Timing synchronization method, device, equipment and medium

Abstract

The invention discloses a timing synchronization method. The method comprises the steps of obtaining the beam number of a target switching beam, and searching a time offset value corresponding to thenumber from a time offset value maintenance file, wherein the time offset value maintenance file stores the number of each wave beam and a historical time offset value, the historical time offset value is the time offset value of the beam in the Nth scanning period before the current scanning period, and N is a positive integer; and generating an adjustment instruction according to the time offsetvalue, wherein the adjustment instruction is used for indicating the sending end to adjust the signal sending time or the receiving end to adjust the signal receiving time. Therefore, the problem oftiming synchronization of switching of different beams in the same cell is solved, the historical values are adopted for timing synchronization, the response speed is increased, adjustment can be conducted in time, system performance reduction or communication interruption is avoided, extra sending of sounding reference signals is not needed, and system expenditure is reduced. The invention further discloses a corresponding device, equipment and a medium.

Description

technical field [0001] The present application relates to the communication field, and in particular to a timing synchronization method, device, equipment and computer-readable storage medium. Background technique [0002] In the field of mobile communication, whether it is the uplink transmission from the mobile user terminal (User Equipment, UE) to the base station (BaseStation, BS), or the downlink transmission from the BS to the UE, it may be affected by the propagation process, resulting in the transmission of the signal to the receiver. The end time is earlier or later than expected. In order to ensure that the signal is received at the expected time, it is usually required for the sending end to send the signal according to a certain timing advance (TA). [0003] When the UE is blocked while moving, the transmission signal energy of the direct path is greatly weakened, and if the signal energy of the reflection path can meet the normal communication, the transmitter ...
