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 |
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 |
20100165933 | CHANNEL ALLOCATION NOTIFYING METHOD, COMMUNICATION METHOD, AND COMMUNICATION APPARATUS - The number of communication channels necessary for communication with a terminal is calculated by using type and volume of data to be transmitted (Step S | 07-01-2010 |
20100167772 | COMMUNICATION METHOD, WIRELESS COMMUNICATION SYSTEM, TRANSMITTER, AND RECEIVER - In a wireless communication system where data transmission is performed between a base station and terminals, the base station individually generates, for each terminal, a bit map indicative of scheduling resource numbers to be allocated to terminals to which Localized transmission is applied, based on a resource-number mapping rule defined by providing individual resource block numbers to all resource blocks, taking resource block numbers of resource blocks for Distributed transmission as fixed values, and providing individual scheduling resource numbers to remaining resource blocks for Localized transmission except the resource blocks for Distributed transmission for each of scheduling resources corresponding to the number of aggregation. | 07-01-2010 |
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 |

20120202547 | CHANNEL ALLOCATION NOTIFYING METHOD, COMMUNICATION METHOD, AND COMMUNICATION APPARATUS - The number of communication channels necessary for communication with a terminal is calculated by using type and volume of data to be transmitted. When calculated number of communication channels is one, a single communication channel is allocated based on quality information of a communication line to the terminal and, when calculated number of communication channels is more than one, then more than one communication channels are allocated based on the quality information. Allocation information used for notifying of allocated communication channels is generated based on virtual channels, which are defined in advance as channel units having a combination of a plurality of consecutive communication channels, and the allocation information is transmitted to the terminal. | 08-09-2012 |

20130023300 | BASE STATION AND TRANSFER CONTROL METHOD - A base station that gives a transmission opportunity to a mobile station present in an area of the base station in a unit of a predetermined time length, and controls a transfer rate of an uplink by specifying power of a data transfer channel by a power ratio to a specific channel for which predetermined power control is executed. The base station includes a power measurement unit a reception signal, and an EUL control that measures power of each channel constituting unit that calculates a free resource based on reception power of each channel and determines a power ratio between a data transfer channel through which the mobile station performs transmission and the specific channel, based on a size of data received most recently from the mobile station, the free resource, required communication quality predetermined for each size of reception data, and most recent reception power of the specific channel. | 01-24-2013 |
20130242857 | RELAY DEVICE AND AUXILIARY RELAY DEVICE - A relay device that relays a signal in which a plurality of signals having respectively different frequencies are multiplexed between a first communication device on a transmission side and a second communication device on a reception side. The relay device includes: a demultiplexing unit; a relay-method decision unit; a signal regeneration unit; and a multiplexing unit. The demultiplexing unit demultiplexes a signal received from the first communication device to a plurality of frequencies. The relay-method decision unit decides which relay method is performed on a signal having been demultiplexed by the demultiplexing unit. The signal regeneration unit performs demodulation, decoding, coding, and modulation on a signal decided to undergo regenerative relay by the relay-method decision unit. The multiplexing unit multiplexes a signal decided to undergo transparent relay by the relay-method decision unit and a signal regenerated by the signal regeneration unit. | 09-19-2013 |
