Abstract: To solve a problem that although the increase of the number of frequency blocks by allocating discontinuous subcarriers (RBs) as in OFDM enables an increase in multi-diversity effect and an improvement in throughput, the number of RB allocation patterns increases with the increase of the number of frequency blocks, resulting in an increase in the amount of information relating to the allocated RBs, the resource block allocation unit is determined when resource blocks discontinuous on the frequency axis are allocated to a terminal, and the number of bits of scheduling information indicating the allocated resource blocks by using Tree Based is set to the number of bits corresponding to the determined allocation unit.

Abstract: In order to provide a new mechanism capable of reducing an interference caused by a multipath delay, a base station includes a processor and a transmitter. The processor generates a first modulation symbol from transmission data, converts the first modulation symbol from a frequency domain signal to a first valid symbol being a time domain signal by performing inverse Fourier transform for the first modulation symbol, inserts a first guard interval into the first valid symbol, and outputs the inserted signal as a first orthogonal frequency division multiplexing (OFDM) symbol. The transmitter transmits a first OFDM signal generated based on the first OFDM symbol. The processor leaves blank at least one of a second OFDM symbol adjacent to the first OFDM symbol or at least one of a plurality of subcarriers configuring the first valid symbol.

Abstract: Provided is a technique capable of reporting resource block allocation information with no waste when an allocated resource block is reported, because in the current LTE downlink, the waste of the amount of resource allocation information increases in some cases since a restriction is imposed such that 37-bit fixed scheduling information is transmitted. A resource block group consisting of at least one or more resource blocks continuous on the frequency axis is allocated to a terminal, and the number of controlling signals for reporting allocation information indicating the allocated resource blocks is determined.

Abstract: An induction heating device and an induction heating method are provided. The entire areas to be heated of the workpiece can be uniformly heated to a predetermined high temperature, and uniform heating is possible even when the workpiece deforms in a non-uniform manner during heating. When areas to be heated are established on a workpiece so as to extend in one direction and the areas to be heated are induction-heated, the deformation amount on one edge of the areas to be heated is different from that on the other. This induction heating device includes; heating coils facing a portion of the areas to be heated when the workpiece is induction-heated; and a relative transfer means for transferring the workpiece and the heating coils along one direction in a relative manner, and the heating coils are disposed so as to correspond to the areas to be heated during the heating period.
