摘要： A radio handset includes: a signal receiver for receiving signals from a plurality of radio stations; a reception timing analyzer for analyzing reception timings of signals received by the signal reception means; a radio station selector for selecting radio stations to be used in a position calculation; and a position calculator for calculating a position of a signal reception point by using the reception timings of the signals from the selected radio stations. The radio station selector selects the radio stations to be used in the position calculation in such a manner that when reception timings of signals from two or more of the radio stations cannot be separated from one another, it is decided to exclude a signal from at least one of these radio stations.

摘要： Necessary transmission power of terminals is secured while suppressing total transmission power in base station, so that FFR technology is realized with high frequency utilization efficiency to thereby realize both of compactness of base station and increase of communication capacity. Frequency resource is divided into frequency for boundary area of cell and frequency for central area of cell. Transmission power per unit frequency is fixed in the frequency for boundary area of cell and is set to be variable in the frequency for central area of cell. Transmission power per unit frequency is adjusted so as to satisfy necessary power of terminals connected to frequency for central area of cell. When it is judged that total transmission power of base station exceeds prescribed value, terminal is moved from central area to boundary area of cell, so that total transmission power is suppressed to be equal to or smaller than standard.

摘要： Information is exchanged among multiple base stations by adaptively changing an allocation of radio resource of each base station, and reducing deterioration in a signal quality that is caused by interference of signals transmitted from multiple base stations. Communication with a terminal located in a cell center and communication with a terminal located in a cell edge are performed in different time zones. In addition, communication is performed such that time zones do not overlap in the cell edge between multiple neighbor base station devices. In addition, efficiency that is an index representing the number of bits transmittable per resource element is calculated using a scanning result of a terminal, and one base station that decides a radio resource allocation between cells decides radio resources to be allocated to a terminal located in a cell center and radio resources to be allocated to the cell edge using the efficiency information.

摘要： When DFFR is performed in a heterogeneous environment in which a pico base station coexists in the area of a macro base station and when the pico base station judges that, based on the received-signal quality report result from a mobile terminal, the macro base station causes interference to the pico base station, the pico base station reports an interference power threshold to be notified to the macro base station based on the transmission power setting value of the macro base station, the transmission power setting value of the pico base station, and the estimated interference amount calculated from the scan report result. The macro base station transmits a result of comparison between the transmission powers of multiple frequency resources and the interference power threshold, to the pico base station and the pico base station selects a frequency resource, unlikely to be affected by interference.

摘要： A DSP checks the traffic on a control channel transmitted to each terminal, and obtains a total of traffic on the control channel for each remote radio unit. The DSP transforms a correlation matrix calculated in an analysis section to a partial orthogonal matrix subjected to partial orthogonalization. The DSP divides one or more remote radio units into the groups in accordance with the sequence of rows or columns of the partial orthogonal matrix so that the total traffic for each group in which the total of traffic is added for one or more remote radio units within the group may be less than or equal to a predetermined threshold, and stores the identification number of the remote radio unit for each group in a memory.

摘要： A pilot signal is estimated by using the sampling theorem to estimate noise power in a stable manner without depending on the signal to noise ratio. A pilot signal estimation section obtains an estimated pilot signal by using the sampling theorem according to a plurality of received pilot signals sampled in the frequency domain by a sampling processor. A noise power estimation section estimates noise power by applying statistical averaging to the difference between the received pilot signal received from the sampling processor and the estimated pilot signal received from the pilot signal estimation section.
