Abrégé

In order to increase calculation speed, an exchange control unit (11) holds correspondence information (12) which comprises replica numbers, for identifying each of annealing units (1a0, , 1an), assigned to each of annealing units (1a0, , 1an) and arranged in ascending or descending order of temperature. On the basis of the correspondence information (12), the exchange control unit (11) starts processing by each of the annealing units (1a0, , 1an) in the order of temperature. When processing by two annealing units corresponding to two temperatures has completed, the exchange control unit (12) determines whether or not to exchange the temperatures assigned to the two annealing units without waiting for completion of processing by other annealing units. In the case of performing an exchange, the exchange control unit (11) updates the correspondence information (12), and, on the basis of the updated correspondence information, supplies temperature information representing the temperature to the two annealing units.

Abrégé

The present invention minimizes decreases in calculation speed accompanying increases in circuit scale. When any of the bits in a bit sequence representing the state of the Ising model is inverted, each of bit operation circuits (1a1 to 1aN) calculates an energy change value for the Ising model on the basis of a coefficient indicating the magnitude of the interaction between a self bit in the bit sequence and the inverted bit, then outputs a first signal indicating the advisability of inverting the self bit in accordance with the change value and a second signal indicating the energy change value. A selection circuit unit (2) uses the first signal and the second signal as a basis to select a bit to be inverted in the bit sequence and an energy change value corresponding to said bit, outputs a third signal indicating the selected bit to each of the bit operation circuits (1a1 to 1aN), and outputs a fourth signal indicating the selected energy change value. An energy calculation unit (5) calculates the energy of the Ising model on the basis of the energy change value indicated by the fourth signal.

Abrégé

A video encoding apparatus appends decoding delay and display delay correction information to encoded video data in order to ensure that even when one or more pictures that are later in encoding order than a starting encoded picture in a video data stream to be spliced to a trailing end of another encoded video data stream have been discarded from among pictures contained in the video data stream, the starting encoded picture and its subsequent pictures can be continuously decoded and displayed by a video decoding apparatus. The correction information is calculated based on a decoding interval between each discarded picture and a picture that immediately precedes the discarded picture. The video decoding apparatus corrects the decoding delay and display delay of the starting encoded picture and its subsequent pictures by using the calculated correction information.

Abrégé

A method and terminal equipment for reporting maximum configuration transmission power are disclosed. The method includes that: when a terminal equipment triggers a power headroom report and is distributed an uplink grant for transmitting new data on an uplink shared channel for the present subframe by a base station, wherein the uplink grant can accommodate the power headroom report, the terminal equipment in turn judges whether there is non-adaptive retransmissions on each service cell in the present subframe but the base station does not distribute an uplink grant for transmitting data of uplink shared channel, or the terminal equipment judges whether the base station merely schedules channel state information on each service cell but does not distribute an uplink grant for transmitting data of uplink shared channel; if so, the terminal equipment acquires the maximum configuration transmission power of the corresponding service cell, and reports the acquired maximum configuration transmission power to the base station. Even when the terminal equipment has non-adaptive retransmission or the base station merely schedules channel state information on a service cell, the method can make the terminal equipment report maximum configuration transmission power corresponding to the service cell, thus solving problem existed in the prior art.

Abrégé

An object is to improve data transmission efficiency and surely perform a QoS control. In order to attain the object, a space area assignment section (121) preferentially assigns an area which can be assigned without dividing one RLC-SDU among the space areas of MAC-PDU to the RLC-SDU as the assigned area. An RLC-PDU generation section (124) adds a header of a proper RLC layer to the RLC-SDU outputted from an RLC-SDU buffer section (122) or a retransmission buffer section (123) and generates an RLC-PDU. A wireless resource information acquisition section (131) outputs space area information to the space area assignment section (121) of an RLC process unit that has the highest priority among the RLC process units to which notification of the space area information of the MAC-PDU is not delivered. A MAC-PDU generation section (132) multiplexes the RLC-PDUs according to the assigned area indicated in the notification from the space area assignment section (121) of each of the RLC process units (120-1 to 120- n).

Abrégé

A node device and a program of simple structures autonomously select an appropriate route without imposing a load on a network. In a node device 1 in a communication network, an FID management table 5 stores an FID for unique identification of a frame and the information about a destination node of the frame, and a weighting table 7 stores weighting information about another node as a destination for relay of the frame for each final destination node of the frame. When a frame transmitted to a local node is received, and if the FID of the received frame is stored in the FID management table 5, the data about the destination node associated with the FID is updated. If the FID of the frame received from the frame reception device is not stored in the FID management table 5, the FID management table 5 corresponding to the destination node of the frame is referred to, and another node as a destination for relay of the frame is determined.

Abrégé

A pilot signal transmitting method, which achieves an appropriate cell search without increasing in scale or complicating the mobile station structure, is provided along with a base station, a mobile station and a cellular system to which that method is applied. In a cell-specific pilot signal transmitting method for use in a mobile communication system that comprises a base station and a mobile station wireless communicating with the base station in the cell of a wireless communication area formed by the base station and that can mix and then transmit unicast data and broadcast/multicast data as downstream data from the base station to the mobile station, the difference between the start phase of a cell-specific pilot signal transmitted in a subframe in which the base station transmits the unicast data and the start phase of a cell-specific pilot signal transmitted in the next subframe is equal to the difference between the start phase of a cell-specific pilot signal transmitted in a subframe in which the base station transmits the broadcast/multicast data and the start phase of a cell-specific pilot signal transmitted in the next subframe.

Abrégé

In a multi-carrier cellular system, a second synchronization code (a Walsh code or a GCL series code) mapped on a second synchronization channel is used as a signal for specifying in which cell of the base station a mobile station terminal device itself is. A signal transmitted from the base station to the mobile station terminal device is mapped in a radio frame having two-dimensional extension in frequency and time directions. A synchronization channel on which first and second synchronization channels are mapped is implanted at a plurality of portions in the radio frame. When mapping a certain series number of the second code for specifying a cell or a cell group on the radio frame as the second synchronization channel, phase rotation or circular shift in which one radio frame is one cycle is applied to the second synchronization code. On the receiving side, the head timing of the radio frame is known by knowing the phase rotation angle or the amount of circular shift of the second synchronization code.
