摘要： 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.

摘要： A control method in a mobile communication system with a buffer unit for temporarily storing packet data to be sent, includes dropping the packet data stored in the buffer unit before sending when a drop timer corresponding to the packet data before sending reaches a given value or when a drop condition required by a drop mechanism accompanying the buffer unit is satisfied, and dropping the packet data stored in the buffer unit after sending when a drop timer corresponding to the packet data after sending reaches a given value.

摘要： Efficiency in data transmission performed in the case of a contention based radio resource being set is improved. A radio communication apparatus (2) selectively performs one of a first transmission method using for data transmission a radio resource which is assigned by a radio communication apparatus (1) and which can be used on a contention basis by a plurality of radio communication apparatus (2 and 3) and a second transmission method involving random access. Alternatively, the radio communication apparatus (2) selectively performs one of the first transmission method and a third transmission method involving a request made to the radio communication apparatus (1) to assign a radio resource for data transmission.
