摘要:
A method and apparatus for processing control information included in a data unit in a mobile communication system are provided. A receiver processes control information of a first type immediately irrespective of reordering of a received data unit, when the received data unit comprises the control information of the first type. The receiver processes control information of a second type after reordering of the received data unit, when the received data unit comprises the control information of the second type.

A method and apparatus for increasing the success rate of a handover of a connected mode UE while minimizing the power consumption of the UE during DRX operation in a mobile communication system is provided. The method includes the steps of transmitting a cell change report to the serving base station, and then suspending the DRX operation to transition to an active mode; receiving a handover command message, and completing the handover to a target cell; checking if the handover command message includes a DRX resume command; waiting until a control message including the DRX resume command is received from the target base station; and after the control message including the DRX resume command is received, transitioning from the active mode to a sleep mode, and resuming the DRX operation.

Disclosed is a method and apparatus for transmitting/receiving a packet in a mobile communication system. When upper layer packets are multiplexed into a packet whose overall size is informed via a separate path, the size of the upper layer packet is not signaled if it can be calculated from the overall size of the packet, so that the size a packet transmitted/received over a radio channel can be reduced.
摘要:
A method for receiving a packet by a terminal in a mobile communication system including a base station providing a packet, and a terminal that discontinuously receives a packet from the base station in Discontinuous Reception (DRX) cycles each having an active period and a sleep period. The packet reception method includes receiving, from the base station, configuration information for a DRX service, comprising a DRX cycle length; setting, as a starting point of the DRX cycle, a point at which a first packet is received from the base station; receiving a packet from the base station for an active period at the beginning of the starting point; and transitioning to a sleep period and waiting for a next active period.
摘要:
A method and an apparatus for performing Automatic Retransmission reQuest (ARQ) on packet data in a mobile communication system. The method includes receiving from a transmission entity performing ARQ, by a reception entity , a status report message including a Non-Acknowledged (NACK) signal for the packet data transmitted to the reception entity, and generating time information of the NACK signal; comparing, by the transmission entity, the generation time information with transmission complete time information for the packet data; and determining whether to retransmit the packet data depending on the comparison result, and performing retransmission of the packet data according to the determination step.
摘要:
A retransmission method and apparatus performed in a transmitter of a mobile communication system supporting a Hybrid Automatic Retransmission reQuest (HARQ) operation and an Automatic Retransmission request (ARQ) operation for retransmission of a packet are provided. At least one ARQ entity (505,510,515) generates at least one ARQ packet, and an HARQ entity (525) transmits an HARQ packet (535) including the at least one ARQ packet to a receiver (Rx), and transmits a local NACK signal (517) indicating transmission fail of the ARQ packet to a corresponding ARQ entity (505,510,515), if the HARQ packet fails in transmission (540).
摘要:
Provided is a communication system in which a wireless access network communicates with a mobile station via a wireless link. One of the mobile station and the wireless access network proposes a plurality of candidate transmission gap configurations to the other of the mobile station and the wireless access network, and the other selects one of the candidate transmission gap configurations.
