Abstract

Certain aspects of the present disclosure generally relate to techniques and apparatus for determining a primary channel for wireless communication. According to certain aspects, a method is provided for wireless communications by an apparatus. The method generally includes obtaining an information element (IE) with one or more parameters and computing a primary channel location to be used for the wireless communication, as a function of the one or more parameters, wherein the function is independent of a geographical area in which the apparatus is located.

Claims

1. An apparatus for wireless communication, comprising:

an interface configured to obtain an information element (IE) comprising a plurality of parameters; and

a processing system configured to compute a primary channel location to be used for the wireless communication, wherein the computation is based on the plurality of parameters and a function that is independent of a geographical area in which the apparatus is located, wherein the plurality of parameters comprise;

one or more operating class parameter in a first field of the IE; and

a channel width parameter in a second field of the IE; and

another interface configured to output for transmission a signal based on the computed primary channel location.

2. The apparatus of claim 1, wherein the processing system is configured to:

determine a starting frequency for the wireless communication based on a first parameter of the plurality of parameters; and

determine an offset with respect to the starting frequency based on a second parameter of the plurality of parameters.

3. The apparatus of claim 2, wherein the processing system is configured to determine the starting frequency for the wireless communication based on the first parameter of the plurality of parameters by determining a mapping of the first parameter to the starting frequency.

4. The apparatus of claim 1, wherein the processing system is configured to:

determine a channel width based on the channel width parameter.

5. The apparatus of claim 2, wherein:

the second parameter comprises an index; and

the processing system is configured to determine the offset based on the index and a frequency constant.

6. The apparatus of claim 1, wherein the plurality of parameters further comprise:

an index field in a third field of the IE.

7. The apparatus of claim 6, wherein different values of the first operating class parameter map to different combinations of values for a set of operating parameters.

8. The apparatus of claim 7, wherein the set of operating parameters comprise at least two of:

a channel starting frequency, a channel center frequency index, or limits on behavior of the apparatus.

9. A method for wireless communication by an apparatus, comprising:

obtaining an information element (IE) comprising a plurality of parameters;

computing a primary channel location to be used for the wireless communication by an apparatus, wherein the computation is based on the plurality of parameters and a function that is independent of a geographical area in which the apparatus is located, wherein the plurality of parameters comprise;

one or more operating class parameter in a first field of the IE; and

a channel width parameter in a second field of the IE; and

outputting for transmission a signal based on the computed primary channel location.

10. The method of claim 9, further comprising:

determining a starting frequency for the wireless communication based on a first parameter of the plurality of parameters; and

determining an offset with respect to the starting frequency based on a second parameter of the plurality of parameters.

11. The method of claim 10, further comprising:

determining the starting frequency for the wireless communication based on the first parameter of the plurality of parameters by determining a mapping of the first parameter to the starting frequency.

12. The method of claim 9, further comprising:

determining a channel width based on the channel width parameter.

13. The method of claim 10, wherein:

the second parameter comprises an index; and

determining the offset comprises determining the offset based on the index and a frequency constant.

14. The method of claim 9, wherein the plurality of parameters further comprise:

an index field in a third field of the IE.

15. The method of claim 14, wherein different values of the first operating class parameter map to different combinations of values for a set of operating parameters.

16. The method of claim 15, wherein the set of operating parameters comprise at least two of:

a channel starting frequency, a channel center frequency index, or limits on behavior of the apparatus.

17. A non-transitory computer readable medium having instructions stored thereon for:

obtaining an information element (IE) comprising a plurality of parameters; and

computing a primary channel location to be used for the wireless communication by an apparatus, wherein the computation is based on the plurality of parameters and a function that is independent of a geographical area in which the apparatus is located, wherein the plurality of parameters comprise;

one or more operating class parameter in a first field of the IE; and

a channel width parameter in a second field of the IE; and

outputting for transmission a signal based on the computed primary channel location.

18. A station for wireless communications, comprising:
