Abstract: A method performed by a user equipment (UE) supporting extended reality (XR) in a wireless communication system is provided. The method comprises receiving, from a base station (BS), control information related to a power saving operation, and performing the power saving operation configured based on the control information. The power saving operation may comprise determining a size of a XR-retransmission (reTx) timer based on the control information, starting the XR-reTx timer based on a configured condition, and based on the XR-reTx timer expiring, stopping a monitoring of a physical downlink control channel (PDCCH) including scheduling information for a retransmission of a physical downlink shared channel (PDSCH) from the BS.

Abstract: Provided are a method and a device for determining the application delay value of a minimum scheduling offset restriction in a wireless communication system. The method accesses a specific base station through a random access step, and then, if DCI which includes information for notifying of a change in the minimum scheduling offset restriction value in slot n of the scheduling cell is to be received from the base station, applies the changed minimum scheduling offset restriction value in slot n+X of the scheduling cell. Herein, the X value can be determined on the basis of two parameters such as Y and Z, the Y value is the minimum scheduling offset restriction value to be applied to a scheduled cell scheduled by the DCI, and the Z value is a value predetermined according to the subcarrier spacing of the scheduling cell. In addition, the DCI can increase, by 1, the Z value according to the temporal position at which the DCI is received within slot n.
