Disclosed are a time synchronization method, device and communication system, the method comprising: a second wireless communication device acquires a first frame number of a first-second signal transmitted by a first wireless communication device via a transmission path; acquiring a reference reception time of the debugging signal group to which the first-second signal belongs; a second wireless communication device determines a target reference frame number according to the reference frame number of the first-second signal; recording a reference reception time of a second-second signal corresponding to the target reference frame number, and according to a receiving interval in receiving the debugging signal group, the reference reception time of the first second signal and the reference reception time of the second-second signal, determining the delay of the reference reception time of the second-second signal with respect to the transmission time of the second-second signal; the second wireless communication device compensates for the reference reception time of the second-second signal according to the delay, so as to obtain a reception time in sync with the transmission time of the second-second signal, thus enabling the synchronization time to be more accurate. |
