Abstract: In a wireless communication system, a user equipment, already configured with a first medium access control (MAC) entity for a master cell group (MCG) associated with a master base station, capable of configuring a secondary cell group (SCG) associated with a secondary base station based on a radio resource control (RRC) message received from the master base station. The user equipment can configure a second MAC entity for the newly configured SCG. Through a second RRC message from the master base station, the user equipment can then add a new SCG cell to the SCG, where the second MAC entity is commonly configured for one or more secondary SCG cells belonging to the SCG.

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: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for triggering a power headroom reporting in wireless communication system, the method comprising: triggering a Power Headroom Reporting (PHR) when a timer expires or has expired and a status of one of multiple bandwidth parts or multiple beams, which are to be used by the UE, is changed; and transmitting the triggered PHR to a network.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for determining result of transmission for contention-based PUSCH in a wireless communication system, the method comprising: transmitting a MAC PDU using a CB grant to an eNB; starting a timer when the UE transmits the MAC PDU using the CB grant; monitoring an ACK indication transmitted by the eNB while the timer is running; considering that the MAC PDU transmission using the CB grant is failed if the UE doesn't receive the ACK indication from the eNB until the timer expires; and retransmitting the MAC PDU to the eNB.

Abstract: A user equipment (UE) receives a physical downlink control channel (PDCCH) scheduling a data transmission, and starts a hybrid automatic repeat request (HARQ) round trip timer (RTT) timer for the data transmission. The HARQ RTT timer is set to a non-negative value associated with a radio network temporary identifier (RNTI) addressing the PDCCH.

Abstract: A method and apparatus for a user equipment (UE) performing random access to a network is disclosed. For this end, the UE determines a predetermined number of beams, as candidate beams for the random access to the network, among multiple beams, wherein each of the multiple beams is allocated on different time domain units. And, the UE transmits the random access preamble over a transmission beam selected as one from the candidate beams to the network.

Abstract: According to the present invention, a user equipment (UE) receives semi-persistent scheduling (SPS) resource configuration information relating to SPS resources and receives an SPS command indicating activation or deactivation of the SPS resources. The UE flushes, in response to the SPS command, a buffer of an HARQ process associated with an SPS resource to transmit an SPS confirmation medium access control (MAC) control element (CE). The UE transmits a new MAC protocol data unit (PDU) including the SPS confirmation MAC CE on the SPS resource by using the HARQ process.
