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).

Abstract: A radio link control (RLC) entity of a transmitting device receives a first RLC service data unit (SDU) from an upper layer of the transmitting device. If the RLC entity receives, from the upper layer, a discard indication to discard the first RLC SDU, the RLC entity checks whether the first RLC SDU has been submitted to a lower layer of the transmitting device. The RLC entity discards the first RLC SDU if neither the first RLC SDU nor a segment of the first RLC SDU has been submitted to the lower layer.

Abstract: A method for a User Equipment (UE) operating in a wireless communication system including a Primary Cell (PCell) and a first Secondary Cell (SCell) with a Physical Uplink Control Channel (PUCCH) resource. The method includes receiving a parameter included in information about a second SCell without the PUCCH resource. The parameter indicates that a Hybrid Automatic Repeat Request (HARQ) feedback of the second SCell is to be sent on the first SCell. The method further includes transmitting the HARQ feedback of the second SCell to the first SCell.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for configuring uplink grants over multiple subframes in a wireless communication system, the method comprising: receiving an uplink grant from an eNodeB (eNB), wherein the uplink grant is valid during a specific time duration; transmitting data using the uplink grant when the data is generated during the specific time duration; and discarding the uplink grant when the specific time duration is passed.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for removing a last PUCCH resource of a PUCCH group in a carrier aggregation system, the method comprising: configuring a first Physical Uplink Control Channel (PUCCH) group, wherein the first PUCCH group is composed of one or more first cells with PUCCH resource and zero or more second cells without PUCCH resource; and deactivating all cells belonging to the first PUCCH group, if a last PUCCH resource of the first PUCCH group is released.
