摘要： Since the OFDM communication method does not select whether plural sectors use a same terminal as a transmission destination, or always use it as a transmission destination, giving a preference to system throughput deteriorates channel quality of a terminal in a sector boundary, while increasing channel quality in sector boundaries greatly deteriorates system throughput. In a base station, when a sector transmits to a terminal in the front of a beam, only the sector performs the transmission, and when transmission is made to a terminal in a sector boundary off the direction of the beam, a different sector transmits to the same terminal using a same hopping pattern. Thereby, tradeoff between the channel quality of the terminal in a sector boundary and deterioration in system throughput can be minimized.
摘要翻译：由于OFDM通信方法不选择多个扇区是否使用与发送目的地相同的终端，或者始终将其用作发送目的地，所以优先考虑系统吞吐量会降低扇区边界中的终端的信道质量，同时增加信道质量在扇区边界大大降低系统吞吐量。在基站中，当扇区向波束的前端发送到终端时，只有扇区进行发送，并且当在波束的方向上向扇区边界发送终端时，不同的扇区发送到同一个终端使用相同的跳频模式。由此，可以使扇区边界中的终端的信道质量与系统吞吐量的恶化之间的权衡最小化。

摘要： A radio base station, a radio communication terminal, and a radio communication system that can efficiently utilize broadband resources even if many packets of different sizes and different QoS requirements are mixed when sent and received. When a data transmission request is sent from a radio terminal to a base station, at least one of a data transmission duration time, a transmission data transmission interval, and an expiration time is included in the data transmission request. The base station receives data transmission requests from multiple radio terminals, schedules the data transmission requests from multiple radio terminals, assigns bandwidths to the multiple radio terminals based on the duration time, transmission interval, and expiration time included in each of the data transmission requests and continues the assignment of bandwidths to the radio terminals during the duration time based on the received duration time.

摘要： [Purpose] An object of the present invention is to provide a composition for use in a formation of transparent and electrically conductive film having a low electric resistance and a high transmittance and a method for making the film mentioned above.[Composition] A mixture of inorganic indium compound and organic tin compound is combined with organic compound capable of coordinating with either of indium and tin to form an organic solution. When the mixture is heated, the inorganic indium compound and the organic tin compound coordinating partially with the organic compound react with water of crystallization of inorganic indium compound. The organic tin compound is partially subjected to hydrolysis to form an intermediate complex compound including indium and tin. This suppresses the evaporation of tin and generates a uniform film having a high transmittance and a low electric resistance. An addition of polyhydric alcohol increases the viscosity of the solution and gives a high stability to a resultant film obtained by applying the composition to the substrate and firing.

摘要： A method for manufacturing a glass fiber having a polygonal cross section is provided. According to the method, a glass fiber having an orbicular cross section is manufactured by drawing molten glass supplied into a crucible heated at higher temperatures than a softening point of glass out of a nozzle having an orbicular cross section heated at lower temperatures than the heating temperature of the crucible and at higher temperatures than the softening point of glass. Then, the glass fiber is passed through a slit of a twin roller, having a predetermined shape, whereby glass fibers having a polygonal cross section are successively manufactured. The twin roller is heated at slightly higher temperatures than the softening point of the glass.
