1. A method, comprising:
receiving, by an integrated access and backhaul (IAB) node including a mobile termination (MT) and a distributed unit (DU), timing information related to slots; and
applying, by the IAB node, the timing information in the slots,
wherein the timing information is received through a medium access control-control element (MAC-CE), and
wherein the timing information informs each timing alignment case applied to a MT transmission of the IAB node in each slot of the slots, and
wherein the each timing alignment case is related to at least one of MT transmission time of the IAB node or DU transmission time of the IAB node, and
wherein a first timing alignment case is applied to a first slot among the slots and a second timing alignment case is applied to a second slot among the slots based on the timing information, and
wherein the each timing alignment case is one of a timing alignment case 1, a timing alignment case 6, and a timing alignment case 7, and
wherein, in the timing alignment case 1, the MT transmission time of the IAB node is determined based on timing advance (TA) configuration information which is provided, and
wherein, in the timing alignment case 6, the MT transmission time of the IAB node is determined based on the DU transmission time of the IAB node, and
wherein, in the timing alignment case 7, the MT transmission time of the IAB node is determined based on additional TA configuration information which is provided.
