Abstract: A method and an apparatus for retransmitting two layer ARQ for packets improve efficiency of a wireless transmission resource by transmitting packets with a small size together. Whether upper layer data received in the packet data unit transmitted with the polling information induces an upper layer response message is checked(515). If the upper layer response message is induced, the packet data unit including the polling information is transmitted to a lower layer(525). The polling information indicates to transmit a reception report with the upper layer packet generated after waiting for a constant time after receiving the packet.

Abstract: A power setting system and a method therefor are provided to enable discontinuous uplink packet transmission in the next generation mobile communication system. A terminal triggers uplink packet transmission(401). The terminal checks whether the uplink packet transmission occurs within the previous window based on the uplink packet transmission point of time(411). The terminal sets power for the uplink packet transmission as the result of [Power Data(Current transmission) = Power Ref(Last transmission) + Delta Grant](421).

Abstract: A method and an apparatus for reporting a buffer state in a mobile communication system are provided to simplify a buffer state report message transmission procedure by allowing a terminal to transmit a buffer state report message after transmission resources are allocated although a buffer state report message transmission period arrives in a state that transmission resources have not been allocated. A transmission buffer(805) stores data to be transmitted to an upper layer. When a buffer state report event occurs, a buffer state report controller(810) generates a buffer state report message with respect to the data stored in the transmission buffer. A transmission resource allocation requesting unit(815) requests resource allocation from a base station. A transmission/reception unit(830) multiplexes data transferred from the transmission buffer and the buffer state report controller, transmits them to the base station, and transmits the request for resource allocation to the base station according to corresponding request of the transmission resource allocation requesting unit. A transmission controller(820) receives a control channel through the transmission/reception unit to check whether there are resources that have been allocated by the base station, and transmits the check result to the buffer state report controller.

Abstract: An apparatus and a method for transmitting and receiving encoded packets in a mobile communication system are provided to prevent loss of packets by reporting decryption failure of encrypted packets to a transmitting device. A receiving PDCP(Packet Data Convergence Protocol) entity(505) receives packets including encrypted compression headers from a transmitting PDCP entity(520). The receiving PDCP entity senses the failure of the header recovery of the packets and transmits a PDCP initialization message to the transmitting PDCP entity. The receiving PDCP entity receives a response message including a hyper frame number used for decryption of the compression headers from the transmitting PDCP entity, and abolishes the packets stored in a receiving buffer. The packets are decrypted after a PDCP initialization process by using the hyper frame number.

Abstract: A handover method and apparatus in a mobile communication system are provided to allow a terminal to transmit a status report to a source ENB(Evolved Node B) immediately before handover occurs, and not retransmit RLC PDU(Packet Data Unit)s, which have not received a positive acknowledgement signal yet, thereby minimizing a data amount from the source ENB to a target ENB. A measurement controller(1205) controls measurement of the size of a reception signal of neighbor cells. A radio resource controller(1210) generates a measurement result received from the measurement controller(1205) as a message and transmits the same to a base station of a source cell. Before performing handover to a target cell, a radio link controller(1220) receives a status report command from the radio resource controller(1210), generates a status report message, and transmits it to the base station of the source cell. The measurement controller(1205) determines whether the measurement result report satisfies handover conditions previously agreed with the base station of the source cell. The radio resource controller transmits the status report command to the radio link controller(1220) according to determination of the measurement controller(1205).

Abstract: A method and an apparatus for transmitting and receiving packets in a mobile communication system are provided to decrease a transmission resource used for transmitting the packets by reducing a size of a sequence number. A one-bit floating gate is inserted into a head of an RLC(Run Length Coding) PDU(Protocol Data Unit)(705) and it is determined whether a serial number is a partial number of an overall number. The RLC PDU includes a serial number length indicator, a serial number, an additional header, and a payload. The serial number length indicator(710) of the first RLC PDU indicates that a partial serial number is used. The partial serial number is inserted into a serial number field(715). When the serial number length indicator is set to zero, the partial serial number is allocated in the serial number field. A serial number length indicator of a retransmitted RLC PDU declares than an overall serial number is used. The overall serial number is inserted into the serial number field. When the serial number length indicator is set to one, the overall serial number is allocated in the serial number field.
