be one level, a group consisting of a plenty of RB is made to be a lower level, and a group consisting of a small number of RB is made to be a higher level. UE reports CQI for each level to Node B according to the RB reception quality at a longer cycle for lower level and at a shorter cycle for a higher level.
