Abstract:
PROBLEM TO BE SOLVED: To provide a method and apparatus using at least two timers for RLF processing of a wireless communication system. SOLUTION: The method includes a step of determining when to enter an idling mode or when to release a wireless resource by using at least two first timers for a first entity for recover or re-establishment of a radio link or using at least two second timers for a second entity.

Abstract:
PROBLEM TO BE SOLVED: To provide a method for preventing the waste of wireless resources and the overload of a system by setting the service grant (SG) of a user end in a wireless communication system. SOLUTION: The method comprises steps of determining a maximum SG value when a non-service relative grant (NSRG) message is received, and updating the SG value on the basis of the maximum SG value.

Abstract:
PROBLEM TO BE SOLVED: To provide a method and an apparatus for data framing in a wireless communications system. SOLUTION: The disclosed method includes the steps of: when coupling a plurality of higher-layer packets as a lower-layer packet, defining a sequence number of a first higher-layer packet, among the plurality of higher-layer packets, as a sequence number of the lower-layer packet and removing sequence numbers of the plurality of higher-layer packets, other than the first higher-layer packet, from the lower-layer packet.

Abstract:
PROBLEM TO BE SOLVED: To provide method and device for processing packet resending in radio communication system. SOLUTION: The method is constituted of a step, in which an HARQ process is started and when the number of times of transmission of a packet, whose sequence number is the first value, has reached a predetermined maximum number of times of transmission and a confirmation signal corresponding to the packet has not been arrived, the sequence number of the packet is made to be a second value and the packet is sent again while changing the label into a new packet.

Abstract:
PROBLEM TO BE SOLVED: To provide a method for initializing a storage window of a receiving end in a wireless communication system in order to solve various problems caused by the prior art, and an associated apparatus. SOLUTION: The disclosed method includes a step of initializing, after a receiving entity of the receiving end is established/re-established, or after the predetermined period of a timer in the receiving end expires and the receiving end receives a packet, a variable which represents a maximum sequence number among received packets in the receiving end, according to a sequence number of the received packet.

Abstract:
PROBLEM TO BE SOLVED: To provide a method and apparatus for processing a control PDU upon re-establishing a transmitter side in a radio communication system. SOLUTION: The method includes steps of re-establishing only the transmitter side in an RLC entity of a communication apparatus, deleting a first control PDU corresponding to the transmitter side, and retaining a second control PDU without deleting the second control PDU corresponding to a receiver side.

Abstract:
PROBLEM TO BE SOLVED: To provide a method and device for improving a signal transmission rate in a wireless communication system. SOLUTION: In order to improve a signal transmission rate, a data packet is transmitted the predetermined number of times. The predetermined number of times is larger than 1.
