1. A timing adjustment method, performed by a first relay device and comprising:
adjusting timing of a first link state based on first signaling, wherein
the first link state is a link state of the first relay device or the terminal; and
the first signaling is provided by a parent node of the first relay device, wherein the parent node is a last-hop device of the first relay device;
wherein the first relay device is a first integrated access backhaul IAB node;
wherein the first link state is a link state in a first transmission mode, wherein the first transmission mode is that mobile terminal transmission (MT TX) and distributed unit transmission (DU TX) of the IAB node are aligned on time domain unit or work simultaneously;
wherein in a case that the first signaling is medium access control control element (MAC CE) signaling, the MAC CE signaling is used for indicating that MT TX follows timing of DU TX.
