Coordination signaling for synchronization signal block (ssb) transmission configurations

An apparatus of an integrated access and backhaul (IAB) donor operable to communicate synchronization signal block (SSB) transmission coordination information, the apparatus comprising:

• one or more processors configured to:
• determine, at the IAB donor in a Fifth Generation New Radio (5G-NR) IAB network, SSB transmission coordination information for the IAB donor and a plurality of IAB nodes;
• and
• encode, at the IAB donor, the SSB transmission coordination information for transmission from a central unit (CU) of the IAB donor to a distributed unit (DU) of an IAB node in the plurality of IAB nodes, wherein the SSB transmission coordination information enables the plurality of IAB nodes to send and receive SSBs to one or more of the IAB donor or other IAB nodes of the plurality of IAB nodes in the 5G-NR IAB network in accordance with a half-duplex constraint;
• and
• a memory interface configured to retrieve from a memory the SSB transmission coordination information.
