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:

performing an assessment of a wireless network;
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;
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.

2. The method of claim 1 , wherein the primary segment, the secondary segment, the tertiary segment, and the quaternary segment are a continuous segment.

3. The method of claim 2 , wherein the first channel width field is a first value, the second channel width field is the first value, the third channel width field is a second value, the first center frequency field is a nonzero value and the second center frequency field is a center frequency of the continuous segment.

4. The method of claim 1 , wherein the primary segment and the secondary segment are continuous, and the tertiary segment and the quaternary segment are continuous.

5. The method of claim 4 , wherein the first channel width field is a first value, the second channel width field is the first value, the third channel width field is a second value, the first center frequency field is a nonzero value and the second center frequency field is a center frequency of the tertiary segment and the quaternary segment.

6. The method of claim 1 , wherein the management frame includes a new element, the new element including the second center frequency field, the third center frequency field and the third channel width field.

7. The method of claim 1 , further including transmitting a frame to one or more STAs, the frame including (1) information to enable simultaneous transmission of data packets from the one or more STAs and (2) a bandwidth field with one or more bits in a reserved subfield in a common info field.

8. A non-transitory computer readable storage medium comprising instructions which, when executed, cause a processor to at least:
perform an assessment of a wireless network;
determine 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;
create 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
transmit the management frame over the wireless network.

9. The non-transitory computer readable storage medium of claim 8 , wherein the primary segment, the secondary segment, the tertiary segment, and the quaternary segment are a continuous segment.

10. The non-transitory computer readable storage medium of claim 9 , wherein the first channel width field is a first value, the second channel width field is the first value, the third channel width field is a second value, the first center frequency field is a nonzero value and the second center frequency field is a center frequency of the continuous segment.

11. The non-transitory computer readable storage medium of claim 10 , wherein the primary segment and the secondary segment are continuous, and the tertiary segment and the quaternary segment are continuous.

12. The non-transitory computer readable storage medium of claim 11 , wherein the first channel width field is a first value, the second channel width field is the first value, the third channel width field is a second value, the first center frequency field is a nonzero value and the second center frequency field is a center frequency of the tertiary segment and the quaternary segment.

13. The non-transitory computer readable storage medium of claim 8 , wherein the management frame includes a new element, the new element including the second center frequency field, the third center frequency field and the third channel width field.

14. The non-transitory computer readable storage medium of claim 8 , wherein the instructions further cause the processor to transmit a frame to one or more STAs, the frame including (1) information to enable simultaneous transmission of data packets from the one or more STAs and (2) a bandwidth field with one or more bits in a reserved subfield in a common info field.

15. An apparatus, comprising:
a channel assessor to perform an assessment of a wireless network;
an application processor to determine 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;
a frame generator to create 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
radio architecture to transmit the management frame over the wireless network.

16. The apparatus of claim 15 , wherein the primary segment, the secondary segment, the tertiary segment, and the quaternary segment are a continuous segment.
