Abstract: A method and apparatus for performing a random access (RA) procedure in a wireless communication system is provided. A user equipment (UE) establishes connection with a first node and a second node, and transmits an RA preamble to the second node. If a number of RA preamble transmissions reaches a maximum number, the UE stops uplink (UL) transmission of all cells in a group to which the second node belongs, and transmits an indication indicating that transmission of the RA preamble has failed to the first node.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for re-ordering a PDCP PDU in a dual connectivity system, the method comprising: configuring a radio bearer having one PDCP (Packet Data Convergence Protocol) entity and two RLC (Radio Link Control) enti-ties, wherein the PDCP entity enables a reordering function for PDCP PDUs (Protocol Data Unit) stored in a PDCP buffer; reconfiguring the radio bearer from having two RLC entities to having one RLC entity so that a first RLC entity is released; keeping the reordering func-tion enabled for the PDCP PDUs stored in the PDCP buffer if there is at least one PDCP PDU in the PDCP buffer after releasing the first RLC entity; and disabling the reordering function when the PDCP buffer becomes empty.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for performing a random access procedure in wireless communication system, the method comprising: transmitting a random access preamble (RAP) on a physical random access channel (PRACH) resource in a radio frame; calculating a random access-radio network temporary identifier (RA-RNTI) by considering time-frequency resource associated with the PRACH resource and an index of a first radio frame of the PRACH resource; and monitoring a physical downlink control channel (PDCCH) identified by the calculated RA-RNTI for RAR reception during a RAR window.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for re-ordering a PDCP PDU in a dual connectivity system, the method comprising: receiving a first PDCP PDU from a first RLC entity of a radio bearer; starting a reordering function if the first PDCP PDU is detected to be out of sequence; storing the first PDCP PDU in the PDCP entity; receiving a second PDCP PDU from a first RLC entity or a second RLC entity while the reordering function is running; and delivering at least one stored PDCP PDU with an associated COUNT value less than x+1 in ascending order of an associated COUNT value to an upper layer, if the second PDCP PDU is received from a second RLC entity.

Abstract: A method for controlling uplink transmissions on discontinuous reception (DRX) operation, by a wireless device, in a wireless communication system, the method comprising: configuring a channel quality indicator (CQI)-masking which indicates that at least one of a CQI, a precoding matrix index (PMI), a rank indicator (RI), or a precoding type indicator (PTI) is not to be reported on a physical uplink control channel (PUCCH) when an onDurationTimer is not running; and determining, at a first subframe prior to a second subframe, whether or not the onDurationTimer is to be running at the second subframe, wherein the at least one of the CQI, the PMI, the RI, or the PTI is not to be reported on the PUCCH at the second subframe, if the onDurationTimer is determined, at the first subframe, to be not running at the second subframe.
