Time synchronization method, ue, base station, device and computer readable storage medium

A time synchronization method in a wireless communication system, performed by a base station, the method comprising:

• receiving an uplink transmission signal from at least one UE;
• estimating a propagation delay of each UE according to the uplink transmission signal;
• and
• transmitting corresponding indication information to each UE according to the propagation delay of each UE, wherein the indication information is used to indicate a propagation delay between each UE and the base station and/or the time information of the TSN.

A User Equipment(UE) in a wireless communication system, the UE comprising:

• a transceiver;
• a memory configured to store at least one instruction;
• a processor configured to:
• receive indication information, wherein the indication information being used to indicate at least of a propagation delay between the UE and a base station or time information of a time sensitive network (TSN),
• determine a time granularity of one bit of the indication information and
• perform TSN time synchronization according to the indication information and the time granularity of one bit of the indication information.
