1. A clock offset determination method, comprising:
determining a first positioning measurement value by measuring downlink positioning reference signals (PRSs) from a reference base station and a non-reference base station;
determining a first clock offset between the reference base station and the non-reference base station based on the first positioning measurement value; and
assisting a target terminal to obtain a second clock offset based on the first clock offset.
