Abstract

Methods, apparatus, systems and articles of manufacture are disclosed to generate a management frame identifying an operation mode for a basic service set of a local area network. An example disclosed method includes performing an assessment of a wireless network and determining an operation mode for a basic service set (BSS) bandwidth based on the assessment, the operation mode indicating continuity of a primary segment, a secondary segment, a tertiary segment and a quaternary segment. The example method further includes creating a management frame including information fields based on the BSS bandwidth, the information fields including a first channel width field, a second channel width field, a third channel width field, a first center frequency field, a second center frequency field and a third center frequency field and transmitting the management frame over the wireless network.

First claim

What is claimed is:

1 . An apparatus, comprising:
machine readable instructions; programmable circuitry to at least one of instantiate or execute the machine readable instructions to:
create a management frame based on a basic service set (BSS) bandwidth of 320 megahertz (MHz), the management frame including a channel width field, a first center frequency field, and a second center frequency field, the BSS bandwidth being a contiguous 320 MHz channel, the contiguous 320 MHz channel including a primary 160 MHz channel and a secondary 160 MHz channel and the first center frequency field indicates a center frequency index of the primary 160 MHz channel, the second center frequency field indicates a center frequency index of the contiguous 320 MHz channel; and
transmit the management frame over a wireless network.

2 . The apparatus of claim 1 , wherein the BSS bandwidth is in a 6 gigahertz (GH) band.

3 . The apparatus of claim 1 , wherein the channel width field indicates the BSS bandwidth has a total channel bandwidth of 320 MHz.

4 . The apparatus of claim 3 , wherein the channel width field has a non-zero value.

5 . A non-transitory machine readable storage medium comprising instructions to cause programmable circuitry to at least:
create a management frame based on a basic service set (BSS) bandwidth of 320 megahertz (MHz), the management frame including a channel width field, a first center frequency field, and a second center frequency field, the BSS bandwidth being a contiguous 32 MHz channel, the contiguous 320 MHz channel including a primary 160 MHz channel and a secondary 160 MHz channel and the first center frequency field indicates a center frequency index of the primary 160 MHz channel, the second center frequency field indicates a center frequency index of the contiguous 320 MHz channel; and transmit the management frame over a wireless network.

6 . The non-transitory machine readable storage medium of claim 5 , wherein the BSS bandwidth is in a 6 gigahertz (GH) band.

7 . The non-transitory machine readable storage medium of claim 5 , wherein the channel width field indicates the BSS bandwidth has a total channel bandwidth of 320 MHz.

8 . The non-transitory machine readable storage medium of claim 7 , wherein the channel width field has a non-zero value.

9 . A method, comprising:
creating a management frame based on a basic service set (BSS) bandwidth of 320 megahertz (MHz), the management frame including a channel width field, a first center frequency field, and a second center frequency field, the BSS bandwidth being a contiguous 320 MHz channel, the contiguous 320 MHz channel including a primary 160 MHz channel and a secondary 160 MHz channel and the first center frequency field indicates a center frequency index of the primary 160 MHz channel, the second center frequency field indicates a center frequency index of the contiguous 320 MHz channel; and transmitting the management frame over a wireless network.

10 . The method of claim 9 , wherein the BSS bandwidth is in a 6 gigahertz (GH) band.

11 . The method of claim 9 , wherein the channel width field indicates the BSS bandwidth has a total channel bandwidth of 320 MHz.
