摘要:
A radio communication system includes a radio network controller, base stations and mobile stations. The mobile station includes a response signal transmitter which is configured to transmit a response signal including a group ID identifying a multicast group A to a base station. The response signal responds to a control signal for the multicast group A which the mobile station is joining in. The base station includes a response signal transmitter configured to transmit at least one response signal to the radio network controller. The response signal is selected from at least one response signal transmitted from the mobile station joining in the same multicast group A.

The object of the present invention is to provide a base station 10, a mobile station 11 and a radio network controller 50 which can reduce the load on the radio network controller 50 during multicast communication. The base station 10 supporting multicast communication comprises a response signal relay 10b configured to transfer response signals transmitted from a plurality of mobile stations 11, 12, 21, 41, 42 to a radio network controller 50. The response signals respond to a control signal for a multicast group. The response signal relay 10b transfers only a predetermined number of response signals to the radio network controller 50. Any following response signals are retained.

The object of the present invention is provide a mobile communication system which can reduce power consumption of a mobile station without increasing the number of times the data signals which are to be received by the mobile station are retransmitted. The base station 10 comprises a signal transmitter 11 configured to transmit the data signal a to the mobile station 30 within a predetermined period, and transmit each of retransmission signals a1 to a3 of the data signal a, in a form different from that of the data signal a, from the base station 10 to the mobile station 30 within the predetermined period A. The mobile station 30 comprises a receiving processor 31 configured to carry out receiving processing of the data signal a or the retransmission signal a1 within the predetermined period A; a communication quality detector 32 configured to detect a communication quality of the data signal a or the retransmission signal a1; and a reception processing method decider 33 configured to decide a reception processing method for the data signal a or the retransmission signal a1 in the predetermined period A, in accordance with the communication quality detection result.

A radio network controller 30 includes a selection decision unit 31 for deciding whether or not the selection of cells to be used by mobile stations after data reception is to be performed, and a mobile station controller 32 for instructing the mobile stations to select cells to use after the data reception according to a result of a decision by the selection decision unit 31.
摘要:
An acquiring unit (60) of a reception device acquires, from a transmission device, a notification of re-establishment of data in a lower layer. A notifying/instructing unit (70) of the reception device notifies, to the transmission device, a sequence number in a higher layer of data which is desired to be received. An RLC processing unit (40) of the transmission device acquires, from the reception device, a sequence number in a higher layer of data which is desired to be received; and performs the re-establishment from the data having the sequence number.

摘要:
A notification equipment comprises a transmission data determination unit configured to determine whether transmission data to be transmitted to a terminal equipment is first transmission data or repeated transmission data, an instruction data generator configured to generate identification instruction data indicating that the transmission data is the first transmission data or the repeated transmission data based on a transmission data determination result by the transmission data determination unit, and an instruction data transmitter configured to transmit the identification instruction data to the terminal equipment.
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.
