Abstract

A wireless device (100) communicates in a wireless system by selecting a communication channel (202) for communication, identifying a control channel or control channels (204) designated for communication of control information for the selected communication channel, and listening for the control information (212) on the control channel to determine if the selected communication channel is bonded with any other communication channel. When control information is received via the control channel(s) indicating that the selected communication channel is bonded with at least one other communication channel, then the wireless device abstains from communication on the selected communication channel, or communicates in a narrowband mode. When control information is received via the control channel(s) indicating that the selected communication channel is not bonded with another communication channel, or when no control information is received via the control channel, then the wireless device communicates via the selected communication channel.
