1. A method for uplink (UL) synchronization, performed by a terminal device, the method comprising:
determining one or more transmission gaps in a UL shared channel resource, wherein the UL shared channel resource is a resource occupied by a scheduled UL shared channel, and the one or more transmission gaps are each M continuous time units subsequent to every N time units in the UL shared channel resource;
determining a timing advance (TA) according to a delay variation rate indicated by a network device, during transmission of the UL shared channel; and
performing UL synchronization by using the TA and the one or more transmission gaps during the transmission of the UL shared channel.
