Abstract: The present invention relates to a method of receiving data units by a user equipment (UE) in a wireless communication system. In particular, the method includes the steps of: receiving the data unit during an active time of a first discontinuous reception (DRX) configuration related to a multicast transmission for a Hybrid Automatic Repeat and request (HARQ) process; transmitting a negative response to the network based on the data unit being not successfully decoded; starting a HARQ Round-trip Time (RTT) timer of a second DRX configuration related to a unicast transmission for the HARQ process; and monitoring a physical downlink control channel (PDCCH) related to a retransmitted data unit during an active time of the second DRX configuration, based on the HARQ RTT timer expiring.

Abstract: A method and apparatus for determination of a maximum number of uplink retransmissions in a wireless communication system is provided. A wireless device receives, from a network, information related to a first retransmission number for a first logical channel and second retransmission number for a second logical channel, determines a retransmission number of a data unit among the first retransmission number and the second retransmission number, and transmits, to the network, information for the retransmission number of the data unit.

Abstract: A method and apparatus for reconstruction of a protocol data unit (PDU) for fast and reliable retransmission of a service data unit (SDU) after maximum retransmission is provided. Upon determining that a hybrid automatic repeat request (HARQ) retransmission of a first PDU including a specific SDUis unsuccessful, a wireless device constructs a second PDU including the first SDU which is prioritized to be included in the second PDU.

Abstract: In the present disclosure, a transmitting device generates a medium access control (MAC) protocol data unit (PDU) including a MAC subPDU, and transmits the MAC PDU. The MAC subPDU includes a MAC subheader for a MAC service data unit (SDU) of a logical channel. The MAC subheader includes a length field regarding a length of the MAC SDU of the logical channel, and no logical channel identifier (LCID) field for identifying the logical channel.

Abstract: A method and apparatus for discarding data among associated transmission buffers in a wireless communication system is provided. A wireless device generates a first data packet and a second data packet, and performs a random access (RA) procedure based on the first data packet. When the RA procedure based on the first data packet fails, the wireless device discards the first data packet, and continues the RA procedure based on the second data packet. A media access control (MAC) layer indicates a radio resource control (RRC) layer that the RA procedure based on the second data packet is performed.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for handling pre-configured UL resources based on LBT procedure in wireless communication system, the method comprising: receiving information for UL resource configuration from a network, in a state that the UE is configured with at least one serving cell operating in an unlicensed spectrum; performing LBT operation for transmission of uplink data by using the UL resource, wherein the UE starts counting a number of failures of the LBT operation once the UE is not allowed to use the UL resource for transmission of uplink data during the LBT operation, and when the number of failures of the LBT operation reaches to the maximum number of LBT failure, stopping using the UL resource.
