1. A method, comprising:
receiving, by an integrated access and backhaul (IAB) node, a medium access control control element (MAC CE) including a Tdelta field for a value used to control an amount of timing adjustment from a parent node, wherein a length of the Tdelta field is 11 bits, and
determining a time difference between a distribution unit (DU) transmission of a signal from the parent node and reception of the signal by a mobile terminal (MT) of the IAB node, based on a predetermined parameter and the value provided by the Tdelta field,
wherein the predetermined parameter is different according to a frequency range (FR) of the IAB node.
