Abstract
Device coexistence within single user, multiple user, multiple access, and/or MIMO wireless communications. Different respective communication devices operating using different respective communication channels having different respective channel bandwidths may be implemented within a given communication system. For example, different respective communication devices may belong to different basic services sets (BSSs) (e.g., a 1 MHz BSS operating using channel bandwidths of 1 MHz, and a 2 MHz BSS operating using channel bandwidths of 2 MHz). To effectuate coexistence among different respective devices operating using different respective channel bandwidths, devices but longing to the 1 MHz BSS monitor for and listen for 2 MHz wide communication activity, and those 1 MHz BSS communication devices defer to any detected communication activity on any portion of the 2 MHz channel.
