Provided are an operation method performed by a first distributed unit (DU) of a first parent node communicating with a mobile terminal (MT) of an IAB node in a wireless communication system, and a device using the method. The first parent node acquires first configuration information about the first DU, acquires second configuration information about a second DU of a second parent node communicating with the MT, and restricts, on the basis of the first configuration information and the second configuration information, downlink transmission or uplink reception operations of the first DU if predetermined conditions are satisfied.

Operation method of DU of parent node communicating with MT of IAB node in wireless communication system, and device using method

The present invention relates to a method for performing a random access procedure in a wireless communication system and an apparatus therefor, the method comprising the steps of: receiving a physical downlink control channel (PDCCH) order, which indicates initiation of a random access procedure, from a base station; transmitting a random access preamble to the base station; and receiving a random access response message from the base station, wherein the step of receiving the random access response message comprises receiving downlink data together with the random access response message when the PDCCH order indicates downlink data transmission in Msg2.

Method for performing random access procedure and apparatus therefor

According to at least one of the embodiments disclosed herein, a user equipment (UE) may transmit a configured grant (CG) based physical uplink shared channel (PUSCH). However, based on that the CG-based PUSCH is transmitted in a radio resource control (RRC) Inactive state and that the CG-based PUSCH is associated with a specific synchronization signal block (SSB) among broadcast SSBs, the UE may monitor a physical downlink control channel (PDCCH) based on the specific SSB while maintaining the RRC Inactive state.
