Embodiments of a communication station and method for communicating in a wireless network are generally described herein. In some embodiments, the communication station may be configured to communicate orthogonal frequency division multiplexed (OFDM) symbols on channel resources in accordance with an orthogonal frequency division multiple access (OFDMA) technique during a control period. The channel resources may comprise one or more minimum bandwidth units. Each minimum bandwidth unit may have a predetermined bandwidth and may be configured in accordance with one of a plurality of subcarrier allocations for one of a plurality of interleaver configurations.
