A timing information configuration method, comprising:

• determining, by a second node, timing information of the second node in a manner of predefinition or in a manner of being configured;
• wherein the timing information comprises at least one of:
• a timing mode, a downlink transmission timing alignment mode, a timing advance (TA) configuration mode, a TA value, an offset of a TA value, a number of orthogonal frequency division multiplexing (OFDM) symbols that an uplink transmission link timing is advanced or delayed relative to a downlink transmission timing for alignment, or a number of OFDM symbols that an uplink reception timing is advanced or delayed relative to a downlink reception timing for alignment.
