Foreword

ISO (the International Organization for Standardization) and IEC (the International Electrotechnical

Commission) form the specialized system for worldwide standardization. National bodies that are

members of ISO or IEC participate in the development of International Standards through technical

committees established by the respective organization to deal with particular fields of technical activity.

ISO and IEC technical committees collaborate in fields of mutual interest. Other international

organizations, governmental and non‐governmental, in liaison with ISO and IEC, also take part in the

work.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted (see www.iso.org/directives).

IEEE Standards documents are developed within the IEEE Societies and the Standards Coordinating

Committees of the IEEE Standards Association (IEEE‐SA) Standards Board. The IEEE develops its

standards through a consensus development process, approved by the American National Standards

Institute, which brings together volunteers representing varied viewpoints and interests to achieve the

final product. Volunteers are not necessarily members of the Institute and serve without compensation.

While the IEEE administers the process and establishes rules to promote fairness in the consensus

development process, the IEEE does not independently evaluate, test, or verify the accuracy of any of

the information contained in its standards.

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.

Details of any patent rights identified during the development of the document will be in the

Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents) or the

IEC list of patent declarations received (see http://patents.iec.ch).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT)

see www.iso.org/iso/foreword.html.

ISO/IEC/IEEE 8802‐11:2018/Amd 4 was prepared by the LAN/MAN of the IEEE Computer Society (as

IEEE Std 802.11ak‐2018) and drafted in accordance with its editorial rules. It was adopted, under the

“fast‐track procedure” defined in the Partner Standards Development Organization cooperation

agreement between ISO and IEEE, by Joint Technical Committee ISO/IEC JTC 1, Information technology,

Subcommittee SC 6, Telecommunications and information exchange between systems.

A list of all parts in the ISO/IEC/IEEE 8802 series can be found on the ISO website.

Important Notices and Disclaimers Concerning IEEE Standards Documents

IEEE documents are made available for use subject to important notices and legal disclaimers. These notices and

disclaimers, or a reference to this page, appear in all standards and may be found under the heading “Important Notices

and Disclaimers Concerning IEEE Standards Documents.” They can also be obtained on request from IEEE or viewed at

http://standards.ieee.org/IPR/disclaimers.html.
Notice and Disclaimer of Liability Concerning the Use of IEEE Standards
Documents

IEEE Standards documents (standards, recommended practices, and guides), both full-use and trial-use, are developed

within IEEE Societies and the Standards Coordinating Committees of the IEEE Standards Association (“IEEE-SA”)

Standards Board. IEEE (“the Institute”) develops its standards through a consensus development process, approved by

the American National Standards Institute (“ANSI”), which brings together volunteers representing varied viewpoints

and interests to achieve the final product. IEEE Standards are documents developed through scientific, academic, and

industry-based technical working groups. Volunteers in IEEE working groups are not necessarily members of the

Institute and participate without compensation from IEEE. While IEEE administers the process and establishes rules to

promote fairness in the consensus development process, IEEE does not independently evaluate, test, or verify the

accuracy of any of the information or the soundness of any judgments contained in its standards.

IEEE Standards do not guarantee or ensure safety, security, health, or environmental protection, or ensure against

interference with or from other devices or networks. Implementers and users of IEEE Standards documents are

responsible for determining and complying with all appropriate safety, security, environmental, health, and interference

protection practices and all applicable laws and regulations.

IEEE does not warrant or represent the accuracy or content of the material contained in its standards, and expressly

disclaims all warranties (express, implied and statutory) not included in this or any other document relating to the

standard, including, but not limited to, the warranties of: merchantability; fitness for a particular purpose; non-

infringement; and quality, accuracy, effectiveness, currency, or completeness of material. In addition, IEEE disclaim s

any and all conditions relating to: results; and workmanlike effort. IEEE standards documents are supplied “AS IS” and

“WITH ALL FAULTS.”

