Provided are a timing information configuration method, apparatus and system and a storage medium. The timing information configuration method includes that a first node predefines or configures timing information of a second node. The timing information includes 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 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. The timing information configuration method includes that a second node determines timing information of the second node in a manner of predefinition or in a manner of being configured.
