  • Patent number: 10302735
    Abstract: A directional characteristic acquisition unit 51 rotates a wireless terminal 1 that is a measurement target using a terminal holding rotation mechanism 30 centering around a standard point O, measures a field intensity Pr of a radio wave received by the measurement antenna 21 at each rotation angle (?, ?) to calculate a virtual directional characteristic of a terminal antenna 1a in the wireless terminal 1. An error information output unit 60 calculates a reception angle error (??, ??), a propagation loss error E1, and a gain error E2 that occur in accordance with rotation of the wireless terminal 1, and corrects a virtual directional characteristic using these errors, using a correction unit 70, to calculate a directional characteristic Hc in a case where it is assumed that the terminal antenna 1a of the wireless terminal 1 is rotated at the position of the standard point O.

  • Publication number: 20150319754
    Abstract: When a carrier aggregation using a macro cell of a legacy carrier as a primary cell and using a small cell of a new carrier type as a secondary cell is performed, transmission of a control channel (PUCCH) of an uplink is concentrated on an uplink of the macro cell and frequency efficiency is degraded. For this reason, in a state in which the macro cell is configured as the primary cell, a serving cell transmitting the PUCCH is configured to a terminal and the terminal transmits the PUCCH using the configured serving cell.

  • Patent number: 9161277
    Abstract: Interference applied to neighbor cells during terminal handovers can be reduced in wireless communication systems containing base stations having different cell sizes. A serving cell makes handover judgment criteria easier based on pre-acquired cell size information on its own cell and cell size information of neighbor cells in order to facilitate terminal handovers from a base station with a large cell size to a base station with a small cell size. The serving cell finds evaluation function values based on the propagation state (e.g. reference signal received power) between the terminal and target cell, and the interference and load information exchanged between the base stations, and selects the terminal for handover by comparing the evaluation function value with the handover criteria value. The system selects a target cell having a good effect in lowering interference such as a cell with large reference signal received power acquired from a terminal, to serve as the handover destination.

  • Publication number: 20150257160
    Abstract: Even when a downlink radio traffic volume is larger than an uplink radio traffic volume in a radio communication system, but uplink resources are redundant in a related art radio communication system, free uplink resources could not be sufficiently utilized. In a base station having a cellular unit that performs cellular communication with a terminal, and a D2D unit that performs communication with the terminal through a device-to-device communication system, when the downlink radio resources get tight, and the uplink radio resources are redundant, the D2D unit of the base station conducts transmission and reception with the terminal with the use of the uplink radio resources.
