摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： Method and apparatus for a user equipment (UE) transmitting uplink signals in a wireless communication system are disclosed. For this end, the UE, receiving first uplink grant information and logical channel priority information associated with the first uplink grant, constructs a first data unit including data from one or more radio bearers with first logical channel priority corresponding to the logical channel priority information. And, the UE transmits the first data unit to a network.

摘要： The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for performing a LCP procedure in a carrier aggregation, the method comprising: configuring with a first cell group including at least one first cell and a second cell group including at least one second cell served by an eNB; configuring a plurality of logical channels, wherein each logical channel of the plurality of logical channels respectively corresponds to one of a first type logical channel that cannot be transmitted to the second cell and a second type logical channel that can be transmitted to the second cell; receiving a uplink grant for the first cell or the second cell performing a Logical Channel Prioritization (LCP) procedure.
