A method of determining when to apply a changed minimum scheduling offset restriction in a wireless communication system, the method being performed by a user equipment, UE, and comprising: receiving (S 161), in a slot n of a scheduling cell, a first downlink control information, DCI, with a field indicating a change to K 2min, which is a minimum scheduling offset restriction related to a minimum value of an offset between a slot for receiving a second DCI and a slot for transmitting a physical uplink shared channel, PUSCH, scheduled by the second DCI, receiving the second DCI based on a changed K 2min value in slot n+X of the scheduling cell, and transmitting a PUSCH scheduled by the second DCI, wherein the X is determined based on a following equation, X = max Y ⋅ 2 μ PDCCH 2 μ PDSCH Z wherein the Y is a currently applied K 0min value in a scheduled cell, the K 0min is a minimum scheduling offset restriction related to a minimum value of an offset between a slot for receiving the first DCI and a slot for receiving a physical downlink shared channel, PDSCH, scheduled by the first DCI, the μ PDCCH is a subcarrier spacing configuration for a physical downlink control channel, PDCCH, in the scheduling cell, the μ PDSCH is a subcarrier spacing configuration for a PDSCH in the scheduled cell, and the Z is a value determined by the subcarrier spacing configuration for the PDCCH in the scheduling cell, wherein based on the subcarrier spacing configuration for the PDCCH in the scheduling cell being 15kHz, 30kHz, 60kHz, 120kHz, the Z is 1, 1, 2, 2, respectively, and wherein, based on the first DCI being received in symbols after a specific symbol index of the slot n, the X is determined after increasing the Z by 1. receiving (S 161), in a slot n of a scheduling cell, a first downlink control information, DCI, with a field indicating a change to K 2min, which is a minimum scheduling offset restriction related to a minimum value of an offset between a slot for receiving a second DCI and a slot for transmitting a physical uplink shared channel, PUSCH, scheduled by the second DCI, receiving the second DCI based on a changed K 2min value in slot n+X of the scheduling cell, and transmitting a PUSCH scheduled by the second DCI, wherein the X is determined based on a following equation, X = max Y ⋅ 2 μ PDCCH 2 μ PDSCH Z wherein the Y is a currently applied K 0min value in a scheduled cell, the K 0min is a minimum scheduling offset restriction related to a minimum value of an offset between a slot for receiving the first DCI and a slot for receiving a physical downlink shared channel, PDSCH, scheduled by the first DCI, the μ PDCCH is a subcarrier spacing configuration for a physical downlink control channel, PDCCH, in the scheduling cell, the μ PDSCH is a subcarrier spacing configuration for a PDSCH in the scheduled cell, and the Z is a value determined by the subcarrier spacing configuration for the PDCCH in the scheduling cell, wherein based on the subcarrier spacing configuration for the PDCCH in the scheduling cell being 15kHz, 30kHz, 60kHz, 120kHz, the Z is 1, 1, 2, 2, respectively, and wherein, based on the first DCI being received in symbols after a specific symbol index of the slot n, the X is determined after increasing the Z by 1.
