摘要:
Mobile stations, base stations, radio network controllers and communication systems perform according to the hybrid automatic repeat request (HARQ) protocol for transmitting data packets from a transmitting entity to a receiving entity via a data channel. A HARQ method sending synchronous retransmissions involves a feedback message received from the receiving entity at the transmitting entity and, in case the feedback message indicates that the data packet has not been received successfully, a retransmission data packet is transmitted to the receiving entity after a predetermined time span upon having received the feedback message. The receiving entity soft combines the retransmission data packet with the previously received data packet.

Provided is a base station capable of searching cells of different frequencies without losing a chance of data communication by effectively performing SCH data communication. The base station (100) includes: an encoding unit (101) for encoding SCH data; a modulation unit (102) for modulating the encoded SCH data; encoding units (103-1 to 103-N) for encoding user data (#1 to #N), modulation units (104-1 to 104-N) for modulating the encoded user data (#1 to #N); a frame format setting unit (105) for setting a frame format of each frame; and an IFFT unit (106) for mapping the SCH data and the user data (#1 to #N) to sub carriers (#1 to #K) and performing IFFT to generate an OFDM symbol. The frame format setting unit (105) changes the data communication sub frame for each frame so as to change the position of the data communication section within a frame for each frame.

In order to perform diversity reception efficiently without increasing the scale of the apparatus, when the total number of simultaneously connected cells has reached N cells including an HSDPA serving cell a control section 104 keeps a switch 103 connecting a buffer 102-1 to a despreading section 105, and conversely, when the total number of simultaneously connected cells has not reached N cells including an HSDPA serving cell, after completion of despreading and delay profile generation for the simultaneously connected cells performed for the received signal of an antenna #1, control section 104 switches switch 103 to connect a buffer 102-2 to despreading section 105. By means of this switching control, diversity reception is performed for an HSDPA serving cell only when the total number of simultaneously connected cells has not reached N and there are free resources.

A display device includes an electron-emitting device which is a laminate of an insulating layer and a pair of opposing electrodes formed on a planar substrate. A portion of the insulating layer is between the electrodes and contains fine particles of an electron emitting substance, that portion acting as an electron emitting region. Electrons are emitted from the electron emission region by applying a voltage to the electrodes, thereby stimulating a phosphorous to emit light.

A digital signal processor includes a functional unit configured to execute instructions. The functional unit determines a first minimum data of a first data and a second data, in parallel with a determination of a second minimum data of a third data and a fourth data. The functional unit outputs processed data including the first minimum data and the second minimum data. Each bit length of the first minimum data and the second minimum data is equal to n bits in length. A bit length of the processed data is equal to 2 n bits in length.

An image-forming device having, in an envelope, an electron-emitting element, an image-forming member for forming an image by irradiation of an electron beam emitted from the electron-emitting element, and an electroconductive supporting member for supporting the envelope. The potential of the supporting member is controlled to not be higher than the maximum potential applied to the electron-emitting element. The electron-emitting element and the image-forming member can be placed in juxtaposition on the same substrate, an electro-conductive substrate can be additionally provided in opposition to the face of the substrate, and the supporting member can be connected electrically to one of the electrodes and also to the electro-conductive substrate.

A display device consists of an electron-emitting device which is a laminate of an insulating layer and a pair of opposing electrodes formed on a planar substrate. A portion of the insulating layer is between the electrodes and a portion containing an electron emitting region in between one electrode and the substrate. Electrons are emitted from the electron emission region by a voltage to the electrodes, thereby stimulating a phosphorous to emitting light.

A wireless communication apparatus for performing a different carrier measurement without lowering throughput is disclosed. In this apparatus, a packet continuation determining section (121) observes user packet data and determines whether packets addressed to the wireless communication apparatus are continuously received or paused; a different carrier measurement suppressing section (122) generates a signal to allow the different carrier measurement when the determination result in the packet continuation determining section (121) indicates that packets are paused and does not generate the signal to allow the different carrier measurement when the determination result in the packet continuation determining section (121) indicates that packets are continuing. When the different carrier measurement is allowed, the different carrier reception timing setting section (112) notifies the timing of switching the carrier to a carrier switch controlling section (113) and a carrier reception quality measuring section (110), and at this timing, the carrier switch controlling section (113) controls the carrier switch of the RF receiving section (102) and the carrier reception quality measuring section (110) measures the reception quality of the switched carrier.

A data transfer system capable of lightening the load on a server and reducing the amount of data carried over a network. A search/registration unit of the server determines whether or not shape data in graphics information created by a three-dimensional application is registered in shape cache information and, if not registered, registers the shape data. If the shape data is registered, a data transfer unit replaces the shape data with designation information specifying the corresponding data in the shape cache information to generate graphics differential information, and transmits the generated information to a client. A registration unit of the client registers new shape data in shape cache information in accordance with the graphics differential information. A data restoration unit searches the shape cache information based on the designation information to extract the corresponding shape data, and replaces the designation information with the shape data to restore the graphics information.
