Abstract: The present invention relates to a method for transmitting a packet by a Packet Data Convergence Protocol (PDCP) layer entity of a UE in a wireless communication system. In particular, the method includes submitting a packet periodically to a lower layer if a type of the packet is one of specific types, wherein, when a number of submitting the packet becomes a predetermined value, submitting the packet is stopped.

Abstract: The present invention relates to a method for transmitting signals by a transmission end in a wireless communication system. In particular, the method includes the steps of: configuring one Packet Data Convergence Protocol (PDCP) entity, at least one first RLC entity related to the one PDCP entity and at least one second RLC entity related to the one PDCP entity; determining whether a service data unit (SDU) to be transmitted is a special SDU or not; if the SDU is the special SDU, transmitting the SDU to the at least one first RLC entity; and if the SDU is not the special SDU, transmitting the SDU to the at least one second RLC entity.

Abstract: The present invention relates to a method of transmitting packets by a user equipment (UE) in a wireless communication system, wherein the UE is related to a first network and a second network. In particular, the method includes the steps of: transmitting packets containing compressed header information to the first network; receiving, from the first network, a handover command to connect with the second network; and transmitting packets containing a full header information to at least one of the first network or the second network.

Abstract: The present invention relates to a method for processing data units by a Packet Data Convergence Protocol (PDCP) entity of a user equipment (UE) in a wireless communication system. In particular, the method includes the steps of: receiving a first data unit having a specific count value from a lower layer; and discarding the first data unit, when there is a second data unit having the specific count value which was received before the first data unit and for which an integrity verification was successful.

Abstract: The present invention relates to a method of transmitting a Packet Data Convergence Protocol (PDCP) Protocol Data Unit (PDU) by a transmitter in a wireless communication system. Especially, the method includes the steps of configuring an offset and a specific value for integrity protection; receiving a PDCP Service Data Unit (SDU) including a plurality of octets from an upper layer; generating a Message Authentication Code - Integrity (MAC-I) by performing the integrity protection from a first octet corresponding to the offset among the plurality of octets to a second octet corresponding to the offset plus the specific value among the plurality of octets; and transmitting the PDCP PDU including the PDCP SDU and the MAC-I to the receiver.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for handling state variables of a PDCP entity in wireless communication system, the method comprising: delivering an PDCP SDU associated with a first COUNT to upper layer and starting, by the PDCP entity, a reordering timer, when an out-of-order PDCP PDU with the first COUNT value is received from lower layer; updating a value of a first state variable to the first COUNT value+1, when the reordering timer starts; and when the reordering timer expires, updating, by the PDCP entity, a value of a second state variable based on a second COUNT value of a first PDCP SDU which has not been delivered to upper layers, among PDCP SDUs with COUNT values which are equal to or larger than the first state variable.

Abstract: A method for processing signals by a relay node in a wireless communication system is disclosed. The method comprises detecting a radio link failure (RLF) of a connection with a child node of the relay node; transmitting a message informing an occurrence of the RLF to a parent node of the relay node, wherein the message includes an identifier of the child node.
