Abstract: The present invention relates to a method of performing a downlink (DL) reception by a user equipment (UE) in a wireless communication system. In particular, the method includes the steps of: configuring not to transmit a Hybrid Automatic Repeat Request (HARQ) feedback for a DL HARQ process; upon a first Physical Downlink Control Channel (PDCCH) for the DL HARQ process is detected, starting a timer for monitoring subsequent PDCCHs related to retransmission of the DL HARQ process, without transmitting the HARQ feedback; and monitoring the sub sequent PDCCHs related to retransmission of the DL HARQ process while the timer is running.

Abstract: The present invention relates to a communication between MAC layer entity and PHY layer entity for parallel random access procedures of dual connectivity. In this scheme, a first PHY entity of a user equipment informs a failure of a random access preamble transmission to a first MAC entity of the UE. Then, the first MAC entity continues or stops a random access procedure without performing procedures for a random access failure.

Abstract: A method for a wireless device operating in a wireless communication system includes receiving configuration information for configuring a non-Physical Uplink Control Channel (PUCCH) cell; and transmitting a Hybrid Automatic Repeat request (HARQ) feedback of the non-PUCCH cell on a special cell (SpCell) or a PUCCH cell other than SpCell, according to indication information. Further, when the indication information is not received with the configuration information, the HARQ feedback is transmitted on the SpCell, and when the indication information is received with the configuration information, the HARQ feedback is transmitted on the PUCCH cell.

Abstract: A method for a user equipment (UE) performing a random access to a network supporting NB-IoT (Narrow Band Internet of Things) is disclosed. The UE, operating on a first carrier, can move to a second carrier from the first carrier, and perform a random access procedure on the second carrier. The UE is configured to return to the first carrier, when the random access procedure on the second carrier is not successful, and when the random access procedure is a contention based random access procedure. Here, the first carrier is an anchor carrier if the UE is in RRC_IDLE state, and the first carrier is a configured carrier if the UE is in RRC_CONNECTED state.

Abstract: The present invention relates to a method for performing retransmissions by a transmission end in a wireless communication system. In particular, the method includes the steps of: re-transmitting a data unit to a reception end; and increasing a retransmission counter associated with the data unit, when the retransmission counter associated with the data unit reaches to a max value, reporting a max retransmission indication to an upper layer and setting the retransmission counter associated with the data unit to zero.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for handling an adaptive retransmission in a wireless communication system, the method comprising: receiving a RRC) signaling configuring that the UE skips an UL transmission if there is no data available for transmission, receiving an UL grant for retransmission for a HARQ process when a HARQ buffer of the HARQ process is empty, and discarding the UL grant for the retransmission even if there is data available for transmission.

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.
