Abstract
Embodiments include methods performed by an integrated access backhaul (JAB) node configured for operation in an IAB network. Such methods include receiving, from an upstream node in the IAB network, first timing offset information related to communications between the IAB node and the upstream node. Such methods include transmitting a downlink (DL) signal to one or more downstream nodes in the IAB network. The DL signal is transmitted according to a DL transmission timing determined from the following: the IAB node's DL reception timing of a DL signal received from the upstream node; and a second timing value determined based on a first function of the first timing offset information, when the first function of the first timing offset information is greater than a threshold. Other embodiments also include IAB nodes configured to perform such methods.
