By publication of this standard, no position is taken with respect to the existence or validity of any patent rights in connection therewith. The IEEE shall not be responsible for identifying patents or patent applications for which a license may be required to implement an IEEE standard or for conducting inquiries into the legal validity or scope of those patents that are brought to its attention. A patent holder or patent applicant has filed a statement of assurance that it will grant licenses under these rights without compensation or under reasonable rates and nondiscriminatory, reasonable terms and conditions to applicants desiring to obtain such licenses. The IEEE makes no representation as to the reasonableness of rates, terms, and conditions of the license agreements offered by patent holders or patent applicants.

The RegLoc DSE bit field is set to 1 to report that the enabling STA is enabling the operation of STAs with DSE; otherwise, it is 0. The Dependent STA bit field is set to 1 to report that the STA is operating with the enablement of the enabling STA whose LCI is being reported; otherwise, it is 0. The Dependent Enablement Identifier field is a 16-bit field with a value set by the enabling STA via the DSE Enablement frame; otherwise, it is set to 0. The Regulatory Class field indicates the channel set for which the enablement request, report, or announcement applies. The Regulatory Class and Channel Number fields together specify the channel frequency and channel bandwidth for which the report applies. Valid values for the Regulatory Class field are shown in Annex J. The Channel Number field indicates the channel number for which the enablement request, report, or announcement applies. The channel number is defined within a regulatory class as shown in Annex J.

The format of the Extended Channel Switch Announcement element is shown in Figure 7-95o13. Figure 7-95o13Extended Channel Switch Announcement element format The Length field is set to 4. The Channel Switch Mode field indicates any restrictions on transmission until a channel switch. An AP in a BSS or a STA in an IBSS sets the Channel Switch Mode field to either 0 or 1 on transmission as specified in 11.9.7.1 and 11.9.7.2. The New Regulatory Class field is set to the number of the regulatory class after the channel switch, as defined in Annex J. The New Channel Number field is set to the number of the channel after the channel switch. The channel number is a channel from the STAs new regulatory class as defined in Annex J. The Channel Switch Count field indicates either the number of target beacon transmission times (TBTTs) until the STA sending the Extended Channel Switch Announcement element switches to the new channel or a value of zero. A value of one indicates that the switch occurs immediately before the next TBTT. A value of zero indicates that the switch occurs anytime after the frame containing the element is transmitted. 7.3.2.54 Supported Regulatory Classes element The Supported Regulatory Classes element is used by a STA to advertise the regulatory classes that it is capable of operating with in this country. The format of the Supported Regulatory Classes element is shown in Figure 7-95o14. Figure 7-95o14Supported Regulatory Classes element format The value of the Length field of the Supported Regulatory Classes element is between 2 and 253. The Current Regulatory Class octet indicates the regulatory class in use for transmission and reception. The List of Regulatory Class(es) field lists in ascending order all regulatory classes that the STA is capable of operating with in this country. The use of this element is described in 11.9a.1. 7.4 Action frame format details 7.4.7 Public Action details 7.4.7.1 Public Action frames Change Table 7-57e as shown: Element ID Length Channel Switch Mode New Regulatory Class New Channel Number Channel Switch Count Octets: 111111 Element ID Length Current Regulatory Class List of Regulatory Class(es) Octets:111Length-1 Authorized licensed use limited to: IHS Stephanie Dejesus.

It is transmitted by a STA as part of enablement. The format of the DSE Enablement frame body is shown in Figure 7-101h1. Figure 7-101h1DSE Enablement frame body format The Category field is set to the value for public action defined in Table 7-24. The Action Value field is set to indicate a DSE Enablement frame, as defined in Table 7-57e. The RequesterSTAAddress field is the MAC address of the requesting STA that initiates the enablement process. The length of the RequesterSTAAddress field is 6 octets. The ResponderSTAAddress field is the MAC address of the responding STA that grants enablement. The length of the ResponderSTAAddress field is 6 octets. The Reason Result Code field is used to indicate the reason that a DSE Enablement frame was generated. The length of the Reason Result Code field is 1 octet. The reason result codes that have been allocated are shown in Table 7-57f1. Table 7-57ePu