Use of an IEEE standard is wholly voluntary. The existence of an IEEE standard does not imply that there are no other

ways to produce, test, measure, purchase, market, or provide other goods and services related to the scope of the IEEE

standard. Furthermore, the viewpoint expressed at the time a standard is approved and issued is subject to change

brought about through developments in the state of the art and comments received from users of the standard.

In publishing and making its standards available, IEEE is not suggesting or rendering professional or other services for,

or on behalf of, any person or entity nor is IEEE undertaking to perform any duty owed by any other person or entity to

another. Any person utilizing any IEEE Standards document, should rely upon his or her own independent judgment in

the exercise of reasonable care in any given circumstances or, as appropriate, seek the advice of a competent

professional in determining the appropriateness of a given IEEE standard.
IN NO EVENT SHALL IEEE BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL,

EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING, BUT NOT LIMITED TO: PROCUREMENT O F

SUBSTITUTE GOODS OR SERVICES; LOSS OF USE, DATA, OR PROFITS; OR BUSINESS INTERRUPTION)

HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN CONTRACT, STRICT

LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE

PUBLICATION, USE OF, OR RELIANCE UPON ANY STANDARD, EVEN IF ADVISED OF THE POSSIBILITY

OF SUCH DAMAGE AND REGARDLESS OF WHETHER SUCH DAMAGE WAS FORESEEABLE.
Translations

The IEEE consensus development process involves the review of documents in English only. In the event that an IEEE

standard is translated, only the English version published by IEEE should be considered the approved IEEE standard.

Official statements

A statement, written or oral, that is not processed in accordance with the IEEE-SA Standards Board Operations Manual

shall not be considered or inferred to be the official position of IEEE or any of its committees and shall not be considere d

to be, or be relied upon as, a formal position of IEEE. At lectures, symposia, seminars, or educational courses, a n

individual presenting information on IEEE standards shall make it clear that his or her views should be considered the

personal views of that individual rather than the formal position of IEEE.
Comments on standards

Comments for revision of IEEE Standards documents are welcome from any interested party, regardless of membership

affiliation with IEEE. However, IEEE does not provide consulting information or advice pertaining to IEEE Standards

documents. Suggestions for changes in documents should be in the form of a proposed change of text, together with

appropriate supporting comments. Since IEEE standards represent a consensus of concerned interests, it is important that

any responses to comments and questions also receive the concurrence of a balance of interests. For this reason, IEEE

and the members of its societies and Standards Coordinating Committees are not able to provide an instant response to

comments or questions except in those cases where the matter has previously been addressed. For the same reason, IEE E

does not respond to interpretation requests. Any person who would like to participate in revisions to an IEEE standard is

welcome to join the relevant IEEE working group.
Comments on standards should be submitted to the following address:
Secretary, IEEE-SA Standards Board 

Piscataway, NJ 08854 USA
Laws and regulations

Users of IEEE Standards documents should consult all applicable laws and regulations. Compliance with the provisions

of any IEEE Standards document does not imply compliance to any applicable regulatory requirements. Implementers of

the standard are responsible for observing or referring to the applicable regulatory requirements. IEEE does not, by the

publication of its standards, intend to urge action that is not in compliance with applicable laws, and these documents

may not be construed as doing so.
Copyrights

IEEE draft and approved standards are copyrighted by IEEE under U.S. and international copyright laws. They are made

available by IEEE and are adopted for a wide variety of both public and private uses. These include both use, b y

reference, in laws and regulations, and use in private self-regulation, standardization, and the promotion of engineering

practices and methods. By making these documents available for use and adoption by public authorities and private

users, IEEE does not waive any rights in copyright to the documents.
Photocopies

Subject to payment of the appropriate fee, IEEE will grant users a limited, non-exclusive license to photocopy portions

of any individual standard for company or organizational internal use or individual, non-commercial use only. T o

arrange for payment of licensing fees, please contact Copyright Clearance Center, Customer Service, 222 Rosewood

Drive, Danvers, MA 01923 USA; +1 978 750 8400. Permission to photocopy portions of any individual standard for

educational classroom use can also be obtained through the Copyright Clearance Center.

