Timing synchronization with neighbor nodes different from parent nodes
Methods, systems, and devices for wireless communications are described. A first node of an integrated access and backhaul (IAB) network may identify a second, neighboring non-parent node of the IAB network. The second node may be associated with a timing source which may provide more accurate timing information than the parent node of the first node. The first node may transmit a first random access message to the second node to initiate a random access procedure. The second node may transmit a second random access message to the first node, the second random access message including timing information based on the timing source. The first and second nodes may terminate the random access procedure based at least in part on receiving the second random access message.
