Abstract
An example embodiment may involve defining an orthogonal frequency-division multiplexed (OFDM) wireless air interface that contains time-division multiplexed subframes. A primary signaling channel may be formed by modulation symbols that are statically allocated to fixed time positions of each subframe, and span contiguous subcarrier frequencies. A secondary signaling channel may be defined in the OFDM wireless air interface. The secondary signaling channel may be formed by modulation symbols that are dynamically allocated to time positions of one or more subcarrier frequencies, and span at least two consecutive subframes of the OFDM wireless air interface. A signaling message may be transmitted, on the primary signaling channel, to one or more WCDs. The signaling message may be transmitted in a first subframe of the consecutive subframes, and may identify the secondary signaling channel.