Updating of IEEE Standards documents

Users of IEEE Standards documents should be aware that these documents may be superseded at any time by the

issuance of new editions or may be amended from time to time through the issuance of amendments, corrigenda, or

errata. A current IEEE document at any point in time consists of the current edition of the document together with any

amendments, corrigenda, or errata then in effect.

Every IEEE standard is subjected to review at least every ten years. When a document is more than ten years old and has

not undergone a revision process, it is reasonable to conclude that its contents, although still of some value, do no t

wholly reflect the present state of the art. Users are cautioned to check to determine that they have the latest edition of

any IEEE standard.

In order to determine whether a given document is the current edition and whether it has been amended through the

issuance of amendments, corrigenda, or errata, visit the IEEE-SA Website at http://ieeexplore.ieee.org or contact IEEE

at the address listed previously. For more information about the IEEE SA or IEEE’s standards development process,

visit the IEEE-SA Website at http://standards.ieee.org.
Errata

Errata, if any, for all IEEE standards can be accessed on the IEEE-SA Website at the following URL: http://

standards.ieee.org/findstds/errata/index.html. Users are encouraged to check this URL for errata periodically.

Patents

Attention is called to the possibility that implementation of this standard may require use of subject matter covered by

patent rights. By publication of this standard, no position is taken by the IEEE with respect to the existence or validity o f

any patent rights in connection therewith. If a patent holder or patent applicant has filed a statement of assurance via an

Accepted Letter of Assurance, then the statement is listed on the IEEE-SA Website at http://standards.ieee.org/about/

sasb/patcom/patents.html. Letters of Assurance may indicate whether the Submitter is willing or unwilling to gran t

licenses under patent rights without compensation or under reasonable rates, with reasonable terms and conditions that

are demonstrably free of any unfair discrimination to applicants desiring to obtain such licenses.

Essential Patent Claims may exist for which a Letter of Assurance has not been received. The IEEE is not responsible for

identifying Essential Patent Claims for which a license may be required, for conducting inquiries into the legal validity

or scope of Patents Claims, or determining whether any licensing terms or conditions provided in connection with

submission of a Letter of Assurance, if any, or in any licensing agreements are reasonable or non-discriminatory. Users

of this standard are expressly advised that determination of the validity of any patent rights, and the risk of infringemen t

of such rights, is entirely their own responsibility. Further information may be obtained from the IEEE Standards

Association.

Introduction

This introduction is not part of IEEE Std 802.11ak-2018, IEEE Standard for Information technology—Local and

metropolitan area networks—Specific requirements—Part 11: Wireless LAN MAC and PHY Specifications—

Amendment 3: Enhancements for Transit Links Within Bridged Networks.

IEEE Std 802.11™ was originally designed with the assumption that non-access point (non-AP) non-mesh

stations (STAs) would be leaf nodes of the network. This amendment extends IEEE Std 802.11 so that

communication links can be established between general link (GLK) STAs that are usable as transit link s

inside an IEEE 802.1Q™ network.
Areas of extension and related improvements include the following:

a) Optional support of IEEE 802 length/type (EPD) frame encoding, as opposed to ISO/IEC 8802-2 :

1998 logical link control (LLC) encoding (LPD).

b) Facilities for GLK APs to send group addressed Data GLK frames to a subset of receiving GLK

STAs.

c) Priority code points in IEEE Std 802.1Q™ have a different default meaning than they do i n

IEEE Std 802.1D™. For example, in IEEE Std 802.1Q, priority 2 is, by default, higher priority than

priority 1, while in IEEE Std 802.1D, it is lower. Thus it is suggested in Annex V that GLK

associations use a Priority code point to user priority mapping in their corresponding IEEE 802.1Q

bridge port.

d) Accessibility to the wireless medium via one or more Internal Sublayer Service service access points

(SAPs) that map to attached bridge ports.
e) Improvement of groupcast with retries (GCR) setup to extend GCR to GLK STAs.

