<p>Disclosed is a method for providing a synchronism deviation time, mainly comprising: a rendezvous point device receiving an uplink symbol transmitted by an opposite end device and acquiring an initial position X of the uplink symbol in a time domain; the rendezvous point device computing a deviation time Deltat between x and a preset time domain position z, z being after an end position of the last downlink symbol transmitted in a downlink time period in the time domain and before an end position in an uplink time period; and generating identification information, the identification information being used for identifying whether x is before or after z; and the rendezvous point device transmitting the Deltat and the identification information to the opposite end device. Provided also are a corresponding device and system. The present invention provides a deviation time to an opposite end device for adjusting the transmission time of an uplink symbol. The present invention is advantageous in that after the transmission time of an uplink symbol is adjusted for each opposite end device, the uplink symbol is transmitted to a rendezvous point device, thereby facilitating the cancellation of crosstalk and reducing the influence of the far-end crosstalk.</p> |
