Abstract
This disclosure describes methods, apparatus, and systems related to non-contiguous channel bonding. A device may determine a wireless communication channel having one or more subchannels in accordance with one or more communication standards. The device may determine instructions to perform one or more clear channel assessments (CCAs) on at least one of the one or more subchannels. The device may cause to send the instructions to one or more first devices. The device may identify a frame received from at least one of the one or more first devices, wherein the frame is received on at least one available subchannel of the one or more subchannels.
Claims20
An apparatus for a station device, the apparatus comprising processing circuitry coupled to storage, the processing circuitry configured to:
- encode a high efficiency (HE) frame for transmission to one or more EHT stations (STAs), wherein the HE frame is transmitted on a channel comprising at least one of:
- a first 80 MHz channel bandwidth, where a first secondary 20 MHz subchannel is punctured while a first secondary 40 MHz subchannel is idle,
- a second 80 MHz channel bandwidth, where a first 20 MHz subchannel of a second secondary 40 MHz subchannel is punctured while a second 20 MHz subchannel of the second secondary 40 MHz subchannel and a third 20 MHz subchannel are idle,
- a first 160 MHz channel bandwidth or a first 80+80 MHz channel bandwidth, where in a first primary 80 MHz subchannel, a fourth secondary 20 MHz subchannel is punctured while a third secondary 40 MHz subchannel and at least one of four 20 MHz subchannels in a first secondary 80 MHz channel are idle, and
- a second 160 MHz channel bandwidth or a second 80+80 MHz channel bandwidth, where in a second primary 80 MHz subchannel, a primary 40 MHz is present while a fourth secondary 20 MHz channel and at least one of four 20 MHz subchannels in a second secondary 80 MHz channel are idle;
- perform a Clear Channel Assessment (CCA) measurement on primary 20MHz subchannel, secondary 20 MHz subchannel, or the secondary 40 MHz subchannel for the 80 MHz channel bandwidth, and on primary 20 MHz subchannel, secondary 20MHz subchannel, secondary 40 MHz subchannel, or the secondary 80 MHz subchannel for the 160 MHz channel bandwidth;
- and
- cause to send the HE frame on at least a primary subchannel and a secondary subchannel even though at least one or more subchannels are punctured.

A non-transitory computer-readable medium storing computer-executable instructions which when executed by one or more processors result in performing operations comprising:
- encoding a high efficiency (HE) frame for transmission to one or more EHT stations (STAs), wherein the HE frame is transmitted on a channel comprising at least one of:
- a first 80 MHz channel bandwidth, where a first secondary 20 MHz subchannel is punctured while a first secondary 40 MHz subchannel is idle,

- a second 160 MHz channel bandwidth or a second 80+80 MHz channel bandwidth, where in a second primary 80 MHz subchannel, a primary 40 MHz is present while a fourth secondary 20 MHz channel and at least one of four 20 MHz subchannels in a second secondary 80 MHz channel are idle;
- performing a Clear Channel Assessment (CCA) measurement on primary 20MHz subchannel, secondary 20 MHz subchannel, or the secondary 40 MHz subchannel for the 80 MHz channel bandwidth, and on primary 20 MHz subchannel, secondary 20MHz subchannel, secondary 40 MHz subchannel, or the secondary 80 MHz subchannel for the 160 MHz channel bandwidth;
- and
- causing to send the HE frame on at least a primary subchannel and a secondary subchannel even though at least one or more subchannels are punctured.
