Method and device for performing energy detection on a subset of a wireless channel

A device comprising:

• one or more processors;
• a non-transitory memory;
• and
• one or more programs stored in the non-transitory memory, which, when executed by the one or more processors, cause the device to:
• obtain an indication of a mode selection, wherein the mode selection indicates a particular number of overlapping portions of a first channel and a second channel on which to perform energy detection;
• adjust one or more operating parameters of the device based on the mode selection;
• perform energy detection on the particular number of overlapping portions of the first channel and the second channel based on the mode selection, wherein the first channel has a first bandwidth and the second channel has a second bandwidth, wherein an overlapping portion of the first and second channels is smaller than the first bandwidth of the first channel, and wherein the energy detection is performed at a center frequency of the first channel;
• determine whether a detected energy level from the energy detection satisfies a threshold, wherein the threshold characterizes an acceptable throughput level associated with the first channel;
• and
• transmit a signal over the first channel based on the threshold being satisfied.
