Abstract: In the present disclosure, a UE generates a power headroom report, and transmits the power headroom report to a network. The power headroom report includes a configured transmit power (CTP) field for a serving cell based on a CTP value for the serving cell being not equal to a last reported CTP value for the serving cell. The power headroom report includes no CTP field for the serving cell based on the CTP value for the serving cell being equal to the last reported CTP value for the serving cell. The power headroom report may include first information on whether the CTP field for the serving cell exists after a power headroom filed for the serving cell.

Abstract: The present disclosure relates to a method for transmitting a protocol data unit (PDU) by a transmission end in a wireless communication system. In particular, the method includes receiving an uplink (UL) grant from a network; when the UL grant can accommodate all of pending data for a first logical channel but is not sufficient to additionally accommodate a buffer status report (BSR), including the pending data for the first logical channel to the PDU with canceling the BSR; and transmitting the PDU to the network, wherein the UL grant cannot additionally accommodate all of pending data for a second logical channel.

Abstract: The present invention relates to a method for transmitting signals by a transmission end in a wireless communication system. In particular, the method includes the steps of: configuring one Packet Data Convergence Protocol (PDCP) entity, at least one first RLC entity related to the one PDCP entity and at least one second RLC entity related to the one PDCP entity; determining whether a service data unit (SDU) to be transmitted is a special SDU or not; if the SDU is the special SDU, transmitting the SDU to the at least one first RLC entity; and if the SDU is not the special SDU, transmitting the SDU to the at least one second RLC entity.

Abstract: The present invention constructs L RLC PDUs, where L is larger than 1; and submit the L RLC PDUs to a medium access control (MAC) layer for a transmission opportunity. The L RLC PDUs include a first RLC PDU having a poll to trigger status reporting at a receiving device and a second RLC PDU not having the poll and having a highest sequence number (SN) among SNs of the L RLC PDUs. The present invention sets a state variable to a highest SN among SNs of RLC PDUs having the poll submitted to the MAC layer, upon submitting the first RLC PDU to the MAC layer.

Abstract: A method for performing a configured grant based small data transmission (CG-SDT) in a Radio Resource Control (RRC) INACTIVE state by a user equipment (UE) in a wireless communication system is disclosed. The method comprises steps of performing an initial transmission for the CG-SDT on a configured grant (CG), wherein a configured grant timer (CGT) and a CG-SDT-retransmission timer (CG-SDT-RT) are started by performing the initial transmission; and based on a physical downlink control channel (PDCCH) related to the initial transmission not being received until the CG-SDT-RT expiring during the CGT is running, performing a retransmission of the initial transmission, wherein the CG-SDT-RT is re-started upon performing the retransmission of the initial transmission, wherein, based on the PDCCH related to the initial transmission not being received until the CGT expiring, a SDT failure handling procedure is triggered.
