摘要:
In a transmission diversity control method in which a request to start or stop transmission diversity is issued by a reception station to a transmission station having a transmission diversity function, the reception station is provided with an equalizer to reduce multipath interference on the basis of a signal correlation, a transmission diversity start request is issued from the reception station to the transmission station when an effect generated by the equalizer is small, and a transmission diversity stop request is issued from the reception station to the transmission station when the effect generated by the equalizer is large.

A storage battery has at least battery banks, switching units, a charging terminal, a discharging terminal and a battery management unit. The battery banks form a bank structure. Each switching unit electrically connects a group of the battery banks with either the charging terminal or the discharging terminal, and disconnects the group of the battery banks from the charging terminal or the discharging terminal. The battery management unit instructs the switching units to electrically and simultaneously connect one or more battery banks to the charging terminal during charging, and to electrically and simultaneously connect one or more battery banks to the discharging terminal during discharging.

An encoding apparatus includes a dividing unit that divides an input signal bit sequence into data blocks and an encoding unit that applies error correction encoding to the data blocks to generate code blocks decodable by repetitive decoding calculations for estimating the reliability of signal bits for a plurality of times and a generation unit that generates redundant bits by performing bit calculations between data blocks of each set combining the divided data blocks; and an output unit that outputs the generated code blocks and redundant bits.

When transmitting retransmission data, MCS information of a control channel for when communicating the new data is replaced with retransmission control information and the control channel is transmitted. When receiving retransmission data, the control channel is received to obtain the retransmission control information, the replaced MCS information is estimated from the control channel received at the time of communication of new data, and a reception process of retransmission data is controlled using the estimated MCS information and the retransmission control information.

A cubic metric calculator performs a calculation of a time average of power of the amplitude of a transmission signal when a cubic metric value is calculated as a product-sum operation between a transmission power-dependent term including an amplitude value depending on the transmission power of a transmission signal and a time average term including only a modulation parameter not depending on the transmission power of the transmission signal. When the transmission signal is transmitted, the operator inputs the amplitude value to calculate the transmission power-dependent term, reads the value of the time average term from coefficient memory, and performs the product-sum operation using an operation result of the transmission power-dependent term and the read value of the time average term, thereby calculating a time average of the power of the amplitude of the transmission signal.

A receiving apparatus includes a converting unit that multiplies first and second reception signal points for the respective first and second reception signals by a matrix and outputs resulting converted first and second reception signal points; a number-of-candidates determining unit that determines a number of candidates for at least first transmission-signal candidate points, based on a reception quality for the first and second reception signals; and an estimating unit that selects, based on the converted first and second reception signal points, the first transmission-signal candidate points and second transmission-signal candidate points, the number of first transmission-signal candidate points corresponding to the determined number of candidates, and that estimates, as the first and second transmission signals, the first and second transmission-signal candidate points with which distances between the selected first and second transmission-signal candidate points and the corresponding converted first and second reception signal points are smallest.

A control method in a mobile communication system comprising an antenna group including a plurality of antennas each transmitting different antenna identification information includes assigning identification information that allows distinction among antennas included in an antenna subgroup to each antenna included in the antenna subgroup, the antenna subgroup being part of the antenna group; notifying the correspondence between each antenna included in the antenna subgroup and the identification information to a mobile station; and the mobile station using the identification information to distinguish among the antennas included in the antenna subgroup based on the notified correspondence.
摘要:
A method of signaling to enable tethering among wireless devices may include receiving, at a master wireless device, assignment information from a wireless communication access point. The assignment information may indicate that the master wireless device is designated as a hotspot for a slave wireless device. The method also may include determining an availability of an open frequency band for wireless communications, communicating an enabling signal to the slave wireless and receiving a confirmation of receipt of the enabling signal. Further, the method may include determining an allocation of a wireless communication resource over the open frequency band for the master wireless device to act as the hotspot for the slave wireless device. The allocation may be based on the confirmation of receipt of the enabling signal and on a parameter requirement associated with the master wireless device acting as the hotspot for the slave wireless device.

An electric power supply system has, as multiple storage units, an output type battery of high output and small capacity and a capacity type battery of low output and large capacity. The charge-discharge electric power of each of the storage units is controlled by a controller according to a charge-discharge schedule for a prediction period. Based on a predicted power consumption schedule, a predicted power generation schedule, and a charge-discharge characteristic of each of the storage units, the controller determines a charge-discharge schedule with regards to an optimal evaluation index, and controls the storage units in accordance with the charge-discharge schedule.

Testing of a test article based on a color development state of a test area is achieved in an easy manner. A sample is deposited on a spreading layer of a test piece, and the test piece is loaded in a loading port of a chromatographic analysis apparatus. After a preset time has elapsed, color development states of the test area and a control area in an observation window are read as an image. A preprocessing unit applies preprocessing to the image, and then, spatial frequency components of the image are calculated. Then, pattern information is generated based on the spatial frequency components, and the pattern information is displayed on an information output unit.
