Abstract: A method for transmitting data through a logical channel by a user equipment (UE) in a wireless communication system is disclosed. The method comprises determining whether data for the logical channel exists or not; increasing a token value based on a prioritized Bit Rate (PBR) and a time elapsed since the data becomes available for the logical channel, when the data for the logical channel exists; and transmitting the data or a part of the data through the logical channel, when the token value is greater than 0, wherein when there is no data for the logical channel, the token value is not increased.

Abstract: In the performance of a proximity-based services (ProSe) user equipment (UE)-to-network relay operation, when a remote UE needs to transmit control/user plane data to a network, a relay UE may be in a radio resource control (RRC) idle state. At this time, the relay UE receives an RRC connection establishment cause from the remote UE, and performs an RRC connection establishment procedure for the ProSe UE-to-network relay of the remote UE on the basis of the received RRC connection establishment cause.

Abstract: A method and apparatus for master cell group (MCG) radio link failure (RLF) reporting during secondary cell group (SCG) suspension in a wireless communication system is provided. A wireless device detects a failure on a master cell group (MCG) while a secondary cell group (SCG) is suspended, and transmits MCG failure information informing the failure on the MCG by using a physical uplink control channel (PUCCH) format via the SCG, based on unavailability of physical uplink shared channel (PUSCH) transmission via the SCG.