Foreword

ISO (the International Organization for Standardization) and IEC (the International Electrotechnical

Commission) form the specialized system for worldwide standardization. National bodies that are

members of ISO or IEC participate in the development of International Standards through technical

committees established by the respective organization to deal with particular fields of technical activity.

ISO and IEC technical committees collaborate in fields of mutual interest. Other international

organizations, governmental and non‐governmental, in liaison with ISO and IEC, also take part in the

work.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted (see www.iso.org/directives).

IEEE Standards documents are developed within the IEEE Societies and the Standards Coordinating

Committees of the IEEE Standards Association (IEEE‐SA) Standards Board. The IEEE develops its

standards through a consensus development process, approved by the American National Standards

Institute, which brings together volunteers representing varied viewpoints and interests to achieve the

final product. Volunteers are not necessarily members of the Institute and serve without compensation.

While the IEEE administers the process and establishes rules to promote fairness in the consensus

development process, the IEEE does not independently evaluate, test, or verify the accuracy of any of

the information contained in its standards.

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.

Details of any patent rights identified during the development of the document will be in the

Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents) or the

IEC list of patent declarations received (see http://patents.iec.ch).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT)

see www.iso.org/iso/foreword.html.

ISO/IEC/IEEE 8802‐11:2018/Amd 4 was prepared by the LAN/MAN of the IEEE Computer Society (as

IEEE Std 802.11ak‐2018) and drafted in accordance with its editorial rules. It was adopted, under the

“fast‐track procedure” defined in the Partner Standards Development Organization cooperation

agreement between ISO and IEEE, by Joint Technical Committee ISO/IEC JTC 1, Information technology,

Subcommittee SC 6, Telecommunications and information exchange between systems.

A list of all parts in the ISO/IEC/IEEE 8802 series can be found on the ISO website.

Important Notices and Disclaimers Concerning IEEE Standards Documents

IEEE documents are made available for use subject to important notices and legal disclaimers. These notices and

disclaimers, or a reference to this page, appear in all standards and may be found under the heading “Important Notices

and Disclaimers Concerning IEEE Standards Documents.” They can also be obtained on request from IEEE or viewed at

http://standards.ieee.org/IPR/disclaimers.html.
Notice and Disclaimer of Liability Concerning the Use of IEEE Standards
Documents

IEEE Standards documents (standards, recommended practices, and guides), both full-use and trial-use, are developed

within IEEE Societies and the Standards Coordinating Committees of the IEEE Standards Association (“IEEE-SA”)

Standards Board. IEEE (“the Institute”) develops its standards through a consensus development process, approved by

the American National Standards Institute (“ANSI”), which brings together volunteers representing varied viewpoints

and interests to achieve the final product. IEEE Standards are documents developed through scientific, academic, and

industry-based technical working groups. Volunteers in IEEE working groups are not necessarily members of the

Institute and participate without compensation from IEEE. While IEEE administers the process and establishes rules to

promote fairness in the consensus development process, IEEE does not independently evaluate, test, or verify the

accuracy of any of the information or the soundness of any judgments contained in its standards.

IEEE Standards do not guarantee or ensure safety, security, health, or environmental protection, or ensure against

interference with or from other devices or networks. Implementers and users of IEEE Standards documents are

responsible for determining and complying with all appropriate safety, security, environmental, health, and interference

protection practices and all applicable laws and regulations.

IEEE does not warrant or represent the accuracy or content of the material contained in its standards, and expressly

disclaims all warranties (express, implied and statutory) not included in this or any other document relating to the

standard, including, but not limited to, the warranties of: merchantability; fitness for a particular purpose; non-

infringement; and quality, accuracy, effectiveness, currency, or completeness of material. In addition, IEEE disclaim s

any and all conditions relating to: results; and workmanlike effort. IEEE standards documents are supplied “AS IS” and

“WITH ALL FAULTS.”

