Abstract
A wireless communication device to facilitate determination of frequency band information comprises a processing system and a wireless communication transceiver. The processing system is configured to identify a carrier frequency stored within the wireless communication device and determine a direct current (DC) subcarrier associated with the carrier frequency. The wireless communication transceiver is configured to synchronize with the DC subcarrier to obtain channel information, wherein the channel information comprises a channel size and a DC subcarrier offset. The processing system is configured to process the DC subcarrier with the DC subcarrier offset to determine a starting frequency of a frequency band associated with the carrier frequency.
