摘要： A mobile communication system wherein the upstream radio channel interference of a macrocell connection terminal with a femtocell base station can be reduced while the consumption of radio resources caused by increase in signaling is being suppressed. The macrocell connection terminal (401) performs, based on an instruction from a macrocell base station (402), an upstream channel transmission and further reports a peripheral-femtocell detection result obtained by a measuring unit to the macrocell base station. The macrocell base station (402) instructs the terminal to perform a peripheral-femtocell detection. The identifier of the terminal and the peripheral-femtocell detection result obtained by the terminal are transmitted to a network management apparatus (404). An interference reduction instruction (frequency band allocation) and the identifier of the terminal to be interference-controlled are received from the network management apparatus, and the frequency band allocation in the upstream channel transmission of the terminal to be interference-controlled is so controlled as to satisfy the interference reduction instruction.

摘要： A transmitting apparatus, a receiving apparatus and a wireless communication method for suppressing interference between codes, while further reducing the ratio of redundant components occupying a signal to improve the transmission efficiency. The transmitting apparatus (100) transmits a signal having a frame structure in which a plurality of symbols follow a pilot symbol to which a guard interval has been added. In the receiving apparatus (200) that receives that signal, a long FFT target section acquiring part (202) acquires, from the received OFDM signal, a long FFT target section that is a target section in which delay waves are to be removed by use of a pilot symbol. A long FFT part (203) performs a fast Fourier transformation of the long FFT target section to convert it to a frequency domain signal. A frequency equalizing part (204) performs a frequency equalization of the long FFT target section by use of an interpolation result of communication line estimation value. A long IFFT part (205) performs an inverse fast Fourier transformation of the long FFT target section as frequency equalized to convert it back to a time domain signal.

摘要： Provided are a base station device and a transmission power control method that reduce interference with an uplink radio channel from a femto-connected terminal to a macrocell base station while avoiding an increase in signaling. A measurement unit (103) measures the macrocell signal reception level, and a propagation loss estimating unit (104) estimates propagation loss between a HUE and a HNB based on the HUE signal reception power, for example. A judgment unit (105) performs a first comparison of the macrocell signal reception level with a first threshold value and a second comparison of the propagation loss with a second threshold value, and an adjustment unit (106) generates a command to reduce the maximum value that is possible for the target control value for the HNB total reception power when the macrocell signal reception level is at least the first threshold value and the propagation loss is at least the second threshold value. A scheduler (107) determined a transmission rate allocated to the HUE based on the HUE signal and the maximum value that is possible for the target control value for the HNB total reception power.
