Abstract: A method for transmitting signals by a medium access control (MAC) entity of a transmission end in a wireless communication system is disclosed. The method includes steps of receiving a protocol data unit (PDU) from a Radio Link Control (RLC) layer; transmitting a signal including the PDU based on a specific coverage enhanced (CE) level to a network; when a transmission of the signal to a network is failed, determining whether a current CE level is changed or not from the specific CE level; if the current CE level is changed from the specific CE level, transmitting an indication requesting a retransmission of the PDU, to the RLC layer; receiving the PDU from the RLC layer; and transmitting a signal including the PDU based on the current CE level to the network.

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 SDU is unsuccessful, a wireless device constructs a second PDU including the first SDU which is prioritized to be included in the second PDU.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for transmitting uplink data which is robust to collision on shared uplink resource in wireless communication system, the method comprising: checking whether uplink data is allowed to transmit on contention based resource or not, when the uplink data becomes available for transmission; and transmitting a buffer status reporting (BSR) on the contention based resource without any uplink data, if the uplink data is not allowed to transmit on the contention based resource.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for transmitting or receiving a MAC PDU in a wireless communication system, the method comprising: setting a LCID field in a MAC subheader to a first value indicating that an eLCID field is included in the MAC subheader when a MAC PDU including the LCID field and the eLCID field is to be generated, setting the eLCID field to a second value identifying a logical channel of a MAC SDU or a type of a MAC CE, and generating and transmitting the MAC PDU including the LCID field and the eLCID field, and the MAC SDU or the MAC CE.

Abstract: In a wireless communication system, user equipment (UE) can reselect a sidelink resource used for vehicle-to-everything (V2X) communication. Reselection of a sidelink resource may be triggered by various conditions, and especially can be triggered when one or more resource pools are configured by an upper layer. In particular, the user equipment determines that data for V2X is present in a sidelink traffic channel (STCH), determines that the one or more resource pools are configured by the upper layer, and reselects the sidelink resource.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for transmitting a MAC CE in different TTI durations in wireless communication system, the method comprising: receiving an indication indicating a TTI duration in which a MAC CE is allowed to be included in a MAC PDU, when one or more different TTI durations are configured to the UE; receiving UL grant with a first TTI duration, when a MAC CE is generated; generating a MAC PDU by performing a LCP procedure for the UL grant based on the indicator; and transmitting the generated MAC PDU in the first TTI duration.
