Abstract: The present invention relates to a method for transmitting signals by a user equipment (UE) in a radio resource control (RRC) inactive state or a RRC idle state at a wireless communication system. In particular, the method includes the steps of: measuring neighboring cells; identifying one of the neighboring cells fulfilled with conditions for a cell reselection procedure based on a result of measuring; determining whether to perform the cell reselection procedure with the one of the neighboring cells by considering a timer; and transmitting an uplink data or receiving a downlink data, without performing the cell reselection procedure during the timer is running, when it is determined not to perform the cell reselection procedure.

Abstract: A method for monitoring a physical downlink control channel (PDCCH) with a discontinuous reception (DRX) related timer by a user equipment (UE) configured not to transmit a Hybrid Automatic Repeat and request (HARQ) feedback for the DL HARQ process in a wireless communication system is disclosed. Especially, when the UE processes the data block, a timer for monitoring subsequent PDCCHs related to retransmission of the DL HARQ process is started without transmitting the HARQ feedback upon a first Physical downlink Control Channel (PDCCH) for the DL HARQ process is detected. Then, while the timer is running, the UE monitors subsequent PDCCHs related to retransmission of the DL HARQ process. Further, when decoding of DL data related to the second PDCCH successes, the timer is stopped and monitoring subsequent PDCCHs for the DL HARQ process is skipped.

Abstract: In the present invention, the transmitting device attaches a sequence number (SN) for each of service data unit (SDU) elements to generate a protocol data unit (PDU) containing the SDU elements. Each of the SDU elements is a SDU or SDU segment. The PDU includes the SDU elements and respective SNs for the SDU elements. The PDU includes an indicator for each of the SDU elements, and the indicator indicating whether a corresponding SDU element is a SDU or SDU segment.

Abstract: A user equipment (UE) determines whether a size of data available for transmission in a PDCP (Packet Data Convergence Protocol) entity of the UE, excluding a size of a PDCP Control PDU (Protocol Data Unit), exceeds a threshold value. Here, the PDCP Control PDU is predetermined to be transmitted through the first link of the bearer. The PDCP entity of the UE informs an indication on (a) the size of the data available for transmission, or (b) the size of the PDCP Control PDU, to a first entity of the UE for the first link based on the determination, and the first entity can transmit a buffer status report to the network based on the indication. Here, the size of the data available for transmission in the PDCP includes the size of the PDCP Data PDU and the size of the PDCP Control PDU.

Abstract: Provided are a method in which a source base station (BS) transmits a Quality of Service (QoS) flow-to-data radio bearer (DRB) mapping rule to a target BS in a wireless communication system, and a device supporting the same. The method may include: receiving, from a user equipment (UE), a measurement result of a target cell; determining the handover of the UE to the target BS on the basis of the measurement result; and transmitting, to the target BS, a handover request message including a QoS flow-to-DRB mapping rule of the source BS.

Abstract: A method for performing a random access (RA) procedure by a user equipment (UE) in a wireless communication system is provided. The method comprises: selecting a uplink carrier for the RA procedure between a first uplink carrier for a serving cell and a second uplink carrier for the serving cell; and performing a first random access preamble (RAP) transmission for the RA procedure through the selected uplink carrier. Selecting the uplink carrier comprises: selecting the first uplink carrier when a downlink signal quality of the serving cell is less than a first threshold, and selecting one of the first and second uplink carriers randomly when the downlink signal quality of the serving cell is equal to or above the first threshold.

Abstract: A user equipment (UE) receives first configuration information for one or more numerology sets, each numerology set including one or more numerologies. The UE receives second configuration information for one or more logical channels, each logical channel mapped to one or more numerologies. The UE receives a first uplink (UL) grant for new transmission, the first UL grant including information indicating a numerology set associated with the first UL grant. The UE generates a MAC PDU. The UE performs a new transmission of the MAC PDU using the first UL grant. The MAC PDU contains data from a logical channel of which every numerology belongs to the numerology set.

Abstract: A transmitting device of the present invention submits, from a packet data convergence protocol (PDCP) entity configured with a PDCP duplication function, a PDCP protocol data unit (PDU) (duplicated PDCP PDU 1) to a lower layer and starts a prohibit timer for the duplicated PDCP PDU 1. The transmitting device submits, from the PDCP entity, the same PDCP PDU (duplicated PDCP PDU 2) to the lower layer if the prohibit timer expires. The transmitting device transmit the duplicated PDCP PDU 1 and the duplicated PDCP PDU 2.
