摘要:
A mobile station performing a voice communication by using a radio resource, including a determination unit configured to determine whether an inputted packet is in a talk-spurt state or in a silent state; a message generating unit configured to generate a resource release request, when the determination unit determines that the inputted packet is in the silent state; and a transmitting unit configured to transmit the resource release request to a radio base station.

A transmitter apparatus includes: an MAC-SDU receiver section (11) configured to receive an MAC-SDU in an MAC layer from an RLC layer; an MAC-PDU generator section (13) configured to generate an MAC-PDU by multiplexing the received MAC-SDU; and an MAC-PDU transmitter section (14) configured to transmit the generated MAC-PDU, MAC header added in the MAC-PDU includes fixed-length “LI” indicating a size of the MAC-SDU multiplexed into the MAC-PDU, and the RLC layer is configured to transmit the MAC-SDU to the MAC layer, the size of the MAC-SDU being not larger than a maximum size settable by the fixed-length “LI”.
摘要:
According to one aspect of the present invention, a mobile communication system is used for transmission and reception of a data PDU (Protocol Data Unit) in a radio link control (RLC) sublayer between a radio base station and a mobile station. The present system includes a function of feeding back a control PDU to a transmitting side, the control PDU indicating a decoding result of a data PDU at a receiving side. In the present system, in response to an instruction from an upper layer of the RLC sublayer, the transmitting side triggers the receiving side to feed back the control PDU.

A radio communication apparatus including a retransmission control function, includes: determination means configured to determine whether a result of error detection performed in a communication partner side for a first packet after transmitting the first packet to the communication partner is positive acknowledgement or negative acknowledgement; request means configured to request a following second packet from an upper layer when the result of error detection is determined to be positive acknowledgement; and means configured to transmit dummy data to the communication partner as a following second packet when the first packet is the last packet. When the determination determining that the result of error detection is positive acknowledgement is incorrect, a system frame number used when transmitting the dummy data is reported from the communication partner, so that the first packet is retransmitted.
摘要:
A radio controller of a mobile communications system performing broadcasting or multicasting that transmits the same information to multiple cells is disclosed. The radio controller includes a control information comparison part configured to compare the control information of a first one of the cells and the control information of a second one of the cells adjacent to the first one of the cells; and a control information creation part configured to create adjacent cell control information corresponding to the second one of the cells. The control information creation part determines part of the control information of the second one of the cells different from the control information of the first one of the cells as the adjacent cell control information.
摘要:
A mobile communication system for transmitting a plurality of same information to a plurality of cells. The mobile communication system includes a transmission timing determining unit for determining a transmission timing of the same information to each of the cells randomly or in such a manner that transmission timings differ between the cells, and a transmitting unit for transmitting the same information to the cells at the determined transmission timings.

A mobile station (UE) is configured to establish uplink synchronization with a radio base station (eNB). The mobile station (UE) is configured not to return transmission acknowledgment information for downlink data until receiving a command for adjusting uplink transmission timing, when the radio base station (eNB) allocates a radio resource for transmission of the downlink data to the mobile station (UE).
摘要:
A mobile exchange (300) comprising a mobile station information management unit (302) which manages mobile station information including a temporary mobile subscriber identity (TMSI) for identifying the each mobile station uniquely in a first mobile management area and a notification unit which notifies a destination wireless base station (200) to which a mobile station (100) is connected in the first mobile management area of the temporary mobile subscriber identity (TMSI) assigned to the mobile station (100) when the mobile station (100) performing communication in a second mobile management area moves from the second mobile management area to the first mobile management area.
摘要:
A radio access network apparatus includes: a discontinuous reception management unit configured to manage a reception state (a discontinuous reception state or a continuous reception state) for each of one or more mobile stations; a determination and announcement unit configured to determine and announce a correspondence relationship between a discontinuous reception channel and a shared data channel for each mobile station; and a scheduling unit configured to perform scheduling of a downlink shared data channel, wherein, when a paging signal to the mobile station in the discontinuous reception state occurs, the radio access network apparatus transmits the paging signal to the mobile station using the shared data channel determined based on the correspondence relationship.
