Radio link establishment method, information transmission method and apparatus, and layer 1 forwarding node

A forwarding configuration method, comprising:

• sending, by a network-side device, first information to a terminal module, the first information comprising at least one of the following:
• first pre-configuration information, the first pre-configuration information being used for pre-configuring initiation of a radio link establishment procedure when the terminal module is in a first state and a forwarding function of a forwarding unit is configured to be completely or partially enabled, wherein the terminal module and the forwarding unit belong to a same layer 1 forwarding node, and the first state comprises a radio resource control (RRC) idle state or an RRC inactive state;
• or
• second configuration information, the second configuration information being configured by the network-side device before the terminal module enters the first state, and the second configuration information being used for configuring wireless channels or resources for receiving side control information when the terminal module is in the first state.

A layer 1 forwarding node, comprising:

• a memory storing a computer program;
• and a processor coupled to the memory and configured to execute the computer program to perform operations comprising:
• when a terminal module is in a first state, in response to a forwarding function of a forwarding unit being configured to be completely or partially enabled, initiating, by the terminal module, radio link establishment when meeting a first condition, wherein the terminal module and the forwarding unit belong to the layer 1 forwarding node, the first state comprises a radio resource control (RRC) idle state or an RRC inactive state, and the meeting a first condition comprises at least one of the following:
• the layer 1 forwarding node being abnormal, or a network-side device configuring or pre-configuring the terminal module to initiate radio link establishment.
