Provided is a mobile communication system which includes a plurality of RAT (Radio Access Technology) and can eliminate the need of a control channel for reporting RAT information so as to prevent congestion or shortage of the control channel capacity. In the mobile communication system, an LTE relay station (30) has a cover area (31) identical to a cover area (21) owned by a WLAN host station (20) and relays/transmits the signal received from an LTE base station (10) to a mobile station (40) in the cover area (31). The LTE relay station (30) adds to the signal received from the LTE base station (10), one of the offsets: a frequency offset, a time offset, and a power offset as information indicating that the mobile station (40) which receives a relay signal from the local station is located in the cover area (21) of WLAN and transmits the signal after offset addition to the mobile station (40) located in the cover area (31) (i.e., the cover area (21)).
摘要:
A communication terminal apparatus that can perform an appropriate system operation at the network side and also can avoid a reduction in throughput and a reduction in system efficiency. In this apparatus, a compressed mode calculating part (124) determines, based on compressed information and slot format information, a slot that is a gap in a frame of a compressed mode. A transmission power control part (125) establishes a transmission power obtained by increasing, by &Dgr; Pilot, the transmission power as designated and set by a TPC command for the slots other than the gap in the frame of the compressed mode. A DPCCH transmission power reporting part (127) outputs, to a channel encoding part (128), a report value indicative of the transmission power obtained by removing the effect of &Dgr; Pilot from the transmission power established by the transmission power control part (125).
摘要:
When a determination section of a reception apparatus determines that a control channel is intended for the reception apparatus, a comparing section of the reception apparatus compares control information transmitted on the control channel with a reception capability of the reception apparatus. A data channel reception section of the reception apparatus receives a data channel when the control information is within the reception capability of the reception apparatus, but does not receive the data channel when the control information exceeds the reception capability of the reception apparatus. When the control information exceeds the reception capability of the reception apparatus, the transmission section does not transmit an ACK signal and a NACK signal with respect to the data channel.

Provided is a base station capable of searching cells of different frequencies without losing a opportunity of data communication by effectively performing SCH data transmission. The base station (100) includes: an encoding unit (101) for encoding SCH data; a modulation unit (102) for modulating the encoded SCH data; a transmission timing setting unit (103) for setting the transmission timing of the SCH data; encoding units (104-1 to 104-N) for encoding user data (#1 to #N), modulation units (105-1 to 105-N) for modulating the encoded user data (#1 to #N); 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 transmission timing setting unit (103) sets the transmission timing of the SCH data so that, for example, the SCH data transmission cycle and the frame cycle are relatively prime, i.e., the maximum common multiple of them is 1.

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.
摘要:
A radio base station apparatus wherein the consumption of transmission power resources in a high-rate packet transmission can be suppressed. In the apparatus, a scheduling part (31) limits the candidates of an upstream line packet transmission rate to part of a plurality of transmission rates indicated by transmission rate combination information, selects an upstream line packet transmission rate from among the limited transmission rate candidates, and creates scheduling result information including transmission rate information indicative of the selected transmission rate. The scheduling result information is wireless transmitted from an antenna (108) to a communication terminal that is permitted to transmit upstream line packets.

A work piece pickup method is for sucking and holding a work piece attached on an adhesive sheet by means of a suction collet that is disposed above the work piece attached on the adhesive sheet in such a way as to be movable up and down for sucking and holding the work piece and a suction member that is disposed below the adhesive sheet in such a way as to be movable up and down so as to detach and transfer the work piece. The method comprises a sheet suction process for sucking and holding a lower surface of the adhesive sheet corresponding to the work piece by the suction member, and a work piece suction process for sucking and holding the work piece by the suction collet under a state in which the suction collet and the work piece are in a positional relationship spaced from each other so as to detach the work piece. A pickup apparatus and a mounting machine operate in accordance with the above method.
摘要:
The present invention relates to a hybrid automatic repeat request (HARQ) method for transmitting data packets from a transmitting entity to a receiving entity via a data channel. Further, the present invention is related to mobile stations, base stations, radio network controllers and communication systems performing in the HARQ method. To overcome problems resulting from asynchronous retransmissions, the present invention provides a HARQ method sending retransmissions synchronous. According to the method, a feedback message is 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 said feedback message. The receiving entity soft combines the retransmission data packet with the previously received data packet.
