Abstract: A base station BS transmits downlink data to a relay station RS. A mobile station MS transmits uplink data to the relay station RS. The relay station RS determines a first modulation scheme for transmitting the uplink data to the base station BS, and determines a second modulation scheme for transmitting the downlink data to the mobile station MS. The relay station RS multiplies a symbol sequence obtained by the first modulation scheme by a symbol sequence obtained by the second modulation scheme for each symbol, and multicasts the multiplication result to the base station BS and the mobile station MS.

Abstract: Node-B transmits a power profile of each frequency of transmission data as a step function to a UE. Each UE measures the amount of interference of a received signal, evaluates SINR over the entire frequency band with the power of the received signal, and transmits the evaluation result to Node-B. Node-B evaluates the interference profile in Node-B from the information about the SINR transmitted from the UE and the power of the transmission signal, and determines the frequency profile of the power of the signal transmitted to the UE.

Abstract: A radio communication system includes a base station, a mobile station, and a relay station which is provided for each sector, and divides an assigned band into a plurality of sub-bands for use. A different sub-band is used for each sector for a first communication link. A sub-band different from the sub-band in the first communication link is used for each sector for a second communication link. When a mobile station is located in a first zone, substantially the same sub-band as the second communication link is used in each sector for a third communication link. When a mobile station is located in a second zone farther from the base station than the first zone, a sub-band different from those of the first communication link and the second communication link is used for a fourth communication link. Thus, the interference among the communication links can be suppressed.

Abstract: In a telecommunication network, each node is provided with the same physical topology information relating to a physical construction of telecommunication paths included in the telecommunication network and with the same logical topology information relating to routing of telecommunication paths. When a failure occurs, restoration is effected by transmitting information relating to the failure that has occurred in the telecommunication network, throughout the network. Each node that receives the information relating to the failure determines alternative paths for bypassing the failure using the information relating to the failure, the physical topology information, and the logical topology information. Then service is switched to the alternative paths.

Abstract: A SRAM has a precharge circuit disposed for each column of memory cells, the precharge circuit including a first precharge section disposed between two of memory cells and a pair of second precharge sections each disposed at the periphery of the column. The first precharge section has a configuration similar to the configuration of each memory cell, whereas the second precharge section has a different configuration. A dummy cell is disposed between the second precharge section and a memory cell for prevention of micro-loading effect.

Abstract: In a semiconductor memory device including a normal memory constituted by a plurality of normal memory cells and a redundant memory constituted by a plurality of redundant memory cells, a predecoder decodes an address signal and outputs a corresponding address selection signal to an array interconnection. A normal address decoder selects a normal memory cell in the normal memory on the basis of an address selection signal from the predecoder. A redundant address decoder selects a redundant memory cell in the redundant memory on the basis of an address selection signal from the predecoder. When a defective normal memory cell in the normal memory is designated by the address signal, a control unit outputs, to the predecoder, an inactivating signal for inactivating the normal memory and a redundant memory cell selection signal for selecting the redundant memory cell in the redundant memory in place of the defective normal memory cell in the normal memory.

Abstract: In a voltage transferring device connected between a voltage supplying section and a voltage receiving section, the voltage supplying section supplies, in a transferring period, a boost voltage having a boost level to the voltage receiving section. The voltage supplying section has, in a non-transferring period, a non-transferring voltage which has a non-transferring level smaller than the boost level. A transferring field effect transistor has a source electrode connected to the voltage supplying section and a drain electrode connected to the voltage receiving section. A controlling circuit is connected to a substrate electrode of the transferring FET. The voltage controlling circuit supplies, in the transferring period, a high voltage having the boost level to the substrate electrode of the transferring FET. The controlling circuit supplies, in the non-transferring period, a low voltage having the non-transferring level to the substrate electrode of the transferring FET.

Abstract: A path switching system and method for a multiple-node ATM network, in which a plurality of paths can be simultaneously switched preserving proper correspondence thereof. A key choosing unit provided in a node chooses first and second sorting keys out of the virtual paths between the nodes, based on a first and second path information stored in a path information memory unit. Two nodes located at both ends of the route failed due to trouble in the ATM network select a first pair of isolated virtual paths having the first sorting key, which were formerly connected to the failed route, and connect them to a first bypass route. The two nodes then connect in a similar way a second pair of isolated virtual paths both having the second sorting key to a second bypass route.
