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: A communications system 1 has: an eNB 20 having a feedback conditions control unit 22 that controls feedback conditions in accordance with call priority and a control unit 21 that controls communications with a mobile station 10 on the basis of feedback information that includes reception quality in the mobile station 10 and decoding results for a received call, said feedback conditions being for determining whether or not transmission of the feedback information is necessary; and the mobile station 10 having a priority setting unit 13 that sets a priority level for the mobile station itself, a reception quality measuring unit 11 that measures the reception quality of reference signals from the eNB 20, and a feedback requirement determination unit 12 that determines whether or not transmission of feedback information is required, on the basis of the feedback conditions.

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: A base station includes a transmitter configured to transmit a downlink control information to a user equipment, the downlink control information being generated based on one of (1) a first uplink allocation information indicating a first frequency block corresponding to a first plurality of subcarriers which are contiguous in frequency and (2) a second uplink allocation information indicating a second frequency block corresponding to a second plurality of subcarriers which are contiguous in frequency and a third frequency block corresponding to a third plurality of subcarriers which are contiguous in frequency, the second frequency block and the third frequency block being separated in frequency.
