Patent application number | Description | Published |
20090175183 | DATA COMMUNICATION METHOD AND MOBILE COMMUNICATION SYSTEM - 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. | 07-09-2009 |
20090180414 | Mobile Communication System and Mobile Terminal - 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. | 07-16-2009 |
20090204866 | DATA TRANSMISSION CONTROL METHOD AND TRANSMITTER APPARATUS - A data-transmission control method is implemented when transmitting data after dividing the data into a plurality of blocks and performing error correction when performing data transmission. The method includes obtaining additional information indicating a result of error correction process of received data and a result of data transmission (ACK/NACK) from a reception station, and deciding a data length of data to be retransmitted when NACK is obtained as the result of data transmission so that a rate of occurrence of transmission errors upon retransmission is minimized, based on a number of blocks in which error correction has failed indicated by the additional information. | 08-13-2009 |
20100061285 | DATA COMMUNICATIONS METHOD AND MOBILE COMMUNICATIONS SYSTEM - In a communications system including a base station capable of altering a frequency bandwidth which is used for transmitting broadcast data for providing point-to-multipoint broadcasting communications service and which is used for transmitting individual communications data for providing point-to-point individual communications service, and a mobile terminal capable of altering a receivable bandwidth which is used for receiving at least the broadcast data and the individual communications data transmitted from the base station, decision processing of making a decision as to whether the mobile terminal can receive reception-desired content it desires to receive among contents provided by the broadcasting communications service is executed in accordance with a frequency occupying bandwidth used for transmitting the reception-desired content. Thus, the mobile terminal becomes able to make a decision as to whether it can receive particular E-MBMS content considering its own UE position. | 03-11-2010 |
20100322187 | COMMUNICATION SYSTEM, BASE STATION, AND MOBILE STATION - A base station divides a packet into a plurality of wireless transfer blocks, determines a priority of a wireless transfer block based on a delivery acknowledged amount accumulated value, allocates wireless resources to the wireless transfer blocks based on determined priority, and transmits generated wireless transfer blocks by using allocated wireless resources. A mobile station transmits a delivery acknowledgement to the base station when the wireless transfer block is properly received and a re-transmission request when the wireless transfer block is not properly received, and reproduces the packet from received wireless transfer blocks. | 12-23-2010 |
20110090836 | DATA COMMUNICATION METHOD AND MOBILE COMMUNICATION SYSTEM - 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. | 04-21-2011 |
20120099437 | TERMINAL SWITCHING METHOD, BASE STATION, AND COMMUNICATION SYSTEM - A terminal switching method for switching terminals, in a communication system in which HARQ processing is performed, to which a base station grants a transmission permission, from a terminal A to a terminal B includes notifying the terminal B of aborting of the transmission permission, setting a time point at which an HARQ process whose state of the HARQ processing is a retransmission waiting state with the terminal A is performed as a virtual starting point, setting a retransmission waiting window having a predetermined window length with the virtual starting point being regarded as its starting point, and notifying the terminal B of the transmission permission when there is no HARQ process having the retransmission waiting state with the terminal A, wherein the virtual starting point setting and the window setting are repeated until there is no HARQ process having the retransmission waiting state with the terminal A. | 04-26-2012 |
20120170485 | MOBILE COMMUNICATIONS SYSTEM AND MOBILE TERMINAL - A mobile terminal | 07-05-2012 |
20140056201 | DATA COMMUNICATIONS METHOD AND MOBILE COMMUNICATIONS SYSTEM - In a communications system including a base station capable of altering a frequency bandwidth which is used for transmitting broadcast data for providing point-to-multipoint broadcasting communications service and which is used for transmitting individual communications data for providing point-to-point individual communications service, and a mobile terminal capable of altering a receivable bandwidth which is used for receiving at least the broadcast data and the individual communications data transmitted from the base station, decision processing of making a decision as to whether the mobile terminal can receive reception-desired content it desires to receive among contents provided by the broadcasting communications service is executed in accordance with a frequency occupying bandwidth used for transmitting the reception-desired content.
