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： 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.

摘要： A radio base station (eNB) starts a transmitting-side timer upon transmission of downlink data; and changes a reception cycle of downlink data in a mobile station (UE), when transmitting no downlink data during a period from start to expiration of the transmitting-side timer. The mobile station (UE) starts a receiving-side timer upon receipt of downlink data transmitted; and changes a reception cycle of downlink data in the mobile station (UE), when receiving no downlink data during a period from start to expiration of the receiving-side timer.

摘要： One object of the present invention is to provide a simple layer 2 protocol that makes it possible to adaptively retransmit data by the RLC layer according to the variation of radio channel conditions without increasing the number of PDU headers. A disclosed radio communication method includes the steps of determining whether a unit data block is to be transmitted for the first time by the RLC layer or to be retransmitted; if the unit data block is to be retransmitted, determining whether it is possible to retransmit the unit data block with a transmission time interval used for the first transmission; and if it is not possible to retransmit the unit data block with the transmission time interval used for the first transmission, setting a transmission time interval longer than the transmission time interval used for the first transmission for a downlink channel and/or an uplink channel.

摘要： A transmitter apparatus includes an MAC-PDU generator section configured to generate an MAC-PDU by multiplexing information elements in an MAC layer and a first data unit transmitter section configured to transmit the generated MAC-PDU. Each of the information elements is any of an MAC-SDU received from an RLC layer, an MAC control block and Padding. The MAC-PDU generator section is configured to add an MAC header to the first data unit. The MAC header includes a C/T identifying a type of each of the information elements multiplexed into the MAC-PDU and an LI indicating a size of each of the information elements.
