Abstract: The method for a user equipment (UE) generating a buffer status report (BSR) comprises receiving logical channel configuration information from a network, the logical channel configuration information including information related to a plurality of numerologies mapped to each logical channel; when the BSR is triggered, calculating a buffer size of each numerology based on the logical channel configuration information; and generating a BSR including buffer size information of at least one numerology in decreasing order of numerology priority.

Abstract: A method for a User Equipment, UE, operating in a wireless communication system, includes triggering power headroom reports (PHRs), in a first Medium Access Control (MAC), entity and a second MAC entity when a first type event occurs in the second MAC entity, wherein the UE is configured with the first MAC entity corresponding to a first base station and the second MAC entity corresponding to a second base station for a radio bearer; triggering a PHR in the second MAC entity only, when a second type event occurs in the second MAC entity, wherein the first type event includes: there are uplink resources allocated for transmission on any cell of the second MAC entity and a required power backoff for the any cell of the second MAC entity has changed more than a threshold, or wherein the first type event includes: there is uplink transmission on any cell of the second MAC entity and a required power backoff for the any cell of the second MAC entity has changed more than a threshold.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for triggering a sidelink buffer status reporting in a D2D communication system, the method comprising: configuring a first ProSe destination including at least one first UE and a second ProSe destination including at least one second UE; receiving a first sidelink data for a first sidelink logical channel from an upper layer; receiving a second sidelink data for a second sidelink logical channel from the upper layer while the UE has the first sidelink data for the first logical channel, wherein the second logical channel has a higher priority than a priority of the first sidelink logical channel; and triggering a buffer status reporting the if the first sidelink logical channel and the second sidelink logical channel belong to a same ProSe destination.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for reporting an RLC (Radio Link Control) re-transmission failure in the wireless communication system, the method comprising: communicating with both the first BS and the second BS, wherein the first BS has a Radio Resource Control (RRC) connection with the UE; and reporting to the first BS, a Radio Link Control (RLC) retransmission error without RRC connection re-establishment for the first BS if the RLC retransmission error occurs in an RLC entity transmitting RLC PDU (Protocol Data Unit) to the second BS.

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: In the present invention, a user equipment (UE) transmits a SI request (SIR) medium access control (MAC) control element (CE) for requesting one or more SIs. The UE receives the requested one or more SIs on a cell. The SIR MAC CE includes information indicating which SI among a plurality SIs used in the RAT system the UE requests.

Abstract: In the present invention, a transmitting device receives, at a packet data convergence protocol (PDCP) layer, a PDCP service data unit (SDU) from an upper layer. The transmitting device generates, at the PDCP layer, a PDCP protocol data unit (PDU) containing the PDCP SDU. The transmitting device submits, at the PDCP layer, the PDCP PDU to a lower layer. If the PDCP SDU includes a transmission control protocol (TCP) ACK packet, the PDCP layer generates a PDCP control PDU as the PDCP PDU.

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 UE can support a LWA operation for uplink data transmission. The UE can inform a base station of the amount of uplink data available transmission by a buffer status report. For the purpose of the buffer status report, the UE considers PDCP SDUs sent over LTE and no PDCP SDU sent over WLAN as uplink data available transmission.

Abstract: A radio link control (RLC) entity can be used for multiple radio bearers (RBs). In other words, one RLC entity can be associated with multiple packet data convergence protocol (PDCP) entities, where the multiple PDCP entities are associated with the multiple RBs, respectively. An identifier of a PDCP or RB can be provided with a PDCP PDU in order to inform the RLC entity or a receiving device which RB or which PDCP entity the PDCP PDU is associated with. The RLC entity shared by more than one RB can be configured according to configuration information for RB(s).
