摘要： Wireless communication with a communicating apparatus that is a limited band terminal capable of receiving only part of frequencies. A frequency channel allocating section allocates frequency channels, a terminal reception quality information processing section calculates an optimal modulation rate and required transmit power for each subcarrier, a subcarrier power control section controls a level of transmit power for each subcarrier, and a determining section checks a reception bandwidth of a communicating apparatus, while determining whether the communicating apparatus is a full band terminal capable of receiving all the frequency channels in the system band or a limited band terminal capable of receiving only part of frequencies. When the communicating apparatus is the limited band terminal, the transmit power of all or part of subcarriers is decreased in a frequency channel that is adjacent to a reception band allocated to the communicating apparatus and that is allocated to another communicating 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.

摘要： A communication means which allocates a terminal identifier to a destination communication apparatus and carries out communication with the destination communication apparatus by use of a plurality of functions including an identifier generation section 152 for generating different terminal identifiers corresponding to a function used and an identifier allocation section 114 having an identifier selecting section 104 for allocation to the destination communication apparatus. Using a plurality of different terminal identifiers (terminal function identifiers), a function to be used between the destination can be specified. Moreover, it is possible to optimize the size of a memory for storing information required for adaptive modulation control.

摘要： Consecutive subcarriers are reserved, and the reserved consecutive subcarriers are properly allocated to a terminal. The invention is a scheduling method that allocates, within an available band, a block composed of one or more subcarriers and used for signal transmission by a communication terminal being a destination of communication, and the method includes the steps of selecting (S208), with a higher priority, communication terminals having different number of the subcarriers composing the block as simultaneously communicating terminals that perform signal transmission simultaneously, and allocating (S214) the block for use by the simultaneously communicating terminals within the available band.
