Abstract
Embodiments of the present disclosure disclose a method, an apparatus, and an electronic device for an absolute time synchronization, the method comprising: receiving, from a baseband processing chip, a first timing signaling and a first real system frame information of the received first timing signaling, the first timing signaling comprising a first absolute time corresponding to local time of a base station at time of transmission of the first timing signaling, and a first reference system frame information used by the base station for transmitting the first timing signaling; calculating a first time delay between the base station and the terminal based on at least the first absolute time, if the first real system frame information is consistent with the first reference system frame information; receiving, from the baseband processing chip, subsequent timing signalings and corresponding second real system frame information used by the base station for transmitting the subsequent timing signalings to the terminal, the subsequent timing signalings each comprising a second absolution time corresponding to the local time of the base station at time of transmission of the subsequent timing signaling and a second reference system frame information used by the base station for transmitting the subsequent timing signaling; for each of the subsequent timing signalings, determining a time delay adjustment value between the subsequent timing signaling and the first timing signaling based on at least the first time delay and the second absolute time, if the second real time system frame information is consistent with the second reference system frame information; and after a number of the received subsequent timing signalings reaches a target number, obtaining an absolute time information based on the time delay adjustment values corresponding to the target number of subsequent timing signaling; wherein the absolute time information is used to synchronize time of the terminal to time of the base station.
