摘要:
The mobile communication network system having a plurality of mobile communication systems each including a base station performing wireless communications with a mobile station, comprises a storage unit storing location information of the mobile station, an acquisition unit acquiring, when receiving a location registering request from the mobile station, a communication-enabled mobile communication system in the mobile station as a sender of the location registering request, a specifying unit specifying a base station existing within the acquired communication-enabled mobile communication system and existing in the periphery of the base station receiving the location registering request, and a control unit storing the storage unit with information of the base station receiving the location registering request and information of the specified base station as location information about the sender mobile station of the location registering request.
摘要:
The radio communication system, comprises: a base station; and a plurality of terminals which perform reservation request for radio resources necessary for data transmission to said base station at random, wherein each of the plurality of terminals are allocated with individualized radio resources for reservation request necessary for the terminal to perform the reservation request to the base station. As a result, the occurrence of collision of reservation requests is eliminated.
摘要:
A scheduling method for transmitting an uplink signal from a mobile station to a base station comprises transmitting the uplink signal in a first scheduling mode in which the mobile station can transmit the uplink data without permission of the base station if an uplink communication state between the base station and the mobile station is higher than or equal to a predetermined quality; and transmitting the uplink signal in a second scheduling mode in which the permission is necessary for the mobile station transmitting the uplink data if the uplink communication state is lower than the predetermined quality.
摘要:
The present method adds uplink data to a transmission request sent to the base station from the mobile station for obtaining permission for data transmission, or to a channel establishment request sent from the mobile station to the base station for establishing a channel in order to send the transmission request therethrough. This makes it possible to suppress delay caused by negotiation prior to actual uplink data transmission as much as possible, thereby realizing efficient uplink data transmission, that is, improved throughput of uplink communication.

摘要:
A mobile communication system in which, when transmission is performed from a base station to a terminal device, a modulation scheme is designated, from among at least two modulation schemes with different modulation levels, on the basis of reception quality at the terminal to perform transmission from the base station. The system includes a base station transmitting at a first transmission power using a frequency designed for, in a channel allocation scheme of the system, not causing interference with an adjacent base station and using a first modulation scheme, and a second channel transmitting at a second transmission power lower than the first transmission power, and when the base station uses the second channel, a second modulation scheme having a lower modulation level than the first modulation scheme is designated, and communication is performed.
摘要:
A mobile communication terminal (UE) comprises: a transmitting unit (213, 211) which transmits a signal via a radio resource allocated to the mobile communication terminal (UE) for the transmission of a prescribed control signal; and a signal selector unit (214) which, when upstream traffic occurs, selects a reservation request signal as the signal to be transmitted via the allocated radio resource wherein, when the mobile communication terminal (UE) is in a standby state, the reservation request signal is transmitted from the mobile communication terminal (UE) to the base station (BS) by using the radio resource allocated to the mobile communication terminal (UE) for the transmission of the prescribed control information.
摘要:
A transmission controlling method for a wireless communication system wherein a plurality of data blocks can be transmitted from a sender apparatus having a plurality of sending antennas to a receiver apparatus, the transmission controlling method includes on the sender apparatus, sending process information which is not competitive between data blocks to the receiver apparatus with a control channel; and sending the data block to the receiver apparatus; and on the receiver apparatus, receiving the data block and the process information from the sender apparatus.
摘要:
A transmission controlling method for a wireless communication system wherein a plurality of data blocks can be transmitted from a sender apparatus having a plurality of sending antennas to a receiver apparatus, the transmission controlling method including on the sender apparatus, sending process information which prevent plurality of data blocks from competing to the receiver apparatus with a control channel; and on the receiver apparatus, combining, based on the process information, the data block received already and a re-sent data block.
摘要:
In a wireless communication system, a sender apparatus sends a data block, for each of a plurality of stream data, with data block identification information, which does not conflict between stream data, annexed, and a reception apparatus performs a re-sending synthesis process for a data block received already and a re-sending data block to which the same data block identification information is individually annexed based on the data block identification information annexed to the received data block. Consequently, also in a case wherein the number of transmission streams between the sender apparatus and the reception apparatus is varied (reduced), the matching property of the data block which is a re-sending synthesis target can be maintained and communication can be continued normally.
