1. A method comprising:

  • dividing radio frequencies of a wireless communication system into a wideband channel radio frequency and a plurality of narrowband channel radio frequencies; and

    communicating user data using a same modulation technique to an apparatus using both the wideband channel radio frequency and the plurality of narrowband channel radio frequencies in the wireless communication system;

    wherein the wireless communication system is configured to select between use of the wideband channel radio frequency and use of at least one of the plurality of narrowband channel radio frequencies for communication of the user data, wherein the selection comprises a determination as to whether a wideband frequency or, alternatively, a narrowband frequency, is to be selected, with the determination being based on whether the apparatus is in a cell boundary region.
