摘要： A wireless station apparatus is proposed that solves the problem of deterioration of communication quality. An arrival direction detection unit (13) detects the direction of arrival of uplink signals received by a wireless receiver (11). A mobile station determination unit (12) determines whether the transmission-origin mobile station of the uplink signals that are received by the wireless receiver (11) is a permitted mobile station or a nonpermitted mobile station. Based on the uplink signals received by the wireless receiver (11) and the determination result of the mobile station determination unit (12), an antenna adjustment unit (14) finds the degree of interference of permitted mobile stations and nonpermitted mobile stations in the direction of arrival that was detected in the arrival direction detection unit (13). The antenna adjustment unit (14) adjusts the direction of directivity of the reception antenna (10) in accordance with the degree of interference that was found.

摘要： A subcarrier allocation apparatus of the present invention includes: memory (12) that stores allocation patterns of links for allocation of subcarriers to the links; selector (11) that selects the subcarriers one by one in order; allocation evaluation value calculators (13) that are arranged in conjunction with cells of base stations and that calculate, for each allocation pattern, allocation evaluation values indicating desirability of allocation in the corresponding cells at the time of the allocation of the subcarrier currently selected by selector (11) to the links in accordance with the allocation pattern; adder (14) that adds, for each allocation pattern, the allocation evaluation values calculated by allocation evaluation value calculators (13); and maximum value detector (15) that detects a maximum value from the addition result of the allocation evaluation values added by adder (14) and that determines the allocation pattern, in which the addition result indicates the maximum value, as an optimal allocation pattern of the subcarrier currently selected by selector (11).

摘要： A disclosed radio communications apparatus adaptively controls a modulation method and coding rate (MCS) of a data channel in accordance with received channel quality information (CQI). This apparatus includes a first data table indicating a first corresponding relationship of the MCS with respect to the CQI; a second data table indicating a second corresponding relationship of transmission power of a control channel with respect to the CQI; a first selection portion that accesses the first data table so as to select the MCS of the data channel in accordance with the received CQI; a second selection portion that accesses the second data table so as to select the transmission power of the control channel in accordance with the received CQI; and a transmission portion that transmits the data channel in accordance with the selected MCS and the control channel at the selected transmission power.
