Abstract: The present invention relates to a method of transmitting a signal by a user equipment (UE) in a wireless communication system. Especially, the method includes the steps of receiving a handover command containing configurations for a second network, from a first network; performing a random access procedure to the second network; re-establishing a packet data convergence protocol (PDCP) entity associated with a signaling radio bearer (SRB) based on the configurations for the second network, after a random access procedure to the second network successes; transmitting a radio resource control (RRC) message to the second network using the re-established PDCP entity.

Abstract: A method and apparatus for paging procedure considering network slicing in a wireless communication system is provided. A wireless device receives, from a network, a paging message including information related to a mobile terminated (MT) service. A wireless device transmits, to the network, a paging response message including information on Single-Network Slice Selection Assistance Information (S-NSSAI) for the MT service. A wireless device receives, from the network, the MT service from a cell related to the S-NSSAI. The cell is determined based on the paging response message.

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: A method and apparatus for completion mechanism for transmission using preconfigured uplink resource (PUR) in a wireless communication system is provided. While in a radio resource control (RRC) idle state and/or an RRC inactive state, a wireless device configured to operate in a wireless communication system i) performs uplink (UL) data transmission using a preconfigured uplink resource (PUR) to a network, ii) attempts to acquire downlink (DL) information on a physical downlink shared channel (PDSCH) from the network, and iii) based on the DL information including only timing advance command (TAC) media access control (MAC) control element (CE), considers that the UL data transmission using the PUR is successful.

Abstract: The present disclosure relates to a method of processing signals by a user equipment (UE) in a wireless communication system. Especially, the method includes the steps of receiving a data signal including a data unit for a multicast/broadcast service (MBS) based on a control signal addressed with a Group-Radio Network Temporary Identifier (G-RNTI) from a network; identifying a logical channel for the MBS among two or more logical channels, based on the G-RNTI and a logical channel identifier; and transferring the data unit for the MBS to the identified logical channel.

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: A method and apparatus for flushing a hybrid automatic repeat request (HARQ) buffer in a wireless communication system is provided. A user equipment (UE) receives information on multiple resource pools from a network, selects a first resource pool among the multiple resource pools, and stores a media access control (MAC) protocol data unit (PDU) in the HARQ buffer for transmission via the first resource pool. When the UE reselects a second resource pool among the multiple resource pools, the UE flushes the HARQ buffer.
