1. A method for communicating with a narrow bandwidth wireless device in a broadband network, comprising:

  • retrieving at least one of secondary narrow bandwidth device region (NBDR) configuration information or primary NBDR configuration information from a primary NBDR, wherein the primary NBDR and the secondary NBDR are located in a physical downlink shared channel (PDSCH) region of a subframe and are subsets of frequency resources within a wide bandwidth subframe, and at least one of the primary NBDR and the secondary NBDR includes both an NBDR-control channel and an NBDR data channel; and

    receiving data in at least one of the primary NBDR and the secondary NBDR based on the configuration information, wherein the primary NBDR is located in a central part of a signal bandwidth spectrum including a direct current (DC) subcarrier, and the secondary NBDR uses frequency resources within the subframe not used by the primary NBDR.
