Timing and frame structure in an integrated access backhaul (IAB) network

A method of wireless communication, comprising:

• receiving, by a first wireless communication device of a multi-hop wireless network, an uplink transmission timing adjustment command indicating a timing advance between an uplink of the first wireless communication device and a downlink of a second wireless communication device, the second wireless communication device at a next uplink hop from the first wireless communication device in the multi-hop wireless network;
• transmitting, by the first wireless communication device to the second wireless communication device at a transmission time, a first communication signal including backhaul data in an uplink direction, the transmission time being based on at least the uplink transmission timing adjustment command;
• and
• transmitting, by the first wireless communication device to a third wireless communication device of the multi-hop wireless network at a next downlink hop from the first wireless communication device based on at least the uplink transmission timing adjustment command, a second communication signal in a downlink direction.
