1. A method for a wireless receiver to synchronize a clock, the method comprising:
a) receiving a timing signal in a resource element, the resource element comprising a subcarrier and a symbol-time, the timing signal comprising a first portion followed by a second portion, wherein the first portion comprises a first modulation and the second portion comprises a second modulation different from the first modulation;
b) determining a timestamp point comprising an interface between the first modulation and the second modulation;
c) determining a time of the timestamp point relative to a beginning or an ending of the symbol-time; and
d) adjusting a clock according to the time of the timestamp point.
