摘要:
In a mobile communication system, an RRM measurement set is set as a collection of cells to become targets on which a UE performs a process of detecting whether or not radio communication is allowed. Among the cells in the RRM measurement set, a CoMP measurement set is set as a collection of cells to become candidates on which the UE performs a process of detecting whether or not coordinated communication (CoMP communication) is allowed. Among the cells of the CoMP measurement set, a CoMP active set is set as a collection of cells to become targets on which the UE performs the process of detecting whether or not CoMP communication is allowed.

A mobile communication system includes a movable user equipment device, a plurality of base station devices configured to perform radio communication with the user equipment device, and a relay device movably configured to relay radio communications between the user equipment device and the base station devices. In a handover process of switching a base station device to be connected with the relay device from a base station device being a moving source to a base station device being a moving destination along with moving of the relay device, the base station device being a moving source selects the base station device being a moving destination from base station devices other than a base station device that does not have a function supporting the relay device, and performs the handover process such that the relay device is connected to the selected base station device.

A terminal transmits a request for a resource assignment to a base station, and acquires a value of a resource for data transmission. The terminal does not transmit the new data to the base station when the resource for data transmission does not exist, and transmits the new data to the base station otherwise, after acquiring the value. The terminal autonomously transmits, when the new data is transmitted to the base station and a NAK signal is received from the base station, the retransmission data to the base station without sending a transmission request to the base station for resources to transmit the retransmission data.

A method transmits data from a user equipment (UE) including a transceiver having a set of available antennas. The method selects a subset of antennas from the set of available antennas; and transmits the data by the transceiver using the subset of antennas. The selecting subset of antennas includes transmitting sounding reference signals (SRSs) according to specified times, frequencies, and antennas; and receiving, in response to the transmitting the SRSs, information indicative of a selection of the subset of antennas.

A mobile terminal judges whether or not the mobile terminal is able to make a transition to a DTX period during Active, and, when judging that the mobile terminal is able to make a transition to a DTX period during Active, notifies a base station to that effect. If the base station judges that the mobile terminal is able to make a transition to a DRX period during Active when triggered by the notification from the mobile terminal, the base station temporarily stops supply of electric power to the data transmission processing units and the data reception processing units of the mobile terminal.

An electric wire shaping apparatus includes a pair of male and female shaping dies and a pressing mechanism. Each of the male and female shaping dies has a shaping surface that includes a plurality of straight parts and a plurality of bent parts. The pressing mechanism moves one of the male and female shaping dies toward the other, thereby pressing a turn portion of an electric wire between the shaping surfaces of the male and female shaping dies in a width-wise direction of the turn portion. Furthermore, the male and female shaping dies are so configured that when they are located closest to each other, a gap W2 between a corresponding pair of the bent parts of the shaping surfaces of the male and female shaping dies is different in size from a gap W1 between a corresponding pair of the straight parts of the shaping surfaces.

A communication apparatus for use in a radio communication system having plural communication channels on a frequency domain. The communication apparatus includes an ACK/NACK generating unit that generates an ACK or a NACK based on a result of decoding of a received signal; a quality-information organizing unit that accumulates a channel quality obtained by a predetermined measuring process, of each of the communication channels, and that outputs a CQI in timing of an ACK or an NACK output by the ACK/NACK generating unit; and a transmitting unit that receives a CQI from the quality-information organizing unit and receives an ACK or an NACK from the ACK/NACK generating unit, and that transmits the CQI and the ACK or the NACK through the same communication channel.
摘要:
Since OFDM (Orthogonal Frequency Division Multiplexing), which is a downlink access scheme used for an LTE (Long Term Evolution) communication system, is weak at interference, it is preferable that the number of base stations for transmitting the same E-MBMS (Evolved Multimedia Broadcast Multicast Service) data be not excessive.Thus, the mobile terminal performs: processing of obtaining measurement quality values by measuring reception quality of each base station; processing of deciding on whether the measurement quality value of a serving base station exceeds a certain receiving level; processing of adding measurement quality values of other base stations to the measurement quality value of the serving base station until the sum exceeds the certain receiving level; and processing of notifying the serving base station of the serving base station and other base stations as candidates for an active set for E-MBMS. This makes it possible to select as the active set for E-MBMS an appropriate number of base stations that make it compatible to maintain good reception quality and to prevent interference.

摘要:
A printed circuit board on which are laid out detection windings and an excitation magnetic flux detection winding formed of conductor patterns is disposed so as to be spaced a predetermined gap quantity from a binary cyclic random number sequence code plate which is rotatably disposed. A U-shaped exciting core on which an excitation winding is wound is disposed on the back surface side of the printed circuit board. The detection windings detect and output, as voltage values, reluctance changes as which excitation magnetic fluxes generated from the excitation winding fluctuate between this excitation winding and the concave/convex portion of the binary cyclic random number sequence code plate. Reduction of precision due to interferences between the excitation magnetic fluxes for detecting an absolute code and other excitation magnetic flux is thereby prevented.
摘要:
A terminal transmits a request for a resource assignment to a base station, and acquires an initial value of a resource for data transmission that can be reduced with time. The terminal does not transmit the new data to the base station when the resource for data transmission is not remained, and transmits the new data to the base station otherwise, after acquiring the initial value. The terminal transmits, when the new data is transmitted to the base station and a NAK signal is received from the base station, the retransmission data to the base station regardless of a state of the resource for data transmission.
