摘要： 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.

摘要： Provided is a wireless communication technique capable of supporting communication using a single component carrier, and communication using a plurality of component carriers. The communication using the plurality of carriers comprises a processing means for performing the signal processing in accordance with each of the carriers with respect to the common signal sequence used by the plurality of carriers. The present invention makes it possible to cope with the communication employing a single component carrier and the wireless communication employing a plurality of the component carriers. Further, PAPR of the reference signals can be made small because there is no possibility that the identical CAZAC sequence is used among the component carriers when a plurality of the component carriers are employed.

摘要： Provided is a wireless communication technique capable of supporting communication using a single component carrier, and communication using a plurality of component carriers. The communication using the plurality of carriers is characterized by using a different signal sequence in each of the carriers, and using the signal sequences as reference signals. The present invention makes it possible to cope with the communication employing a single component carrier and the wireless communication employing a plurality of the component carriers. Further, PAPR of the reference signals can be made small because there is no possibility that the identical CAZAC sequence is used among the component carriers when a plurality of the component carriers are employed.

摘要： The problem is that, in a mobile wireless system, when more than one frequency block composed of resource blocks that are consecutive on a frequency axis is assigned to one mobile station, the multi-diversity effect due to scheduling increases by the number of assigned frequency blocks being increased, but the overhead caused by the scheduling information increases. Accordingly, there is a tradeoff between the multi-diversity effect and the scheduling overhead. However, when the aforementioned tradeoff was considered with OFDM and SC-FDMA, the same fixed number of frequency blocks would have been used for all mobile stations. Accordingly, an optimization that takes into account the tradeoff between the multi-diversity effect and scheduling overhead has not been sufficiently achieved. In a wireless communication system, the maximum frequency block number, which is the maximum number of the aforementioned frequency blocks assigned to the same mobile station, is set based on system information, which is information pertaining to the base station installation environment and the mobile station or the mobile station's communication status, and the base station assigns no more resource blocks than the aforementioned maximum frequency block number.

摘要： 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.
