A base station apparatus, which performs radio communication with a mobile station apparatus, newly defines a minimum unit of assignment for each of the mobile station apparatuses, determines band assignment, and notifies each of the mobile station apparatuses of assignment information, when a mobile station apparatus with an RB (Resource Block) being a minimum unit of assignment and a mobile station apparatus with an RBG (RB Group) being a minimum unit of assignment coexist. In addition, the minimum unit of is newly defined by defining the number of RBs constituting an RBG for each mobile station apparatus.

摘要： To provide a system that can accommodate a greater number of terminals within a limited band and can obtain a higher transmission rate. While the number of frequency signals (spectrums) output in parallel by performing a spread spectrum from the DFT unit of each terminal is 12, the number of sub-carriers constituting one sub-channel is set at 10 or 11. In this case, the users (users A and G) allocated to the sub-channels at both ends of the band will not perform transmission of one frequency signal at the end (one sub-carrier) of all the frequency signals output from the DFT unit, whereas the users (users B to F) allocated to the other sub-channels will not perform transmission of the frequency signals at the ends (two sub-carriers). This transmission can be realized by deleting (clipping) the associated number of signals from both ends or from one end of the frequency signals output from the DFT unit of each terminal and allocating the frequency signals after clipping, to individual sub-channels.
