Abstract: A first relay node receives a first timeslot assignment message sent by an upper-level node, where the first timeslot assignment message includes forwarding information and first timeslot information, and the forwarding information includes a forwarding indication indicating that at least one relay node needs to forward the first timeslot assignment message. The first relay node updates the first timeslot information to obtain second timeslot information, where the updating includes deleting an expired timeslot indication from the first timeslot information. The first relay node sends a second timeslot assignment message including the forwarding information and the second timeslot information.
