摘要： A retransmission control method has a physical control channel transmission step wherein a transmission side apparatus (10) transmits a new data specifier updated upon new packet transmission and a retransmission sequence number indicating whether transmission is the first transmission or retransmission, through a physical control channel related to a physical data channel. The retransmission control method also has a delivery confirmation information transmitting step wherein the receiving side apparatus (10) transmits delivery confirmation information to a packet received through the physical data channel, based on a new data specifier and the retransmission sequence number received through the physical control channel.

摘要： A radio base station (eNB) is configured to start the transmitting-side timer and a Polling timer which is set to expire earlier than the transmitting-side, upon transmission of a last piece of downlink data accumulated in a transmission buffer to the mobile station. When the Polling timer expires, the radio base station (eNB) notifies the mobile station (UE) of the expiration, and restarts the transmitting-side timer, and the mobile station (UE) restarts a receiving-side timer in response to the notification.

摘要： In a retransmission-request transmitting method, the receiving side apparatus activates a reordering timer, when receiving a first packet before receiving an unreceived packet with a sequence number smaller than a sequence number of the first packet; triggers transmission of a retransmission request for the unreceived packet, when having not received the unreceived packet by the time of expiration of the reordering timer activated in response to the receipt of the first packet; and stops and reactivates the reordering timer activated in response to the receipt of the first packet, when a value of the sequence number of the first packet falls out of a range of the receiving side window as a result of changing the upper limit value and the lower limit value in accordance with a sequence number of a second packet received from the transmitting side apparatus.
