Claim:
1. A method comprising: defining, by a radio access network (RAN) device, a time-division multiplexed, orthogonal frequency-division multiplexed wireless air interface containing a primary signaling channel, wherein the primary signaling channel is formed by a first set of modulation symbols that are allocated to a fixed time position of each time-division multiplexed subframe across a plurality of contiguous subcarrier frequencies, wherein transmissions on a first set of the subcarrier frequencies are at a first power level and transmissions on a second set of subcarrier frequencies are at a second power level, and wherein the first and second sets of the subcarrier frequencies do not overlap; defining, by the RAN device, a secondary signaling channel, wherein the secondary signaling channel is formed in the air interface by a second set of modulation symbols that are allocated to dynamic time positions on the first set of the subcarrier frequencies; and transmitting signaling messages to one or more wireless communication devices (WCDs) via the secondary signaling channel of the air interface.