Use of an IEEE standard is wholly voluntary. The existence of an IEEE standard does not imply that there are no other

ways to produce, test, measure, purchase, market, or provide other goods and services related to the scope of the IEEE

standard. Furthermore, the viewpoint expressed at the time a standard is approved and issued is subject to change

brought about through developments in the state of the art and comments received from users of the standard.

In publishing and making its standards available, IEEE is not suggesting or rendering professional or other services for,

or on behalf of, any person or entity nor is IEEE undertaking to perform any duty owed by any other person or entity to

another. Any person utilizing any IEEE Standards document, should rely upon his or her own independent judgment in

the exercise of reasonable care in any given circumstances or, as appropriate, seek the advice of a competent

professional in determining the appropriateness of a given IEEE standard.
IN NO EVENT SHALL IEEE BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL,

EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING, BUT NOT LIMITED TO: PROCUREMENT O F

SUBSTITUTE GOODS OR SERVICES; LOSS OF USE, DATA, OR PROFITS; OR BUSINESS INTERRUPTION)

HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN CONTRACT, STRICT

LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE

PUBLICATION, USE OF, OR RELIANCE UPON ANY STANDARD, EVEN IF ADVISED OF THE POSSIBILITY

OF SUCH DAMAGE AND REGARDLESS OF WHETHER SUCH DAMAGE WAS FORESEEABLE.
Translations

The IEEE consensus development process involves the review of documents in English only. In the event that an IEEE

standard is translated, only the English version published by IEEE should be considered the approved IEEE standard.

Official statements

A statement, written or oral, that is not processed in accordance with the IEEE-SA Standards Board Operations Manual

shall not be considered or inferred to be the official position of IEEE or any of its committees and shall not be considere d

to be, or be relied upon as, a formal position of IEEE. At lectures, symposia, seminars, or educational courses, a n

individual presenting information on IEEE standards shall make it clear that his or her views should be considered the

personal views of that individual rather than the formal position of IEEE.
Comments on standards

Comments for revision of IEEE Standards documents are welcome from any interested party, regardless of membership

affiliation with IEEE. However, IEEE does not provide consulting information or advice pertaining to IEEE Standards

documents. Suggestions for changes in documents should be in the form of a proposed change of text, together with

appropriate supporting comments. Since IEEE standards represent a consensus of concerned interests, it is important that

any responses to comments and questions also receive the concurrence of a balance of interests. For this reason, IEEE

and the members of its societies and Standards Coordinating Committees are not able to provide an instant response to

comments or questions except in those cases where the matter has previously been addressed. For the same reason, IEE E

does not respond to interpretation requests. Any person who would like to participate in revisions to an IEEE standard is

welcome to join the relevant IEEE working group.
Comments on standards should be submitted to the following address:
Secretary, IEEE-SA Standards Board 

Piscataway, NJ 08854 USA
Laws and regulations

Users of IEEE Standards documents should consult all applicable laws and regulations. Compliance with the provisions

of any IEEE Standards document does not imply compliance to any applicable regulatory requirements. Implementers of

the standard are responsible for observing or referring to the applicable regulatory requirements. IEEE does not, by the

publication of its standards, intend to urge action that is not in compliance with applicable laws, and these documents

may not be construed as doing so.
Copyrights

IEEE draft and approved standards are copyrighted by IEEE under U.S. and international copyright laws. They are made

available by IEEE and are adopted for a wide variety of both public and private uses. These include both use, b y

reference, in laws and regulations, and use in private self-regulation, standardization, and the promotion of engineering

practices and methods. By making these documents available for use and adoption by public authorities and private

users, IEEE does not waive any rights in copyright to the documents.
Photocopies

Subject to payment of the appropriate fee, IEEE will grant users a limited, non-exclusive license to photocopy portions

of any individual standard for company or organizational internal use or individual, non-commercial use only. T o

arrange for payment of licensing fees, please contact Copyright Clearance Center, Customer Service, 222 Rosewood

Drive, Danvers, MA 01923 USA; +1 978 750 8400. Permission to photocopy portions of any individual standard for

educational classroom use can also be obtained through the Copyright Clearance Center.

