摘要:
A base station receives channel state information corresponding to each of spare coordinated groups from each of user devices. A first group includes a plurality of coordinated groups arranged in advance. The spare coordinated groups corresponding to each user device are such as selected from the first group and include at least a service sector of best channel quality obtained measurement by the user device. The base station specifies a user device group corresponding to each of coordinated groups contained in each of coordinated group patterns. The user device group corresponding to the coordinated group is formed of user devices having the coordinated group in their spare coordinated groups. The base station uses channel state information reported from the user devices of the user device group corresponding to the coordinated group as a basis to perform user scheduling on the coordinated group.

The present invention makes it possible to transmit and receive CSI-RSs adequately even when the number of CSI-RSs increase following the increase of antennas. The present invention provides a base station apparatus (20) that transmits CSI-RSs to a mobile terminal apparatus (10A) which is capable of receiving CSI-RSs for channel state measurement from a plurality of antennas, and to a mobile terminal apparatus (10B) which is capable of receiving CSI-RSs from a smaller number of antennas than the mobile terminal apparatus, and this base station apparatus has a CSI-RS allocation section (211) which allocates CSI-RSs for the number of antennas which the mobile terminal apparatus (10A) supports, to radio resources, and a transmitting/receiving section which reports, to the mobile terminal apparatus (10A), the resources where the CSI-RSs are allocated, and which, upon reporting the resources where CSI-RSs are allocated, to the mobile terminal apparatus (10B), reports part of the resources as resources to be muted.

Provided is a radio communication system using a relay transmission technique capable of optimizing use of radio resources in a radio base station and preventing reduction in capacity of the whole system. The relay frequency allocation method of the present invention has the steps of: radio base stations (10a) and (10b) transmitting downlink data to a relay station (30) using respective backhaul links established between the relay station (30) and the radio base stations (10a) and (10b); and the relay station (30) transmitting the downlink data received from the radio base stations (10a) and (10b), to a relay terminal (20b) by using an access link established between the relay station (30) and the relay terminal (20b).
摘要:
To provide a cell selecting method in which an optimal cell can be selected in the case of relay transmission. The cell selecting method includes: in a radio base station apparatus, determining a specified sub-frame including data for measuring reception quality in a mobile terminal device; and in a mobile terminal device, measuring first reception quality using a reference signal of the specified sub-frame transmitted from the radio base station apparatus and second reception quality using a reference signal of the specified sub-frame transmitted from the radio base station apparatus through a radio relay station apparatus, and transmitting the first reception quality and the second reception quality to the radio base station apparatus; and in the radio base station apparatus, selecting a cell to which the mobile terminal device is connected using the first reception quality and the second reception quality, and transmitting information on the selected cell to the mobile terminal device.
摘要:
A radio relay station apparatus and a mobile terminal apparatus that, even if a radio relay station apparatus is provided, can reduce the amount of interference from the radio relay station apparatus and increase the throughput, are provided. The radio relay station apparatus of the present invention decides the number of mobile terminal apparatuses under the subject cell and controls transmission power based on this number of mobile terminal apparatuses, or measures the received power of the signal from another radio relay station apparatus or a radio base station apparatus and controls transmission power based on this received power.

An optical pickup device or an optical disk device includes: a light source 11 that emits a laser beam toward an optical disk 25; an optical receiver 18 that detects light reflected from the optical disk 25; and an astigmatism-generating element 31 that generates light used for focus control in a condition where a focusing position on one of two perpendicular cross sections including an optical axis of the light reflected from the optical disk 25 is located ahead of the optical receiver 18 and a focusing position on the other cross section is located behind the optical receiver 18. The astigmatism-generating element 31 is a Fresnel mirror 31a configured to include a plurality of reflecting mirrors, and an imaginary surface 31d that connects the tips of the reflecting mirrors is curved in a concave shape toward a light incidence side.
摘要:
The invention provides mutated Pseudomonas exotoxins (PE) that have reduced immunogenicity compared to PEs containing the native sequence. The PEs of the invention have one or more individual mutations of positions of the native sequence of PE that reduce antibody binding to one or more PE epitopes. Nucleic acids encoding the mutated PEs, chimeric molecules comprising them, compositions comprising the chimeric molecules and methods of using them, are also provided.

摘要:
A novel monoclonal antibody that specifically recognizes phosphatidylinositol-3,4,5-triphosphate (PIP3) but does not cross-react with structurally similar phospholipid antigens is advantageous for PIP3-specific immunoassay. The gene in the variable regions of the monoclonal antibody has been identified, which enables producing recombinant antibodies.
摘要:
If an optional paper feeding deck or furnisher, or paper stacker, is connected to an image forming apparatus (such as a printer), such optional devices are to be controlled by connecting the paper conveyance control apparatus to control those options. Such an image forming apparatus has a video controller to convert the printer language sent from a high-order device such as a host computer, into bit map data and a printer engine to print the bit map data. Such a paper conveyance control apparatus, being electrically connected to the video controller, has a memory to be shared with the video controller. The video controller writes the job schedule in the shared memory. The paper conveyance control apparatus controls the optional device according to the written job schedule.
