摘要:
In an intermittent communication system where an intermittent communication can be made between a base station and a mobile station, a transmitting unit of the mobile station transmits a request to start a normal communication after stopping an intermittent communication at timing different from the intermittent communication if a handover is determined to be required. A transiting unit transits from the intermittent communication to the normal communication after the transmitting unit transmits the request. A handover performing unit performs a handover upon completion of transition to the normal communication by the transiting unit.

A communication apparatus that performs receiving processing of data transmitted at timings of a predetermined interval, the communication apparatus having a transmitting unit configured to transmit a signal (ACK) indicating that data is successfully received when the data transmitted at an M th predetermined interval is successfully received, and a control unit configured to suspend the above receiving processing or conduct other receiving processing until the M+1 th interval after the transmission of the signal. In this way, unnecessary retransmissions are reduced whilst intermittent reception is being performed.

A modulation mapper (1003) selects respective data blocks (DBs) hierarchically and sequentially in descending order of a transmission power ratio; locates, from a resource element group, unused REs to which modulation symbols can be allocated; and decides the allocation of modulation symbols in the REs. A channel resource element mapper (1004) performs the mapping of modulation symbols of the respective DBs to the REs on the basis for the decided allocation. A complex-value transmission signal is generated from the group of REs.

A communication system comprises a radio transmission apparatus for retransmitting data and a radio reception apparatus for receiving the retransmitted data. The radio transmission apparatus is configured to add a sequential number, first information and second information to each of a plurality of divided data which is generated by dividing the data to be retransmitted, and to transmit the plurality of divided data including the sequential number, the first information and the second information to the radio reception apparatus. The sequential number identifies the data to be retransmitted, the first information indicates the position of each of the plurality of divided data in the data to be retransmitted, and the second information indicates whether each of the plurality of the divided data is last data in the plurality of the divided data.
摘要:
In a method for an intermittent communication system where an intermittent communication can be made between a base station apparatus and a mobile station apparatus, the mobile station apparatus changes a period of the intermittent communication and transmits a signal in the changed period.
