Claim 0:
1. A method for a base station of a wireless network, the method comprising:
a) determining a resource grid comprising symbol-times in time and subcarriers in frequency, wherein each symbol-time is bounded in time by two symbol boundaries;
b) broadcasting, in a system information message, a schedule or formula indicating times at which the base station is to transmit a timing signal; and
c) broadcasting the timing signal, on a predetermined subcarrier, at a particular symbol-time according to the schedule or formula;
d) wherein the timing signal comprises a first modulation in a first portion of the particular symbol-time, followed by a second modulation, different from the first modulation, in a second portion of the particular symbol-time; and
e) wherein the timing signal changes from the first modulation to the second modulation at a midpoint of the particular symbol-time, wherein the midpoint of the particular symbol-time is equidistant in time between the two symbol boundaries of the particular symbol-time.
