  • 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.

  • Patent number: 9083450
    Abstract: A macro base station includes a communication prohibited period setting unit of setting an uplink communication prohibited period to a user equipment belonging to the base station, and prohibits an uplink communication from the user equipment to a wireless communication base station per se during the uplink communication prohibited period. The user equipments belonging to the wireless communication base station per se and the second base station are divided into plural groups, and the uplink communication prohibited period is set to different time periods for the respective groups. Thereby, a communication characteristic is prohibited from being deteriorated at the second base station by an interference affected with the second base station separately from the first base station by the user equipment communicating with the first base station in the uplink communication.

  • Patent number: 8964777
    Abstract: In a radio communication system where a base station provides blank time slots to avoid inter-cell interference, a decrease in throughput by an excess or shortage of blank time slots is prevented. This invention relates to a radio system that avoids interference in cooperation between base stations by providing blank time slots by a (first) base station. Other (second) base stations detect the number of served terminals affected by interference from the first base station that sets blank time slots, calculate required blank time slots so that the number of required blank time slots will increase with an increase in the number of terminals located in cell edges, and send a notification of the required blank time slots to the first base station. The first base station determines whether system throughput is anticipated to improve, based on the above notifications, and adjusts the length of blank time slots.

  • Patent number: 8923866
    Abstract: In femtocell operation, when a wireless communication terminal whose ID is not registered (ID unregistered terminal) has entered a femtocell's area, the disclosed invention prevents interference between the femtocell and the ID unregistered terminal and interference between the ID unregistered terminal and an ID registered radio communication terminal and prevents a decrease in the throughput of the femtocell and these terminals. In a radio coverage area formed by a radio base station, if a drop of received power from a radio communication terminal occurs and the frequency of reporting the ID of the base station now communicating with the terminal has become less than a given value, it is decided that the terminal is located indoors. For the terminal, if its handover to a femtocell was found to be rejected by MME, the terminal is temporarily permitted to be handed over to a femtocell.
