Device coexistence within single user, multiple user, multiple access, and/or MIMO wireless communications

摘要

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.

主权项

1. An apparatus comprising:
a physical layer (PHY) processor configured to:
support communications with the at least one additional apparatus in accordance with a plurality of channel bandwidths, such that a first of the plurality of channel bandwidths is a sub-channel of a second of the plurality of channel bandwidths;continuously to monitor one of the plurality of channel bandwidths for communication activity thereon; and a baseband processor configured to:
analyze at least one signal received from the at least one additional apparatus, or at least one additional signal corresponding to the at least one signal, to identify any communication activity on any one of the plurality of channel bandwidths;selectively direct the apparatus not to transmit any signal for a period of time when communication activity identified on any one of the plurality of channel bandwidths or allow the apparatus to support the communications with the at least one additional apparatus when no communication activity identified on any one of the plurality of channel bandwidths; anddecode the at least one signal, or the at least one additional signal corresponding to the at least one signal, to extract at least one of preamble and signal field (SIG) information therein; andbased on the at least one of preamble and SIG information, selectively decode or not decode a remainder of the at least one signal, or the at least one additional signal corresponding to the at least one signal, following the at least one of preamble and SIG information.