Updating of IEEE Standards documents

Users of IEEE Standards documents should be aware that these documents may be superseded at any time by the

issuance of new editions or may be amended from time to time through the issuance of amendments, corrigenda, or

errata. A current IEEE document at any point in time consists of the current edition of the document together with any

amendments, corrigenda, or errata then in effect.

Every IEEE standard is subjected to review at least every ten years. When a document is more than ten years old and has

not undergone a revision process, it is reasonable to conclude that its contents, although still of some value, do no t

wholly reflect the present state of the art. Users are cautioned to check to determine that they have the latest edition of

any IEEE standard.

In order to determine whether a given document is the current edition and whether it has been amended through the

issuance of amendments, corrigenda, or errata, visit the IEEE-SA Website at http://ieeexplore.ieee.org or contact IEEE

at the address listed previously. For more information about the IEEE SA or IEEE’s standards development process,

visit the IEEE-SA Website at http://standards.ieee.org.
Errata

Errata, if any, for all IEEE standards can be accessed on the IEEE-SA Website at the following URL: http://

standards.ieee.org/findstds/errata/index.html. Users are encouraged to check this URL for errata periodically.

Patents

Attention is called to the possibility that implementation of this standard may require use of subject matter covered by

patent rights. By publication of this standard, no position is taken by the IEEE with respect to the existence or validity o f

any patent rights in connection therewith. If a patent holder or patent applicant has filed a statement of assurance via an

Accepted Letter of Assurance, then the statement is listed on the IEEE-SA Website at http://standards.ieee.org/about/

sasb/patcom/patents.html. Letters of Assurance may indicate whether the Submitter is willing or unwilling to gran t

licenses under patent rights without compensation or under reasonable rates, with reasonable terms and conditions that

are demonstrably free of any unfair discrimination to applicants desiring to obtain such licenses.

Essential Patent Claims may exist for which a Letter of Assurance has not been received. The IEEE is not responsible for

identifying Essential Patent Claims for which a license may be required, for conducting inquiries into the legal validity

or scope of Patents Claims, or determining whether any licensing terms or conditions provided in connection with

submission of a Letter of Assurance, if any, or in any licensing agreements are reasonable or non-discriminatory. Users

of this standard are expressly advised that determination of the validity of any patent rights, and the risk of infringemen t

of such rights, is entirely their own responsibility. Further information may be obtained from the IEEE Standards

Association.

Introduction

This introduction is not part of IEEE Std 802.11ak-2018, IEEE Standard for Information technology—Local and

metropolitan area networks—Specific requirements—Part 11: Wireless LAN MAC and PHY Specifications—

Amendment 3: Enhancements for Transit Links Within Bridged Networks.

IEEE Std 802.11™ was originally designed with the assumption that non-access point (non-AP) non-mesh

stations (STAs) would be leaf nodes of the network. This amendment extends IEEE Std 802.11 so that

communication links can be established between general link (GLK) STAs that are usable as transit link s

inside an IEEE 802.1Q™ network.
Areas of extension and related improvements include the following:

a) Optional support of IEEE 802 length/type (EPD) frame encoding, as opposed to ISO/IEC 8802-2 :

1998 logical link control (LLC) encoding (LPD).

b) Facilities for GLK APs to send group addressed Data GLK frames to a subset of receiving GLK

STAs.

c) Priority code points in IEEE Std 802.1Q™ have a different default meaning than they do i n

IEEE Std 802.1D™. For example, in IEEE Std 802.1Q, priority 2 is, by default, higher priority than

priority 1, while in IEEE Std 802.1D, it is lower. Thus it is suggested in Annex V that GLK

associations use a Priority code point to user priority mapping in their corresponding IEEE 802.1Q

bridge port.

d) Accessibility to the wireless medium via one or more Internal Sublayer Service service access points

(SAPs) that map to attached bridge ports.
e) Improvement of groupcast with retries (GCR) setup to extend GCR to GLK STAs.
